Kansas Democrat surges 11 percentage points in Kalshi Senate market

The move from 40 percent to 51 percent is the largest seven-day gain on the midterm board as of October 31 at 8:55 AM ET. Minnesota Senate Democrats also rose 7 points to 91 percent and Michigan Democrat El-Sayed rose 7 points to 76 percent over the same window.

Kansas leads the seven-day move

The Kansas Senate Democrat reached 51 percent on Kalshi, up from 40 percent over the last seven days, according to DeFi Rate. The 11-point increase was the largest seven-day gain on the midterm board as of October 31 at 8:55 AM ET.

The move took the Kansas contract from below 50 percent to just above it. That makes its position distinct from the other Democratic gains highlighted in the report, which came from higher starting levels.

Minnesota and Michigan also rise

Minnesota Senate Democrats gained 7 points to reach 91 percent over the same window, according to DeFi Rate.

In Michigan, Democrat El-Sayed also rose 7 points, reaching 76 percent. Both increases were smaller than the Kansas move, although their reported probabilities remained substantially higher.

The figures were reported in an item published October 31, 2026, at 9:30 AM ET. The supplied summary does not identify a catalyst for the changes or provide trading-volume information.

What it means for prediction markets

  • Kansas crossed the midpoint: Its rise from 40 percent to 51 percent shifted the contract above 50 percent, but only narrowly.
  • Momentum and probability differ: Kansas recorded the largest seven-day gain on the midterm board, while Minnesota Senate Democrats and Michigan Democrat El-Sayed held higher reported probabilities.
  • The snapshot has limits: These figures describe pricing over a specific seven-day window. Without supporting information on catalysts or trading volume, they do not establish why the markets moved.
