Emma Raducanu stands to earn a staggering $5million (£3.9m) if she lifts the US Open trophy for a second time next month – more than double the amount she pocketed during her fairytale run four years ago.
The 22-year-old stunned the tennis world in 2021 by winning in New York as a qualifier, scooping $2.5m (£1.8m) in prize money in one of the sport's most remarkable breakthroughs.
Now, with the prize pot having ballooned to record levels, tournament organisers have confirmed that this year's men's and women's singles champions will each receive $5m – the richest individual payday in Grand Slam history.
The total player compensation package for the 2025 US Open has also hit an all-time high of $90m (£70m), up from $75m in 2024 and dwarfing the figure from Raducanu's winning year.
That dramatic rise comes amid mounting pressure from top players for improved pay distribution across the tour. First-round losers in the main draw will now receive $110,000, while the champions in the men's, women's and mixed doubles events will each share $1m per title.
Raducanu, Britain's top-ranked female player, is preparing for her return to Flushing Meadows with a new – and familiar – face in her corner. Earlier this week, Mail Sport revealed that she has appointed Rafael Nadal's long-time coaching ally Francisco Roig to guide her through the US hard court swing.

Roig served as a long-time member of Nadal's coaching team, working alongside Toni Nadal and later Carlos Moya during many of the Spaniard's 22 Grand Slam wins, before going on to work with Matteo Berrettini.
His arrival marks Raducanu's eighth coaching partnership since turning professional.
Discussions between the pair began during Wimbledon, and Roig is now in Cincinnati to help her prepare for the final WTA 1000 event before the last major of the year.
After a stop-start few seasons plagued by injuries and instability, Raducanu will hope that a steady partnership with the experienced Spaniard – combined with a healthy run of form – can set the stage for another deep Grand Slam push.
Should she go all the way again in New York, it won't just be silverware waiting at the end – it'll be the biggest cheque of her career.
