Arbitrage
📖 GlossaryDefinition
Arbitrage (arbing) means betting both sides of a game at different sportsbooks where the combined odds guarantee profit regardless of outcome. It exists when books disagree enough that both sides are +EV.
FanDuel: Team A at +155
DraftKings: Team B at +110
Bet $100 on Team A (FanDuel) + $130 on Team B (DraftKings) = $230 total If A wins: Collect $255 → Profit $25 If B wins: Collect $273 → Profit $43
No risk. Guaranteed profit. [/example]
Arbs are rare (1-3% return per opportunity) and short-lived. Speed matters — these windows close in minutes.
