Strait of Hormuz traffic returns to normal by June 15?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil passes, has experienced significant disruption since late 2023 following attacks on commercial shipping attributed to Houthi forces. Transit volumes have declined sharply from historical norms, with seven-day moving averages of daily arrivals dropping well below the 60-call threshold required for market resolution. Recovery to pre-disruption levels would require sustained de-escalation of regional tensions and restoration of confidence among shipping operators willing to transit the waterway without additional insurance premiums or rerouting costs.

Historical precedent suggests recovery timelines vary considerably depending on conflict resolution mechanisms. The 2019 tanker attacks saw shipping activity resume within weeks once military escorts and air defence systems were deployed. However, the current situation differs materially: Houthi operations have persisted for over two years with no negotiated settlement, and shipping companies have invested in alternative routes around the Cape of Good Hope. Even if attacks cease, psychological recovery and route-switching inertia typically extend normalisation beyond the immediate security improvement.

The market's 9% implied probability reflects consensus scepticism about achieving 60 daily transits by mid-June 2026. Traders should monitor ceasefire announcements from Yemen peace negotiations, statements from major shipping insurers regarding premium adjustments, and IMF Portwatch data releases for trend acceleration. Recent reports from the International Maritime Organization indicate some recovery from 2024 lows, though volumes remain 30–40% below historical baselines. Any formal agreement between Houthi leadership and regional powers would likely trigger rapid repricing across prediction markets, though execution risk remains substantial.

Methodology

We track Strait of Hormuz traffic returns to normal by June 15? 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.
