Most bookmakers cap BOG payouts — some at a maximum enhanced payout of 500 pounds, others at a maximum uplift of a certain number of odds points. On horses that drift — less money than expected, price lengthening — BOG gives you the benefit of the higher SP. On horses that are supported in the market — money coming in, price shortening — BOG adds nothing, because the SP is lower than the price you took. Best Odds Guaranteed is one of the most powerful tools available to horse racing punters, and it is routinely undervalued.
Yet the majority of bettors place their bets with whichever app they last used, at whatever price happens to be on screen, without checking whether a better number is available elsewhere. @ScottyPick6 Scotty thank you so much for the winnings from the Saturday webinar. Biggest payout of my life! Took down that LP5 @BelmontStakes today!
The aggregate effect across 20 runners adds up to a much wider margin than in a six-runner race. Across UK and Irish horse racing, typical bookmaker overrounds range from about 110 to 130 per cent. Understanding the typical ranges gives you a framework for evaluating whether the price you are being offered is competitive or padded. The margin a bookmaker builds into horse racing odds is not fixed. 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.
Winners are paid out of full track odds on your Straight wagers and track odds up to a fixed odds max amount for your Exotic wager. But check the cap on the maximum stake, because enhanced odds are almost always limited to small bets — one or two pounds, occasionally five. Second, the exchange price reflects pure market opinion without any built-in margin, which makes it a more accurate indicator of the horse’s implied probability. First, it gives you a benchmark for whether the bookmaker prices are competitive.
The individual difference may be small — perhaps 5/1 versus 11/2 — but across hundreds of bets over a year, that cumulative margin is the difference between a profitable punter and a losing one. The take varies from state to state and the money is used to pay taxes, purse money for the horsemen, expenses at the track, and the track’s profit. 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.
When should you use the exchange, and when should you use a bookmaker? There is a subtlety that experienced exchange users understand and newcomers often miss. 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 non gamstop betting sites 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.
If you are betting early in the day and BOG is on offer, take the best available bookmaker price. If the exchange back price is 8.0 and the best bookmaker is offering 6/1, the bookmaker is taking a significantly wider margin on that horse. Here is the workflow that experienced punters follow, stripped of anything unnecessary. And some operators apply BOG only to bets placed after a certain time in the morning, which means very early ante-post-style wagers do not qualify.
The overround also tells you something about the race itself. 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.
