U.S.-Iran strikes lift oil, Polymarket puts Hormuz normalization at 38.5%

Strait of Hormuz Shipping Risk: Polymarket Odds Slide After U.S.-Iran Strikes Lift Oil Prices

Oil prices rose after fresh U.S. and Iranian strikes revived doubts about a near-term normalization of shipping through the Strait of Hormuz. On Polymarket, that risk backdrop has pushed the “Strait of Hormuz traffic returns to normal by July 31?” contract down to 38.5% for Yes, with No leading at 61.5%.

Key Takeaways

• Polymarket prices “No” as the leading outcome at 61.5% versus 38.5% for “Yes.”
• Traders repriced after weekend U.S.-Iran strikes and reported vessel attacks renewed uncertainty around Strait of Hormuz shipping conditions.
• The contract resolves on July 31, 2026; Yes odds are down 3.5 percentage points over the past 24 hours.

Oil prices climbed after a renewed flare-up between the United States and Iran raised concerns about shipping conditions in the Strait of Hormuz. Brent crude rose about 0.9% on Monday, with Brent futures for August delivery at $73.21 a barrel as of 03:30 GMT, up 127 cents from the day before. U.S. Central Command said it carried out strikes against Iran on Friday and Saturday, citing Iranian attacks on two commercial vessels in the strait, a key route for roughly one-fifth of global oil and liquefied natural gas trade in peacetime. Iran responded with missiles and drones targeting U.S. military assets in Bahrain and Kuwait, while reports said the two sides agreed to halt attacks and resume negotiations. A memorandum of understanding signed on June 17 by U.S. President Donald Trump and Iranian President Masoud Pezeshkian was described as repeatedly strained by renewed hostilities and disputes over its meaning.

Polymarket Data: $10.7M Volume as “Traffic Normal by July 31?” Drops to 38.5% Yes vs 61.5% No
