Amounts traded on US open tennis

I am really surprised at the amount of money traded. Does anyone have any ideas where the money comes from? You don't see the average punter run into Coral to place tennis bets. I thought tennis wouldn't be that popular.

Is the majority from the UK? I am guessing that most are traders as how many punters can lump in 50,000 after every point.

I am also assuming because of the set up of tennis i.e movement of odds, it's safer to put 50,000 into tennis than on the horses.

£63m traded on the US Open final, which is particulary huge.

Tennis has a propensity to flip flop a lot so that can drive large traded volume. Especially in long competitive matches.
