Market context
Ship traffic through the Strait of Hormuz has virtually stopped, with commercial shipping suspended after a brief reopening in April 2026 that collapsed within a day. The strait remains closed, leaving near-zero transits against a normal baseline of roughly 60 vessels daily, a situation exacerbated by high tensions following US strikes on Iranian military sites and Tehran’s retaliatory actions [1][2]. This ongoing crisis has effectively halted a route carrying approximately 20% of global oil and gas, with the estimated daily economic cost exceeding $4 billion as ships reroute via the Cape of Good Hope [2][3].
Historically, similar standstills in this region have persisted for months without rapid recovery, framing the current 2% crowd-implied probability as a realistic assessment rather than an outlier. Previous closures, such as those triggered by mine-laying threats or toll impositions by the Islamic Revolutionary Guard Corps, saw traffic remain at a near-standstand for weeks before any meaningful uptick occurred [3]. The IMF Portwatch data currently shows a 7-day moving average of only 32.57 vessels as of late June, far below the 60-vessel threshold required for this market to resolve to "Yes" [7].
Traders should monitor the US naval blockade lift deadline of 19 July 2026, which is a prerequisite in the June 17 memorandum of understanding for Iran to restore traffic levels [4]. While the agreement mandates immediate commencement of commercial navigation, progress has been minimal, and President Trump has declared a blockade due to stalled peace negotiations [3]. Recent MarineTraffic data indicates a slow increase to 34 crossings yesterday, yet this remains a tiny fraction of normal volume, suggesting that a return to the 60-vessel average by 7 July is highly improbable without a sudden geopolitical breakthrough [4][9].
Methodology
This page reviews Strait of Hormuz traffic returns to normal by July 7? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
