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

Platform comparison

Market context

The key real-world event is the reopening of the Strait of Hormuz after the US–Iran ceasefire deal, which has already prompted reports of some vessel traffic returning. Reuters-style coverage and market data have framed the move as an initial rebound rather than an immediate full normalisation, with traders watching whether the 7-day average can climb back to the IMF PortWatch threshold before month-end.[1][5]

For probability-reading, the closest analogue is a conflict-driven shipping shock followed by a negotiated reopening: traffic can rise quickly at first, but reaching a sustained “normal” level usually depends on whether insurers, naval escorts, and shipping lines all re-engage at the same pace. Bloomberg noted on 16 June that Kalshi was pricing a 51% chance of normal traffic by 1 August and 68% by 1 September, which puts a 30 June settlement window much closer to an event-risk trade than a broad recovery bet.[6] With the current crowd-implied probability at 10% YES, the market is leaning towards the view that the backlog and operational frictions will keep the 7-day average below 60 for most, if not all, of the remaining month.[5][6]

The main catalyst to watch is implementation, not rhetoric: any formal signing, military stand-down, or shipping-security announcement could accelerate transits, while delays in mine clearance, insurance cover, or convoy arrangements could leave the average subdued. CNBC reported on 15 June that traders lifted odds after Donald Trump said the strait would reopen and that increased traffic had already been seen in the previous 24 hours, but that was still accompanied by uncertainty over the details and timing of the agreement.[1] For this market, the decisive signal is whether IMF PortWatch starts publishing repeated 7-day averages at or above 60, not just isolated daily spikes.[3]

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Strait of Hormuz traffic returns to normal by end of June? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.
