Strait of Hormuz traffic returns to normal by July 7?

Platform comparison

Market context

The Strait of Hormuz remains fully closed after a brief, failed reopening on 21 April, leaving near-zero commercial transits against a normal baseline of roughly 60 ships daily. Over 150 vessels, including tankers and bulk carriers, are stranded while Brent crude surges and war-risk insurance premiums hit extreme levels exceeding 16 times normal rates. This 9% crowd-implied probability reflects the stark reality that the strait has been effectively halted for weeks amid the ongoing Iran conflict, with no resolution from peace negotiations and President Trump having declared a naval blockade as a prerequisite for any ceasefire.

Historical precedents show that similar closures during regional conflicts rarely resolve within months; the 2026 disruption mirrors past standstills where throughput fell below 2% of normal for extended periods, often requiring direct military de-escalation or mine-clearing operations before traffic normalised. Comparable cases suggest that without a formal ceasefire or explicit US-Iran diplomatic breakthrough, the likelihood of reaching the 60-ship threshold by July 7 remains negligible, aligning with the market’s low confidence in a rapid recovery.

Traders must monitor President Trump’s stated ceasefire prerequisites, any announcements regarding mine-clearing operations, and scheduled naval blockade adjustments. Recent reporting from NBC News confirms that Tehran has implied it may have laid mines in the strait, while Iranian media released maps indicating safe routes, yet actual transit figures remain minimal due to GPS-altering tactics by vessels. A breakthrough in US-Iran negotiations or a direct US military strike on Iranian coastal radar sites, as seen in late February, would be the primary catalysts for reopening, though current data shows no such progress.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

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