Democratic Congress Win Hits Chip Stocks; Trump Veto Limits Real Damage

Chip and technology stocks sold off across the board after the Democratic Party's victory in the US midterm elections, and the market's nerves trace back to one question: will Washington now slow the massive buildout of AI infrastructure?

Swissquote, which published the analysis on TradingView tied to the S&P 500, argues the fears are real but exaggerated. The market is worried that Democratic legislative initiatives — at both federal and local levels — could call into question or delay the huge investment plans flowing into AI compute.

The concerns break down into two channels, the Swiss bank notes:

• Federal legislative action against AI in the US Congress, now under a Democratic majority.
• Local action by Democratic officials across individual states and municipal authorities targeting the physical deployment of AI infrastructure.

Both risks exist. Neither, on Swissquote's reading, is likely to break the sector's structural momentum.

Can Democrats actually pass anti-AI laws?

The first constraint is presidential power. Donald Trump holds the veto over any legislation Congress passes. To override that veto, Democrats would need a two-thirds majority in both chambers — a particularly difficult threshold given they hold only a simple majority. The president can therefore block any potential bill imposing a nationwide moratorium on new data centers or adding new legal restrictions on the sector.

The second constraint is political coherence. Swissquote points out there is no unified Democratic push to undermine AI momentum in the United States. Add a Republican minority in Congress with its own procedural tools, and the White House, and the obstruction levers remain powerful on the other side.

Where does the real risk sit?

The answer, according to the analysis, is local. State and local government powers are probably the risk that Washington will find most difficult to neutralize.

Local authorities control urban planning, zoning and building permits. They can reject individual projects, impose additional requirements, or temporarily suspend new developments. Environmental constraints, water consumption and the substantial electricity requirements of data centers all offer further grounds for opposition. And the US president cannot simply overturn a municipal decision to deny a building permit with a veto.

There is also a quieter pressure channel. A Democratic-controlled Congress can hold hearings, open investigations into major technology companies and turn budget debates into friction. None of this requires new legislation, but all of it can raise regulatory uncertainty and complicate initiatives coming from the Trump administration.

What does it mean for hyperscaler capex?

For financial markets, Swissquote draws a sharp line between two different risks. The first is a widespread federal blockade — constrained by presidential veto power. The second is operational delay to individual infrastructure projects.

Microsoft, Amazon, Alphabet and Meta, the analysis concludes, could well maintain their massive investment budgets while facing greater difficulty obtaining permits, securing electricity connections and accessing the capacity their new data centers require. In other words: the money keeps flowing, but the concrete pours slower.

The political shift in the United States therefore represents an additional risk factor for the deployment timeline of AI infrastructure — but not necessarily for the structural investment momentum in the sector, Swissquote writes.

For equity markets, the main task ahead is monitoring the gap between the capex the hyperscalers announce and the computing capacity they actually commission. That spread, not the election result itself, will tell investors whether politics is genuinely biting.
