Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

Traffic through the Strait of Hormuz is a real-world shipping test, not a legal abstraction: the contract turns on whether IMF Portwatch prints a 7-day moving average of **60 or more transit calls** for any date before 31 December 2026. On the latest crowd reading, **59% YES** is close to the threshold, which implies traders are still treating recovery as plausible but not settled. For accessibility, the market is the kind of product that can be offered with *no-KYC up to $1,500* on some platforms, meaning smaller balances may be traded with lighter identity checks, though larger activity usually triggers full verification; in the US, CFTC oversight can still matter because event contracts and platform access are shaped by US derivatives rules, while in Germany the GlüStV framework affects whether online prediction-market activity is treated as permitted gambling or requires licensing and age/identity controls.

Historical trading in this corridor suggests the key question is timing, not direction: Reuters reported in April that traffic was at less than 10% of typical volumes even after a ceasefire, with only seven vessels through in 24 hours versus a normal flow of around 140.[15] CNBC later said traders on Kalshi were assigning only a 43% chance that traffic would be back to normal by 1 December, while Polymarket was nearer 59% by 31 December, showing how sensitive pricing is to the pace of reopening rather than to any single headline.[2] That same split helps explain why a near-60% market can still be fragile if the shipping recovery remains uneven.

Catalysts are likely to be operational rather than rhetorical: traders should watch IMF Portwatch’s daily publication pattern, any ceasefire enforcement or sanctions-waiver implementation, and shipping-broker or insurer guidance that affects tanker routing and willingness to sail. A Congressional Research Service note on the June 2026 US-Iran MOU said the arrangement included waivers for Iranian oil exports and related services, including banking, insurance and transportation, which is the sort of dependency that can move vessel counts quickly if implemented cleanly.[13] Reuters and CNBC coverage also show that even when diplomacy improves, actual transit recovery can lag by weeks, so the next qualifying Portwatch print matters more than broad sentiment.[15][17]
