The Polymarket contract on the Milwaukee Brewers winning the 2026 World Series was listed at 100.0%, up 8.0 probability points, with $3.2M traded in the supplied market headline published Oct 29, 2026, at 12:54 AM ET. Those figures describe the contract’s pricing, not independent confirmation of the championship result.
According to predictionbubbles.net, its movers dashboard measures changes over 24 hours using prices collected from Polymarket and Kalshi. The supplied page records a venue-data snapshot of 29 Oct 2026, 04:47 UTC, with updates every 15 minutes.
The dashboard ranks contracts by the magnitude of their probability-point changes, rather than their relative percentage gains or trading volume. On that basis, the Brewers’ reported 8.0-point increase represents a change in the market-implied probability, not an 8.0% relative return.
The supplied predictionbubbles.net excerpt explains the dashboard’s methodology but does not contain a Brewers-specific listing. The 100.0% price, 8.0-point move and $3.2M traded therefore come from the supplied headline; the excerpt does not independently corroborate them or specify the period covered by that trading figure.
Predictionbubbles.net says its rankings include only open contracts with a valid 24-hour comparison and exclude resolved markets. Neither the excerpt nor the accompanying summary provides a game result, an official settlement notice or a specific catalyst for the Brewers repricing.
Anthropic’s Polymarket contract on whether it will have the highest IPO market capitalization in 2026 stood at 48.6%, up 10.2 percentage points over 24 hours, with $1.4M traded, according to the supplied PredictionBubbles snapshot published Oct 29, 2026, at 12:54 AM ET.
The move lifted the contract’s implied probability substantially, while leaving it below 50%. The supplied material does not identify a news event behind the change or provide the contract’s detailed resolution criteria.
PredictionBubbles distinguishes price movement from trading activity: its movers ranking uses absolute probability changes over the preceding 24 hours, while its volume ranking uses total traded volume. The $1.4M figure therefore should not be read as turnover generated during Anthropic’s latest price rise.
The summary’s Oct. 29, 04:40 UTC crawl recorded 188 open markets and $163.4M traded across the finance board. The supplied page text separately lists 189 markets, comprising 15 from Kalshi and 174 from Polymarket. Those counts reflect different supplied snapshots rather than a single consistent board reading.
According to PredictionBubbles, its finance data refreshes every 15 minutes, although trading on the underlying venues continues between updates. The page identifies the Polymarket contract asking whether there will be no Fed rate cuts in 2026 as the board’s most-traded finance market at its last refresh, with $9.2M traded.
