Combos

Polymarket offers Combos, which let you combine multiple market positions into a single trade.

What are Combos?

Each position in a Combo is called a leg. For the Combo to win, every leg must resolve in your favor. If one leg loses, the entire Combo loses.

Adding more legs can increase the potential payout, but also makes the Combo less likely to win.

Combo Legs

Combos can include different types of markets, such as moneylines, spreads, and totals.

Be careful when combining legs that conflict with each other, since the Combo can only win if every leg resolves in your favor.

Combos vs. Parlays

Combos and parlay markets both depend on multiple outcomes, but they are structured differently.

Parlay markets are created with multiple linked conditions, while Combos let you choose and combine multiple market positions into one trade.
