Polymarket odds sink as Hormuz July 31 normalization seen unlikely

Polymarket Slashes “Hormuz Traffic Normalizes by July 31” Odds After Fresh US–Iran Attack Headlines

On Polymarket, traders are pricing the “Strait of Hormuz traffic returns to normal by July 31?” contract as an overwhelming No, with No at 98.75% and Yes at 1.25% on $18,958,062 matched. The trigger is fresh reporting about continued declines in vessel crossings tied to new US–Iran attacks, and the lens here is how sharply odds moved versus recent history.

Key Takeaways

Polymarket’s leading outcome is No at 98.75% (Yes 1.25%) for traffic returning to normal by July 31.
After the latest catalyst, pricing implies traders see normalization by the deadline as very unlikely, despite earlier odds around 42% in the dataset’s latest historical point.
The market resolves on 2026-07-31, so the key question is whether conditions meet “returns to normal” by that date.

A report titled “Strait of Hormuz vessel crossings extend slide on fresh US-Iran attacks” says crossings kept falling and links the continued deterioration to new US–Iran attacks, adding a near-term catalyst for traders focused on shipping flow through the chokepoint.

Odds Breakdown: Yes Crashes 42% → 1.25% as $18.96M Matched Liquidity Crowds Into “No” at 98.75%

This is a binary Polymarket contract: buying Yes is a bet the market’s resolution source will deem traffic “returned to normal” by 2026-07-31, while buying No is the opposite—today’s tape heavily favors No at 98.75% versus Yes at 1.25%. The jump from a prior 42.0% reading to 1.25% Yes (a 40.75 percentage-point drop in the displayed odds) shows an aggressive repricing toward deadline failure, consistent with a market that has moved from debate to near-consensus. Liquidity is not thin: $18,958,062 matched suggests the price is not a one-off print, but a crowded view that the deadline is the binding constraint. The historical summary flags high volatility and a reversal_detected signal alongside strong bearish momentum and weakening consensus, which fits a path where the market chopped around the 50–60% zone in earlier points before breaking decisively toward “No.”

Watch whether the Yes price stabilizes above 1.25% or keeps compressing toward zero as July 31 approaches; if the market is truly in a reversal regime with high volatility, the tell will be any sustained rebound in Yes odds on comparable volume rather than brief spikes.

Cross-Contract Watchlist: How Hormuz Shipping Risk Can Spill Into Polymarket Macro & Crypto Markets Traders Track

Beyond this shipping-risk tape, traders often sanity-check their view against adjacent Polymarket contracts that can move on the same headlines and risk-on/risk-off pulses. Right now, the bigger liquidity hubs include 74.5% No in “Will the U.S. invade Iran before 2027?” on $45,830,903 matched, and 76.15% on “Iran leader end of 2026?” (Mojtaba Khamenei) with $33,239,255 matched. For shorter-dated positioning, markets like “Iran full airspace closure by...?” (46.0% on August 31) and “US x Iran Effective Ceasefire by...? (2 week pause)” (51.5% on August 31) give a cleaner read on near-term de-escalation vs. disruption probabilities that can spill into macro and crypto sentiment on the platform.
