Postponed US-Iran talks push Polymarket to 13.5% on ending enrichment by July

U.S.-Iran Talks Postponed: Polymarket Slashes Odds Iran Ends Uranium Enrichment by July 31

U.S.-brokered talks with Iran faced renewed scrutiny after Washington and Tehran postponed discussions and both sides framed an interim agreement as conditional. The shift in tone coincided with Polymarket traders cutting the implied chance that Iran agrees to end uranium enrichment by July 31.

Key Takeaways

• Polymarket prices the “No” outcome at 86.5% and “Yes” at 13.5% for Iran ending enrichment by July 31.
• Odds fell after postponed U.S.-Iran talks and conditional messaging from U.S. and Iranian leaders raised doubts about a definitive agreement.
• The contract is set to resolve on 2026-07-31, after a 16.0 percentage-point drop in the “Yes” price over the last 24 hours.

Global markets traded weaker as investors questioned how durable a U.S.-brokered peace agreement with Iran will prove. U.S. Vice President JD Vance said any economic relief for Tehran would depend on full compliance with the interim terms, arguing the United States would not provide money absent that compliance. Iran’s Supreme Leader, Ayatollah Mojtaba Khamenei, also framed the arrangement as conditional, saying he approved a memorandum only after receiving guarantees that Iran’s rights and the “resistance front” would be safeguarded. European stocks slipped after talks between Tehran and Washington were postponed, with the pan-European Stoxx 600 down 0.2% and the FTSE 100 off 0.35%. Japan’s Nikkei ended up 0.28% at 71,250.06, while South Korea’s Kospi edged down 0.13% after crossing the 9,000 level a day earlier.

Polymarket Pricing: “Yes” at 13.5%, “No” at 86.5% as Volume Hits $521,786 and “Yes” Drops 16 Points in 24 Hours

On Polymarket, the binary contract “Iran agrees to end enrichment of uranium by July 31?” was last priced at 13.5% for Yes versus 86.5% for No, keeping No as the clear market leader. The Yes price is down 16.0 percentage points from 29.5%, according to the latest 24-hour and 7-day change readings.
