Theory is fine, but here’s how it plays out when you’ve got money on.
A goal goes in
Team A score and the screen goes grey. Within seconds to a minute the traders recalculate and the market reopens at prices that reflect the new score. If you’d backed the scorers, your cash out value has probably gone up; if you’d backed the trailing side, it will have dropped. And if you’d been waiting to bet, you now can, at the new prices.
VAR rules out a goal
The ball hits the net, the market may show fresh prices or suspend straight away, and the review begins, often for one to three minutes. If the goal is disallowed, prices return to their pre-goal state. Bets placed between the goal and the decision are not always voided, so it’s worth knowing your bookmaker’s rule.
A tennis player calls the physio
A medical timeout suspends the market while the assessment happens, sometimes for several minutes. If the player carries on, the market reopens. If they retire, the bet is settled under the bookmaker’s retirement rules, which vary: some need a certain number of games or sets completed, others a full match. Tennis is the sport where reading the rules before you bet really pays.
Rain stops play in the cricket
Covers on, players off, market suspended until play resumes or the match is abandoned. If it restarts and finishes, your bets stand. If it’s abandoned, the bookmaker’s abandonment rules apply, and these often void markets that weren’t yet decided.
A faller in the racing
Most UK bookmakers don’t offer in-play betting on horse racing, but betting exchanges do, and when a horse falls or unseats its rider the in-play market suspends instantly while prices are rebuilt without it. It reopens quickly. Racing moves fast, so these pauses are frequent and short.
