Grand Slams are the big news, but they’re only four weeks in a tennis calendar that stretches almost all year. Below the majors is a tier of tournaments with real championship gravitas all their own, with virtually every top player in the world and enough ranking points to change a season on their own. These are the ATP Masters 1000 and WTA 1000 events, and understanding how they work really adds depth to following tennis outside of the four biggest weeks on the calendar.
“At Sportsarcane, This guide explains what these tournaments are, how they work and why 2026 has already seen some very dominant performances at this level.
What Makes a Tournament a “Masters 1000” or “WTA 1000” Event
The ATP Masters 1000 series comprises nine tournaments in the annual tennis calendar, each named after the 1,000 ranking points awarded to each singles champion (the most points available outside of the four Grand Slams). The 2026 calendar will stretch from March through November and will feature Indian Wells, Miami, Monte-Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai and the Paris Masters, with total prize money at several of these events now nearing $9.4 million.
The WTA has a similar format in its own WTA 1000 tier, which will expand to 10 events in 2026 and run from February through October. The women’s calendar includes Doha, Dubai, Indian Wells, Miami, Madrid, Rome, Canada, Cincinnati and other stops, all of which are mandatory events where top-ranked players are expected to enter barring injury or a legitimate scheduling conflict.
Some of these tournaments are shared joint events, like Indian Wells, Miami, Madrid and Rome, where the ATP and WTA tours play at the same venue during the same run of dates. These joint events have become some of the most popular stops on the calendar, giving fans a chance to see both the men’s and women’s game at its highest non-Slam level in one visit to the tournament grounds.
How the Draw and Format Differ From Grand Slams
Most Masters 1000 and WTA 1000 events have a 96-player singles draw, smaller than the 128-player field of a Grand Slam but still much larger than the standard 500 or 250-level tournaments found elsewhere on the calendar. Some Masters tournaments like Monte-Carlo and the Paris Masters opt for a more compact 56-player field, reflecting their placement later or earlier in notably busy parts of the calendar.
The format of the match is also very different to the majors. At this level , both men and women matches are best-of-three sets , rather than the best-of-five format used in men ‘s Grand Slam matches . The shorter match time tends to produce more compressed , higher-intensity tennis . The very best players now get an extra day of rest between the early rounds at a few of the bigger Masters events over the last few years thanks to a move to a 12-day format, compared to the tighter scheduling they used to have.
Why These Tournaments Matter So Much for the Rankings
A Masters 1000 or WTA 1000 title is the single biggest point swing on offer outside of a Grand Slam, which is why these events carry so much strategic weight throughout the season. A player targeting the world’s No. 1 position can make huge leaps with a good run at the Masters events, and since many of those are mandatory for the top-ranked players, missing one without a good reason can result in ranking point penalties that make it much harder to climb back up the rankings.
This year’s Miami Open was a perfect example of how much a single title at this level can change a career. A title at this level can be a career-changing swing, and Jakub Mensik’s first Masters 1000 trophy instantly placed him in the conversation for the sport’s next generation of contenders. The Czech beat Novak Djokovic in the final.
Jannik Sinner’s Dominant 2026 Masters Campaign
No storyline at this level has been more dominant in 2026 than Jannik Sinner’s run through the Masters 1000 circuit. Sinner has already made five finals at the Masters level this season, converting a couple of those into titles, including a hard-fought victory over Daniil Medvedev at Indian Wells, which took two tiebreaks to finish off.
That kind of consistent brilliance at the Masters level has been directly responsible for Sinner’s commanding lead at the top of the ATP rankings this season. Masters titles are counted as part of a player’s 19 best results, so a player who can win regularly at this level – and not just at the Grand Slams – will generally have a much larger and more comfortable cushion at the top of the rankings than a player who only wins major titles.
Notable WTA 1000 Storylines This Season
The women’s 1000-level circuit has produced its own storylines in 2026, with Aryna Sabalenka’s continued success at this level reinforcing her hold on the world No. 1 ranking even through a season that has seen real pressure from Elena Rybakina and other top contenders. Coco Gauff, Sabalenka and Elina Svitolina have all been in more than one WTA 1000 final this year and it shows how competitive the tier below the Grand Slams has got on the women’s side.
The implications of these findings go beyond the titles themselves. The reason some players turn up at Grand Slams with so much more momentum than their reputation might suggest is partly down to deep runs at WTA 1000 events throughout the season. Consistent performance at this level can be the best real-time indicator of a player’s current form ahead of the sport’s biggest events.
Why Fans and Bettors Should Pay Attention Beyond the Majors
Paying close attention to the Masters 1000 and WTA 1000 circuit has real value for anyone hoping to get ahead of storylines before they become obvious at the next Grand Slam. A player quietly building momentum through a strong summer hard-court Masters run often enters the US Open as a far more dangerous threat than their seeding alone would suggest, and that kind of context simply isn’t visible to fans who only tune in for the four majors each year.
The competition at this level has also gotten much deeper in recent years, with almost every top-20 player in the world being forced to play in the majority of these mandatory events. That consistency is a much better measure of true form than Grand Slam results in isolation, especially as a Masters or WTA 1000 draw typically has a stronger overall field, round to round, than all but the very latter stages of a major.
