I think Sunny is after companies that work in the betting field in the same way as trading firms in the City - they have people who trade on horse races and cricket matches instead of shares and gold. Sort of like being staked to bet, rather than sitting at home with the Geeks Toy and your own money.
I can't remember any of the names of these types of companies and google searching is proving fruitless, so I'm not much help.
These kind of set ups don't really exist on an official basis for obvious reasons. There are major asian arbing operations but sports bettors and betfair traders tend to be one man bands who co-op with other like minded people when it suits.
