Senate swing-state contract leads DeFi Rate ranking as None price rises
DeFi Rate ranked the Polymarket market first among its top 50 on October 31, with the None outcome priced at 23 cents, up 22 points in seven days. Politics accounted for 19 million dollars of the board's 24 hour volume across 20 markets.
According to DeFi Rate, Polymarket’s market on which Senate swing states Republicans will win generated $3.7 million in trading volume over 24 hours, placing it first among the outlet’s top 50 markets on October 31.
The ranking was published on Oct 31, 2026, at 6:00 PM ET. It highlights trading activity around Republican Senate outcomes, alongside a weekly price increase for the market’s None outcome.
None outcome gains ground
The None outcome was priced at 23 cents, up 22 points in seven days, according to DeFi Rate. That price movement is distinct from the $3.7 million volume figure, which covers the market as a whole over 24 hours.
The supplied summary does not identify the individual swing states or give prices for the other outcomes. It therefore offers no state-by-state picture of how traders priced Republican wins.
Politics draws broader activity
Politics markets accounted for $19 million in 24-hour volume across 20 markets on DeFi Rate’s board. The Senate swing-state contract’s leading position sat within that wider pool of political trading.
The summary does not provide the board’s total volume across all categories. Politics’ share of overall activity therefore cannot be calculated from the supplied figures.
What it means for prediction markets
- Activity and pricing are separate signals: The $3.7 million figure establishes the contract’s volume lead in DeFi Rate’s ranking, not the likelihood of any particular result.
- The weekly move is outcome-specific: None rose 22 points to 23 cents, but the supplied figures do not show how other outcomes moved.
- The ranking has a defined scope: First place applies to DeFi Rate’s top 50 on October 31, rather than establishing a lead across every prediction market.
