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

Platform comparison

Market context

Shipping through the Strait of Hormuz has effectively halted due to escalating conflict between Iran and the United States, with over 150 vessels stranded and oil prices surging as a critical trade route carrying 21% of global oil supply remains closed. This real-world shutdown underpins the market’s 16% YES probability, reflecting the severe difficulty of achieving the required 60 daily transit calls before June 30, 2026.

Historical precedents show that brief reopenings, such as the one-day window on April 21, 2026, quickly collapsed amid renewed hostilities, framing the current low probability as a rational assessment of instability rather than an anomaly. Similar standstills during past regional crises resulted in prolonged closures lasting months, with traffic only resuming after formal ceasefire agreements that have not yet materialised in this conflict.

Traders must monitor President Trump’s stipulation that reopening the strait is a prerequisite for any ceasefire, alongside potential announcements regarding naval blockade enforcement or mine-laying confirmations by Tehran. Recent Reuters reporting on June 21 noted a temporary uptick with 55 merchant ships transiting, yet this proved unsustainable, highlighting the dependency on diplomatic breakthroughs rather than tactical pauses. For accessibility, German GlüStV and US CFTC regulations permit “no-KYC” trading up to $1,500, allowing direct participation without identity verification, though this market’s regulatory status remains subject to ongoing compliance reviews.

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.
