Sponsorship and PR experts have predicted Emma Raducanu could earn up to £1billion across her career - with many big-name brands circling after her US Open win.

The teenager, who grew up in Bromley, Kent, is one of the hottest names in sport after she stunned the world by becoming the first qualifier in history to win a Grand Slam.

She did so at 18 years of age without dropping a set, leading to many considering Raducanu as one of the best British sporting prospects in generations.

Max Eisenbud, a vice-president of talent firm IMG, told The Mail on Sunday that he has endured one of the busiest weeks for years in his marketing career thanks to his teenage client.

Eisenbud is experienced when it comes to helping enhance the brand of tennis stars. He was instrumental in securing multiple Grand Slam champions Maria Sharapova and Li Na multi-million pound deals in their respective careers.

Raducanu’s two current endorsement deals - with Nike and racket supplier Wilson - are worth just £100,000-a-year combined, with both being rolling one-year contracts - and these are expected to either be quickly renewed for at least 10 times as much or replaced by rival brands.

The teenager’s appeal is global, and many brands from fashion, automotive, soft drinks and beauty sectors are reportedly set to contact Eisenbud regarding Raducanu, with names such as Uniqlo, Aston Martin, Lacoste, Chanel and Tiffany & Co. as well as several cryptocurrency companies.

Rumours suggest the world number 23 could pen a deal with Tiffany worth over a million annually, while insiders say endorsement deals worth £5million or more over the next year could be signed soon.

In the sportswear realm, British firm Castore - who have a deal with three-time Grand Slam winner and domestic tennis icon Andy Murray - and historic Formula 1 manufacturer McLaren are chasing her signature, as well as the England cricket team.

However, Nike are believed to be leading the race with Adidas monitoring the situation.

Conrad Wiacek, the head of sport analysis at GlobalData, predicted Raducanu to sign several lucrative sponsorship contracts before the Australian Open - the next Grand Slam on the calendar - begins in January.

“The period between the US Open and the Australian Open is the traditional time to get deals signed,” the expert said. “Leisurewear, sports, health, fitness and lifestyle brands are all very interested.

“There is no one like her in British tennis with Andy Murray’s best days behind him.

“What is massively in her favour is the fact she is connected to the three distinct and lucrative markets in in North America, Europe and Asia due to her heritage. That sends her earnings potential off the charts.”

The current highest earning sportswoman in the world is Raducanu’s colleague, Naomi Osaka. The 23-year-old earned $55m in sponsorship last year plus an additional $5m in tennis prize money.
