LONDON—Emma Raducanu’s astonishing U.S. Open triumph could lead to a pot of gold worth around 20 million pounds ($27.7 million) over the next two years and that may be just the start, according to sports marketing experts.
The 18-year-old Briton was almost unheard before reaching the fourth round at this year’s Wimbledon, having earned around $40,000 since her senior debut three years ago.
