Betting Exchanges are fairly popular compared to online sportsbooks. A few have opened in the past year including Smarkets and SpiffX. In 2016 they will only get more popular as more players start to choose betting exchanges because of the peer to peer betting capabilities plus the fact that more players are on the system meaning more action.
Smarkets is about 2 years old but they are still considered very new in the world of betting exchanges with their other newest rival being Matchbook. Smarkets has a clean interface and has a unique story of how they launched by getting venture capital funding with a strong business plan to grow the site into a legitimate business which it is.
SpiffX is also relatively new to the scene. They are licensed in just Malta and not in the UK which is a bit of a letdown for UK players. Despite that, the site has more work to do to earn the confidence of punters wanting to test out their site and odds.
Matchbook is definitely a contender for best betting exchange around. If you like casino games, they have a casino on the side which most top bookmakers do have so this is almost standard. Some players like it, others hate the fact the have it as it's a distraction from betting on sports. Matchbook holds UK licenses and more, they are a serious bookie.
Betfair is considered by many as the first real legitimate betting exchange. They did it when a few others have tried and failed so the fact they have lasted for this long tells us they have done something right. As a sportsbook on it's own, they are ok and their casino is very good.
Betdaq was a popular up and coming betting exchange, so popular that Ladbrokes decided to buy them out completely.
In terms of making a decision on which betting exchange to pick, our top choices are Smarkets and Matchbook. Both sites have licenses by the United Kingdom Gambling Commission and they have their operations nailed down solid, treat players good, always pay and on time, decent odds and competitive commission rates to not get in the way of the marketplace.
