US defense stocks slide as investors bet on a Democratic midterm sweep
Shares of weapons makers fell further as traders priced in a Democratic win in November, putting a proposed $500bn boost to military spending in doubt, the FT reported.
The short answer
US defense stocks tumbled as investors bet Democrats will sweep November's midterm elections, the Financial Times (FT) reported, putting President Donald Trump's proposed $500 billion military spending increase at risk. The sector was already down nearly 19% from its August peak by mid-October after two years of big gains, and analysts are divided on what comes next.
What happened
According to the Financial Times (FT), US defense shares fell sharply as investors positioned for a Democratic sweep in November's midterm elections. The FT said Trump's proposed $500 billion boost to military spending is at risk as bipartisan support for a bigger budget weakens. The slide builds on an earlier rout: the 29-member S&P 1500 Aerospace and Defense Index had dropped nearly 19% from its early-August high by October 14, Bloomberg reported. Lockheed Martin and Northrop Grumman were each down by double digits over that stretch, and GE Aerospace lost 19% as higher fuel prices clouded the outlook for air travel.
What it means
Defense companies depend heavily on government budgets, so their shares are sensitive to who controls Congress. Investors who expect Democrats to win worry that a new majority could cut back planned increases and look harder at some Pentagon contractors' ties to the administration. Barclays analyst Anthony Valentini, starting coverage of Northrop with the equivalent of a sell rating, said there was more room for US defense spending to fall than to rise after years of growth.
The drop also reflects how far the sector had run. The aerospace and defense index gained more than 60% across 2024 and 2025, beating the S&P 500's 44% rise and the Nasdaq 100's 50%, as investors bet governments would spend more on their militaries. When expectations are that high, a shift in the political outlook can trigger a sharp reset.
Not everyone is selling. Vertical Research upgraded Lockheed to buy, arguing missile spending has support from both parties, and analyst Robert Stallard said a lot of bad news is already priced in. Citigroup analyst John Godyn flagged RTX and Huntington Ingalls as potential opportunities. Some fund managers have been adding to positions, betting the rally resumes once the election noise fades.
The longer-term backdrop has not gone away. Wars in Ukraine and Iran have highlighted demand for drones and cheaper air-defense interceptors, while US munition stocks are low. The question for investors is how much of that demand survives a change in who sets the budget in Washington.
The bull case
Defense demand rests on more than one election. Conflicts in Ukraine and Iran, depleted munition stocks and the need for new technology support orders whichever party wins, and some analysts say missile programs enjoy backing from both parties. After a near 19% drop by mid-October, valuations are lower, and several analysts argue much of the political risk is already reflected in prices.
The bear case
If Democrats win control and the proposed $500 billion spending boost fades, revenue growth expectations for contractors could fall further. Closer scrutiny of contractors' ties to the administration adds uncertainty, and a presidential election follows the midterms. The sector rallied more than 60% over two years, so there may be room for further declines if budget growth slows.
Why it matters
For investors
Large defense contractors such as Lockheed Martin, Northrop Grumman and RTX, and defense-focused ETFs, are most exposed to election-driven swings in spending expectations. Volatility could stay high through November's vote and the coming earnings season.
The wider context
Many index funds and retirement accounts hold defense stocks, which rallied strongly in recent years. The slide is a reminder that sectors tied to government spending can move sharply on politics, not just on company results.

Frequently asked questions
Why are US defense stocks falling?
Investors are betting Democrats will win November's midterm elections, which the Financial Times reported puts President Trump's proposed $500 billion military spending increase at risk. A strong two-year rally and higher fuel prices weighing on aerospace names have added to the selling.
How much have defense stocks fallen?
The S&P 1500 Aerospace and Defense Index fell nearly 19% from its early-August high through October 14, Bloomberg reported. Lockheed Martin and Northrop Grumman posted double-digit declines over that period, and the FT reported a further tumble this week.
Do Democrats cut defense spending?
Not necessarily. Some analysts say spending on areas like missiles has support from both parties, and wars in Ukraine and Iran keep demand high. The concern for investors is that a Democratic majority could slow planned increases and scrutinize contractors more closely.
