ATP Masters 1000 tournaments

The ATP 1000 series was introduced in 1990 with the inception of the ATP Tour by bringing together the nine most prestigious tournaments of the Grand Prix Super Series of the preceding ITF Grand Prix Circuit. Results in ATP 1000 events earn players more ranking points than regular tournaments but less than Grand Slam events or the year-end ATP Finals. Up until 2007, most ATP Masters 1000 finals were contested as best-of-five-set matches, but from 2008 all events were decided in best-of-three-set matches. As part of a shake-up of the tennis circuit in 2009, the Masters Series became the ATP 1000 or ATP Masters 1000 (both terms used by the ATP^[7]), with the addition of the number 1000 referring to the number of ranking points earned by the winner of each tournament. Contrary to earlier plans, the number of tournaments was not reduced from nine to eight and the Monte-Carlo Masters remained part of the series although, unlike the other events, it does not have a mandatory player commitment. The Hamburg Masters event was downgraded to an ATP Tour 500 event. The Madrid Open moved to May and onto clay courts. A new tournament in Shanghai replaced the Hamburg Masters and took over Madrid's former October indoor slot. In 2011, six of the nine 1000 level tournaments were combined ATP and WTA events.

• 1990–1995: ATP Championship Series, Single Week
• 1996–1999: ATP Super 9
• 2000–2003: Tennis Masters Series
• 2004–2008: ATP Masters Series
• 2009–2018: ATP World Tour Masters 1000
• 2019–present: ATP (Masters) 1000

The following ranking points are as of 2025.^[8]

Currently, the following nine tournaments are part of the ATP Masters 1000: Canadian Open (alternating yearly between Montreal and Toronto), Italian Open (held in Rome), Indian Wells Open, Miami Open, Monte-Carlo Masters, Madrid Open, Cincinnati Open, Shanghai Masters and Paris Masters.^[10] Since 2009, five of the tournaments have been held on outdoor hard courts, three on clay and one on indoor hard court, whereas from 1990 until 2008 there were two indoor tournaments at the top-9 level. In 2009, the Shanghai Masters replaced the Madrid Open, which was until then held as an indoor event, in the eighth slot of the year with the Madrid Open switched to clay courts, replacing the Hamburg Open in the spring clay court season. The Shanghai Masters was designated as an outdoor event despite the facility having a retractable roof and having been used as the indoor venue for the ATP Finals from 2005 until 2008. Other than Hamburg, the tournaments defunct between 1990 and 2009 were Stockholm (1990–1994) and Stuttgart (1995–2001), which were held as indoor events in the eighth slot.

On October 23, 2025, the ATP announced that a new Masters 1000 tournament (the tenth on the calendar) will be held in Saudi Arabia, likely beginning in 2028, although the specific date remains to be determined. The placement of the event on the ATP calendar has also not been announced. The field will be 56 players and the event will be non-mandatory. This will be the first time the ATP Masters 1000 events number ten in one calendar year.^[11]
