Polymarket bettors have estimated a 17 percent likelihood that the Bab el-Mandeb Strait will effectively close to traffic by the end of 2026. This assessment relies on IMF PortWatch data tracking whether the seven-day moving average of ship arrivals falls to 10 or fewer.
Why it matters
The prediction contract serves as a barometer for market sentiment regarding potential global shipping disruptions that could impact energy prices and inflation. The resolution of this market highlights the ongoing risks to maritime trade routes and the subsequent reliance on alternative paths like the Cape of Good Hope.
The prediction market recorded $16,845,201 in total volume alongside $506,999 in liquidity. Prices have climbed from 6.5 percent for an October 31 resolution to 16.5 percent for the December 31 deadline as of October 12, 2026.
