US Navy seizes Iranian ship in Gulf of Oman, complicating ceasefire prospects

The US Navy seized an Iranian ship in the Gulf of Oman, and ceasefire-by-April-30 odds have dropped to 37.5% YES, down from 59% just 24 hours ago.

## Market reaction

The April 30 contract is the only active sub-market, with 12 days left to resolve. The 21.5-point drop in a single day suggests traders see little path to a quick resolution. Daily volume is $80,435 in USDC, but it only takes $1,566 to move the price 5 points, so the market is sensitive to large orders.

Separately, diplomatic meeting odds for June 30 have shifted. The probability of no qualifying talks by end of June is at 3.7% YES, up from 2% a day ago. Liquidity there is thin at $400 in daily USDC volume, meaning a few large orders could move the price substantially.

## Why it matters

The seizure makes a diplomatic resolution harder to reach in the near term. A YES share on ceasefire by April 30 at 35.5¢ pays $1 if it resolves, a 2.63x return. With only 12 days until resolution, that price reflects a bet on a rapid diplomatic turnaround that current events make unlikely.

## What to watch

Official statements from CENTCOM or the Iranian government, and any intermediary activity from Oman or Qatar. Any sign of resumed talks could swing the ceasefire market sharply upward.
