Twelve and a half cents. That's what a permanent US-Iran peace deal by May 26, 2026 is worth on Polymarket this morning, and the number has not moved a single basis point in 24 hours despite $4.8 million in fresh volume hitting the tape. The crowd has looked at the diplomatic calendar, looked at the news, and decided the answer is no, loudly, repeatedly, and with real money.
The Flat Line Is the Story
Price stability at 12.5 cents with $It's consensus. When a market sits dead still while nearly five million dollars washes through it, what you're watching is a ceiling holding, not a floor waiting to give way. Buyers pushed, sellers pushed back, and the needle didn't move. That's a liquid market that has already priced one in and rejected it.
The full lifetime of the market tells the same story at a larger scale: 5,399,481 in total volume, with YES sitting at 12.5 cents. Roughly 31 percent of all the money ever traded on this question moved through the order book in the last 24 hours alone. The market is not quiet. The market is shouting NO, just in a very orderly way.
For context on what 12.5 cents actually means: if you bought YES at this price and a permanent peace deal somehow materialized by May 26, 2026, you'd collect .00 per share. Eight-to-one. Las Vegas would hang a neon sign over odds like that. The bettors are not taking the under because they're timid. They're taking it because the implied probability of any permanent US-Iran framework being signed, ratified, and in force within roughly a year looks, to this crowd, like a long shot that doesn't even clear 13 percent.
What the Tape Actually Shows
The five most recent trades on the Polymarket market are showing not because they're surprising, but because of how uniform they are.
May 25, 3:09 PM: a BUY on NO, 93,512 shares, $81,133 notional, at 86.8 cents per NO share.
May 25, 3:05 PM: a BUY on NO, 250,994 shares, $218,866 notional, at 87.2 cents per NO share.
May 25, 1:46 PM: a BUY on NO, 65,733 shares, $59,817 notional, at 91 cents per NO share.
May 25, 10:55 AM: a SELL on NO, 70,420 shares, $63,759 notional, at 90.5 cents.
May 24, 9:45 PM: a BUY on NO, 61,582 shares, $56,655 notional, at 92 cents per NO share.
Four buys on NO and one sale of NO. The sale was someone taking profit, not someone flipping bullish. The total notional across just these five trades: $480,272. These are not retail dabblers clicking through a mobile app. The 250,994-share buy alone, at $218,866, is a position size that requires a wallet with conviction and cash. Polymarket wallets are pseudonymous and the venue settles in USDC offshore, so the identity behind any single wallet stays opaque. But the behavior is visible: serious money, moving in one direction, repeatedly.
The NO price across these trades ranged from 86.8 cents to 92 cents, which means YES ranged from 8 cents to 13.2 cents. The market has drifted slightly YES-ward recently, which is why the 12.5-cent current price looks generous compared to the 8-cent prints from earlier in the window. That drift is probably news-driven, not structural. Every time there's a headline about diplomatic back-channels or a rumored backchannel meeting, the YES price catches a small bid and then gives it back. The pattern so far: bid, reject, fade.
What the Volume Gap Tells You
The 24-hour-to-total ratio deserves its own paragraph. $4.8 million moved in 24 hours against 5.4 million total. That's 31 percent of all lifetime volume occurring in a single day, on a market that resolves in roughly a year. When that happens, one of two things is true: either the market is experiencing a genuine new-information event that's drawing in fresh capital, or it's experiencing a high-velocity argument between the YES contingent and the NO contingent, with neither side winning.
Given that the price moved zero, 0.0 percentage points, the answer is clearly the second one. The tape is showing a sustained, expensive disagreement that's resolving in favor of NO, which is why the price hasn't ticked up despite the volume. Every time someone stepped up to buy YES, someone else was ready to sell it back at 12.5 cents or better. The liquidity pool (44,043 as of this writing) is healthy enough to absorb that trading without seizing up. The bettors are arguing loudly and the market is absorbing the argument without drama.
The Diplomatic Reality the Bettors Are Pricing
The question resolves on May 26, 2026. "Permanent peace deal" is a high bar: not a ceasefire, not a framework agreement, not a joint communique from a third-country summit. A permanent deal. Between the United States and Iran. Within roughly 12 months from now.
The historical record on US-Iran diplomacy does not exactly overflow with successful permanent agreements. The JCPOA, the closest thing to a significant diplomatic achievement in the modern era, took years of negotiation, involved six world powers, and was subsequently withdrawn from unilaterally by the United States in 2018. The current diplomatic landscape involves a US administration that has oscillated between maximum pressure and selective engagement, and an Iranian government dealing with internal economic pressure and regional proxy conflicts that don't simplify its negotiating posture.
The 12.5-cent price implies the crowd thinks there's roughly a one-in-eight chance someone threads that needle by May 26, 2026. Given the definition of "permanent" in this question, that might actually be optimistic. A ceasefire or a temporary nuclear monitoring agreement could plausibly happen. A permanent peace deal, the kind that would satisfy whatever criteria Polymarket's resolution source uses, is a different instrument entirely.
That said: It's 12.5 cents. It's calling it unlikely enough that the smart money keeps selling it back down every time a news cycle nudges it upward. Twelve and a half cents is where the pressure balances out: high enough to attract optimists, low enough that the NO-side keeps piling in.

The Structural Math
Here's a quick way to think about the money flows. At 87.5 cents (the current NO price), a $218,866 buy on NO returns $218,866 / 0.875 = roughly 250,000 shares. If the deal doesn't happen, those shares are worth .00 each at resolution: a gross return of $250,133, a profit of roughly $31,267 on an $218,866 bet. That's a 14.3 percent return if you're right. Not spectacular. But these are traders buying NO repeatedly, in size, which means they either think 12.5-cent YES is mispriced (too high), or they're hedging a position elsewhere, or both.
The 3:05 PM trade on May 25 is the one worth sitting with. $218,866 notional, 250,994 shares of NO, at 87.2 cents. That's a deliberate, sized position. Whatever wallet is behind it has done the math and decided the current YES price is still too generous.
The sell at 10:55 AM that same day ($63,759 notional, NO at 90.5 cents) is someone who bought NO cheaper, saw the price run toward 91-92 cents (YES dropping toward 8-9 cents), and took profit. Classic: buy the pessimism, sell into the pessimism rally, repeat. The market is liquid enough for that trade to work.
One More Number
5.4 million in total volume. At 12.5 cents on YES. That's a lot of money to spend confirming that people don't think this is happening.
The market resolves in roughly a year. A lot can change. Administrations pivot. Backchannel negotiations surface. Regional crises sometimes force unlikely conversations. The YES side is not wrong to keep the price above zero. But the people putting real size into NO, and the five most recent large trades are uniformly in that camp, are voting with specificity and scale.
