Unlike free bets, which come with qualifying conditions and wagering requirements, BOG applies to every qualifying bet you place. A few bookmakers restrict BOG to races shown on ITV or feature meetings, excluding the smaller afternoon cards where drifts are more common. That means BOG triggers on a meaningful proportion of bets, and the average uplift when it does trigger is typically between half a point and two full points of odds. Research on UK racing suggests that around 35 to 40 per cent of runners drift to a higher SP than their morning price.

If you bet at a bookmaker with a consistently higher overround, you need a higher strike rate just to break even. The worst overrounds appear in ante-post markets, where the uncertainty justifies — in the bookmaker’s view — margins that can reach extraordinary levels. The overround also tells you something about the race itself.

If the exchange is at 7.0 and the bookmaker is at 6/1, the prices are closer, and after exchange commission the bookmaker might even be marginally better. Oddschecker is the most widely used in the UK and shows prices from all major bookmakers side by side, updated in near-real time. If the exchange offers 7.0 and the bookmaker offers 5/1, the bookmaker is taking a significantly larger margin on that runner, and you should either back on the exchange or find a bookmaker whose price is closer to the exchange level. On short-priced selections — odds-on or evens — the exchange commission can actually make the bookmaker price competitive or even better, because the commission is a fixed percentage of the profit regardless of the odds. The commission you pay on an exchange winning bet reduces your non gamstop betting sites uk effective odds. On feature races — the Champion Hurdle, the Gold Cup, the Grand National, Saturday afternoon handicaps at major tracks — the exchange market is deep enough that you can back at the displayed price without difficulty.

Around major meetings — Cheltenham, the Grand National, Royal Ascot — bookmakers offer boosted prices on selected runners. If the exchange offers 6.0 and the bookmaker offers 5/1, the bookmaker is competitive after commission. Instead of setting odds and accepting bets against them, the exchange matches punters on opposite sides of a bet.

The overround is 5.9 per cent, meaning the bookmaker has built a theoretical edge of just under 6 per cent into the market. It is the bookmaker’s theoretical profit margin before a single bet is settled. In practice, they always sum to more — typically between 110 and 130 per cent for horse racing — and that excess is the overround. In a perfectly fair market with no margin, the implied probabilities of all runners in a race would sum to exactly 100 per cent.

Flutter Entertainment, which owns Betfair, reported global revenue of $14 billion in 2024 across 13.9 million average monthly users, but the exchange is only one part of that portfolio, and liquidity varies enormously by market. Hundreds of thousands of pounds are matched, and the spread between the back and lay prices is narrow. That difference — roughly 10 per cent on the individual price — is the cost of the bookmaker margin. One person backs a horse to win; another lays it (bets against it winning). The betting exchange — Betfair being the dominant platform — operates on a fundamentally different model to a traditional bookmaker.

The practical approach for most punters is to use both. If you back at 6.0 (5/1) and pay 5 per cent commission on your winnings, your effective odds are 5.75 (approximately 19/4). On a Monday afternoon novice hurdle at a minor track, liquidity is thin. Over time, backing at exchange odds rather than bookmaker odds produces a measurably higher return on investment, assuming you can find liquidity on your chosen market. The exchange takes a commission on the net winnings of the winning side, typically between 2 and 5 per cent depending on the user’s activity level. The overround on the Grand National ante-post market can reach as high as 180 per cent — a level that would be considered predatory in any raceday market.
