Arbitrage betting ("arbing") means betting on every possible outcome of the same event, spread across different bookmakers, using odds that are slightly out of line with each other. Done correctly, the combined stakes guarantee a profit no matter which outcome actually happens — the profit comes from the mismatch between bookmakers' odds, not from predicting the result.
A match has two possible outcomes. Bookmaker A offers odds of 1.95 on outcome one; Bookmaker B offers odds of 2.05 on outcome two. Splitting a stake across both sides, in the right proportion, locks in the same profit regardless of which outcome wins.
When a real arbitrage bet is placed, it's logged here as Open — the real match, the real odds taken at each bookmaker, the real stake, and the profit that's already locked in at the moment the bets were placed. That profit doesn't change based on the result; that's the point of arbitrage.
Once a match's real end time (tracked in UTC) has passed, it moves itself out of Open and into History without anyone needing to close it out manually — the balance updates at that point.
Match end times are stored in UTC, and settlement is checked automatically. Times shown on this page are converted to your device's local timezone for readability, but the underlying check always runs on UTC.
