Early close: When a Kalshi market stops trading before its scheduled close because the outcome is already known, as its rules allow; payout follows determination.
Some Kalshi markets are built to close as soon as the outcome occurs rather than at a fixed time. Kalshi's API flags these with can_close_early and an early_close_condition, and its rulebook lets Kalshi move a contract's expiration earlier when a value that meets the payout criterion occurs before the scheduled expiration date, with trading ending no later than expiration.
Example: a market asks whether a figure will be reached by year end. If it is reached in March, the market can close and be determined then instead of in December. Traders who spot an outcome can use "Request to Settle" in the market's options menu; Kalshi says its markets team reviews every request.
What to check: whether the rules include an early close condition. Kalshi also warns that a market left open is not an indication that the payout criteria have not been met, and that markets are not re-settled because an event appeared to be over while trading was still available.
