Exchange statistics.
As reported in the NY Daily News:
Tennis is one of the fastest growing areas of Betfair’s sprawling business, which encompasses some five million bets a day. In July, for instance, the London Stock Exchange handled 12 million transactions; the same month Betfair handled 75 million. A record $60 million was wagered on this year’s Wimbledon final between Roger Federer and Rafael Nadal, according to Marks.
