Market context
The real-world issue is whether shipping through the Strait of Hormuz gets back to a near-normal level of about 60 daily transits on IMF PortWatch’s 7-day moving average before 15 July 2026. In practical terms, that means the market is keyed to a specific data series rather than headlines alone, so a power-user would watch the published moving average and, if automating around it, trigger on the first PortWatch reading at or above 60 rather than waiting for any later confirmation.[13]
The recent benchmark is sharply negative. Reuters reported just three commodity vessels on 17 July, the fewest daily transits since May, after renewed U.S.-Iran escalation and a resumed blockade disrupted traffic.[2] Other reporting showed counts falling from the low 20s before mid-July to single digits by 16 July, while Lloyd’s List Intelligence said non-Iranian linked transits dropped to 25 in the week 13-19 July from 108 a week earlier, with traffic down about 90% year-on-year.[1][6] Kpler has also pushed its normalisation view into early 2027, which helps explain why the crowd has priced the return-to-normal condition at 0% YES.[11]
For catalysts, the main drivers are security announcements, any pause or re-escalation in U.S.-Iran actions, and shipping-company routing decisions that feed through to AIS-based PortWatch counts. Reuters and Lloyd’s both described traffic remaining at a trickle even after a brief pause in fighting, with little evidence of a sustained rebound along the southern Omani corridor.[15][6] Programmatically, the cleanest approach is to poll IMF PortWatch, store the 7-day average as a time series, and alert on any print at or above 60, because a short-lived daily bounce is irrelevant if it does not lift the moving average past the threshold.[13]

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.
UK Frequently Asked Questions
- 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 Polymarket Bot UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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.
- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- Do I pay tax on prediction market profits in the UK?
- UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
