Strait of Hormuz traffic returns to normal by 2026?

Platform comparison

Market context

The key question is whether traffic through the Strait of Hormuz can get back to normalised levels quickly enough for a 7-day moving average of ship arrivals to hit 60 before 31 August. Recent reporting still shows volumes well below pre-crisis norms: Reuters said traffic was down to 33 vessels from Monday to Thursday in the week of 7 August, while other live trackers cited single-digit or low-teens daily counts and only a handful of crude tankers moving through[1][2][3].

History and comparable readings point to a market that is pricing a sharp recovery as unlikely, not impossible. Before the disruption, the strait typically handled roughly 70 to 140 vessels a day depending on the baseline used; during the crisis, IMF PortWatch-based summaries have shown averages around 4 to 18 a day, with one July report estimating about 9.9 transits per day since 1 March versus 103.2 in the same 2025 window[4][5]. That gap explains the low 4% yes price: on Polymarket the crowd probability is often quoted directly, while Kalshi and Betfair-style books are more likely to show decimal odds or exchange prices, and fees or withdrawal/KYC rules can make the same view look slightly different across platforms.

The main catalysts are any Iran-Oman or US-Iran announcement on routing arrangements, whether security incidents ease enough for carriers to resume AIS-tracked transits, and whether larger shipping lines restore regular schedules. Reuters reported on 7 August that markets were watching Iran-Oman talks as traffic dwindled, and other coverage on 8 August said Iran and Oman had agreed route coordinates in principle, but traffic was still highly disrupted and some vessels were reportedly turning off transponders[1][6]. For this market, the trigger is not rhetoric but a sustained IMF PortWatch 7-day average at or above 60, so even a short-lived uptick may not be enough unless it is broad-based and visible in the published data[4][6].

Methodology

This page compares Strait of Hormuz traffic returns to normal by 2026? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
