While lightweight and welterweight have established title lineages, the heavyweight division (over 220 lb / 100 kg) remains without a formal championship as of 2025, featuring instead a series of high-profile non-title bouts that trace ONE's grappling origins. Garry Tonon emerged as an early standout, winning his promotional debut via first-round armbar against Shinya Aoki on May 26, 2017, at ONE: Heroes of the Earth, in a heavyweight grappling superfight that drew significant attention to the format. Tonon continued his success with victories in 2022, including a decision over fellow BJJ black belt Tye Ruotolo at ONE 157 on May 20 and a submission of Matheus Diniz earlier that year, showcasing his wrestling integration and kneebar proficiency in ADCC-style matches.

However, she lost the championship to by unanimous decision on August 2, 2024, at ONE Fight Night 24, ending her reign after two defenses. Bastos retained the title in a rematch against Kelly on December 6, 2024, at ONE 171, again winning by unanimous decision in a closely contested bout. As of November 2025, Bastos remains the reigning champion, with Kelly having been released from her ONE contract in July 2025 following a series of high-stakes challenges. In the strawweight submission grappling category, no formal world title has been established as of 2025, but the division has seen notable activity through competitive challenges featuring top athletes like Danielle Kelly from 2023 to 2025. Kelly, who primarily competed in , took on strawweight-level opponents in exhibition and tournament-style matches during this period, contributing to the division's emerging competitive landscape and pushing for greater recognition of women's across weight classes. Her efforts in these bouts, including dominant performances against international contenders, underscored the potential for expanded strawweight opportunities within ONE's programming.
