ποΈ Combos
Combos are multi-leg parlays. Instead of buying one prediction-market outcome, you select multiple eligible legs and receive one combo position that pays only if every leg wins.
Open Combos from the app header or go directly to Combos.
Step-By-Step: Building And Placing A Combo
Step 1 β Open The Combos Page
Go to /app/combos. The page opens on the market browser with your slip panel on the right (desktop) or below (mobile).
Step 2 β Find Markets To Add
Browse the eligible market list. You can search by keyword or scroll through active markets. Not every Polymarket market is combo-eligible β only markets the Combos system accepts will appear here.
Step 3 β Add Legs To Your Slip
Click a market to open its outcome selector. Choose YES or NO, then add it to your slip. Repeat for each additional leg you want to include.
Your slip panel updates in real time showing:
- each selected outcome
- the combined implied odds
- the estimated payout multiplier
Step 4 β Review The Slip
Before entering an amount, review every leg. Check that each selected outcome is the one you intend to trade. Removing a leg is easier than unwinding a placed combo.
Step 5 β Enter Your Amount
Type the USDC amount you want to put on the combo. The slip shows your estimated payout if every leg wins. Use conservative sizing β long combos have low win probability even when each leg looks likely.
Step 6 β Request The Final Quote
Click Get quote (or the equivalent confirm button). Olympus fetches a live quote from the Combos system. The confirmed price may differ from the estimate if any market prices moved since you built the slip.
If the quote is too far from the estimate, review whether any market moved significantly and edit or retry.
Step 7 β Confirm And Place
Accept the quote to submit the combo. Once placed, the combo appears in your My Combos tab with pending status.
Step 8 β Track Settlement
Each leg settles independently. You can monitor status from the My Combos view. If every leg resolves in your favor, the full payout is credited. A single losing leg means the combo loses.
Pricing And Fills
Olympus shows an instant local estimate while you build. The final quote is requested when you place the combo, so the confirmed price can move if market prices change.
If a quote is unavailable, contradictory, expired, or too far from the expected price, edit the slip and try again instead of forcing the trade.
Tracking Combos
After placement, Combos can show your open and historical combo positions.
Depending on position state, you may be able to:
- view the legs
- track pending or resolved outcomes
- close early when supported
- share the combo slip
- share a PnL card after settlement
Combo positions settle based on all legs. A single losing leg can make the full combo lose.
Good Practices
- keep the number of legs manageable (2β4 legs is a good starting range)
- check each leg before placing
- use smaller sizing than single-market trades when odds are long
- treat local payout previews as estimates until the final quote is accepted
- avoid combining markets that depend on the same uncertain event unless that is intentional
