The margin a bookmaker builds into horse racing odds is not fixed. Small-field races with well-fancied favourites tend to carry lower overrounds (closer to 110 per cent) because the market is more efficient and bookmakers compete harder on the headline price of the favourite. 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.

Check the exchange price on your selection before placing with betting sites not on gamstop uk a bookmaker. 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. On a Monday afternoon novice hurdle at a minor track, liquidity is thin. 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.

The betting exchange — Betfair being the dominant platform — operates on a fundamentally different model to a traditional bookmaker. That does not mean extra places are bad value — the additional place coverage can still be worth the wider margin, depending on the race — but it does mean you should not assume that an extra-places promotion is automatically a gift. Analysis from MatchedBettingBlog suggests that margins on extra-places markets can reach as high as 50 per cent. Bookmakers open with a cautious book and adjust as money comes in. The first show of prices in the morning — often called the early prices — tends to carry a wider margin than the Starting Price. On the raceday market itself, there are consistent patterns.
