The US Open has been one of the less predictable men's Grand Slam tournaments, with each of the last five editions having been won by different players.
And as the ATP Tour moves on from the grass-court swing to the hard-court season, there are plenty of players in contention for the final major title of the year.
(Odds will display when markets are available)
After winning both the French Open and Wimbledon already this season, Carlos Alcaraz is unsurprisingly market leader at 11/8.
Alcaraz impressed with a 6-2 6-2 7-6 demolition of Novak Djokovic in the men's Wimbledon final this season but it was at the US Open that he won his maiden Grand Slam title in 2022.
He was again not far off it in his title defence last year, reaching the semi-finals, and the Spaniard is expected to be in the mix to claim a fifth Grand Slam of his career.
Veteran Djokovic deserves credit for having gone from knee surgery in June to the final of the Wimbledon men's singles tournament in July but there is no getting away from the fact it has been a tough season for the Serbian.
Having typically dominated the Australian Open in years gone by, Djokovic could only reach the last four in Melbourne before he had to withdraw from the French Open in the quarter-finals.
He rediscovered some form at Wimbledon but was handed a pretty soft draw at the All England Club and some punters may be cautious of backing him at 15/8.
Before Alcaraz won back-to-back Grand Slam titles, Jannik Sinner was the player everyone was talking about on the ATP Tour this year.
The Italian exited Wimbledon at the quarter-final stage but had won 42 of his 46 matches on tour following the season's third Grand Slam.
He has won four titles this campaign, including his first Grand Slam at the Australian Open, and he will be eager to make a mark in the next hard-court major in New York.
The US Open is the Grand Slam in which Daniil Medvedev has sought the most success in his career and he is again considered a danger at 5/1.
Medvedev was a finalist and semi-finalist in 2019 and 2020 before he finally came out on top in New York in 2021.
He has also reached the final of each of the last two hard-court Grand Slams - the 2023 US Open and 2024 Australian Open - and looks a serious competitor.
A first Grand Slam title still eludes Alexander Zverev but he has come closer this year, making the semi-finals of the Australian Open and the final of the French Open.
A finalist at Flushing Meadows in 2020, the German has made at least the quarter-final stage of the US Open in each of the last three tournaments in which he has competed.
He is a versatile talent who has played some of the best tennis of his career this year.
Rafael Nadal has not made it beyond the second round of a Grand Slam event since the US Open in 2022 and he has already missed two of the three majors this season.
But he has won four US Open titles in his career - the last coming in 2019 - and can never be discounted if involved. He is a 20/1 shot.
It was an underwhelming Wimbledon for Stefanos Tsitsipas, who was dumped out in the second round by the unseeded Emil Ruusuvuori, and that summed up the Greek's season.
He reached the fourth round of the Australian Open before a quarter-final appearance at the French Open and has just the one title to his name in 2024.
For that reason, he is out at 33/1 to win the US Open.
Casper Ruud was a surprise finalist at the US Open in 2022, but that seems as though it was an anomaly rather than the start of something as he has only made it beyond the second round at Flushing Meadows one other time.
Also a 33/1 shot, it would be a surprise to see the Norwegian go deep in the tournament.
Taylor Fritz is still chasing that dream Grand Slam title but is regularly in the mix in majors.
He has bettered or matched his best performance at each of the three Grand Slams already this year and, with home crowds behind him, he will be looking to build on last year's run to the quarter-finals of the US Open.
The American is also priced at 33/1.
