Seven-state Senate contract leads Polymarket activity as implied odds rise

ProbCast's 24-hour volume board ranks the Polymarket market on Republicans losing the Alaska, Iowa, Kansas, Maine, Michigan, Ohio and Texas Senate seats first among real-money markets, with 1.9 million dollars traded at 26 percent, up 3 points. ProbCast grades the move as developing rather than confirmed.

A Polymarket contract on Republicans losing Senate seats in Alaska, Iowa, Kansas, Maine, Michigan, Ohio and Texas recorded 1.9 million dollars in trading over 24 hours, according to ProbCast. It traded at 26 percent, up 3 points.

Volume leads, but signal remains developing

ProbCast’s 24-hour volume board placed the contract first among real-money markets. The ranking and pricing were reported on Nov 1, 2026 · 8:30 PM ET.

The contract concerns Republicans losing all seven named seats. Its 26 percent price therefore represents the market’s assessment of that combined outcome, rather than the odds for any individual Senate race.

ProbCast classified the move as developing, not confirmed. That distinction separates the reported increase in price and trading activity from a stronger judgment about the signal.

What it means for prediction markets

  • Combined outcome: The contract’s pricing should not be read as a separate probability for Alaska, Iowa, Kansas, Maine, Michigan, Ohio or Texas.
  • Activity versus conviction: The 1.9 million dollars in 24-hour volume establishes its position atop ProbCast’s real-money volume board, not confirmation of the outcome.
  • Signal status: The 3-point rise to 26 percent remains a developing move under ProbCast’s assessment.
