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, Soccer Combo, NHL Combo, or MLB Combo. A single-game combo includes its matchup, such as NE vs SEA NFL Combo. Each selection keeps its own sport, league, and matchup.
On Culture and its configured market pages, the Combos filter shows events
with at least two currently tradable predictions supported by the Protocol
vault’s within-event combination policy. The button appears only when the
selected page and topic contain an eligible event. Multiple outcomes alone do
not imply combo support, and mutually exclusive events are excluded. Eligibility
does not guarantee that a quote is currently available. If a selected topic has
no eligible events, the filter turns off and the button is hidden.
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, including the
existing expiry rules for Credits.
