Political contracts dominate trading as Senate swing states lead turnover

Sports accounted for 15 of the top 50 markets and 8 million dollars of the 24-hour volume in the late October 31 board. The Senate swing states market was the most traded market overall at 3.6 million dollars in 24 hours.

Politics represented 30 of the top 50 prediction markets on the late October 31 board, accounting for 19 million dollars of the 28 million dollars traded over 24 hours, according to DeFi Rate.

Politics leads the board

The figures put politics ahead of sports in both the number of markets represented and trading volume. Political contracts accounted for more than half of the top 50 markets and more than half of their 24-hour turnover.

The Senate swing states market led all individual markets, with 3.6 million dollars traded in 24 hours, according to DeFi Rate. That placed a Senate-focused contract at the center of the board’s trading activity.

Sports holds a substantial share

Sports accounted for 15 of the top 50 markets and 8 million dollars in 24-hour volume. Its market count was half that of politics, while its turnover was less than half the political total.

The snapshot was published on Oct 31, 2026, at 11:45 PM ET. It describes activity on the late October 31 board, rather than a longer-term pattern in trading.

What it means for prediction markets

  • Politics was the principal concentration of trading activity in this top-50 snapshot, leading sports by both market count and volume.
  • The Senate swing states market’s 3.6 million dollars in turnover made it the most actively traded individual market, but volume alone does not indicate which outcome traders favored.
  • The supplied figures do not include prices or probability changes, limiting conclusions about whether the activity reflected a shift in expectations.
