What is hedging?

Hedging is placing a bet on the opposite side of a wager you already have, to lock in a profit or limit a potential loss. It's common with futures and parlays: if your long-shot ticket is one leg from a big payout, you can bet the other side so you win something no matter what. Hedging trades away expected value for certainty — rational when the guaranteed amount matters more to you than the larger, riskier payoff.

Say you hold a futures ticket that pays $2,000 if a team wins the title, and they've reached the final. You could bet the opponent so that, either way, you come out ahead — perhaps locking $900 regardless of the result instead of gambling on $2,000-or-nothing. You give up upside in exchange for removing the risk of walking away with zero.

Hedging and arbitrage both bet multiple outcomes, but the intent differs: arbitrage is planned in advance to guarantee profit from a pricing gap, while hedging reacts to a position you already hold to manage its risk. A hedge is usually slightly negative-EV — you pay the vig for certainty — which is fine when locking a life-changing sum, and wasteful on small edges you should just let ride.

What is the difference between hedging and arbitrage?Arbitrage is planned in advance to guarantee profit from a pricing gap across books. Hedging reacts to a position you already hold to manage its risk, and usually costs a little EV for that certainty.

When should I hedge?Hedge when the guaranteed amount matters more to you than the larger, riskier payout — for example locking a big futures win. On small edges, hedging away the value is usually a mistake.
