Hedging a Bet: How to Lock In a Guaranteed Profit

Hedging means placing a second bet on the opposite outcome to reduce risk or lock in a profit on a bet that's moved in your favour. Done right, it turns a "will it win?" gamble into a guaranteed return. Here's how it works and when it's worth it.

What hedging is

Say you backed a team at 2.50 before the tournament, and they've now reached the final — their price to win has shortened to 1.80. Instead of sweating the final, you can bet the other side at 1.80 in the right amount so you win the same either way. That's a hedge.

How to calculate the hedge stake

Your original bet returns stake × odds if it wins. Divide that payout by the opposite side's odds to get the hedge stake, so both outcomes return the same amount. Our free hedge calculator does it instantly and shows your guaranteed profit and ROI.

When to hedge (and when not to)

• Lock in profit when a pre-match or futures bet has shortened a lot and you'd rather bank a sure return than gamble.
• Guarantee a payout on the last leg of a big parlay.
• Reduce variance if a single result would be a painful swing.

The trade-off: hedging usually gives up some expected value in exchange for certainty. If you have a genuine edge, letting winners run is higher-EV — hedge when the peace of mind (or the guaranteed number) is worth more than the EV you sacrifice.

Hedging vs arbitrage

They're close cousins. Arbitrage locks in profit before the event using two opposing prices that together imply an edge. Hedging is usually done after your bet has moved, to secure a profit that already exists. Same maths, different timing — and the calculator handles both.
