Puma Shen’s contract to win the next Taipei Mayor election was priced at 30.9% on Polymarket, down 6.9 percentage points over 24 hours, with $910K traded. According to PredictionBubbles’ movers board, the contract was among the declining markets in its political/election category.
A decline in the market’s assessment
The figures accompanied an update published Oct 25, 2026, at 2:39 PM ET. PredictionBubbles listed its underlying venue-price snapshot as 25 Oct 2026, 18:14 UTC, and said it refreshes the board every 15 minutes.
The supplied material does not identify a campaign development, poll or other event behind Shen’s decline. It establishes a change in the contract’s market-implied probability, but does not explain why traders repriced the outcome.
How the board measures movement
According to PredictionBubbles, its rankings compare absolute probability-point changes over 24 hours across Polymarket and Kalshi. Trading volume and liquidity provide context but do not determine a market’s position, so the $910K traded figure is separate from the 6.9-point decline.
The board’s stated universe covered 1,983 markets lasting longer than 14 days. It excludes resolved contracts and those without a valid 24-hour comparison; its main table displayed the top 150 of 506 markets moving at least one probability point. Shen’s placement among downward political moves does not establish that it was the board’s largest decline.
What it means for prediction markets
- Measure the move in points: The decline was 6.9 percentage points, not a 6.9% relative decrease.
- Separate price from explanation: The 30.9% reading reflects the contract’s market pricing at the reported snapshot, not independent evidence of a change in electoral conditions.
- Keep volume in context: The $910K traded figure does not, by itself, establish order-book depth or identify what drove the repricing.
- Treat the reading as time-specific: The board refreshes every 15 minutes, so the reported probability is not necessarily the current price.
