Democrats Sweep House and Senate in Historic Midterm Rebuke of Trump, Jolting Markets and AI Trade

Democrats seized control of both chambers of Congress in a sweeping midterm election on November 3-4, 2026, delivering one of the most decisive repudiations of a sitting president's party in decades. The party flipped six Senate seats and won the House with what NBC projected could be its largest majority in nearly two decades, giving Democrats 54 Senate seats and roughly 225 or more House seats once counting advanced. Voters cited the cost of living and the ongoing war with Iran as primary drivers of their discontent with Republican governance.

The results produced a cascade of historic firsts. Democrat James Talarico defeated Republican Attorney General Ken Paxton to win a Texas Senate seat, the first Democratic Senate victory in the state since 1988. Democrat Gina Hinojosa ousted three-term Republican Governor Greg Abbott, flipping the Texas governorship for the first time since 1990 and making her the first Latina governor of the state. In Kansas, Democrat Adam Hamilton defeated Trump-backed Senator Roger Marshall, becoming the first Democrat elected to the Senate from that state since 1932. Sherrod Brown returned to the Senate by defeating Republican Jon Husted in Ohio, two years after losing his seat. Democrat Annie Andrews flipped the South Carolina Senate seat, defeating Darline Graham in a state Trump had carried by 18 points in 2024. Democrat Troy Jackson defeated five-term Republican Susan Collins in Maine, ending her roughly 30-year career. In Michigan, progressive Democrat Abdul El-Sayed defeated former Republican Representative Mike Rogers to become the first Muslim elected to the United States Senate. Democrats also flipped Senate seats in Iowa, North Carolina, and Iowa, while Amy Acton won the Ohio governorship by defeating Vivek Ramaswamy and Amy Klobuchar won the Minnesota governorship.

President Trump told the New York Times he was "absolutely willing to accept those results" and said "we'll work with the Democrats... we'll probably work something out." He blamed Republican losses on his absence from the ballot, posting on Truth Social that the GOP "would have won IN A LANDSLIDE" had his name appeared. In separate interviews with the Wall Street Journal and Fox News, Trump acknowledged the Iran war was "a piece of it," saying rising oil and gasoline prices were the biggest political liability, while insisting he had no regrets about launching the conflict. The White House atmosphere was described by officials as "dark" and "funereal."

Markets reacted sharply. The US Dollar Index fell below 101.50 to its lowest level in roughly five weeks, with the dollar dropping 0.56% against the yen to 157.77 and 0.86% against the Swiss franc to 0.8138. Gold reclaimed $4,000 per troy ounce as the dollar weakened and Treasury yields declined in a bull-steepening move, with two-year and five-year yields falling roughly 7 basis points. Bitcoin slid to a seven-week low of approximately $75,700 before staging a V-shaped recovery to above $78,000. US stock futures initially sold off sharply, with Nasdaq 100 futures falling as much as 2.4%, before recovering to show Dow Jones futures up roughly 800 points and S&P 500 futures up about 1.1% ahead of Wednesday's open. Japan's Nikkei fell 2.9% and South Korea's KOSPI swung through a seven-percentage-point range before closing higher.

The Texas results drew particular attention from investors because Governor-elect Hinojosa had called for a moratorium on new data center development, stricter power and water regulations, and an end to data center tax breaks. Jefferies estimated her victory puts 13.1 gigawatts of announced Texas data center projects at immediate risk. Tesla and SpaceX shares fell approximately 4% and 7% respectively in premarket trading, while CoreWeave slipped 3.6% and AI infrastructure stocks broadly faced selling pressure. Renewable energy stocks and gold-related shares surged. Goldman Sachs noted that Democrats' larger-than-expected majorities would dilute the influence of small factions within the party, and expected Democrats to use fiscal deadlines to seek limits on the Iran war, roll back selected tariffs, and reverse some spending cuts. Bank of America characterized gridlock as the base case, noting that Trump retains veto power and that overriding it requires a two-thirds majority Democrats do not possess.

Iran's government publicly savored the outcome. Parliament Speaker Mohammad Baqer Qalibaf wrote that "Americans said NO TO WAR," and Iran's Foreign Ministry said Trump had been sent "a clear message." Trump said the United States had no immediate plans for further Iran strikes and that talks through mediators were ongoing. Democrats meanwhile signaled plans to investigate the Trump family's crypto ventures, which Reuters reported had generated at least $2.3 billion since Trump returned to office.

Separately on Wednesday, ADP reported that US private employers added 86,000 jobs in October, above the 67,000 consensus estimate. The Treasury's quarterly refunding announcement came in at $125 billion, in line with expectations, comprising $58 billion in three-year notes, $42 billion in ten-year notes, and $25 billion in thirty-year bonds.
