Democratic control bets strengthen as equity futures retreat after midterms

According to CryptoBriefing, Nasdaq 100 futures dropped nearly 1.5 percent early on November 4, 2026, as midterm vote counts moved in Democrats’ favor. The S and P 500 also lost about 500 billion dollars in market value.

The report, published on Nov 4, 2026 at 8:00 AM ET, described an equity-market decline alongside increasingly strong prediction-market pricing for Democratic control of Congress.

Congressional odds favor Democrats

Prediction markets put the probability of a full Democratic sweep of Congress at about 95 percent, according to CryptoBriefing. The reported House probabilities ranged from 94 to 98 percent, while the odds of a Senate flip stood between 70 and 88 percent.

Those figures show stronger conviction around the House than the Senate. The summary does not identify the individual markets, their contract definitions or the precise timing of those probability readings, limiting direct comparisons with the reported sweep odds.

What it means for prediction markets

• The Senate remains the less certain chamber: Its reported 70 to 88 percent flip probability trails the House range of 94 to 98 percent.
• Contract details matter: The roughly 95 percent sweep probability exceeds the reported Senate range. Without market definitions and synchronized readings, the figures cannot be treated as a single, internally comparable forecast.
• Timing is not proof of causation: CryptoBriefing reported falling equities alongside counts favoring Democrats; the supplied summary does not establish that changing congressional odds caused the losses.
