Market context
The United States has never formally charged transit fees or protection tolls for passage through the Strait of Hormuz, despite controlling significant naval assets in the region and bearing substantial costs for freedom-of-navigation operations. The strait remains one of the world's most critical chokepoints, with roughly 21% of global petroleum passing through annually. Any US fee scheme would represent a departure from decades of post-war policy, wherein American security guarantees to Gulf allies—particularly Saudi Arabia and the UAE—have been extended without explicit per-vessel charges. The 11% implied probability reflects scepticism that such a reversal occurs within the next two years, though geopolitical and fiscal pressures have intensified debate around cost-sharing.
Historical precedent offers limited guidance. The US has never successfully implemented unilateral tolls on international straits; the 1982 UN Convention on the Law of the Sea explicitly prohibits transit fees in straits used for international navigation. However, the Trump administration's 2020 rhetoric around "making countries pay" for US military presence, combined with recent congressional proposals to recover costs from allied nations, suggests the political appetite exists. Any formal scheme would likely require either a legislative act or a creative reframing as a "protection contract" with individual nations rather than a universal toll.
Traders should monitor statements from the State Department, Department of Defence, and Congress regarding Gulf cost-sharing arrangements. Recent tensions with Iran, fluctuations in oil prices (which affect shipping volumes and geopolitical leverage), and announcements of new bilateral defence agreements with Gulf states will signal whether the administration is moving toward fee collection. The settlement window extends to end-2026, capturing potential policy shifts across the remainder of the current US administration's term.
Methodology
This page reads US charges Hormuz fees by 2026? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
