Prediction markets currently give a 20% probability that Will the Democratic Party hold 51 seats in the 120th Congress?. This contract trades at 20¢ on Kalshi, closing February 1, 2027. The market is pricing Democrats at just 21% to hold exactly 51 Senate seats by February 2027, reflecting expectations of either Republican gains or a split outcome, though the extremely high Yes-side implied yield of 502% suggests substantial underpricing risk if Democrats perform better than consensus.

Analysis

4d ago

The market is pricing Democrats at just 21% to hold exactly 51 Senate seats by February 2027, reflecting expectations of either Republican gains or a split outcome, though the extremely high Yes-side implied yield of 502% suggests substantial underpricing risk if Democrats perform better than consensus. With $47k open interest and only a 1¢ spread, liquidity is moderate but the neutral regime score (0.396) indicates uncertainty about directional momentum over the 291-day window. The flat 7-day price action (holding at 20¢) combined with moderate 24h volume of $10k suggests this market lacks conviction, making it potentially vulnerable to sharp repricing if polling or political developments shift.

Resolution rules

If the Democratic Party has exactly 51 Senate seats on Feb 1, 2027, then the market resolves to Yes.
