US-Iran talks stall as Iran dismisses US blockade

US-Iran talks have hit a wall after Iran dismissed the US blockade. The market for Trump’s Hormuz blockade announcement by May 31 sits at 63.5%, down from 72% yesterday.

Market reaction

Both the Trump’s Hormuz Blockade Announcement and US Blockade of Hormuz markets show similar declines. Odds for lifting the blockade by May 31 are at 63.5%, down from 90% a week ago. Traders are pricing in skepticism about a diplomatic breakthrough after Iran’s firm rejection of US demands and the ongoing naval blockade.

The Iran Uranium Enrichment Agreement market has fallen to 5.7% YES, down from 50% a week ago. That collapse tracks with Iran’s rejection of indirect talks and the stalled negotiations over uranium enrichment.

Why it matters

Daily USDC volume across these markets is $95,253, with order book depth of roughly $9,000 to move the price 5 percentage points. The largest move in the last 24 hours was a 5-point spike at 3:50 PM. These markets are active but thin enough that single large trades or news headlines can jolt prices.

What to watch

A YES share in the blockade market, priced at 64¢, pays $1 if resolved, for a potential 1.56x return. But the current dynamic looks more like posturing than progress. Traders will likely need concrete de-escalation signals before betting on resolution. Watch for Pentagon statements or updates from Pakistan’s mediation efforts. Any sign of direct US-Iran engagement or a shift in Trump’s rhetoric could move odds fast.
