The contract on the U.S.-Iran ceasefire holding through Oct. 22 resolved about three days after its deadline, following seven proposed outcomes and six disputes. The rest of the ladder barely moved as regional delegations met in Tehran.
The most contested contract in Polymarket's Iran ladder is finally closed.
The market on whether the U.S.-Iran ceasefire would continue through Oct. 22 closed at 10:44 p.m. Eastern on Sunday and resolved "Yes." Its settlement came after 13 status entries in the oracle process that settles Polymarket's contracts: seven proposed outcomes and six disputes. The contract traded about $3.86 million over its life.
The answer itself was never much in doubt. The contract had traded at 99.75 cents before it closed, and no qualifying U.S. strike on Iranian territory has been confirmed. What took time was the process, about three days past the deadline.
The next one in line
The Oct. 24 contract has not settled. It traded at 99.45 cents at 1:46 p.m. on Monday, about two days after its deadline, with the market again pricing near-certainty of "Yes" while the formal process runs.
Neither Polymarket nor the oracle has said publicly who proposed or disputed the Oct. 22 resolution, or why. For traders, the practical lesson is that capital in an expired contract can stay tied up for days, even when the outcome looks settled.
A quiet ladder during the talks
The live contracts barely moved on Monday as senior officials from Saudi Arabia, Pakistan and Turkey met Iranian leaders in Tehran. The Oct. 28 contract rose to 94.5 cents from 93.5 cents, and the Oct. 31 contract to 86.5 cents from 85.5 cents. The Nov. 8 contract was at 66.5 cents, and the Nov. 15 contract rose 4 points to 53.5 cents on thin volume.
That quiet followed a jolt. On Sunday evening, the Oct. 31 contract fell as low as 69 cents in about 20 minutes before recovering most of it within minutes and all of it by Monday morning. No cause for that move has been established, and a claim of a strike at Sirik that circulated afterward remains unconfirmed by any government.
At Monday's prices, the ladder implies roughly a 5.5% chance of a qualifying strike by Oct. 28, about 13.5% by Oct. 31, about 33.5% by Nov. 8 and about 46.5% by Nov. 15. The risk is still concentrated in November.
Two readings
One reading is that the resolution shows the system working. Disputes were raised and answered, the contract settled on the outcome its price had implied, and the talks in Tehran kept the near-term contracts steady.
The other is that 13 status changes for a contract trading at nearly 100 cents is a cost the price does not show. Investors in event contracts carry settlement risk as well as event risk, and that risk is highest exactly when real-world facts are disputed.
What to watch
Settlement of the Oct. 24 contract, the Oct. 28 expiry, any outcome from the Tehran talks, President Donald Trump's decision on whether to "make a deal," Israel's election on Tuesday and the U.S. midterms on Nov. 3.
