Market context
Polymarket is pricing this at **0% YES**, which means the contract is effectively treated as dead unless there is a fresh, public US announcement that offensive operations against Iran have been terminated, suspended or otherwise halted again before 31 August 2026. On Polymarket, that means the USDC-settled conditional tokens on Polygon would only pay out if the official wording clearly fits the market’s trigger, rather than a vague de-escalation or a defensive-only posture.
That 0% reading sits against a recent pattern in which Washington has already used pause language around Iran. Reuters reported on 26 July that a senior Iranian official said Iran would halt attacks while the US maintained its latest pause on air strikes, and Mike Waltz separately said on Fox News that Trump had paused US attacks to allow more diplomacy.[1] Reuters and other outlets have also described earlier stop-start pauses and ceasefires this year, including reporting that the US military halted offensive operations and later that offensive actions were suspended following a presidential announcement.[2][6][7] For a trader, the key point is that the market appears to distinguish between a temporary pause and a formal announcement ending offensive operations, so precedent cuts both ways: there is a documented language trail for halts, but also repeated re-escalation risk.
The catalysts to watch are the White House, Pentagon, CENTCOM and any direct presidential statement, especially if it uses terms such as “halt”, “cease”, “suspend”, or “terminate” in relation to offensive action. Reuters’ latest dispatch suggests diplomacy is still being used to justify the pause, which means a reversal could come through either a renewed strike order or an official clarification narrowing the scope of the current pause.[1] Any scheduled talks, maritime-security developments in the Strait of Hormuz, or changes to the ceasefire framework would matter because the market only resolves on a public and official US announcement, not on battlefield calm alone.[1][13]

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
