Live Betting (In-Play)

What is Live Betting (In-Play)?

Placing bets on a game while it's in progress, with odds that update in real time.

Last updated:February 22, 2026

Live betting (also called in-play or in-game betting) allows you to place wagers after a game has started, with odds adjusting in real time based on the score, time remaining, and momentum shifts.

Live betting now accounts for a large and growing share of total handle at sportsbooks. The markets move fast, and the models that set live odds can sometimes lag behind what's actually happening on the field.

Because of the speed required, live betting can be more susceptible to emotional decisions. Successful live bettors typically have pre-planned scenarios and target specific situations rather than reacting impulsively.

In practice

Lakers are down 12 at halftime. Pre-game they were −4.5 favorites; live, DraftKings hangs Lakers +5.5 at +115. If you think the market overreacted to a cold shooting first half (their pre-game true probability of winning was 65%), the live line may represent +5–7% EV.

Live markets move in seconds and typically carry 8–15% vig — much fatter than pre-game. Books rely on automated trading models that lag behind on injuries, momentum swings, and pace changes. Pro live bettors run dual-monitor setups with the broadcast delayed 5–8 seconds behind the arena feed, betting before the book’s model updates. Catching a stale in-play line before it moves is the closest thing to guaranteed CLV in US sports betting.
