Polymarket Reprices on U.S.–Iran Strike Risk, Driving “Hormuz Normal by July 31” Toward a Near-Total No

Polymarket is pricing a near-certain “No” on whether Strait of Hormuz traffic returns to normal by July 31, with No at 98.45% (Yes 1.55%) on $18.55M matched volume. The latest repricing follows renewed U.S.-Iran strikes and reported disruption risks in and around the strait, and the contract’s move shows how quickly traders have converged on a single outcome.

Key Takeaways

Polymarket’s leading call is No at 98.45% (Yes 1.55%) for “Strait of Hormuz traffic returns to normal by July 31?”
Traders leaned harder into disruption risk after reports of escalating strikes and claims of targeting tankers, pushing the market toward an extreme No consensus.
The market resolves on 2026-07-31 (UTC), and pricing has swung sharply over the past week (historical_summary: change_7d 35.5pp, high volatility, reversal detected).

A report describes a fresh round of U.S. airstrikes against Iran after another U.S. service member’s death, followed by Iranian retaliation targeting Bahrain. It also says shipping traffic in the Strait of Hormuz has largely stalled, a ship caught fire near Oman, and Iran’s Revolutionary Guard claimed it was targeting tankers in the strait.

Odds, Volume, and Volatility: No 98.45% vs Yes 1.55% on $18.55M Matched as the Market Swings 35.5pp in 7 Days

This is a binary Polymarket contract: buying Yes only pays if the market’s resolution criteria judge that Strait of Hormuz traffic has returned to “normal” by 2026-07-31, while No pays otherwise; at 1.55% Yes, traders are treating a “normal by deadline” outcome as a long shot. The current split (Yes 1.55% / No 98.45%) also reflects unusually tight agreement for an event-driven market, even as the contract has seen large swings earlier (historical_summary shows high volatility and reversal_detected true). The tape implies a sharp derisking into the negative outcome: the snapshot shows Yes at 42.0 previously while the headline state now sits at 1.55% Yes, alongside $18.55M in matched volume, suggesting conviction rather than a 50/50 standoff. Versus slower narrative-driven forecasts, the market is continuously translating each incremental disruption headline into a single probability that must clear a hard calendar cutoff on July 31.

Watch whether the market continues to compress near 100% No or reopens meaningful two-way pricing; any sustained move up in Yes from 1.55% would signal traders assigning a materially higher chance of normalization before the July 31 resolution date.

Beyond the main Strait of Hormuz timing trade, Polymarket participants are also triangulating the broader risk backdrop through adjacent contracts that can move in tandem with shipping and energy headlines. In the conflict calendar lane, 99.7% is on “Israel x Iran ceasefire continues through...?” (July 18) on $692,578 volume, while longer-horizon regime and escalation questions are concentrated in “Iran leader end of 2026?” at 73.45% (Mojtaba Khamenei) with $32,663,632 and “Will the U.S. invade Iran before 2027?” at 69.5% (No) with $44,980,250. Traders looking for a cleaner extension read can also compare the later-dated “Strait of Hormuz traffic returns to normal by August 31?” at 86.5% (No) on $1,246,012, alongside the more two-sided “Iran full airspace closure by...?” at 50.5% (August 31) with $4,681,646.
