About this market
This market will resolve to “Yes” if IMF PortWatch publishes a 7-day moving average of transit calls (“Arrivals of Ships”) for the Bab el-Mandeb Strait less than or equal to 10 for any date between market creation and the listed date. Otherwise, this market will resolve to “No”. This market will resolve as soon as IMF PortWatch publishes a 7-day moving average of transit calls for the Bab el-Mandeb Strait equal to or below 10, or once data has been published for the listed date and no such value has been published. If no data has been published for the listed date within 14 calendar days (ET) after that date, this market will resolve based on the data published up to that point. Revisions to previously published data points made before data has been published for the listed date will be considered; however, they will not disqualify a previously published data point from qualifying. Revisions made after data has been published for the listed date will not be considered. The resolution source for this market will be IMF PortWatch, specifically the “Arrivals of Ships” data published for the Bab el-Mandeb Strait at https://portwatch.imf.org/pages/6b1814d64903461b98144a6cc25eb79c.
Frequently asked questions
What is this prediction market about?
This is a Polymarket prediction market asking: "Bab el-Mandeb Strait effectively closed by September 30?". Traders buy "Yes" tokens if they think the event will occur, or "No" tokens if they think it will not. Each token's price (in cents on the dollar) represents the market's consensus probability of that outcome.
What is the current probability?

When does this market resolve?
This market is scheduled to resolve on Apr 30, 2026. After resolution, the winning side's tokens redeem at $1 each (in USDC) and the losing side at $0.
How is the outcome decided?
Resolution follows Polymarket's standard process via UMA's optimistic oracle: a proposed outcome is submitted, and anyone may dispute it within a challenge window before settlement.
What does buying YES or NO actually mean?
"Yes" and "No" are outcome tokens on the Polygon blockchain. Each one pays out $1 in USDC if its outcome resolves true, otherwise $0. If you buy "Yes" at 9.5¢ and the outcome resolves "Yes", you receive $1 per token; if it resolves "No", your "Yes" tokens are worth nothing.
