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 oil passes daily, has seen transit traffic decline significantly from historical norms. The 7-day moving average of ship arrivals currently sits well below the 60-call threshold required for resolution. Polymarket prices YES at 17%, reflecting the market's assessment that normalisation within eighteen months remains unlikely given persistent regional tensions and shipping route diversification that has accelerated since 2023.

Historical precedent suggests recovery to pre-disruption baselines takes considerable time. The 2019 tanker attacks and subsequent Houthi-related incidents in 2024 both triggered sustained rerouting through the Cape of Good Hope, with shipping companies absorbing additional costs rather than risk the Strait. Even when immediate security concerns ease, vessel operators maintain alternative logistics networks for months before consolidating back through Hormuz. The current probability reflects this structural stickiness—traders are pricing in that even if geopolitical conditions improve, commercial inertia alone makes a return to 60+ daily transits by mid-June 2026 a low-probability event.

Watch for Iranian nuclear negotiations, which could shift regional risk assessments overnight, and any major shipping announcements regarding permanent rerouting infrastructure investments. The IMF Portwatch data feed itself carries operational risk; delays or methodology changes could affect settlement timing. Recent reporting from maritime intelligence firms indicates some container lines have begun shifting back towards the Strait as insurance premiums normalised through late 2025, though volumes remain fragmented. Any significant geopolitical de-escalation announcement would likely move the conditional token price sharply upward on Polygon, though the underlying event probability would need sustained momentum to reach resolution.

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.
