Iran closes Strait of Hormuz amid US-Iran tensions

Iran closed the Strait of Hormuz, and the market on no US-Iran diplomatic meeting by June 30 has moved to 3.7% YES, up from 2% yesterday.

Market reaction

Iran’s closure of the Strait, combined with the US seizure of an Iranian cargo ship, has traders betting against a diplomatic meeting. The June 30 market sits at 3.7% YES. The market is thin, with only $400 in daily USDC volume, so small orders move the price easily.

The odds of Iran surrendering its enriched uranium stockpile by April 30 dropped to 31.2% YES, down from 65% yesterday. The largest single move was a 12-point drop, showing traders doubt Iran will negotiate under these conditions.

Trump agreeing to Iranian oil sanction relief by April fell to 43.5% YES, down from 62% a day ago. Traders are reading the hardening US stance as a barrier to concessions.

Why it matters

Iran closing a waterway that handles roughly 20% of global oil transit, paired with US ship seizures, has compressed the timeline for any diplomatic resolution. At 31.2¢, a YES share on Iran surrendering its uranium stockpile by month’s end pays $1 if it resolves, a 3.2x return. But with 12 days until resolution, the price implies traders think a breakthrough is unlikely.

What to watch

Any statements from US or Iranian officials about new negotiations. A confirmed meeting at a neutral location could move the diplomatic meeting market sharply.
