What the board measures

PredictionBubbles ranks moves by their absolute size in probability points, without adjusting placement for trading volume or liquidity. Its stated coverage spans 2,014 markets lasting longer than 14 days, excluding same-week fixtures to prevent short-lived settlement swings from dominating the board.

The $1.3M traded figure provides context for the Mahomes contract, but the supplied update does not specify its measurement period. Nor does the source excerpt include the individual contract card, its settlement terms or order-book depth, limiting what can be concluded about the trading behind the decline.

What it means for prediction markets

• Price and movement are separate signals: The 8% reading is the reported market-implied probability; the 3-point decline describes its change over 24 hours.
• Volume is not liquidity: The reported $1.3M traded does not establish how much trading would be needed to move the current price.
• The cause remains unspecified: The board documents repricing, but the supplied material does not explain why traders marked down Mahomes’ MVP prospects.
