Democratic Senate contracts advanced on both Polymarket and Kalshi on Friday, taking their implied probabilities above 70 percent, according to FinancialMarkets.

Polymarket’s price increased 4 cents to 72.5 cents, while Kalshi’s rose 4 cents to 71 cents. The figures appeared in a FinancialMarkets update published Nov 2, 2026, at 6:30 AM ET.

Prices and trading activity

The identical gains left Polymarket priced 1.5 cents above Kalshi. Both platforms moved in the same direction, although their Democratic Senate contracts remained at different levels.

According to FinancialMarkets, the largest single trade was a purchase of 50,000 contracts on Kalshi’s Democratic side at 71 cents. Polymarket had about $4.25 million in liquidity.

The summary provided no explanation for the price increases or additional detail about trading activity. It therefore does not establish what prompted Friday’s moves.

What it means for prediction markets

  • Direction aligned: Both platforms registered a 4-cent increase, placing Democratic Senate pricing above 70 percent on each.
  • A price gap remained: Polymarket stood at 72.5 cents versus Kalshi’s 71 cents; the supplied material does not explain the difference.
  • Trading context is limited: The 50,000-contract Kalshi purchase and roughly $4.25 million in Polymarket liquidity offer context, but neither establishes the cause of the gains or guarantees the outcome.
