Unlike traditional polls or news analysis, Polymarket Iran odds reflect actual capital at risk. Traders buy Yes or No shares that pay $1.00 if correct. Higher volume means stronger collective conviction – and right now, volumes on Iran contracts are among the highest on the entire platform. Here is the exact situation as of March 17, 2026.
Current US-Iran Ceasefire Odds on Polymarket
The defining question for many traders: when – or if – an official ceasefire between the US and Iran happens. Polymarket splits this across clear date buckets, each with its own order book and independent resolution. The spread across these timelines tells a story.
The probability curve from March (13%) to December (73%) is not just an opinion – it reflects where capital is actually moving. The $10.5M volume on the March 31 contract is the strongest signal of all: the crowd has priced out any near-term deal with overwhelming conviction. The longer the runway, the more room the market gives for diplomacy to work.
What makes this curve particularly informative for traders is the pace of change across buckets. From March to April, probability nearly triples (13% → 40%). From April to June, it adds another 18 points. This non-linear jump suggests the market sees a specific window – likely mid-Q2 2026 – as the most probable diplomatic inflection point, possibly tied to congressional sessions, back-channel talks, or military pressure timelines that informed capital is tracking.
Iranian Regime Fall Odds on Polymarket
Regime change is another high-volume Polymarket Iran odds topic. With nearly $18 million in traded volume on the June 30 contract alone, this is not a fringe market – it has become one of the most liquid geopolitical prediction contracts currently live.
Only 27% of capital thinks the current Iranian regime falls by June. The crowd still prices "No" as the clear base case through mid-year. But the 39% probability for the full-year market is not trivial – it tells you that more than a third of informed capital thinks regime-level instability is a real 2026 scenario, just unlikely within the next three months.
The $17.96M volume on the June 30 contract is the real signal here. When that much capital concentrates around a 27% probability, you are not looking at speculation. You are looking at a sophisticated pricing of tail risk by people who have studied the factors closely. A single significant escalation event – military, diplomatic, or social unrest-driven – could move this contract dramatically within hours, making it one of the highest asymmetric opportunities on the platform for traders who have a view on Iranian domestic stability.
Regime fall contracts remain cheap under 30% through June. Any surprise internal news – protests, military defections, or a leadership health development – could move these contracts from 27% to 50%+ within a single trading session. The $18M volume base means liquidity is there to exit quickly if you need to.
Crude Oil at $100 by End of March – Polymarket Odds
Geopolitics and oil prices are tightly linked in 2026, and the market for crude oil hitting $100 has drawn enormous attention as a direct proxy for Iran escalation risk. Polymarket currently prices approximately 80% Yes that the CME front-month CL contract touches $100 or higher on any trading day by March 31, 2026.
Resolution uses the official CME settlement price on any trading day. This means a single intraday touch above $100 is sufficient – the contract does not require oil to close above the level. The 80% probability reflects the crowd's near-certainty that geopolitical supply fears will push spot prices to that level before March closes.
The gap between $100 (80%) and $120 (29%) is equally informative. It tells you the crowd is not pricing in a shock event – just sustained pressure. A $120 outcome requires something new and dramatic in the next two weeks. For traders who believe Iran escalation has a tail scenario that the market underestimates, the $120 contract at 29% offers the most compressed leverage available.
What the Markets Really Think: Signal Table for Traders
These Polymarket Iran odds paint a consistent and internally coherent picture. The crowd is not panicking – it is making precise, differentiated bets across multiple correlated outcomes. Here is the full signal read across every major Iran contract right now:
| Market | Yes % | Volume | Signal | Tag |
|---|---|---|---|---|
| Ceasefire by March 31 | 13% | $10.5M | Strong No conviction. Near-term deal is priced out. | High Conf |
| Ceasefire by April 30 | 40% | $2.65M | Toss-up. Slight lean toward No but very tradeable. | Watch |
| Ceasefire by June 30 | 58% | $1.12M | Crowd sees Q2 as the most likely diplomatic window. | Lean Yes |
| Ceasefire by Dec 31 | 73% | Growing | Long-dated discount. Full-year resolution likely. | Bullish |
| Regime Fall by Jun 30 | 27% | $17.96M | Tail risk priced but not base case. Asymmetric upside. | High Vol |
| Regime Fall before 2027 | 39% | Multi-M | More than a third of capital pricing instability in 2026. | Monitor |
| Oil $100 by Mar 31 | 80% | Multi-M | Near-certain. Iran supply fears fully priced. | Strong Yes |
| Oil $120 by Mar 31 | ~29% | Multi-M | Requires shock event. High leverage if you have a view. | Speculative |
The internal consistency of this table is worth noting. The crowd is simultaneously pricing out near-term ceasefire (13%), maintaining 80% certainty on an oil spike, and holding regime fall at 27%. These positions are mutually coherent – they describe a world where tensions remain elevated for months, oil stays pressured, but outright regime collapse or full diplomatic resolution both remain minority scenarios through mid-year.
Why Polymarket Iran Odds Matter More Than Headlines
News outlets often swing wildly with each headline. Prediction markets aggregate thousands of independent, financially-incentivised bets. When volume exceeds $10M on a single outcome, the probability becomes hard to ignore as a base-rate for decision-making.
The mechanics amplify accuracy: every Polymarket trader who buys a Yes share at 27% is putting real USDC on the line, betting they can profit from the outcome. This is fundamentally different from a poll respondent clicking a radio button. The result is a continuously updated, adversarially-validated probability that incorporates satellite intelligence reports, diplomatic back-channels, military positioning data, and every other source of edge that sophisticated traders bring to the table.
Right now the data shows measured escalation pricing – not panic. The calm, graduated nature of these odds can help you position portfolios or place targeted trades before traditional markets fully react to incoming developments. When whale wallets – particularly well-funded accounts with prior winning records on Iran contracts – start moving size into specific buckets, that is worth tracking in real time. PolyMonit's live feed is built exactly for that signal.
For general Polymarket traders: oil futures and energy stocks may offer asymmetric upside aligned with the 80% oil signal. Long-dated ceasefire shares (December 31 at 73%) trade at a discount relative to near-term risk. Regime fall contracts remain under 30% through June, but any surprise news could move them fast.
