Defense Stocks Fall as Democrats Sweep Congress: Northrop Drops 5%

Defense stocks fell sharply on Wednesday morning, November 4, 2026, even as the wider market rose. Northrop Grumman dropped about 5%, while RTX, Lockheed Martin and L3Harris each lost more than 3% in premarket and early trading after Democrats won control of both the Senate and the House of Representatives in the midterm elections. Investors are repricing one big assumption: that President Donald Trump's $1.5 trillion defense budget request would sail through a Republican-led Congress.

What happened to defense stocks?

The selloff hit the whole sector at once. According to Reuters, Northrop Grumman fell 5%, and RTX, Lockheed Martin and L3Harris lost over 3% each. Investopedia put Northrop and Lockheed down at least 3% in early trading and defense-data contractor Palantir Technologies off by about 5%. The drop was not only American: in London, Investors' Chronicle reported BAE Systems slumped 5% and Babcock fell more than 3%, as European defense shares caught the same downdraft.

Other politically exposed names fell with them. Reuters reported prison operators GEO Group down 6.7% and CoreCivic down 5.2%, Trump Media & Technology Group down about 7%, and Elon Musk's SpaceX and Tesla down 3.2% and 3.6% respectively in one premarket snapshot, with later reports showing larger falls. Data-center stocks such as IREN, Hut 8 and Applied Digital also slipped, on worries about tougher oversight of the AI buildout in states Democrats won, including Texas and Georgia.

Why are defense stocks falling?

The direct answer: a Democrat-led Congress may not approve defense spending at the level the sector had priced in. Reuters noted the sector had been underpinned by expectations that Trump's $1.5 trillion budget request would not face headwinds in a Republican-dominated Congress. With Democrats now controlling both chambers, analysts project the funding could fall short of expectations. Investors' Chronicle made the same point in plainer terms: Democratic control of Congress could hold up spending, and defense shares took a hammering as a result.

Nothing has actually been cut yet. No budget has been voted down, and no contract has been cancelled. Wednesday's move is about expectations — traders selling first and waiting to see what a divided Washington, with a Republican president and a Democratic Congress, actually negotiates over the coming months.

Why it's blowing up

The contrast is what makes this story travel. This was not a down day for stocks in general. Reuters, via Kitco, reported Dow futures up 1.44%, S&P 500 futures up 1.04% and Nasdaq-100 futures up 0.93% at 6:24 a.m. ET, as investors bet divided government could limit sharp policy shifts. Solar stocks were among the day's top gainers on the same news, with First Solar up 8.3% and Canadian Solar up 8.9%. So the election produced clear winners and losers within hours: clean energy up, defense, prisons and Musk-linked companies down, and the broad market relieved that the result was decisive.

The sweep itself was broader than expected. Democrats scored wins in Republican strongholds such as Kansas for the first time in generations, and President Trump accepted the results and acknowledged that the war in Iran played a role in Republicans' losses. Against that backdrop, the defense drop stands out as the sector most directly exposed to who controls Congress's purse strings.

What's next

Watch the budget process, not just the tickers. The key question is what defense appropriations a Democratic House and Senate will actually pass, and whether the $1.5 trillion request is trimmed, delayed or largely preserved in negotiation with the White House. Contractors with long backlogs do not lose existing work overnight, but new-program funding is where a changed Congress can bite first. Defense earnings calls and any early signals from congressional committees will show whether Wednesday's drop was a one-day repricing or the start of a longer reassessment.
