Brock Purdy’s MVP contract on Kalshi was priced at 15.0%, down 9.0 probability points, with $1.7M traded, in the supplied update published Oct 25, 2026 · 7:24 PM ET. According to PredictionBubbles, the contract appeared among the downward moves in its sports category, rather than as the board’s lead item.
The decline reflects a lower market-implied probability over the preceding 24 hours. The supplied material does not identify a Purdy-specific development behind the repricing or establish the period covered by the $1.7M trading figure.
How the move is measured
According to PredictionBubbles, its movers board compares prices from Polymarket and Kalshi over 24 hours and updates every 15 minutes. The supplied snapshot records venue data read on 25 Oct 2026, 23:18 UTC.
The board ranks changes by their absolute size in probability points, not by relative percentage returns. Volume and liquidity provide context but do not affect a contract’s position in those rankings. Purdy’s 9.0-point decline therefore describes a shift in the market’s assessment, not a 9.0% relative fall.
Scope and limits
PredictionBubbles says the snapshot covers 1,977 markets with lifespans longer than 14 days. It excludes same-week fixtures and requires open markets to have a valid 24-hour price comparison. Its main table displays the top 150 of 518 markets that moved at least one probability point.
Those filters make the board a measure of repricing within a defined market universe, rather than a comprehensive account of sports trading. The supplied excerpt does not include Purdy’s order-book depth, contract resolution terms or a verified explanation for the decline.
What it means for prediction markets
Price signal: The 15.0% reading captures the contract’s market-implied probability at the reported snapshot, not a confirmed assessment of the eventual MVP outcome.
Activity versus liquidity: The reported $1.7M traded adds context, but without a specified volume window or order-book depth, it cannot establish how readily traders could transact at that price.
Causation remains unverified: The 9.0-point drop establishes that pricing changed. The supplied reporting does not show why.
