Betfair Exchange is the closest thing to a "fair" betting product that traditional bookmaking has produced. By matching backers and layers directly, it removes the bookmaker's structural advantage — you're betting against other punters, not against a firm with a built-in margin. The commission (typically 5% on winning markets, less with loyalty discounts) is the only rake. This is genuinely good.
Where Betfair Falls Short
- →Liquidity on niche events is thin — try matching a £500 bet on Slovak football at 3am
- →UK-focused — international events (US politics, tech milestones, global economics) have minimal markets
- →Lay betting complexity — explaining lay bets to new users takes about twenty minutes
- →Account restrictions — Betfair does restrict "bonus abusers" and sharp traders on the sportsbook side
- →Complexity of in-play trading without an API requires fast manual action
What Prediction Markets Do Differently
Prediction markets like Boromarket trade YES/NO shares on a single binary outcome. There is no lay bet — you buy YES or you buy NO. The price is denominated in probability (a 60¢ YES share means the market thinks there's a 60% chance of the event happening). No margin, no overround, no house edge beyond the spread between YES and NO.
The key difference: Betfair is primarily a sports betting exchange. Boromarket is a prediction market covering sports, politics, technology, economics and culture — with a global user base pricing every market simultaneously.
For UK horse racing? Betfair's liquidity is unmatched. For the US election outcome, who wins the next Oscars, or whether a central bank raises rates? Prediction markets win decisively.
