Israel x Hamas ceasefire cancelled by December 31: the evidence and conditions to watch

What this event actually asks

The useful question is precise: Israel x Hamas ceasefire cancelled by December 31? In the API observation at 09:57 UTC on 2026-10-04, the selected contract’s first listed outcome was priced at 5.5%. The parent event had recorded $4,067,738 in cumulative volume. This is turnover across the event, not a count of independent forecasters or proof that this outcome is correctly priced. ^[1][2]

The Yes condition is that a either Israel or Hamas announce the cancellation of the ongoing ceasefire, or if convergent reliable reporting confirms that the ceasefire is no longer in effect, by December 31, 2026, 11:59 PM ET. ^[2]

A promise to stop fighting is only one stage

The ICRC distinguishes an end to active fighting from a stable end to an armed conflict. It notes that a peace treaty does not automatically establish that military operations have actually ended. ^[3]

Negotiators may agree on a statement before commanders can enforce it everywhere. Monitoring, the treatment of alleged violations and the sequence of withdrawals can therefore matter as much as the announcement. This is an interpretation of implementation risk, not a claim that any party has secretly decided to break an agreement.

Which evidence would change the assessment?

Matching public commitments from the required parties, followed by the specific agreement or uninterrupted implementation test in the rules, would support the positive outcome.

A unilateral announcement, a limited humanitarian pause, or an unverified assertion of compliance may fall short. Conversely, an isolated violation is not automatically cancellation unless the rules define it that way.

Check whether a new report changes the evidence for the specified condition or merely repeats an existing claim. A price move can identify a question worth investigating without establishing its cause.

The next useful checkpoint

Written-rule date: December 31, 2026; 11:59 PM (ET). The selected contract and any reporting grace period govern settlement. ^[2]

Our reading is conditional: compare the next primary record with the exact threshold above, then revisit the case if the evidence contradicts it. A high quoted chance does not establish certainty; a low quote does not make the event impossible. The value of the article is a clearer test of the claim, not an asserted trading advantage.
