What is Bet Delay?

Bet delay is the short pause, usually a few seconds, between a customer submitting an in-play bet and the sportsbook accepting it. During the delay the trading system checks whether the price is still valid; if the odds have moved or the market has been suspended, the bet is rejected or re-offered at the new price. The mechanism exists because live pictures and data reach different customers at different times, so without a delay someone watching a faster feed could stake on an outcome that is already known. The length varies by sport and by how volatile the market is, and it is set out in the operator's rules rather than shown on screen. In practice it means an in-play stake is never guaranteed at the displayed odds; a rejected bet simply returns to the balance.
