Will It Void?
Player sits, game ties, or goes to overtime: how each prediction market settles it, quoted from its own rules.
Voided and refunded means the position is cancelled and your money comes back. Settles by a set rule means it is not refunded: it pays a price the platform sets (Kalshi's “last fair price”) or a fixed amount such as 50¢ on a tie. Settles on the result means the stats or score decide it as normal.
Pick a platform, a sport, the market and what happened. The checker shows how that platform settles it, in its own words, with the source and the date we last verified the rule. On Kalshi, a player prop is not refunded when the player sits: it settles at the last fair price Kalshi sets.
Settles at the last fair price Kalshi sets — not your entry price back.
“If a player is active but does not participate for at least one play during <game> all Contracts on that player for that <game> will resolve to the last fair price as determined by the Exchange in its sole discretion.”

Why “void” is the wrong word on Kalshi
Elsewhere, a player who doesn't play often means a void and a refund. Kalshi's contract terms do something else: the contract resolves to a fair price the exchange sets, so you get that price per contract, not your entry price back. The full explainer is in our Kalshi DNP rule guide, and ties are covered in Kalshi's tie rules.

Frequently Asked Questions
Does Kalshi void a player prop if the player doesn’t play?
No refund. Settles at the last fair price Kalshi sets — not your entry price back. Kalshi's NFL rule: “If a player is active but does not participate for at least one play during <game> all Contracts on that player for that <game> will resolve to the last fair price as determined by the Exchange in its sole discretion.”
Does Kalshi refund you if a player gets hurt during the game?
No. Once the player has entered the game, the contract settles on his stats. Kalshi's NBA rule: “If a given <entity> or <player> retires or is injured during <basketball game>, the markets on <entity> or <player> will settle based on the end-of-game statistics if <entity> or <player> have entered <basketball game>.”
What happens to a Kalshi combo if one leg is voided or settles at a fair price?
The whole combo goes to a fair price. The whole combo settles at a fair price Kalshi sets. It may, but need not, equal the product of the legs. Kalshi's NFL rule: “If any <component> resolves to a value other than zero or one (including where a <component> settles at a fair price, or is voided, pursuant to its corresponding <rule>), the Contract shall settle at the Fair Price.”
What happens to a Kalshi NFL game-winner contract if the game ends in a tie?
It depends on whether a Tie strike is listed. No Tie strike listed: both sides get 50¢. If a Tie strike is listed, it resolves Yes and the team strikes No. Kalshi's NFL rule: “If no “Tie” strike is listed, the Contract shall resolve such that "Yes" holders are paid $0.50, and "No" holders are paid $0.50.”
Does overtime count on Kalshi?
Yes, unless the contract names a period that excludes it. Overtime counts. Kalshi's NFL rule: “Unless otherwise specified, all overtime periods are included in determining the winner.”
Where do these rules come from?
From each platform’s own contract terms, rulebook or help center, quoted word for word with a link to the source and the date we read it (most recently 2026-11-11). Where a platform does not publish a rule for a case, the checker says “Not published” instead of guessing. The rules panel on each contract governs.
