The probability of a Democratic victory in the Ohio Senate race rose 3 points to 73.5 percent on Polymarket in the latest 24-hour snapshot, according to PolymarketTrader.

The update was published on Oct 31, 2026, at 2:15 PM ET. The trading came three days before the November 3 midterm elections.

Price and trading activity

The contract was priced at 73.5 cents, placing a Democratic win above an even chance in the market’s pricing. The reported move reflects a higher implied probability, not a confirmed electoral outcome.

According to PolymarketTrader, the market recorded 136,000 dollars in trading over 24 hours and had 349,700 dollars in liquidity. The supplied summary did not identify a catalyst for the price increase.

What it means for prediction markets

  • The 3-point rise shows pricing shifted toward a Democratic victory during the latest 24-hour window.
  • The 73.5 percent implied probability still leaves uncertainty about the result; it is a market price rather than an election finding.
  • With three days remaining before November 3, the reported volume and liquidity provide context for activity but do not establish what drove the move.
