 BETTING'S "everywhere man" Tom Waterhouse is believed to have been offered at least $500 million to sell his thriving bookmaking business, reports the Sydney Daily Telegraph.

It says: A leading UK-based betting operator is rumoured to have made the substantial offer to buy out the nation's biggest individual bookmaker.

But Waterhouse, 30, is remaining tight-lipped about the industry speculation and his spokesman gave only a firm "no comment" when asked by News Limited about the takeover bid.

"We get at least one call a week about this (takeover bids)," the spokesman added.

Waterhouse's online business TomWaterhouse.com is estimated to have betting turnover of more than $500 million a year, giving him a decent chunk of Australia's $20 billion a year betting industry.
