Senate swing-state contract leads prediction-market trading ahead of midterms

DeFi Rate ranked the Senate swing states market first among its top 50 prediction markets by 24-hour volume, with 128 outcomes and a Polymarket price of 25 cents for the leading outcome. Politics was the largest category on the board ahead of the November 3 midterms.

A market tracking which Senate swing states Republicans will win generated 1.9 million dollars in trading over 24 hours, placing it first in DeFi Rate’s ranking of the top 50 prediction markets by that measure.

The ranking, published Nov 1, 2026 at 8:45 AM ET, puts the Senate contest at the center of the trading activity described ahead of the November 3 midterms.

Volume leads, but the outcome picture is limited

According to DeFi Rate, the market included 128 outcomes. The leading outcome carried a Polymarket price of 25 cents, though the supplied summary does not identify that outcome.

Politics was the largest category on DeFi Rate’s board. That category-level position and the Senate market’s volume lead are distinct measures: neither, on its own, establishes which states traders expect Republicans to win.

What it means for prediction markets

  • The 1.9 million dollars figure measures trading over 24 hours. Its first-place standing applies to DeFi Rate’s top 50 ranking, rather than establishing a universal lead across all markets.
  • With 128 outcomes and only the leading outcome’s 25-cent price supplied, the information is insufficient to reconstruct state-by-state expectations.
  • The snapshot precedes the November 3 midterms; it describes activity at the reported time, not an election result.
