Which Senate Swing States will Republicans win: "None" priced at 23% on Polymarket, on $2.6M traded in 24 hours

The “None” outcome in Polymarket’s Senate swing-states market was priced at 23%, with $2.6M traded over 24 hours, according to DeFi Rate’s odds hub. That outcome represents Republicans winning none of the Senate swing states covered by the market.

DeFi Rate ranked the market second among its most-traded markets. The reported volume applies to the market overall, not specifically to trading in “None.”

A snapshot with limited detail

The supplied summary places the price observations between Oct. 31, 4:26 AM and 4:56 AM ET. The headline was published on Oct 31, 2026 at 4:54 AM ET, so the observation window extends beyond that publication timestamp.

The available material does not identify the states included, provide prices for competing outcomes or describe the market’s resolution criteria. It therefore supports a snapshot of pricing and activity, rather than a state-by-state assessment or a conclusion about how expectations have changed.

What it means for prediction markets

• The 23% price is outcome-specific: It concerns Republicans winning none of the covered swing states, not overall Senate control.
• Volume is not directional evidence: The $2.6M traded in 24 hours does not establish whether traders were moving toward or away from “None.”
• Timing and scope matter: The figures reflect the stated observation window; the supplied material does not establish subsequent prices or the precise set of races covered.
