The US Open men's and women's singles winners will get $5m (£3.7m) each as part of a total pot of $90m (67.4m) in prize money, which the tournament says is "the largest purse in tennis history".
The amount for the eventual singles champions is a 39% increase on 2024 when it was $3.6m (£2.8m), while the total purse has gone up 20% from the $75m (£57.8m) awarded last year.
In comparison, the total prize money at Wimbledon this year was £53.5m, with the men's and women's singles winners getting £3m apiece.
Players who are knocked out in the first round at the US Open will get $110,000 (£82,400), which is an increase of 10%.
