Trump Kharg Island remarks hit Hormuz outlook as Polymarket Yes sinks to 4.5%

Trump Cites Kharg Island Attack, Blockade Threat — Polymarket Shifts to “No” on Strait of Hormuz Normalization by July 3

Comments attributed to Donald Trump about a U.S. attack on Iran’s Kharg Island and a possible reinstatement of a blockade of Iranian ports are being reflected in Polymarket pricing on whether Strait of Hormuz traffic returns to normal by July 31. The contract’s odds have shifted sharply toward a “No” outcome as traders weigh renewed disruption risk.

Key Takeaways

• Polymarket prices a 95.5% chance that Strait of Hormuz traffic does not return to normal by July 31, versus 4.5% for “Yes.”
• The market repriced after a report citing Trump saying the U.S. attacked Kharg Island and may reinstate a blockade of Iranian ports.
• The contract is set to resolve on July 31, 2026, and “Yes” odds are down 37.5 percentage points to 4.5% from 42.0%.

A report cited Donald Trump saying the United States attacked Iran’s Kharg Island the prior night. The report also said Trump raised the prospect that Washington could reinstate a blockade of Iranian ports. The comments pointed to a possible escalation affecting maritime activity tied to Iranian exports. The report framed the statements as a signal of potential new restrictions on shipping access. The developments come as traders monitor risks to regional sea lanes connected to the Strait of Hormuz.

Polymarket Odds and Volume: “No” at 95.5%, “Yes” at 4.5% After 37.5-Point Swing on $13.33M Traded

On Polymarket, the “Strait of Hormuz traffic returns to normal by July 31?” contract is trading at 4.5% for Yes and 95.5% for No, making No the clear leading outcome. The market has seen about $13.33 million in volume, with pricing implying traders see normalization by the July 31, 2026 resolution date as a low-probability scenario. The current odds reflect a steep drop in Yes pricing from a previous 42.0%, a 37.5 percentage-point swing toward No.

Whether the Yes price can recover from 4.5% will likely hinge on subsequent trade flow signals ahead of the July 31, 2026 resolution date and any further repricing in the implied probabilities.

Traders are also tracking diplomacy timelines, with 36.5% on a “US-Iran Final Nuclear Deal by…?” resolving on December 31, and 32.0% pointing to August 15 as the leading outcome in “Iran announces withdrawal from MOU negotiations by…?”.
