How CS2 arbitrage is calculated
An arbitrage exists when the inverse odds of both sides add up to less than 1. Stake each side in proportion to its inverse odds and both outcomes return the same amount. With 2.12 and 2.08, the inverse sum is 0.9525, a 4.75% gap, so a 100 total stake returns 104.99 either way.
Formulas
- Inverse sum
S = 1 / odds A + 1 / odds B- Arbitrage margin
arb % = (1 - S) x 100, an arb exists when S < 1- Stake on side A
stake A = total x (1 / odds A) / S- Payout on either result
payout = total / S
Worked example: 2.12 vs 2.08, 100 total stake
| Inverse sum | 0.9525 |
|---|---|
| Arbitrage margin | 4.75% |
| Stake A / B | 49.52 / 50.48 |
| Payout either way | 104.99 |
| Profit | 4.99 |
What it does not tell you: The math assumes both bets are accepted at those exact prices. Odds move, stakes get limited, accounts get restricted, and the two books may settle walkovers or map forfeits differently. Check settlement rules on both sides first.
Arbitrage FAQ
What is CS2 arbitrage betting?
Arbitrage happens when prices on opposite sides are high enough that staking both sides can return more than the total stake if both bets stand.
Why do settlement rules matter?
If one book voids a bet and another grades it, the hedge can break. Match, map, overtime, forfeit, and roster rules should match before staking.
Can this calculator find live arbitrage automatically?
No. It calculates an opportunity from prices you enter. Automatic live discovery requires the future sportsbook odds API layer.
Execution Notice
Arbitrage depends on both prices still being available, accepted, and graded under compatible rules. Recalculate after any odds move.
