Real-Time Odds Feed
A continuous data stream of sports events and their prices that keeps a sportsbook's odds current, especially for fast-changing in-play markets.
Definition
A real-time odds feed delivers live data on sporting events, scores and prices from a data or trading provider to the sportsbook, updating continuously as events unfold. For pre-match betting it keeps prices fresh, but it is critical for in-play (live) betting, where odds move second by second and markets must suspend the instant something significant happens, such as a goal, a wicket or a point. The feed carries not just prices but event states and triggers used to suspend and reopen markets. Because acting on stale prices is an integrity and liability risk, the feed's speed and reliability, and the sportsbook's latency in processing it, directly affect fairness and the operator's exposure. Many operators buy this data and pricing from specialist suppliers rather than modelling every sport themselves.
Worked example
During a live match, the odds feed pushes a goal event; the sportsbook instantly suspends the affected markets, recalculates prices from the new score, and reopens them, so no bet can be placed at the pre-goal odds during the change.
Why it matters
For learners, it is why live betting odds change constantly and pause the moment something happens. For professionals, the odds feed's speed and reliability are directly tied to trading integrity and liability, so latency and suspension behaviour are closely managed by trading and risk teams.
