Strait of Hormuz traffic returns to normal by September 30?

Platform comparison

Market context

Shipping through the Strait of Hormuz is still being measured against a disrupted baseline, not a fully normal one, after weeks of reduced transits and repeated claims by Tehran that the waterway has been closed or reopened. Reuters reported in April that traffic was running at less than 10% of typical volumes, while CNBC cited Windward data showing only 12 vessels crossing on one Sunday in June, versus more than 21 the day before, even as Lloyd’s List said commercial shipping was still operating through the route.[6][1] That makes the market’s **22% Yes** look cautious rather than extreme: it is above a pure “tail event” price, but still well below the 51% and 68% pre-August and pre-September probabilities Bloomberg reported for a similar Kalshi contract in mid-June.[2]

Historical comparables point to slow recovery rather than a quick snap-back. The New York Times said a recent agreement called for traffic to be restored within 30 days, but that pre-war levels remained uncertain, while other reporting described shipping as still far below normal even after a ceasefire.[3][4] Analysts have framed the core issue as operational, not just political: insurers, carriers and terminal planners need confidence that the route will stay open long enough for schedules to reset. That is why a temporary easing in headlines has not automatically translated into a 7-day moving average of 60 or more arrivals, which is the threshold this contract uses.[10][3]

The main catalysts are any formal Iran-US or Iran-Israel announcements, changes to naval security posture, and carrier schedule rebuilds, because Portwatch’s 7-day average will only move up if actual counted transits rise and stay elevated. Reuters’ April coverage showed how quickly even a ceasefire can still leave traffic at a standstill, and CNBC’s June reporting showed the flow remains highly uneven week to week.[6][1] Traders should also watch whether major liner operators, tanker pools and Gulf terminal users restore routings through Hormuz rather than continuing diversions via the Cape or regional bypass pipelines, since those dependencies determine whether the count can sustainably clear the 60-transit line.[5][8]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi vs Polymarket, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
