Handle
The total amount of money wagered on an event (or across multiple events) at a sportsbook. The handle includes all bets on all sides. It’s a measure of betting volume or liquidity for that fight/game.
The Canelo vs. Crawford fight might draw a **handle** of \$20 million nationwide. If one sportsbook’s handle is \$5 million on the fight, that’s the sum of all bets they took on both fighters combined.
