Polymarket’s contract on whether the Israel–Iran ceasefire continues through December 31 was priced at 33.0%, down 6.5 probability points over 24 hours, with $1.2M traded. According to PredictionBubbles, the December-dated contract appeared among declining markets in its political/election category.
The figures accompanied an update published Oct 25, 2026, at 4:39 PM ET. PredictionBubbles lists its underlying venue-price snapshot as 25 Oct 2026, 20:16 UTC, and says it updates the board every 15 minutes.
The decline indicates a lower market-implied probability of ceasefire continuation through the contract’s December 31 deadline. The supplied material does not identify a diplomatic or military development behind the move, so it does not establish why traders changed their pricing.
The $1.2M traded provides activity context, but the supplied headline does not specify its measurement period. It also does not provide order-book depth or the contract’s detailed resolution criteria—limits that matter when interpreting both the price change and precisely what outcome traders are assessing.
According to PredictionBubbles, the board compares Polymarket and Kalshi contracts by the size of their 24-hour probability-point changes, rather than relative percentage changes. Trading volume and liquidity provide context but do not determine the rankings.
The snapshot covers 1,988 markets with lifespans longer than 14 days. Only open contracts with a valid 24-hour comparison qualify; resolved markets and those too new to have a comparable earlier price are excluded. The ceasefire contract’s appearance therefore signals a measured repricing, not an independently verified change in the ceasefire’s status.
A Kalshi contract described as “Houston wins” was priced at 48.0%, down 33.0 percentage points, with $6.1M traded, according to the supplied market headline published Oct 25, 2026 · 4:39 PM ET. The figures show a substantial repricing, but the accompanying material does not identify the contest or its settlement conditions.
The supplied news-search summary reported no significant new platform headline in the last 30 minutes. It did not establish a fresh catalyst for Houston’s decline. That leaves the price movement observable but its cause unconfirmed.
According to predictionbubbles.net, its movers page compares market-implied probabilities over 24 hours using prices obtained from Polymarket and Kalshi. The supplied page records a venue-data snapshot of 25 Oct 2026, 20:16 UTC and says it refreshes every 15 minutes. However, the excerpt does not contain a Houston-specific entry independently confirming the headline figures.
PredictionBubbles ranks changes by their magnitude in probability points, rather than relative percentage changes. On that basis, Houston’s reported decline is 33.0 percentage points—not a 33.0% relative fall.
The $6.1M traded figure provides activity context, but the headline does not specify its measurement period. Nor does the supplied material establish available liquidity or explain which information traders were responding to. PredictionBubbles distinguishes trading volume from price movement and does not use volume to determine its mover rankings.
