The Ceasefire Curve: 2pct Peace by Next Week, 60pct by Summer -- What Prediction Markets Say Ab

The Ceasefire Curve: Prediction Markets Price a Long War but Eventual Peace

Forget the headline odds for a moment. The most revealing prediction market data right now isn't a single contract -- it's the full term structure of ceasefire probabilities. And what it tells us about the expected duration of the US-Iran conflict is striking.

While Trump told the nation last night the war is "nearing completion" and promised 2-3 more weeks of intensified strikes, the crowd disagrees. The ceasefire probability curve prices in a long grind before any deal materializes.

Today's Prediction Market Snapshot


The Ceasefire Term Structure -- A Timeline of Peace Expectations

Polymarket's ceasefire series tells the story through cold probability:

• By April 7 (5 days): 2% -- ( Polymarket) The market gives near-zero chance of a deal in the next week. Iran's foreign ministry dismissed Trump's speech outright, saying they "will not tolerate this vicious cycle of war, negotiations and ceasefire."
• By April 15 (13 days): 9% -- Even Trump's own 2-3 week timeline for wrapping up military operations doesn't convince bettors that a formal ceasefire follows.
• By April 30 (28 days): 24% -- ($9.4M volume) Roughly one-in-four odds. This is where the curve starts to show some real probability mass.
• By May 31 (59 days): 47% -- Nearly a coin flip. The market's median expectation for ceasefire timing appears to fall somewhere around late May to early June.
• By June 30 (89 days): 60% -- Majority probability. If you're trading the summer delivery months, this is the implied baseline for supply normalization.
• By December 31: 72% -- ($82.5M total series volume) Even by year-end, there's still a 28% chance this conflict drags on.

What the curve shape tells us: The steepest part of the probability gain is between April 15 (9%) and May 31 (47%) -- a 38 percentage point jump in roughly 6 weeks. That's where the market concentrates its expectation of resolution. Before that window, almost no one expects a deal. After it, odds flatten. Traders pricing crude oil and energy derivatives should note this implied timeline sits well beyond Trump's stated schedule.

Ground Invasion vs. Ceasefire -- The Asymmetry

Here's the disconnect that matters for risk pricing:

• US forces enter Iran by April 30: 62% Yes -- ( Polymarket) ($19M volume, $101M series total)
• Ceasefire by April 30: 24% Yes
• Iranian regime fall by April 30: 3.25% Yes -- ( Polymarket) ($18.4M volume)

The market says: ground troops go in (62%), no deal gets done this month (76% no-ceasefire), and the regime survives (97%). This combination implies an extended military engagement without a clear political resolution -- the scenario most corrosive to energy markets and risk assets.

Trump's address last night didn't move the needle. Analysts called the speech "a repetition of everything he had said," and Trita Parsi of the Quincy Institute noted it "reveals that he really does not have a plan." Iran responded by continuing strikes across the Persian Gulf today.

The Economic Risk Stack

The war probability curve doesn't exist in isolation. Prediction markets are also flashing amber on the broader economy:

• US Recession Odds: ~40% -- (Kalshi) Doubled from 20% in just weeks. Oil above $100, Strait of Hormuz disruptions, and consumer spending softening are all feeding this repricing.
• Trump Orders Tariffs in April: 28% Yes -- ( Robinhood) Additional tariff action during an active war and energy crisis would compound the stagflation trade.

For futures traders, the prediction market consensus is becoming clearer: the war continues through spring, recession risk is real and rising, and policy uncertainty (tariffs, Fed response) adds another layer of volatility on top.

What to Watch This Week

• April 7 ceasefire expiry -- Currently 2%, any diplomatic signal could spike this rapidly. Watch for Witkoff shuttle diplomacy headlines.
• Oil above $105 -- If WTI stays above this level into next week, the April 30 ceasefire contract should see heavier volume as hedgers use it for duration estimates.
• Iran Gulf strikes -- Iran continued targeting Gulf assets today despite Trump's warning. Escalation vs. exhaustion will drive the short-dated contracts.
• CME Event Contracts -- CME passed 100 million event contracts traded in February and continues expanding into sports, weather, and economic events. While their geopolitical offerings are more limited than Polymarket, the regulated venue matters for institutional access.
