The market still prices "yes" near 98 cents, implying traders expect the ceasefire to be judged intact. The rest of the ladder rose 3 to 6 points at the front even after President Trump said the U.S. "may do it a little bit further" in Iran.
Polymarket's contract on whether the U.S.-Iran ceasefire would hold through Oct. 22 reached its deadline at 11:59 p.m. Iran time, about 4:29 p.m. Eastern on Thursday. Twelve hours later it had not settled.
At 4:42 a.m. Eastern on Friday, Polymarket's market data showed the contract still open, with its resolution status marked "disputed." "Yes" shares, which pay $1 if the ceasefire is judged to have held, traded at about 98 cents. Earlier contracts in the same series settled within about a day of their deadlines.
Who challenged the proposed outcome, and on what grounds, has not been made public. Polymarket contracts are settled through UMA, a decentralized oracle in which a proposed result can be disputed and then put to a vote of token holders. A dispute is part of that process, not a malfunction, and it can be routine.
The question underneath
Only a qualifying U.S. strike on Iranian soil before the deadline turns the contract to "no," and the resolver leans on official government statements plus a consensus of credible reporting. That makes the Oct. 21 blasts near Sirik the most obvious open question. An Israeli television report and an open-source account attributed them to U.S. strikes; U.S. Central Command has still not confirmed a strike there. Whether the dispute concerns Sirik has not been disclosed. A 98-cent price says traders expect the "yes" outcome to survive whatever the challenge is.
The rest of the ladder firmed
Contracts with later deadlines rose. The Oct. 24 contract climbed to 92.5 cents from 86.5 cents at midday Thursday. The Oct. 28 contract rose to 82.5 cents from 79.5 cents, and the Oct. 31 contract to 77.5 cents from 73.5 cents. Expiries from Nov. 8 through Dec. 31 were within about a point of where they started, with the Nov. 30 contract at 37.5 cents and the year-end contract at 28.5 cents. Across the ladder, about $1.27 million changed hands over 24 hours.
Washington's signals pointed in two directions. Before leaving for Iowa on Thursday, Trump told reporters that the U.S. had "knocked the hell out of them, and we may do it a little bit further." On Wednesday night he had said the U.S. was "not negotiating" with Iran. But the White House also said on Thursday that the U.S. "will not be attacking Iran at any time prior to the midterm elections," ABC News reported. Every October contract settles before the Nov. 3 vote.
The timing does not tie the gains to any single statement. Most of the Oct. 24 contract's gain, to 91 cents, had already happened by 3 p.m., before Trump's comments were widely reported. Time decay is a plausible contributor at the front: with fewer days left before each deadline, there is less time for a qualifying strike. The White House statement gives traders a stated reason to price the October expiries high, though prices beyond the election, from 59.5 cents for Nov. 8 down to 28.5 cents for year-end, show they still see meaningful risk after the vote.
Brent crude was about flat near $113.40 a barrel early Friday, after rising 4% on Thursday to its highest close since May.
What to watch
The UMA vote and final settlement of the Oct. 22 contract, the Oct. 24 expiry, and any U.S. or Iranian official account of what happened at Sirik. An official confirmation of a U.S. strike before Oct. 22 would put every open contract in the series under pressure.
