# Combos

A combo is multiple predictions on one slip. Tickets spanning different sports use **Sports combo**. Multiple games from one sport use **NFL Combo**, **CFB Combo**, or **Soccer Combo**. A single-game combo includes its matchup, such as **NE vs SEA NFL Combo**. Each selection keeps its own sport, league, and matchup.

Polymarket event markets can be combined with other selections. A quote requires
a maker that supports the combination; Vault currently quotes these markets only
as single-selection entries.

Polymarket markets with named outcomes are shown as Yes/No propositions. For
example, “Will Elena Rybakina beat Aryna Sabalenka?” binds Yes to Elena Rybakina's
Polymarket token and No to Aryna Sabalenka's. Prices and settlement use those
same tokens; the displayed rules preserve the provider's resolution terms and
state the local mapping. A confirmed final equal 0.5/0.5 event settlement voids
the market under Longshot's
[void policy](/documentation/resolution-payouts#voided-markets), including the
existing expiry rules for Credits.

### How it prices

Three independent 50% legs have a 12.5% chance of all winning. Correlated legs can differ.

Market makers have discretion on how they price the slip. The best price during the auction window will be the executed price.

### Fees

Fees apply only to winning profit. See [fee details](/documentation/resolution-payouts#fees).
