Ceasefire in Name Only: Three Numbers That Define the Iran Endgame

Ceasefire in Name Only: Three Numbers That Define the Iran Endgame

Three contract prices tell the entire US-Iran story heading into the final week of April. Trump extended the ceasefire Tuesday without a deadline -- but Iran attacked three ships in the Strait of Hormuz hours later, Vance's Pakistan talks collapsed, and the US blockade stays in place.

Today's Prediction Market Odds


Top Contracts to Watch

1. US Forces Seize Another Oil Tanker by April 30 -- 99.95% Yes ( Polymarket)
$2.37M in 24h volume. On April 20, US Central Command fired on the Iranian-flagged M/V Touska -- the Navy's first direct engagement with an Iranian vessel since the blockade began. Six days remain. Markets see near-zero chance the US stands down. For energy traders: crude volatility premium stays bid.

2. US x Iran Permanent Peace Deal by April 30 -- 4.5% Yes ( Polymarket)
$11.9M cumulative volume -- the single most-traded Iran contract. At 4.5%, the market says a deal is possible but a long shot. The Polymarket multi-market on Iranian demands gives texture: unfreezing assets at 44%, oil sanctions relief at 36%, uranium enrichment at 24%, Hormuz transit fees at just 8%. The market expects assets as the most likely concession, not the blockade.

3. Strait of Hormuz Traffic Returns to Normal by April 30 -- 2.85% Yes ( Polymarket)
$26M cumulative volume -- the largest of the group. Was trading near 39% in late March. Has since collapsed to 2.85% as Iran fired on a container ship Wednesday causing "heavy damage to the bridge," per UKMTO. Hormuz near-zero means the ~$26B/day in oil that normally transits stays rerouted through at least May. Physical crude spreads and tanker rates stay wide.

What to Watch Into April 30

All three contracts expire by April 30. The key variable: does Iran submit the "unified proposal" Trump requested? If yes, peace deal odds could spike sharply from 4.5%. If no, the tanker seizure resolves YES and Hormuz closes near zero. Prediction markets are pricing continued standoff -- oil volatility hedges remain bid.
