A prediction market platform reported that contracts tied to Democratic control of the U.S. House currently trade above 50 percent. The assessment places the probability of a Democratic majority after the November midterms at the highest level recorded on the platform this cycle.

The same contracts show Republican control priced below even odds. Traders have adjusted positions steadily since the start of the year, according to the platform's public data feed.

Daily volume on the House-control contracts has risen each week for the past month. Open interest now exceeds previous peaks set during the 2024 cycle. Platform operators said the shift reflects updated polling averages and fundraising reports released in recent weeks. No single event was cited as the primary driver.

Voters will decide all 435 House seats on November 3.

The chamber's majority determines committee leadership and the legislative agenda for the following two years.
