Prediction Markets Put Democrats at 99% for Senate, 100% for House Control

Prediction markets put Democrats at a 99% chance of controlling the Senate and 100% for the House, signaling a likely shift in congressional power if the outlook holds.

The same odds appeared across both markets, where participants favored a Democratic sweep of the two chambers. The House estimate was one percentage point above the Senate reading. Both figures point to the same outcome: Democrats controlling both parts of Congress rather than a split between parties.

The Senate probability remained just below certainty, while the House reached the maximum displayed probability. The percentages describe bettors' expectations for control of each chamber, not the share of votes cast. A sweep means one party holds control of both the Senate and the House.

The market outlook centers on unified Democratic control of Congress, with the House at 100% and the Senate at 99%. Those probabilities are not a final vote tally and do not by themselves establish that control has changed.
