Polymarket participants have priced the probability of the Bab el-Mandeb Strait effectively closing to shipping at 17 percent by year-end. This outcome hinges on IMF PortWatch data reporting a seven-day moving average of 10 or fewer vessel arrivals.
Why it matters
The contract reflects shifting risk sentiment regarding global supply chain reliability and the potential for diverted traffic around the Cape of Good Hope to inflate energy costs and overheads. Companies monitoring maritime logistics now have a live financial indicator for regional volatility.
The prediction market has generated $16,845,201 in total volume with $506,999 in liquidity to hedge or speculate on maritime transit risks. The resolution threshold is set at a seven-day moving average of 10 or fewer ship arrivals via IMF PortWatch.
The players
Polymarket
A decentralized prediction market platform that allows users to bet on the outcome of real-world events.
IMF PortWatch
A data platform operated by the International Monetary Fund that monitors real-time maritime trade activity.
The details
The contract resolves based on objective ship arrival data provided by the IMF PortWatch tracker. If maritime activity in the Bab el-Mandeb Strait falls to or below 10 ships on a seven-day moving average, the contract pays out to Yes participants. Traders use this market to calibrate risk appetite for goods moving between Asia and Europe, which are subject to higher fuel and time costs when forced to reroute.

Market Landscape
This market pricing follows the ongoing trend of shipping diversions around the Cape of Good Hope driven by regional maritime instability. It quantifies the market's current expectation for a sustained disruption that exceeds earlier levels of volatility seen in 2026.
Operators should review freight contracts and insurance clauses to ensure coverage for extended transit times or force majeure declarations in the event of a strait closure. Consider diversifying supplier lead times to account for the potential of further maritime disruptions through the end of 2026.
The takeaway
The pricing of this contract signals that the market views Red Sea transit risk as a persistent variable rather than a short-term anomaly. Monitor IMF PortWatch data to track whether maritime arrivals are trending toward the 10-ship threshold as the year-end deadline approaches.
