Live betting (also called in-game betting) lets you place wagers after a game starts, with odds updating in real time. Lines move on every play, possession, or pitch. Success requires speed, timing, and knowing how books price markets under pressure. This guide covers timing, liquidity, pricing differences, examples, and common mistakes. For a neutral primer, see Wikipedia: In-Play Betting.
How Live / In-Game Betting Works
- Dynamic pricing: Odds shift on events (touchdowns, runs, goals) and win probability models.
- Markets offered: Sides, totals, props, and micro markets (next play, pitch, or point).
- Data delay: Odds providers run a few seconds ahead of TV/stream—beware of latency.
Timing: When to Bet Live
- After scoring runs: Books adjust aggressively; value may lie with the opposite side if overreaction occurs.
- Breaks/halftime: Wider menus and bigger limits appear; time to compare across books.
- Late game: Liquidity is higher in NFL/NBA; volatility creates both opportunities and traps.
Liquidity by Sport
- NFL: Highest liquidity; sides/totals stay sharp. Props thinner.
- NBA: Fast possessions mean numbers shift constantly—reactive models, smaller limits.
- MLB: Pauses between pitches allow smoother pricing. Totals and next-inning markets common.
- NHL: Lower liquidity; moneylines/totals available, but props sparse.
- Soccer: Global liquidity is strong; markets adjust on goals, cards, corners.
Pricing Differences & Delays
- Spread vs ML vs Totals: Lines adjust together, but props lag more often.
- Latency: Book odds update faster than most video feeds; avoid “chasing” after a big play.
- Hold: Live markets often have higher vig than pregame. Shop multiple books if possible.
Practical Examples
NFL Example
Team A fumbles, opponent scores—market flips ML from -180 to +120. If you still project Team A near 60% to win, this may be value if your timing beats the next snap.
NBA Example
Runouts push total from 222.5 to 229.5. If pace is unsustainable, live Under has value before books stabilize.
MLB Example
Starter exits early; live total rises from 7.5 to 9.5. If bullpen is strong, inflated Over may be fadeable.
Strategy & Tips
- Have pregame numbers: Start with a projection baseline to anchor live bets.
- Pick spots: Focus on sports you can track closely (e.g., NFL stoppages, MLB pitching changes).
- Be fast: Use apps with instant bet acceptance; latency kills EV.
- Small units: Higher vig and volatility mean 0.25–0.5u per live bet is safer.
- Review results: Track if live bets beat the adjusted close—same principle as CLV. See CLV & Line Movement.
Common Mistakes
- Betting blind: Without pregame projection, it’s hard to tell if a price is value or noise.
- Latency chasing: Don’t click after a big play you saw on TV—book odds already moved.
- Oversizing: Live betting variance is huge; small units are safer.
- Forgetting vig: Effective hold is higher; long-term ROI requires sharper picks.
FAQs: Live & In-Game Betting

Which sport is best for live betting? NFL and soccer have the deepest liquidity. NBA/MLB offer frequent swings but require speed.
