Every Prediction Pick market has a defined set of rules that determine when and how it settles. The resolution source, timing, and criteria are all established in advance, and outcomes are determined strictly according to those terms.
Who determines the outcome?
Each market is settled by the exchange it's offered through, according to that exchange's official rules:
UDX: settled under UDX's own contract rules and market descriptions, per the UDX Rulebook and UDX Notices.
Kalshi: settled by Kalshi's Outcome Review Committee under the Kalshi Rulebook.
Nadex: settled by Crypto.com | Nadex under the Nadex Sports Event Trading Rules.
Underdog Predict reflects the settlement from the exchange a market is offered through. We do not independently determine or override market outcomes.
Live scores and stats
Live scores and stats displayed in the Underdog app during a Prediction entry are sourced from a third-party provider and are considered unofficial.
All Prediction entries are settled using the official results provided by the exchange at the end of the match or game — not by what the in-app display showed at the time the entry was placed.
When do markets settle?
Most single-game markets settle within a few hours of the event concluding. Payouts are typically processed within 24 hours of settlement.
Futures markets settle once the final outcome of the season or competition is officially determined.

What happens if a pick in my Prediction parlay is canceled, ties, or a player doesn't play?
UDX & Kalshi
If a pick in your Prediction parlay is canceled (e.g., due to weather), ends in a tie, or involves a player who does not play (DNP), that position settles according to the rules of the underlying market. This applies to every pick type in the parlay, including team outcomes, player props, and individual matchups like tennis. Instead of settling at $0 or $1, the affected position typically settles at a fair market price.
The parlay is not refunded or canceled. The payout is calculated by multiplying the settlement values of all positions, including the adjusted value of the affected position:
If any other position is incorrect, it settles at $0, so the entire parlay settles at $0.
If all other positions are correct, they settle at $1.00, and the payout is based on the adjusted value of the affected position(s).
Because the adjusted value can be higher or lower than what you paid, your payout may be more or less than your original cost, even when every other pick is correct.
For example, if one position settles at $0.70 due to a DNP and two other positions settle at $1.00, the parlay pays $0.70 per contract ($0.70 x $1.00 x $1.00).
Nadex
If a parlay is unsettled and a leg is canceled based on the Event Canceled Rules (e.g. due to weather or injury) or ends in a Tie, then the parlay remains active (unless a separate leg loses).
Upon final settlement, the payout is calculated by multiplying the settlement prices of all legs together — including the VWAP price of the canceled leg.
