Can Emma Raducanu become sports' first billion dollar woman?

London (CNN Business) Emma Raducanu's US Open victory netted the 18-year old Brit $2.5 million in prize money. She's about to make much more from sponsorship deals.

"I think Emma will earn well over $100 million [in the next calendar year]. She'll eclipse all the men," said Jonathan Shalit, the chairman of InterTalent Group, a London-based talent management agency.

Shalit, who represented British double gold Olympic boxer Nicola Adams, added that the world's biggest brands will be "knocking down Emma's door." That could lead to lucrative sponsorship deals across fashion, jewelry, cosmetics, skincare and haircare, he told CNN Business.

Raducanu defeated Canadian teen Leylah Fernandez in straight sets on Saturday, becoming the youngest grand slam winner since Maria Sharapova won Wimbledon in 2004 at the age of 17. She is also the first player in history to win one of the top four tournaments after gaining entry by fighting through qualifying rounds. Her victory made the front pages of newspapers around the world on Sunday and Monday, including The New York Times and The Guardian.

In China , Raducanu's win was hailed by state-run media and trended on social media platform Weibo, where fans celebrated her Chinese heritage. She was born in Canada to a Chinese mother and Romanian father before moving to the United Kingdom when she was two years old.
