Strait of Hormuz traffic returns to normal by July 31?

Platform comparison

Market context

The Strait of Hormuz remains effectively closed, with daily transit calls hovering near single digits instead of the normal baseline of roughly 60 ships. For the market to resolve "Yes" by 31 July, the IMF Portwatch 7-day moving average must surge from its current level of approximately 13 to at least 60 within just 33 days. This requires an immediate, sustained jump in daily traffic to 70–100+ vessels, a mechanical impossibility given the lagging nature of a 7-day average and the ongoing US naval blockade alongside Iranian restrictions that have kept commercial shipping suspended since the brief reopening on 21 April failed.

Historical precedents and parallel markets frame this 42% probability as overly optimistic; similar contracts on Kalshi for a return to normal flow before January 2027 show a 66% chance of failure, with odds for an August return plummeting from 66% to 21% in just two weeks. The sheer difficulty of lifting a lagging average from single digits to over 60 in under two weeks makes the outcome highly improbable, even if backlogged ships rush through or AIS broadcasting normalises rapidly. On Polymarket, this contract trades on USDC via the Polygon network using conditional tokens, where the price reflects the mechanical hurdle rather than abstract geopolitical hope.

Traders should monitor the Strait of Hormuz Live Tracker for any official reopening announcements or shifts in tanker spot rates, which have tripled for Gulf-to-Asia routes due to rerouting via the Cape of Good Hope. The daily economic cost of this closure exceeds $4 billion, affecting 21% of global oil supply and 25% of LNG trade, yet no credible schedule suggests a rapid return to normalcy. With 150+ vessels stranded and commercial shipping suspended, the catalysts required to hit the 60-ship threshold remain absent, leaving the market exposed to the high likelihood of a "No" resolution.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
