Who Controls Congress in 2026?

US election Polymarket odds show a clear lean ahead of the November 3, 2026 midterms: traders see Democrats as favorites to win both the House and the Senate. On Polymarket’s balance of power market, a Democratic sweep trades at 63% and a Democratic House with a Republican Senate at 29%; together imply roughly a 91% chance that Democrats control the House. A Republican sweep sits at 9%.

All 435 House seats are on the ballot, 218 are needed for a majority, and Republicans currently hold the chamber, so a Democratic win would flip it. For the crypto market, that possibility could shape market structure legislation and oversight, but a market price does not predict that any particular bill will pass.

What Do the Latest US Election Polymarket Odds Show for the House and Senate?

The House figure is a sum rather than a single contract. The 63% Democratic sweep plus the 29% Democratic House outcome gives about 91% for a Democratic majority, while the 9% Republican sweep and the 1% Democratic Senate, Republican House outcome leave Republicans near 10%.

The Senate is closer, and its direction has changed sharply. Democrats trade at 65% to win the chamber and Republicans at 38%, after Republicans were priced near 70% in autumn 2025 and the two parties crossed in March.

The balance of power market has drawn about $24 million in volume and the Senate market about $6.7 million, so both carry real money behind them.

House Control Could Change the CLARITY Act’s Path

The CLARITY Act, digital-asset market structure and oversight priorities are areas that could be affected by a change in House control. It did not establish a policy program for a Democratic majority or claim that the bill would become law.

Congress.gov records the Digital Asset Market Clarity Act of 2025, H.R. 3633, as having passed the House on July 17, 2025, by 294 votes to 134. Its bill page lists the latest action as a September 15, 2026, motion to reconsider the vote by which cloture on a motion to proceed was not invoked; the bill has not completed the steps to become law.

The bill concerns digital-asset market structure and oversight. Its prospects would still depend on action beyond House control.

If Democrats win the House, committee leadership and oversight priorities could shift, potentially changing how lawmakers approach digital-asset market structure and the allocation of SEC and CFTC responsibilities.

That influence would be over the debate and its scrutiny, not unilateral power, because the outcome still depends on Senate action and the president’s signature.

A 10% Republican chance is not zero, so these US election Polymarket odds are best read as a snapshot of House control with policy implications, not as the odds that CLARITY passes.
