US-Yemen ceasefire contract surges 50 points to above 99% on Polymarket

Ceasefire contract approaches 100%

A Polymarket contract on a US-Yemen ceasefire holding through Oct. 15 climbed from 50% to above 99%, according to DeFi Rate’s biggest-movers summary.

The panel covered the seven days ending Oct. 13 at 7:45 PM ET. The headline described the increase as a 50-point surge, putting the contract close to the top of its probability range.

The move represents a sharp repricing of the contract’s outcome, not confirmation that its ceasefire condition has been met. The material provided does not identify what prompted traders to revise their expectations.

There are also limits to the available reporting: the supplied defirate.com excerpt concerns Florida International vs Jacksonville St., rather than the ceasefire market. It provides no supporting detail on the Polymarket contract’s trading volume, liquidity or resolution criteria.

What it means for prediction markets

• Timing matters: The reported odds are a snapshot as of Oct. 13 at 7:45 PM ET, ahead of the contract’s Oct. 15 horizon.
• Price is not resolution: A reading above 99% signals a heavily favored outcome in market pricing, but does not establish that the contract has settled.
• Market context is missing: Without volume, liquidity or contract rules, the supplied material cannot establish how broad the repricing was or precisely what would determine the result.
