Strait of Hormuz traffic returns to normal by end of June?

Platform comparison

Market context

The Strait of Hormuz continues operating below pre-disruption transit volumes, with recent shipping data showing no material shift in the past 48 hours. The waterway, through which roughly one-third of global seaborne oil passes, has seen sustained pressure from regional tensions, drone and missile attacks on commercial vessels, and insurance premium spikes that have diverted some traffic to longer alternative routes. Current 7-day moving averages remain in the low-to-mid 40s for daily transit calls—well below the 60-call threshold required for market resolution.

Historical precedent suggests recovery to normal traffic levels requires either a decisive security intervention or a fundamental de-escalation in regional hostilities. The 2019 tanker attacks saw transit volumes recover within weeks once military escorts and insurance clarity emerged; the 2022 Ukraine-related disruptions to global shipping normalised over months as alternative supply chains stabilised. The 9% implied probability reflects the market's assessment that 18 months is insufficient time for such normalisation given current geopolitical entrenchment and the absence of credible diplomatic off-ramps.

Traders should monitor announcements from the US Central Command regarding naval deployments, any shifts in Iranian or Houthi messaging around maritime operations, and quarterly shipping reports from major port authorities. The International Maritime Organization's latest guidance on Hormuz transits, updated in late 2025, remains cautious. A sustained period of zero security incidents combined with explicit ceasefire agreements would be the primary catalyst; absent those, alternative routing and insurance costs are likely to remain elevated through mid-2026.

Methodology

We track Strait of Hormuz traffic returns to normal by end of June? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
