Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

Ships are currently barred from passing the Strait of Hormuz, with commercial traffic virtually shut off amid escalating tensions between Washington and Tehran. The region remains a strategic chokepoint where approximately 21% of the world’s oil supply and 25% of global LNG trade face risk, while the Strait was briefly reopened on 21 April 2026 before closing again the next day[2]. Current data shows daily transit calls at just 5.00 on 21 June 2026, with a seven-day moving average of 13.14, far below the 60-ships threshold required for this market to resolve as “Yes”[7].

Historical precedents in prediction markets often mirror voting mechanics where jury and public splits create divergence, much like Eurovision’s 50/50 jury-televote system or the Oscars’ preferential ballot for Best Picture. In this case, the crowd-implied 89% YES probability suggests strong confidence in a peace deal, yet recent precedent shows that diplomatic progress has not restored normal activity; Strait of Hormuz traffic remains below normal despite such efforts[4]. The cultural narrative momentum leans toward a ceasefire prerequisite, as President Trump has stipulated that reopening the Strait is essential for any agreement with Tehran[3].

Traders should monitor scheduled announcements from IMF PortWatch, peace negotiation outcomes, and any naval blockade declarations, as these are critical dependencies for traffic recovery. A recent NBC News report confirms that minimal progress in peace talks has led Trump to declare a naval blockade against Iran, further complicating the route’s reopening[3]. Additionally, watch for reports on mine-laying activities by Tehran, which could delay safe passage, and track whether ships begin rerouting via the Cape of Good Hope, adding up to 14 extra transit days and increasing costs[2].

Methodology

We track Strait of Hormuz traffic returns to normal by December 31? 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.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
