Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global seaborne petroleum trade and remains the world's most critical maritime chokepoint. Transit volumes have fluctuated sharply since mid-2024 owing to regional tensions, Houthi attacks on shipping, and temporary diversions around the Cape of Good Hope. This market hinges on whether daily arrival counts—measured as a seven-day rolling average by IMF Portwatch—climb back to 60 or above by year-end 2026, a threshold that represents near-normal pre-disruption traffic patterns.

Historical precedent suggests recovery timelines depend heavily on perceived security improvements rather than physical infrastructure. Following the 2019 tanker attacks and the 2020 Soleimani assassination, transit volumes rebounded within six to nine months once shipping insurers and operators regained confidence in corridor safety. Current crowd probability of 77% reflects moderate optimism that either regional de-escalation or established alternative routing becomes sufficiently normalised that carriers resume direct transits. The 26-month settlement window provides ample time for geopolitical shifts or security arrangements to take hold.

Traders monitoring this market should track announcements from the US Fifth Fleet, Iranian statements on maritime security, and monthly Portwatch data releases. Recent reports from Lloyd's List and Splash247 indicate some carriers have already begun cautiously returning to the Strait as insurance premiums stabilise. Deposit friction remains material for active traders—SEPA transfers and Klarna's payment rails offer lower-cost entry than traditional wire methods, whilst USDC settlement reduces withdrawal delays for those managing multi-market positions across longer timeframes.

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Klarna UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
