Infiniti Briefing

Polymarket’s contract on whether the US–Iran ceasefire continues through October 28 was priced at 89.5%, up 3.0 probability points, with $885K traded, in the Oct 25, 2026 · 8:09 AM ET update. According to PredictionBubbles, the contract appeared among the political moves on its movers board.

Reading the repricing

The increase represents a higher market-implied probability of ceasefire continuation, not confirmation of the outcome. The supplied material identifies no diplomatic development or other news event explaining the change.

According to PredictionBubbles, its board measures changes over 24 hours and updates every 15 minutes using prices from Polymarket and Kalshi. The supplied snapshot records venue data retrieved on 25 Oct 2026, 11:40 UTC.

What the board measures

PredictionBubbles orders markets by the absolute size of their probability-point changes, rather than relative percentage gains or trading volume. The 3.0-point rise therefore measures a shift in the contract’s implied probability; it is not a 3.0% relative increase.

The $885K traded provides a separate activity measure, but the supplied material does not establish the contract’s order-book depth or explain who drove the move. PredictionBubbles treats volume and liquidity as context, without using either to determine the movement ranking.

What it means for prediction markets

• A high price is not a settled result: The 89.5% reading reflects market pricing for continuation through October 28, not verification that the ceasefire will last.
• The catalyst remains unspecified: The available reporting supports a repricing story, but not an explanation tied to a particular geopolitical event.
• Movement and activity are distinct: The 3.0-point increase and $885K traded describe different aspects of the market; neither alone establishes liquidity or the reliability of the implied probability.
