Betting on the ATP Finals in Turin: round robin, indoor hard courts and the 2026 field

The round robin and the third-round problem

Each group has four players and each player meets the other three. The top two go through: the Group A winner plays the Group B runner-up in one semi-final, and the Group B winner plays the Group A runner-up in the other. Every singles match, the final included, is best of three tie-break sets.

The tiebreak order in a group is fixed by the rules. Wins come first, then matches played, then the head-to-head result if two players are level. A three-way tie goes to sets percentage, then games percentage, and only then to the rankings. The “matches played” step exists because players do withdraw during the week and alternates come in.

This is where the third round needs care. By then each player's position falls into one of a few states, and each one prices differently:

• Already through with a game to spare. Two wins from two does not always settle it, because three players can finish 2–1 and the place then goes on sets percentage. Where the maths has closed, though, a player may manage his body for the semi-final.
• Needs a win, or a win in straight sets. Here the percentage rules matter. A player who must win without dropping a set is a different bet from one who only needs a win, and set handicaps carry that information.
• Out at 0–2. He can only go through in a three-way tie on 1–2, decided on percentages. Some players in this spot compete hard for the 200 ranking points a group win carries; others look like they want the week over.

Our view: in the final group round we put more weight on the standings than on the head-to-head record. When the two last-round matches in a group are played one after the other, the result of the first can change what a player needs in the second, so we would check the ATP Finals odds again between them.

What the 2025 edition and the indoor court tell a bettor

Sinner has won the last two editions without losing a set. In 2024 he beat Taylor Fritz 6–4 6–4 in the final; in 2025 he beat Alcaraz 7–6(4) 7–5 on 16 November. That second title took his run of indoor match wins to 31, according to the ATP's report of the final.

An indoor hard court suits players who serve big and take the ball early. Conditions are the same every session, which takes away one of the variables that unsettles prices at outdoor events. Two things follow for ATP Finals odds on single matches.

Total games. With three-set matches and tie-break sets, a total-games line usually sits in a narrow band. The swing comes from tiebreaks and from whether the match goes to a third set. Between two strong servers we look at the over; where one player is far stronger on return, the under deserves more attention.

Set handicaps. At this level every opponent is a top-ten-calibre player. A -1.5 sets handicap on a favourite is a bet that he wins in straight sets against one of the best eight players of the season, and the price should reflect that.

The money is also worth knowing. In 2025 a round-robin win was worth 200 ranking points, a semi-final win 400 and the final 500, with 1,500 for an unbeaten champion; the unbeaten champion's prize money was $4,881,100. Those numbers explain why a player who is already out still has something to play for.

Outright, group markets and our picks

Everything below is our opinion, labelled as such. The groups have not been drawn, and we do not quote any sportsbook's prices. If you want to turn a price into a percentage before betting, use the odds calculator.

The draw rules shape the outright. The top seed goes into Group A and the second seed into Group B, so Zverev and Jannik Sinner cannot meet before the semi-finals. Seeds three to eight are paired and drawn alternately, so Alcaraz will land in a group with one of the two.

Outright. Our view: Alexander Zverev has had the best season by points. He won the French Open and the US Open, and lost the Wimbledon final to Sinner. Sinner is the defending champion with ten straight wins in Turin, but he did not play the US Open and has entered only nine Race events, so we would want to see him play the autumn indoor events before backing him short. Our pick for now is Sinner, with Zverev as the better value if his price stays close. We would expect the ATP Finals odds to put these two clear of the field all autumn.

Carlos Alcaraz. Our view: he won the Australian Open, then lost to Shelton in the US Open quarter-finals. He was runner-up in Turin last year. Carlos Alcaraz becomes more interesting once the draw shows which of the top two he faces in the group.

Group markets. Our view: the usual options are the group winner, to reach the semi-finals and the finishing order. Group betting rewards patience: wait for the draw, then look for the third and fourth seeds in each group, because two players from each four go through. Ben Shelton, the US Open finalist, is the name we would watch from the chasing pack.

Total games. Our view: we prefer totals to handicaps in the group stage, because the third-round motivation problem hits handicaps harder.

Where to watch the ATP Finals

Who shows the season finale depends on your country: national broadcasters hold the television rights, and the ATP's own platforms carry live scores, draws and the order of play. Check the listings close to the event.

A few betting sites put some tennis on a video player inside your account once you are logged in. We picked sites where that option exists, but whether the ATP Finals are included, and in which countries, is different on every site. Look before the first session rather than at the start of a match.

More tennis betting

The rules that apply to every tennis bet, such as what happens to a bet after a retirement, are on our tennis betting guide. Novak Djokovic has his own profile, though he was not in the top twelve of the Race at the end of September.

We will update this page after the Paris Masters fixes the field and again after the group draw. Until then, treat all ATP Finals odds as a guide to the order of the field rather than a final word.
