Yes, you can now parlay on Polymarket. Polymarket added combos to its international exchange on June 10, 2026, at the start of the FIFA World Cup, and opened them to all Polymarket US app users on August 19, 2026, after a short beta. A combo joins several outcomes into one position that pays only if every leg wins.
How Polymarket combos work
You pick the outcomes you want, for example several match results, and Polymarket quotes a single price for all of them together. If every leg wins, each share pays $1. If one leg loses, the position is worth nothing. As with any Polymarket position, you can sell before settlement if there’s a buyer.
Polymarket self-certified its sports combo contracts with the CFTC in 2026 for its US exchange, where, after a beta from early August, they opened to all app users on August 19, 2026.
Fees
Combos carry their own taker fee rate of 0.05, using the same formula as Polymarket’s other markets: shares × 0.05 × price × (1 − price). They don’t inherit the fee rates of the underlying markets. Makers pay nothing, as everywhere on Polymarket.
Is a combo good value?
If the legs are independent, a fair combo price is roughly their prices multiplied together: three legs at 60¢ come to about 21.6¢. If the quoted price is clearly above that, you’re paying a premium for packaging the legs together. Check by looking up each leg’s price on its own.
