what happened
Traders on prediction platforms are increasingly betting that Democrats will win both the House and Senate in Tuesday's midterm elections, Seeking Alpha reported. Kalshi's balance-of-power market put the probability at about 70% on Sunday morning, while Polymarket showed 72%. Both figures are far above the levels seen earlier in the autumn, when a Democratic sweep was below 50% in early September.
Within individual chambers, Kalshi puts Democratic control of the Senate near 72% and of the House around 94%. Currently Republicans hold both chambers, with a 53-47 Senate majority and a slim House margin.
why it matters
Prediction-market prices can move quickly as polls, campaign news and new information arrive before Election Day. Investors often watch these odds for signals on future regulation, taxes and government spending, since a change in congressional control could reshape policy expectations.
