A political prediction market can look abstract until one account changes its mind in public. On Friday, a profitable Polymarket wallet bought “Yes” on a US-Iran permanent peace deal by May 31 — then, less than three hours later, bought the opposite side.
That flip is the cleanest signal in a noisy day. Across the related US-Iran peace-deal markets, bettors were not arguing about whether diplomacy matters. They were arguing about the clock.
The wallet
The account worth watching is 0x35bbbad2415fe5e39b12da9a316cdc80b022009b. It is not a random new buyer: its profile shows 244 wins and 85 losses across closed positions, with about $223k in lifetime profit. That is a 74% win rate, good enough to make its change of heart stand out.
At 13:32 UTC, the wallet bought about $7k of “Yes” on the market asking whether the US and Iran will reach a permanent peace deal by May 31. The fill was at 22¢ — in Polymarket terms, roughly a 22% chance. Then the same account sold some Yes shortly after, and by 16:25 UTC it had bought $12k of “No” at 79¢.
That is not a tiny adjustment. It is the same bettor moving from “the May deal is underappreciated” to “the May deal probably does not happen,” all on the same afternoon.
The bet
The broader event is a calendar ladder: peace deal by May 15, by May 31, by June 30, and earlier dates that have already passed. The event page has drawn nearly $68M of volume, with about $1.4M of liquidity, so this is not an obscure corner of the site.
The current odds line up the way you would expect. The May 15 contract is a long shot, around 9.5¢ on “Yes.” May 31 is higher, with Yes bids and asks around 22¢ to 23¢. June 30 is higher still, with buyers and sellers around 37¢ to 38¢.
That ladder matters because many of Friday’s bets were not simply “peace or no peace.” They were deadline bets. A wallet can believe a deal is plausible by summer while rejecting the idea that it arrives by the end of May.
What the market thinks
The May 31 market had the liveliest tug-of-war. In the last 24 hours, Data API trades in that contract showed about $28k of Yes buys from 5 wallets, against about $27k of No buys from 3 wallets. The average Yes buy was near 21¢; the average No buy was near 81¢. In plain English: both sides were willing to pay market prices, but they were arguing around a roughly one-in-five chance for a May deal.
The price action tells the same story. May 31 Yes opened the day near 18.5¢, climbed as high as 27.5¢, then faded back to about 21.5¢ by the latest history sample. June 30 Yes had a wider move, starting near 31¢, reaching 43.5¢, and ending near 37.5¢.
The order book also shows where the market is dug in. On May 31 Yes, there was a very large stack of buy orders at 20¢, while sellers were waiting from 23¢ through 25¢. On June 30 Yes, buyers were concentrated around 35¢ to 37¢, with sellers appearing from 38¢ to 40¢.
The other side
The flip was not the only notable move. A brand-new account, 0x971c0ec2bb61da6a78692a42fc1811cb2cca4887, bought nearly $20k of June 30 Yes across three trades at an average price around 33¢, then added $5k of May 31 Yes at 20¢. The alert stream marked it as only about 16 hours old by the later buy, which makes the size more interesting and the record less trustworthy.
There were also more established Yes buyers. One account with 694 wins and 152 losses, up about $630k lifetime, bought about $5k of June 30 Yes at 35¢. Another profitable geopolitics-heavy wallet bought the May 15 Yes at 9¢. These are not all the same thesis, but they rhyme: the later the deadline, the more buyers were willing to pay.
The clean watch now is the May 31 line. If that contract stays pinned near the low-20s while June 30 holds the high-30s, the market is saying “not soon, maybe later.” If the 74% wallet keeps adding No, that is a different message.
