Euronext Paris, formerly known as the Paris Bourse (French: Bourse de Paris), is a regulated securities trading venue in France. It is Europe's second largest stock exchange by market capitalization, behind the London Stock Exchange, as of December 2023.[2][3] As of 2022, the 795 companies listed had a combined market capitalization of over US$4.58 trillion.[1]

Key Information

Since September 2000, the Paris Bourse has been part of Euronext, of which it was a co-founder together with the Amsterdam Stock Exchange and Brussels Stock Exchange. It was subsequently rebranded Euronext Paris.

History

The Paris stock market started taking shape in the early 18th century, and first acquired prominence with trading of John Law's Company from 1717 to 1721. In 1724, a government decree gave it its first permanent regulation and is occasionally though dubiously taken as the market's starting point.

On 5 March 1886, anarchist Charles Gallo targeted it during the Paris Stock Exchange bombing, a propaganda of the deed attack.[4] He entered the building, threw a bomb that failed to explode, and then began shooting at the traders who were selling government bonds.[4]

From the second half of the 19th century, official stock markets in Paris were operated by the Compagnie des agents de change, directed by the elected members of a stockbrokers' syndical council. The number of dealers in each of the different trading areas of the Bourse was limited. There were around 60 agents de change (the official stockbrokers). An agent de change had to be a French citizen, be nominated by a former agent or his estate, and be approved by the Minister of Finance, and he was appointed by decree of the President of the Republic. Officially, the agents de change could not trade for their own account nor even be a counterpart to someone who wanted to buy or sell securities with their aid; they were strictly brokers, that is, intermediaries. In the financial literature, the Paris Bourse is hence referred to as order-driven market, as opposed to quote-driven markets or dealer markets, where price-setting is handled by a dealer or market-maker. In Paris, only agents de change could receive a commission, at a rate fixed by law, for acting as an intermediary. However, parallel arrangements were usual in order to favor some clients' quote[clarification needed]. The Commodities Exchange was housed in the same building until 1889, when it moved to the present Bourse de commerce.[5] Moreover, until about the middle of the 20th century, a parallel market known as "La Coulisse" was in operation.[6]

Until the late 1980s, the market operated as an open outcry exchange, with the agents de change meeting on the exchange floor of the Palais Brongniart. In 1986, the Paris Bourse started to implement an electronic trading system. This was known generically as CATS (Computer Assisted Trading System), but the Paris version was called CAC (Cotation Assistée en Continu). By 1989, quotations were fully automated. The Palais Brongniart hosted the French financial derivatives exchanges MATIF and MONEP, until they were fully automated in 1998.

In 1988, new legislation was adopted that radically reformed the governance of the Paris stock exchange. Its ownership was transferred to the former Compagnie des agents de change [fr] ("brokers' society"), which, on the occasion renamed itself as the Société des Bourses Françaises (SBF, "French Stock Exchange Company"). In 1999, the SBF absorbed what remained of MATIF and MONEP and altered its name to Paris Bourse-SBF.[7] The next year, SBF was a leading participant of the merger that formed Euronext.

Past locations

[edit]

The Paris securities markets first emerged in rue Quincampoix, a small street near les Halles in Paris, in the early 18th century. It remained on rue Quincampoix until closed by government decision on 22 March 1720, at a time when most of its activity was focused on trading the shares and other securities of John Law's Company. The turmoil of that year and gradual unraveling of Law's system was accompanied by several relocations of the market, first to the place Vendôme then to the garden of the Hôtel de Soissons near les Halles. It eventually relocated in October 1720 in the rear garden of Hôtel Tubeuf, which by that time was part of the headquarters complex of Law's Company that also included the Hôtel de Nevers. The market remained on that location until 27 June 1793 when it suspended operations in the chaotic context of the French Revolution. The building later became part of the Bibliothèque nationale de France, which had first been located in the Hôtel de Nevers in the 1720s.

The market reopened on 10 May 1795 in the Louvre Palace, in Anne of Austria's former summer apartment on the ground floor of the Petite Galerie,[8]: 73  and stayed there until 9 September 1795.[9] In September 1795, the Bourse again closed for a few months; it reopened in January 1796 in the church of Notre-Dame-des-Victoires, then in October 1807, moved to the Palais-Royal, and finally, in March 1818, to the former Couvent des Filles-Saint-Thomas [fr].

By then, a permanent home for the stock exchange was under construction on an adjacent site, soon known as the Palais Brongniart for its architect Alexandre-Théodore Brongniart who died before the building was completed. Brongniart had submitted his project, which was a rectangular neoclassical Roman temple with a giant Corinthian colonnade enclosing a vaulted and arcaded central chamber. His designs were endorsed by Napoleon and won Brongniart that major public commission at the end of his career. After his death in 1813, the building was completed by Éloi Labarre from 1813 to 1826.[10] On 6 November 1826, the stock exchange finally moved into the Palais Brongniart,[9]: 118-119  which was and remains owned by the City of Paris. From 1901 to 1905, Jean-Baptiste-Frederic Cavel designed the addition of two lateral wings, resulting in a cruciform plan with innumerable columns. According to the architectural historian Andrew Ayers, these alterations "did nothing to improve the reputation of this uninspiring monument."[10] After Euronext stopped using the building, it was repurposed by the City of Paris as an events venue.

Following the 1988 reform, the Compagnie des agents de change, renamed SBF, left its iconic art deco seat at 4, place de la Bourse to move to the former Paris office of Société Centrale des Banques de Province then Chase Manhattan Bank at 39, rue Cambon.[11] That building remained the seat of SBF, then Euronext Paris until the latter moved to La Défense in 2015. The building on rue Cambon was subsequently restructured to house offices of Chanel.[12]

Operations

[edit]

It operates the MATIF futures exchange, which trades futures and options on interest rate products and commodities, and MONEP, equity and index futures and options. All products are traded electronically on the NSC system adopted by all of the Euronext members. Transactions are cleared through LCH.Clearnet. Cash settlement is T+2.[13] Trading hours are 9 am to 5:30 pm CET, Monday to Friday.

Structure and indices

[edit]

The French equities market is divided into three sections. The Premier Marché, formerly called the Official List, includes large French and foreign companies, and most Bond issues. The Second Marché, lists medium-sized companies, while nouveau marché lists fast-growing start up companies seeking capital to finance expansion, linked to Euro.nm, the European equity growth market. A third market, Marché Libre, is nonregulated, administered by Euronext Paris for transactions in securities not listed on the other three markets.

Euronext Paris calculates a family of indices. The CAC 40 is the exchange's benchmark, disseminated in real time. Its components are included in the broader SBF 120 Index, a benchmark for investment funds. The SBF 250 index, a benchmark for the long-term performance of equity portfolios, includes all of the SBF 120; it is structured by sector. The MIDCAC index includes 100 of the most liquid medium-size stocks on the Premier Marché and Nouveau Marché calculated on the basis of opening and closing prices, while the Second Marché index focuses on that market. Both indices are benchmarks for funds. The Nouveau Marché Index represents stocks in the growth market. The SBF-FCI index is based on a selection of convertible bonds that represent at least 70% of the total capitalization of this market, calculated twice daily. For derivatives, MONEP trades short-term and long-term stock options and futures and options on a family of Dow Jones indices. Euronext Commodities products include commodity future and options on European rapeseed and futures on rapeseed meal, European rapeseed oil, milling wheat, corn, wood pellets, dairy and Paris Real Estate.

Key figures

[edit]

For the fiscal year ending December 2004, Euronext Paris recorded sales of US$522 million, a −12.9% decrease in sales from 2003.

Euronext Paris has a US$2.9 trillion total market capitalization of listed companies and average daily trading value of its combined markets of approximately US$102 billion/€77 billion (as of 28 February 2007).

History

Origins and Early Development

The Paris stock exchange, known as the Bourse de Paris, traces its origins to the early amid the financial experiments of Scottish economist John Law. Between 1717 and 1720, Law's Mississippi Company, which held a monopoly on trade with , sparked intense speculative trading in its shares, primarily conducted informally in the narrow Rue Quincampoix in central . This chaotic open-air market, often marked by frenzied crowds and fraud, highlighted the need for a regulated venue following the scheme's collapse in 1720, which devalued the company's stock and eroded public confidence in financial instruments. To restore order, King issued a royal decree (arrêt du conseil) on September 24, 1724, formally establishing the Bourse de Paris as an official marketplace for trading government securities and shares. Initially housed in temporary locations such as the Hôtel de Nevers and the near the , the exchange operated under a guild-like structure of appointed brokers (agents de change) who held monopolistic rights. By the late 18th century, amid the , it relocated several times, including to the deconsecrated church of the Petits Pères and back to the , reflecting the instability of the period. In 1808, Napoleon Bonaparte initiated construction of a permanent home at the Palais Brongniart, designed by architect Alexandre-Théodore Brongniart on the site of a former , to centralize and dignify trading activities; the neoclassical building opened in 1826 and served as the exchange's headquarters until 2015. During the , physical trading evolved into an open-outcry system where brokers gathered around a central pit in the Salle des Pas-Perdus to execute continuous auctions, standardizing orders and clauses for securities like rentes (government bonds) and shares. Regulatory frameworks advanced under Napoleonic law, with the 1807 Code de commerce providing the first comprehensive rules for exchange operations, including broker licensing and , while a ban on forward contracts persisted until legalization in 1885, spurring innovations in securities law. Subsequent reforms, such as the 1890 decree on trading procedures and the 1898 transparency measures, reduced risks and costs, enabling the Bourse to handle growing volumes—reaching multiples of France's GDP by the early —through enhanced broker oversight and official price listings. A notable early incident underscoring the exchange's vulnerabilities occurred on March 5, 1886, when anarchist Charles Gallo hurled a bottle of into the trading floor from the gallery and fired three shots, injuring several brokers while shouting "Vive l'anarchie!" Motivated by anti-capitalist , Gallo's attack, for which he was convicted and sentenced to penal servitude in , amplified fears of anarchist violence in and prompted immediate reinforcements in policing around public financial institutions, including stricter access controls at the Bourse. This event, part of a broader wave of attacks, contributed to evolving security protocols that emphasized to protect the physical trading environment into the early 20th century.

Modernization and Key Mergers

The modernization of the Paris Bourse began in the mid-1980s with the introduction of systems to replace traditional methods. In 1986, the exchange launched the Cotation Assistée en Continu (CAC) system, a computerized platform that enabled continuous assisted trading and progressively extended to more , allowing for all-day electronic order matching. By 1989, the system achieved full of quotations, marking the Paris Bourse as one of the first major exchanges to transition entirely to screen-based trading. This shift enhanced efficiency and accessibility, setting the stage for further technological advancements, including the adoption of the Nouveau Système de Cotation (NSC) platform in , which provided improved trading capabilities and real-time market data integration. A pivotal step in the Bourse's evolution occurred on September 22, 2000, when it merged with the Stock Exchange and the to form N.V., creating the first pan-European integrated exchange. This merger centralized trading operations across the three markets, leveraging the NSC platform for unified cash market integration by 2003, and expanded the group's reach to over 1,300 listed companies while fostering cross-border liquidity. Following the formation of , the group pursued further growth through acquisitions, including the Stock Exchange in 2002 and the London International Financial Futures and Options Exchange (LIFFE) later that year, broadening its geographic and product scope. Subsequent corporate integrations further globalized the entity. In April 2007, Euronext merged with NYSE Group in a $14 billion deal, forming and establishing the world's largest transatlantic exchange operator, which combined European and U.S. markets for enhanced international trading volumes. Following Intercontinental Exchange's () acquisition of in November 2013, Euronext was spun off through an in June 2014, regaining its independence as Euronext N.V. and refocusing on European operations with a exceeding €3 trillion at the time. In June 2015, Euronext Paris relocated its headquarters to the building in , Europe's largest business district, symbolizing its commitment to operational efficiency and strategic positioning within a hub of financial institutions. This move facilitated closer collaboration with major banks and corporations, streamlined internal processes, and reinforced Euronext's role as a key financier of the European economy by centralizing activities in a modern, integrated environment.

Operations

Trading Processes and Hours

Euronext Paris conducts trading sessions from 9:00 a.m. to 5:30 p.m. (CET), Monday through Friday, excluding public holidays. The session is divided into distinct phases to facilitate orderly and execution: a pre-opening call for order accumulation starting at 7:15 a.m., followed by the opening uncrossing at 9:00 a.m., continuous trading during the main session, a pre-closing call beginning at 5:25 p.m., and the closing uncrossing from 5:30 p.m. to 5:35 p.m. A post-closing trading-at-last phase may extend briefly afterward, allowing trades at the closing price for liquid securities. All trading occurs electronically on Euronext's Optiq platform, which handles order matching for cash equities through a single across its markets. In the continuous trading phase, applicable to most liquid stocks such as those in the index, buy and sell orders are matched automatically based on price-time priority, where the best-priced orders execute first, and among equal prices, the earliest entered order prevails. Supported order types include limit orders, which specify a maximum purchase price or minimum sale price, and market orders, which execute immediately at the best available price without a price limit. During auction phases, price formation follows rules designed to maximize executable volume while staying closest to a reference price, typically the previous day's closing price; unmatched orders carry over to the next phase if valid. For derivatives, Euronext Paris integrates futures and options trading via its pan-European markets, historically operated through the MATIF (for futures) and MONEP (for options) platforms, now unified under Optiq with extended hours varying by contract—often from 8:00 a.m. to 6:00 p.m. CET or later for specific products like futures. These markets support similar order matching mechanisms, enabling hedging and on underlying equities, indices, and commodities traded on the exchange.

Clearing and Settlement

Clearing for equity trades on Euronext Paris is handled by Euronext Clearing, Euronext's in-house multi-asset central counterparty (CCP), following the migration from LCH SA in November 2023; this CCP now serves as the default clearer for cash equities across Euronext's Amsterdam, Brussels, Lisbon, and Paris markets. For derivatives and commodities, clearing is also provided by Euronext Clearing, following the migration of these products from LCH SA in Q3 2024. As a CCP, Euronext Clearing interposes itself between buyers and sellers, becoming the buyer to every seller and the seller to every buyer, thereby guaranteeing trade settlement and mitigating counterparty risk. Settlement of securities transactions on Euronext Paris follows a T+2 cycle, meaning final delivery versus payment (DvP) occurs two business days after the trade date, ensuring simultaneous exchange of securities and cash to minimize settlement risk. This process is facilitated through Euroclear France, the central securities depository (CSD) for French securities, which handles custody, asset servicing, and DvP settlement in central bank money via the TARGET2-Securities (T2S) platform. Euronext maintains integration with Euroclear France for seamless post-trade operations, including collateral management enhancements announced in February 2025 to support repo clearing and liquidity efficiency. Note that from September 2026, Euronext Securities will become the default CSD for equity settlements in Paris, Amsterdam, and Brussels, potentially streamlining further integration. Risk mitigation in clearing involves rigorous margin requirements calculated daily using value-at-risk (VaR) models tailored to asset classes, with intraday margins called as needed to cover potential losses. Euronext Clearing holds €25.1 billion in combined margins and default fund resources (as of 2024), providing a multi-layer waterfall for loss absorption in case of member default. Default management procedures include early warning indicators, position close-out auctions, and hedging strategies to contain losses, ensuring the stability of the post-trade ecosystem. These mechanisms, compliant with EMIR regulations, underscore the CCP's role in fostering secure and efficient transaction finalization on Euronext Paris.

Market Segments

Euronext Paris organizes its listings into distinct market segments tailored to companies at different stages of development, each with specific eligibility criteria designed to balance accessibility with investor protection and market integrity. The primary segments include the for established large-cap firms, for high-potential small and medium-sized enterprises (SMEs), and for early-stage or smaller unlisted companies seeking initial visibility and financing. These segments collectively host over 800 companies as of 2025, spanning diverse sectors such as , , and consumer goods, with significant representation from international issuers. The Euronext Regulated Market, formerly known as the Premier Marché, serves as the flagship segment for mature companies aiming to attract institutional and global investors through high liquidity and stringent oversight.

Indices and Benchmarks

Major Indices

The serves as the flagship benchmark index for Euronext Paris, tracking the performance of the 40 largest companies listed on the exchange by free-float adjusted and , as measured by average daily trading turnover. It provides a broad representation of the French equity market and acts as a primary indicator of economic health in , influencing investor sentiment and serving as the basis for numerous financial products including futures, options, and exchange-traded funds. Launched on December 31, 1987, with a base value of 1,000 points, the index replaced earlier benchmarks and has since become a cornerstone for assessing the performance of major French corporations across sectors like , , and . Complementing the , the broader CAC family of indices covers various market capitalizations and themes to offer a comprehensive view of the . The includes the 20 companies immediately following the in rankings, focusing on established mid-cap firms with significant growth potential. The CAC Mid 60 encompasses the next 60 mid-sized companies eligible after the CAC Large 60 (which combines the and ), providing exposure to a diverse set of medium-capitalization stocks. For smaller enterprises, the CAC Small index tracks liquid small-cap companies outside the SBF 120 universe, emphasizing those meeting minimum free-float velocity thresholds to ensure tradability. Additionally, the ESG represents a sector-specific variant, selecting at least 35 companies from the investable universe based on strong environmental, social, and governance (ESG) performance while excluding those involved in controversial activities like or fossil fuels. All major CAC indices follow consistent composition rules to maintain relevance and . Selection prioritizes free-float adjusted combined with liquidity criteria, such as average daily turnover and free-float velocity (requiring at least 20% annual or 30% quarterly trading of free-float shares for inclusion in smaller indices). Weighting is applied on a free-float basis, with individual constituent caps at 15% for standard indices and 10% for the CAC 40 ESG to prevent over-concentration. Reviews occur quarterly in March, June, , and December, with a full annual reassessment in to adjust for changes in market conditions, using buffer zones to minimize turnover among borderline candidates. This methodology ensures the indices reflect dynamic market leadership while upholding stability for investors.

Index Calculation and Maintenance

Euronext Paris indices, including the flagship , are calculated on a real-time basis using a free-float weighting methodology. This approach determines each constituent's weight by multiplying the number of shares in free float—shares available for public trading, excluding those held by controlling shareholders or locked-up holdings—by the current share price, adjusted for any capping factors to prevent over-concentration. The aggregate free-float of all constituents is then divided by a that ensures continuity from the index's base value, providing a dynamic reflection of market movements throughout the trading day. Updates to index levels occur intra-day every 15 seconds during trading hours, enabling timely dissemination for investors and market participants. The maintenance of these indices involves periodic reviews to ensure representativeness and relevance. For the CAC 40, reviews are conducted quarterly in March, June, September, and December, with a comprehensive annual review in September that includes detailed assessments of eligibility and rankings. Constituents are selected and ranked based on free-float market capitalization and average daily trading volume over a specified reference period, typically the prior six months; the top 40 eligible companies form the index, with changes such as additions or removals implemented on the first trading day of the following month. Smaller indices within the Euronext Paris suite, such as sector-specific or mid-cap benchmarks, follow a similar quarterly review cadence, though some may have annual adjustments depending on their rulebooks, focusing on liquidity thresholds and market representation criteria. These processes are overseen by an independent Index Steering Committee to maintain transparency and objectivity. To preserve index continuity amid corporate events, adjustments are applied systematically for actions such as dividends, splits, and mergers. Ordinary dividends are reinvested in total return variants without altering the level, while special dividends prompt a reduction in the affected share's price and a corresponding adjustment on the ex-date. splits or reverse splits lead to proportional changes in the number of , with the recalibrated to avoid artificial index shifts. In cases of mergers or acquisitions, constituents may be removed if control exceeds 85% post-event or replaced via share-for-share ratios if the successor meets eligibility; free-float factors are updated accordingly to reflect new ownership structures. These adjustments, detailed in 's corporate actions policy, ensure the index accurately tracks the underlying market without disruptions. Euronext Indices, a dedicated of N.V., handles the calculation, publication, and licensing of these benchmarks. It licenses indices like the for use in contracts, exchange-traded funds (ETFs), and other products, supporting over 15,000 linked financial instruments globally and facilitating for asset managers. This licensing framework ensures compliance with regulatory standards such as the EU Benchmarks Regulation, promoting widespread adoption in portfolio construction and .

Trading Volumes and Financial Performance

The Euronext Group, with as its largest market, has demonstrated robust trading activity in recent years, with average daily cash trading volumes reaching €11.0 billion in the third quarter of 2025, marking a 14.8% increase year-over-year. Paris-specific average daily volumes were €4.1 billion in cash equities as of June 2024, reflecting sustained investor interest amid broader European economic recovery and surpassing pre-2020 levels where average daily volumes hovered around €7-8 billion in 2019. The financial performance of Euronext Paris operations contributes significantly to the group's overall revenue, with H1 2025 revenue attributable to France (encompassing Paris activities) at approximately €191 million, representing about 21.6% of Euronext's total revenue of €885 million during that period; full-year estimates suggest ~€380 million. Key performance indicators include a revenue capture rate of 0.53 basis points on cash trades in Q3 2025, which supported an 11.5% rise in cash equity trading and clearing revenue to €82.5 million for the group, with Paris as the dominant contributor. Market volatility events from 2022 to 2025, including geopolitical tensions and inflationary pressures, have influenced trading volumes on Euronext Paris, often boosting activity during peaks but leading to moderation in calmer periods. For instance, in Q3 2025, lower volatility contributed to a decline in related derivatives trading, though cash equity volumes remained resilient. Overall, these dynamics have enhanced revenue stability through diversified fee structures, with non-volume-related income comprising around 60% of total revenue in recent quarters.

Recent Developments

Technological and Regulatory Updates

Euronext has integrated AI-driven tools into its market surveillance operations to enhance monitoring of trading activities, detect potential , and ensure across its platforms. These tools leverage algorithms to analyze vast datasets in real-time, improving the efficiency and accuracy of oversight in high-volume equity and markets. This adoption aligns with broader European efforts to incorporate for proactive in financial infrastructure. Euronext has continued to upgrade its core trading infrastructure through the Optiq platform, which supports faster execution speeds and scalability for diverse . In March 2024, the Italian derivatives markets, including those relevant to Paris listings, fully migrated to Optiq, enabling sub-millisecond latency and handling increased trading volumes without disruption. Further enhancements in 2025 extended Optiq to new power futures markets, facilitating unified access and reduced operational latency for cross-border transactions. To support emerging digital assets, Euronext expanded its clearing services in March 2025 to include cryptocurrency exchange-traded products (ETPs), allowing tokenized representations of digital assets to be traded and cleared within its regulated ecosystem, with over 150 such ETPs listed by early 2025. On the regulatory front, implemented the EU Digital Operational Resilience Act (DORA), which became fully applicable on January 17, 2025, to strengthen ICT risk management and operational continuity. The exchange established a dedicated governance program involving senior executives and cross-functional teams from risk, IT, and legal departments to align with DORA's requirements for resilience testing, third-party oversight, and incident reporting. This framework particularly bolsters cybersecurity measures by mandating advanced threat intelligence and response protocols to mitigate digital disruptions, integrating seamlessly with 's existing information security controls certified under ISO/IEC 27001:2022. In parallel, Euronext has enhanced ESG reporting in compliance with the Sustainable Finance Disclosure Regulation (SFDR), promoting greater transparency for sustainable investments. The 2025 ESG Trends Report, based on verified data from over 1,550 listed companies, demonstrates rising adoption of SFDR-aligned disclosures, with significant improvements in emissions and reporting rates exceeding 70% for key metrics. To facilitate this, Euronext released an ESG Reporting Guide in September 2025, offering standardized templates and verification tools via its Connect portal to help issuers meet SFDR principal adverse impact (PAI) indicators and investor demands. Euronext has also integrated sustainable finance tools to support ESG integration, launching an ESG Advisory Service in September 2024 for small and medium-sized enterprises (SMEs) to comply with European Sustainability Reporting Standards (ESRS). This service, combined with a new ESG benchmarking tool, enables real-time assessment of sustainability performance against peers, fostering adoption of SFDR-compliant strategies and accelerating the flow of capital toward green initiatives across Paris-listed entities.

Strategic Expansions and Milestones

In 2025, marked its 25th anniversary, reflecting on a quarter-century of shaping European capital markets through consolidation and . Since 2021, the exchange has welcomed over 400 new company listings across its markets, including more than 200 firms and 80 international issuers, underscoring its expanding role as a gateway for tech and biotech sectors. This surge highlights 's strategic focus on fostering growth in high-potential industries, with initiatives like the Tech Leaders segment adding dozens of innovative companies annually to promote visibility and liquidity for emerging tech leaders. Euronext has pursued key acquisitions to bolster its service ecosystem. In March 2025, it announced the acquisition of Admincontrol, a Norwegian SaaS provider specializing in digital governance and secure collaboration tools, from Visma for €398 million; the deal was completed in May 2025, enhancing Euronext's post-trade and compliance offerings for listed companies. Earlier efforts included a voluntary share exchange offer for all shares of Hellenic Exchanges - Athens Stock Exchange (ATHEX), launched in October 2025 following regulatory approval, with the acceptance period running from October 6 to November 17, 2025. On November 10, 2025, a revision to the offer was approved, lowering the acceptance threshold to 50% plus one share, and on November 14, 2025, the Hellenic Capital Market Commission granted further regulatory approvals, aiming to integrate the Greek market into Euronext's pan-European platform and expand its geographic footprint in Southeastern Europe. The exchange has driven growth in international listings, attracting issuers from beyond the to leverage its unified trading infrastructure. This expansion supports broader capital markets integration, as evidenced by Euronext's advocacy for reforms like the European Common Prospectus, launched in April 2025 to streamline IPO processes and reduce cross-border barriers, potentially unlocking €13 trillion in savings for investment across the union. Significant milestones include Euronext N.V.'s inclusion in the CAC 40 index, effective September 22, 2025, replacing Teleperformance and signaling the group's transformation since its 2014 IPO through sustained revenue growth and market consolidation. Complementing this, Euronext launched Euronext ETF Europe in September 2025, the first fully integrated pan-European marketplace for ETFs and ETPs, unifying listing, trading, clearing, and settlement to combat market fragmentation and accelerate product growth across its venues.
