Spread betting is an increasingly popular type of betting where your winnings - or losses - are determined by the the degree to which your prediction on an index or sporting event is correct. It has the potential for big wins, but also for big losses, so it's a bit of a dangerous game to play if you don't have the funds.

The affiliate payouts for Spread Betting are great - and usually range from about £50-£60.

Affiliate Merchants

Sporting Index is available on Commission Junction and Buy.At. They pay £60 for a signup. I like Sporting Index because they send you content and articles which are easy to throw up on a website.

City Index is on TradeDoubler and pays out £50 per sign up.

I've incorporated City Index and Sporting Index links into my own spread betting website, which you can check out here.
