U.S.-Iran Deal Eases Hormuz Shipping Fears as Polymarket Raises “Iran Ends Enrichment by June 30” Odds to 67.5%

Oil prices extended a pullback after the International Energy Agency projected a supply glut next year, following a U.S.-Iran deal that included commitments affecting shipping through the Strait of Hormuz. On Polymarket, traders lifted the odds to 67.5% that Iran agrees to end enrichment of uranium by June 30, up from 61.5%.

Key Takeaways

• Polymarket prices a 67.5% chance that Iran agrees to end enrichment of uranium by June 30 (Yes 67.5%, No 32.5%).
• Odds moved higher after reports tied a U.S.-Iran agreement to easing Middle East war risks and improving conditions for commercial shipping through Hormuz.
• The contract is set to resolve on June 30, 2026, giving traders a fixed deadline for any agreement on enrichment to be reflected in pricing.

Oil prices were little changed after Vice President JD Vance said tankers carrying more than 12 million barrels crossed the Strait of Hormuz overnight, which he described as a high since the start of the conflict. The report followed a deal President Donald Trump signed with Iranian President Masoud Pezeshkian aimed at ending the war in the Middle East. Under the agreement, Iran must allow ships to transit Hormuz without paying tolls for 60 days, while the U.S. lifts its naval blockade. Vance said Iran had not fired on commercial ships for a second night in a row and that U.S. forces allowed more than a dozen vessels to pass through the blockade before it ended. Ship-tracking data cited in the report indicated traffic had not yet surged, even as some tankers became visible near the Gulf of Oman and analysts said shippers remained cautious about resuming prewar transit levels.
