Darian Mensah win the Heisman Trophy priced at 22.0% on Kalshi, down 3.0 points, on $2.1M traded

Darian Mensah’s market-implied probability of winning the Heisman Trophy stood at 22.0% on Kalshi, down 3.0 percentage points, with $2.1M traded, according to PredictionBubbles’ movers listing.

The listing places the Mensah contract among declining sports markets, rather than as the board’s overall lead. The supplied material does not identify a sporting development or other catalyst behind the decline.

How the move is measured

According to PredictionBubbles, its movers board compares probabilities over 24 hours, using prices from Polymarket and Kalshi and refreshing every 15 minutes. The supplied page records a venue-data snapshot of 25 Oct 2026, 15:12 UTC.

The board ranks moves by their size in probability points, not by relative percentage change. Mensah’s 3.0-point decline therefore describes a shift in the market’s implied probability, not a 3.0% relative reduction.

What the board does—and does not—show

PredictionBubbles says its ranking covers 2,006 markets with lifespans longer than 14 days, excluding same-week fixtures. Only open markets with a valid 24-hour comparison qualify; the displayed table contains the top 150 of 507 markets moving at least one probability point.

Trading volume provides context but does not affect the ranking. The $2.1M figure attached to Mensah’s contract should not, on its own, be treated as evidence of order-book depth or an explanation for the price change. The supplied headline does not specify the period covered by that volume.

What it means for prediction markets

• Direction is clear; cause is not: The listing records a lower market-implied probability for Mensah, without supplying a catalyst.
• Keep the units straight: The reported decline is 3.0 percentage points, leaving the contract at 22.0%.
• Separate activity from liquidity: $2.1M traded adds context, but the supplied material does not establish how readily traders could transact at the displayed price.
• Treat it as a snapshot: The board updates every 15 minutes, so the reported probability is not a fixed assessment of the eventual result.
