When a prediction market contract reached expiry, it normally means the contract has reached its rule-defined trading cutoff or end condition. It does not by itself prove the outcome, finalize a resolution, credit a payout, or void the contract; those later stages depend on the contract terms, designated source, and venue process.

Key Takeaways

Expiry usually closes or limits trading; it is not the same as outcome determination.

The official source may publish after the real-world event or scheduled close.

“Expired,” “closed,” “determining,” “resolved,” “settled,” and “paid” are separate states.

Save the contract rules and timeline before assuming a delay is an error.

Escalate only after comparing the observed state with the venue's documented next step.

What does it mean when a prediction market contract reached expiry?

Expiry is a boundary defined by the individual contract. It may be a listed date and time, the occurrence of an event, or another condition in the rules. Kalshi describes markets that close when an outcome occurs and markets that close at a stated time, and directs users to the market's own timeline and payout section.［2］ That is a platform example, not a universal definition.

After expiry, new orders are normally no longer eligible, and open orders may be canceled or expire according to their time-in-force. The account may still display a position because the economic result has not yet been determined. A position row remaining visible is therefore not proof that trading is open or that settlement failed.

The useful first step is to record the exact status label, expiry time, time zone, rule version, position, and any open-order disposition. Once the venue confirms that the contract has reached its rule-defined cutoff, do not keep resubmitting; verify the order ledger instead.

Which stages can follow an expired contract?

The labels vary, but the underlying sequence can be separated into evidence-based stages:

Stage	What it normally establishes	What it does not establish
Trading close or expiry	New trading has ended under a rule	The winning outcome
Outcome determination	The designated data is being evaluated	A final, undisputed result
Proposed resolution	A candidate outcome has been submitted	Final settlement if a dispute window exists
Final resolution	The venue or protocol has finalized an outcome	That every account ledger already updated
Settlement or redemption	Contract value is converted or made redeemable	Withdrawal availability in every system
Account credit	The balance ledger reflects the result	Bank or blockchain withdrawal completion

Kalshi states that the contract's terms identify the outcome rules, information, and source, and that determination happens after expiry using those materials.［1］ Its Market FAQs distinguishes market close from determination and says winning contracts are credited to the cash balance once the market is settled.［3］ Polymarket documents a different model in which a result can be proposed and disputed through an oracle process.［4］ These examples show why the status label must be interpreted through the venue's own rules.

If the page says “expired” but not “resolved,” wait for the next documented stage rather than treating the visible market price as the answer. Prices reflect trading before the cutoff; they are not substitutes for the resolution source.

Why can outcome determination take longer than the event?

The real-world event and the contract's evidence may finish at different times. An election can end before a designated authority certifies it. An economic release can have a scheduled publication time after the measurement period. A sports or weather source can correct preliminary data. The contract may also require a threshold, official statement, or complete reporting period rather than the first public headline.

Kalshi notes that its determination timing is often dictated by when the named source agency supplies data.［1］ Do not turn that example into a promised one-hour or same-day service level. A source delay, correction, holiday, time-zone difference, or ambiguous edge case can change the timeline permitted by a specific rule.

Check four items:

The exact expiry condition and time zone.
The named resolution source and required data field.
Any fallback source or exceptional-circumstance clause.
The venue's determination, challenge, and finalization process.

The resolution-rules guide explains how to turn these clauses into a pre-trade worksheet. At expiry, use the saved worksheet to compare what the contract promised with what the status page now shows.

What happens to open orders and held positions?

Open orders generally stop being executable when trading closes, but the venue's order history controls the actual result. Verify whether each order was filled, partially filled, canceled, or expired. A position is based on fills, not on the original requested quantity, so use the execution ledger rather than the order ticket.

Held contracts normally remain in the portfolio until resolution, settlement, redemption, or another rule-defined disposition. Do not delete records or assume a zero available balance means a loss. Collateral can remain reserved while the outcome is pending, and different ledgers can update at different stages.

If the contract becomes void rather than resolving Yes or No, follow the separate guide to what a voided contract means. Void treatment is an exceptional rules path; it should not be inferred merely because a market has expired without an immediate result.

When should you investigate a missing payout?

Start only after the market shows a final state. A contract that is expired or determining has not necessarily reached the point at which a payout is due. If the venue requires a redemption action, confirm whether it is automatic or user-initiated. Then compare the held outcome, filled quantity, settlement price, account ledger, and any redemption or transfer record.

Use the missing payout after settlement workflow when the market is explicitly settled but the expected credit is absent. That workflow is intentionally later than this one. It distinguishes a venue ledger credit from redemption and withdrawal.

Do not use a countdown, a search-engine result, or a social-media post as proof that settlement should have occurred. The controlling evidence is the contract, source, official status history, and account ledger.

What evidence should you preserve during the wait?

Create a small timeline before screens or rules change. Save the contract identifier and title, position side and quantity, fill records, expiry time and time zone, timeline section, full resolution rules, designated source, current status, and capture time. Keep original files or PDFs where the venue offers them.

If a status changes, add a new timestamped capture rather than replacing the old one. Record the exact transition—for example, expired to determining or proposed to disputed. This makes it possible to show whether the system followed its published sequence without relying on memory.

If support is needed, ask which stage the contract is in, which rule governs the next transition, whether the named source has published the required value, and whether user action is required. Never send a password, recovery phrase, one-time code, private key, or remote-control access to someone claiming to accelerate settlement.

What if the announced result looks wrong?

First compare the announced result with the contract wording and named source. A public consensus or event headline may use a different threshold, measurement window, geography, revision, or official body. Preserve both the original rule and the source record before the platform updates its page.

If the venue offers a dispute process, follow its deadlines and evidence format. The guide for a disputed prediction market result explains how to frame a source-based objection. Do not confuse disagreement with an outcome with proof that the contract failed.

Summary

Expiry is normally the end of trading eligibility, not a declaration of the winner.
Read the contract-specific timeline, resolution source, fallback clauses, and dispute process.
Distinguish determination, proposed resolution, final resolution, settlement, redemption, and account credit.
Preserve timestamped rules, status, orders, fills, and positions before contacting support.
Move to payout or dispute troubleshooting only when the corresponding later state actually exists.

Frequently Asked Questions

Is an expired prediction market contract settled?

Not necessarily. Expiry can end trading while the venue still waits for designated data, determines the outcome, or completes a dispute process.

Can I place an order after the expiry time?

Normally no, although the controlling rule is the venue's market state and contract. Do not retry an order that the exchange identifies as too late or closed.

Why is my position still visible after expiry?

The position may remain until resolution and settlement or redemption. Verify fills and the market status before interpreting the visible quantity.

How long does determination take?

There is no universal duration. It depends on the designated source, contract language, corrections, exceptional clauses, and the venue's process.

Does the last market price decide the result?

No. The final trading price is not the resolution source unless the contract explicitly says otherwise.

Does expiry cancel my unfilled order?

Often the remaining order becomes canceled or expired, but verify the order ledger. A partially filled order can leave a real position even when the remainder is gone.

What if the contract is voided after expiry?

Read the contract's void or exceptional-circumstances rule and the venue's final notice. Do not assume a universal refund or fee treatment.

When should I contact support about an expired contract?

Contact support when the observed status conflicts with the documented timeline, a required transition is overdue under the actual rule, or the final ledger does not match your fills. Include a minimal timestamped evidence packet.
