How to Hedge on Polymarket and Lock In Profit (Step-by-Step)
Every Polymarket match has two sides, and when it ends exactly one of them pays $1 a share. Hold one share of each side and you're paid $1 whoever wins. That's how you hedge on Polymarket. Once the price has moved your way, buy the other side, and the profit is locked in whichever side wins. Then merge each pair back into $1 of cash, without waiting for the result. This guide shows the maths on a real match, when a hedge is worth it, the mistakes that cost money, and how to do all of it in the OddsFantasy trading terminal.
Hedging means buying the other side of a market you already hold, so your result no longer depends on who wins. A Polymarket share pays $1 if its outcome happens and nothing if it doesn't. In a two-sided market such as a match winner, one share of each side is a pair, and a pair always pays exactly $1.
So the question is what the pair cost you:
On 29 October 2026, Counter-Strike's Eternal Fire played Astralis, best of three. These are real Polymarket prices from that night:
Say you bought 16 Astralis shares at 50¢, $8 in all, while they were behind. Ten minutes later they were at 84¢. If you'd bought 16 Eternal Fire shares then, at about 16¢, each pair would have cost 50¢ + 16¢ = 66¢, and paid $1. That's 34¢ locked in on every pair, about $5.44 on 16 pairs, whichever team won.
An hour later the price had swung back. A hedge at that point cost 42¢ a share: 50¢ + 42¢ = 92¢ a pair, 8¢ locked in. That's about $1 on the position after the hedge's fee. Still a profit, but most of the move had gone.
Then Eternal Fire came back and won the series 2-1. Unhedged, the $8 on Astralis was lost. Hedged, the pairs still paid out, and the profit was already locked in.
Only after the price has moved your way. Before the match, both sides together cost about $1 plus the spread (63¢ + 38¢ = $1.01 here), so a hedge then locks in a small loss. The bigger the move in your favour, the cheaper the other side gets, and the more each pair locks in.
You don't have to wait for the result. A merge turns each pair straight back into $1 of collateral.
For bots, open Auto exits in Positions, create a preset, and on the Live step tick Merge hedged positions after kickoff. Any pairs your bot ends up holding in a live match are merged into cash for you.
A hedge caps the upside. Unhedged, an Astralis win would have paid $16 on $8. Hedged, you take the locked amount whichever team wins. The hedge leg is a market order, so it pays Polymarket's taker fee and OddsFantasy's builder fee. The ticket's profit and loss figures already include those fees. See Polymarket fees explained for the numbers.
If you'd rather exit at a set time than hedge, Polymarket auto sell closes a position whenever you choose. For trading during a match, see Polymarket live trading.
Prediction markets carry real risk. Only stake what you can afford to lose, you must be 18 or over, and check that Polymarket is available where you live.
Yes. Buy the other side of the market you hold. One share of each side always pays $1, so if the two prices you paid add up to less than $1, the difference is locked in whichever side wins.
The same number of shares you already hold, not the same dollars. Equal shares make every result pay the same amount.
It turns each Yes and No pair, or each pair of two teams' shares, back into $1 of collateral before the market resolves. In OddsFantasy it's the Merge tab in the Close dialog, or Actions, then Merge for every pair at once.
No trading fee: a merge isn't a trade. The hedge itself is a trade, and a market order pays the taker fee.
No. After resolution you redeem the winning side instead. Merge while the market is still open.
No. It only locks in a profit when the pair costs less than $1, which happens after the price has moved your way. Hedge before that and you lock in a small loss.
