After a 21-year-old Federer won Wimbledon for the first time in 2003, Nick Newlife of Oxfordshire, England, bet approximately $2,000 on the Swiss youngster setting the all-time record for most victories at the tournament. He received 66/1 odds on Federer winning seven titles by 2019.
Newlife died in 2009 at age 59 and left the betting slip in his will to Oxfam, an international charity collective devoted to fighting poverty. The organization stands to make $158,056 if Federer defeats Novak Djokovic in Friday's semifinal and hoists the trophy after beating Andy Murray or Jo-Wilfried Tsonga on Sunday.
Graham Sharpe, who works for the British bookmaker William Hill, took the "unique" specialty bet in 2003. He said it's drawn a lot of attention, including from its prime subject.
"A number of people have drawn Federer's attention to this bet," he told the BBC. "I don't know whether he's thinking about this hugely philanthropic gesture to Oxfam. It's certainly not going to harm his reputation if that's a side project."
