What Is Live Betting in March Madness and How Do In-Game Odds Work?
Live betting March Madness gives you the opportunity to make wagers on games as they happen. Basketball is a perfect sport for wagering in-play, as there are often momentum shifts that create betting opportunities.
Example: a tight game at halftime followed by a 10-0 run can shift a spread from -2.5 to -6.5. This is where live betting creates opportunity.
| Game Situation | Market Reaction |
|---|---|
| Tight halftime game | Spread stays near pregame line |
| 10-0 run | Spread expands quickly |
| Momentum loss | Underdog cover probability drops |
