Kalshi Postponed Game Rules: What Happens To Your Market?

Here is the answer most traders are looking for, and it is not the one a sportsbook trained you to expect. Under the Kalshi postponed game rules written into each sport's contract terms, a game that is rescheduled and starts within 48 hours of its original date keeps your market open, and it settles on the final result of the makeup game. A canceled game that never starts within that window does not get voided and refunded. Instead, the contract "will resolve based on the last fair market price as determined by Kalshi." Your ticket settles at a price, not at a push.

That one sentence is the whole personality of Kalshi's sports fine print, and this article walks through the entire family of clauses that share it: postponement, mid-game suspension, shortened games, venue changes, forfeits, and the shootout trap. Every clause is quoted from the contract terms Kalshi actually files, because these markets have already produced one famous meltdown where the gap between the headline and the fine print cost real people real money. I will show you that case, and the one clause that quietly decides more of these situations than any other, further down.

The Quick Answer

Rescheduled within 48 hours: your market stays open and settles on the real result. Not played within 48 hours: your contract settles at the "last fair market price," decided by the exchange, with no void and no refund. The full clause-by-clause tour, including a storm-Sunday worked example where three tickets settle three different ways, is below.

The 48-Hour Clock

Start with the clause itself. The football game contract terms that govern Kalshi's NFL and college football winner markets (fetched August 12, 2026, along with every other rules document quoted in this article) state:

"If [the game] is postponed from its originally scheduled date but is rescheduled and begins play within 48 hours of its originally scheduled date, the market will remain open and will resolve based on the official final result of the rescheduled game. If [the game] is not started within that time period, the market will resolve based on the last fair market price as determined by Kalshi."

The baseball terms run the same 48-hour clock from the originally scheduled start time, which matters constantly in a sport with rain delays: a Tuesday washout made up Wednesday settles like a normal game, while a makeup folded into a series two weeks later settles at the last fair market price.

This is the sharpest difference between an event exchange and a book. A sportsbook typically voids a postponed game and returns your stake. Kalshi is a marketplace of contracts between traders, so there is no "house" to hand the money back; the exchange closes the market at a price instead. If that distinction is new to you, the mechanics are laid out in an exchange is not a sportsbook. The practical consequence: if you bought Yes at 40 cents, an implied 40% chance, and the market's last fair price before the cancellation was 60 cents, you profit from a game that never happened. If it drifted to 25 cents on lineup news before the postponement hit, you eat the loss just as readily, having paid for a 40% chance the market later priced at 25%.

Because the 48-hour clock only answers games that never start, the next question is the uglier one: what happens when the game starts and then stops?

Suspended Mid-Game: The 55-Minute Clause

Kalshi suspended game settlement splits a stopped football game at 55 minutes of game time. Before that mark:

"If [the game] is suspended or abandoned after kickoff and is not scheduled to resume or complete, and the suspension occurs before 55 minutes of play, all markets, except for those for which the relevant [time period] has definitively concluded (which will settle based on actual results from that completed [time period]), will resolve to the last fair price as determined by the Exchange in its sole discretion."

After 55 minutes, completed segments still settle on actual results, everything else settles at the last fair market price, and one override sits on top: "if after the suspension the governing league declares a winner or final result, all markets not yet settled under (a) shall resolve on that basis." The league's ruling beats the price.

Baseball handles the same problem through the sport's own "official game" machinery. The baseball terms say that if a game is "shortened, called, or otherwise ended before the regulation number of innings (e.g., due to weather, curfew, or mercy rule), and the governing body declares the game official and records a winner, the market for the full game will resolve based on that official result." A rain-shortened seven-inning win is a real win on Kalshi because it is a real win in the standings.

Notice what both sports are doing: the contract always asks first whether the result is already settled in the real world, and only reaches for a price when it is not. Soccer's terms make that principle explicit with a clause literally titled "Determined Result Governs," which says that once a scope's result "has been definitively determined," the contract "shall settle based on that determined result and shall not be settled at the last fair price," regardless of what happens to the match afterward.

Worked Example: One Storm Sunday, Three Payouts

Here is how those clauses interact on a single storm-hit NFL Sunday. A line of severe weather rolls through: one game is abandoned midway through the third quarter, around 40 minutes of play, with the home team up 17-10, and never resumed; a second game in the same region is postponed before kickoff and made up 10 days later. You hold three tickets across those two games, all bought pre-game:

Your Contract	Entry price	Governing clause	How it settles
Home Team Wins The Game	55 cents (55%)	Suspension before 55 minutes	Last fair price set by the exchange, likely near the 80-cent range a 17-10 lead commands, not $1.00
Home Team Wins The First Half	48 cents (48%)	That time period "definitively concluded"	Actual result: the half ended 10-7 home, so Yes pays $1.00
Winner Of The Second Game (Postponed Pre-Kickoff, Made Up In 10 Days)	30 cents (30%)	The 48-hour clock	Last fair market price at closure

The middle row is the one worth staring at. The first-half market pays out in full while the full-game market three lines above it on your screen settles at a price, from the same abandoned game. Traders who do not read the terms experience that as arbitrary. In reality it is two different clauses doing exactly what they say, and the gap between an 80-cent settlement and a $1.00 settlement on the same winning read is the cost of not knowing which one you bought.

That same segment logic is why a stopped game ripples through multi-leg positions unevenly, a problem with its own rules covered in what happens when a Kalshi parlay leg voids.

The Scope Trap: Shootouts And "Regulation Time"

The suspension clauses at least announce themselves as edge cases. The scope clauses are sneakier, because they decide games that finished normally.

Kalshi's soccer winner terms define multiple "result scopes" for the same match, and two of them can point in opposite directions on the same final whistle. For a "regulation time" contract:

"Draws at the conclusion of regulation play do not constitute a win, regardless of whether [the match] is subsequently decided by extra time, penalty shootout, drawing of lots, coin toss, or any other tiebreaker mechanism."

A "full match" contract inverts that: the team "officially confirmed by the organizer... as the winner," whether "by virtue of regulation play, extra time, penalty shootout, or any other tiebreaker mechanism," resolves Yes.

Picture a cup tie that ends 1-1 and goes to penalties. The side that wins the shootout advances, celebrates at midfield, leads every highlight reel. If your contract's scope was regulation time, that celebration is irrelevant to your ticket: regulation ended level, the Draw strike resolves Yes, and both team strikes resolve No. Football's tie clause runs on the same logic with a different payout shape: a game that ends tied after overtime resolves each team's strike to 50 cents, a 50% payout on a market you bought expecting a binary $1.00 or zero. Two traders can watch the identical match, both "call the winner," and only the one who bought the full-match scope gets paid. This class of confusion, where the official result and the emotional result of a game diverge, produces a steady stream of traders who are certain they were robbed and are actually reading the wrong clause. Before entering any market on a sport with ties, tiebreakers, or shootouts, the scope line in the rules is the first thing to check; Kalshi's resolution criteria walks through how to read it.

Venue Changes, Forfeits, And The Game That Never Happens

The rest of the family runs on the same two gears, a clock and an official result. The Kalshi venue change rules, from the football terms:

"If the venue of [the game] is changed but the designated home and away teams remain the same and the game is played within 48 hours of the originally scheduled date, the market will remain open and will resolve based on the official final result. If the home/away designation is reversed or if the game is moved outside the same scheduling week, the market will resolve based on the last fair market price as determined by Kalshi."

Moving a snowed-out game to a neutral dome keeps your market alive. Flipping who is the home team kills it into a price, because the thing you priced, home field, no longer exists.

Forfeits split on the opening kickoff: a pre-game forfeit settles team markets at the last fair market price, while a forfeit after the game starts resolves the forfeiting team to No and a declared winner to Yes. And my favorite clause in the whole baseball document covers the game that never needs to happen: if you traded a market on "Game 6" of a playoff series and the series ends 4-1, the terms settle it at the last fair market price. There is no result, so there is a price.

Futures Run On A Different Clock

Everything above is single-game logic. Kalshi's championship markets, the World Series and Stanley Cup class of contract, use title contract terms with a far more patient clause: a postponed or suspended title event keeps the market open until "the sooner of (1) the winner being reported or (2) two years following the [title] event's original scheduled date."

So a lockout that shoves a final back three months does nothing to a futures ticket, while 49 hours of rain can close out a single-game ticket at a price. Same exchange, same sport, different contract, different clock, which is exactly why the settlement basics in how Kalshi settlement works are worth internalizing before your first weather-week. Hockey traders see both clocks in one place, game markets and Cup futures side by side, as covered in how to bet NHL on Kalshi.

When The Rules Run Out: Rule 6.3(C)

I promised you the clause that quietly decides more of these situations than any other. It does not live in any sport's terms at all: it is Rule 6.3(c) of Kalshi's exchange rulebook filed with the CFTC, the exchange-level home of the same sole-discretion logic that runs through every "last fair market price" clause above:

"Kalshi has sole discretion to interpret a Contract's Terms and Conditions... To determine the payouts in these circumstances, Kalshi may implement the following methodologies: a. If available, Kalshi may use the last traded price of the Contract to determine the payout... b. If a last traded price is not available, or if Kalshi determines at its sole discretion that the most recent last traded price does not represent a fair settlement, the Outcome Review Committee will be responsible for making a binding determination of fair allocation. Determinations of the Outcome Review Committee are final and not subject to review."

"Final and not subject to review" is the phrase to sit with. The most instructive stress test of it was not a sports market at all: Kalshi's roughly $54 million market on whether Iran's supreme leader would be out of power settled at the last traded price of 9 cents, a 9% implied chance, under a fine-print death carveout rather than paying Yes holders $1, per coverage of the settlement. One documented trader had bought $303.90 of Yes at 6% implied odds, stood to collect about $4,588 at $1, and was paid $91.76. Users alleged the rules were unclear and the payout unfair, and a class action over the market's handling followed; Kalshi, for its part, conceded the rules were "grammatically ambiguous," reimbursed fees and net losses, and said similar contracts would be better explained in the future. Nobody in that market lost because they misjudged the event. The dispute, like the sports cases above, was entirely about which sentence in the terms controlled, and the process for fighting one is its own subject: what happens when a Kalshi market is disputed.

Read The Clock And The Scope Before You Trade

Zoom back out. Every clause in this article reduces to the two questions the exchange asks in order: is there an official result for the exact scope you bought, and if not, did the event happen inside the contract's clock? Official result inside the scope: you get the result. No result inside the clock: you get the last fair price, in the exchange's discretion, with fees already paid along the way (those have their own fine print). The 48-hour clock from the top of this piece is the version of that logic you will meet most often, because weather is the most common thing that breaks a sports schedule.

None of this makes Kalshi's sports markets untradeable. It makes them contracts, and contracts reward the person who read them. Two minutes in a market's rules tab, checking the scope line and the reschedule clock before you click buy, is the cheapest edge in prediction markets.

FAQ: Kalshi Postponed And Canceled Game Rules

Does Kalshi refund your money if a game is canceled? No. There is no void-and-refund mechanic like a sportsbook. A canceled game that is not played within 48 hours of its original start settles every open contract at the last fair market price the exchange determines, so a ticket bought at 20 cents that closed at 35 cents settles at a gain, and the reverse settles at a loss.

What happens to my Kalshi ticket if a game is rained out and played tomorrow? The market stays open. A game rescheduled to start within 48 hours of its originally scheduled start time resolves on the official final result of the makeup game, under both the football and baseball contract terms quoted above.

Do rain-shortened MLB games count on Kalshi? Yes, when the league says they count. If the governing body declares a shortened game official and records a winner, the full-game market resolves on that official result, exactly as it lands in the standings.
