Strait of Hormuz traffic returns to normal by July 15?

Platform comparison

Market context

Traffic through the Strait of Hormuz remains effectively closed, with commercial shipping suspended after a brief reopening in mid-June. Pre-war levels saw 130 to 140 vessels crossing daily, but current data indicates a near-standstill amid the Iran war, sending oil prices higher and disrupting global energy markets[1][3]. The 30% crowd-implied probability for a return to normal by July 15 reflects the fragility of the recent uptick, where only 25 commercial vessels crossed on June 18, the highest since reopening, yet far below the 60-vessel threshold required for resolution[5][6].

Historical comparable cases suggest that without a stable US-Iran agreement enhancing security, traffic will not return to pre-war levels soon, as noted by an oil tanker CEO speaking to CNBC[1]. The catalysts traders must watch include any announced US-Iran diplomatic breakthroughs, as commercial shipping is expected to rise swiftly only if such a deal is established[1]. Additionally, monitor the expiry of war risk cover and the threat of missile attacks, which continue to deter some tanker owners despite recent rate hikes in container freight futures[2].

For traders comparing platforms, Polymarket offers decimal odds without KYC, whereas Kalshi and Betfair require identity verification and offer implied probabilities with different fee structures. On this specific market, the divergence in fee structures and KYC reach between these books may influence liquidity, as Polymarket’s lower barriers could attract more speculative volume compared to the regulated exchanges[1]. The market resolves when IMF PortWatch publishes a 7-day moving average of transit calls equal to or above 60, a condition unlikely given the strait’s current closed status[4][7].

Methodology

We read Strait of Hormuz traffic returns to normal by July 15? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
