Where the Buffalo move fits

PredictionBubbles tracks price changes across Kalshi and Polymarket. Its ranking covered 1,997 markets with lifespans longer than 14 days, excluding same-week fixtures to keep rapid settlement-related swings from dominating the results.

Buffalo appeared in the sports category rather than as the overall lead mover. The supplied material does not give its precise rank or identify a news development behind the increase.

Price movement versus trading activity

According to PredictionBubbles, the ranking depends on the size of the 24-hour probability-point change—not trading volume or liquidity. Only open contracts with a valid day-earlier comparison qualify, and a change of at least one probability point counts as movement.

The $787K traded provides context for Buffalo’s repricing, but the supplied headline does not specify that figure’s measurement period. It also does not provide order-book depth, so the volume alone cannot establish how much liquidity supported the move.

What it means for prediction markets

• The change is 2 probability points, not 2%. The 20% price reflects a higher market-implied estimate than a day earlier.
• The ranking measures repricing, not conviction. Buffalo’s appearance among upward movers does not establish why traders changed their assessment or whether the move will persist.
• Volume and liquidity remain separate questions. The reported $787K is useful context, but the supplied material does not establish market depth or the catalyst for the increase.
