Arbitrage found — this split guarantees a profit whichever outcome wins.

Arbitrage (or a "sure bet") happens when two bookmakers price opposing outcomes so generously that their combined implied probability falls below 100%. Splitting your stake in proportion to each price returns the same payout regardless of the result. Hedging works the same way to reduce risk on an existing bet, even when a guaranteed profit isn't available.
