Stock futures slid Tuesday night after Democrats won commanding victories in key races across the country. The size of the blue wave surprised investors, many of whom had been expecting more of a ripple. S&P 500 futures that track the broad market index slid by more than 0.5%, while Dow Jones Industrial futures tumbled by more than 100 points.
Futures for the Nasdaq 100 index, which tracks the largest tech stocks, sold off by more than 1%. As results rolled in, stocks fell much further before recovering some, with Nasdaq 100 futures down at one point by as much as 2.5%. “The results signal a sharp rebuke of President Trump’s shift of focus away from economic issues and underscore voters’ insistence that Washington tackle the cost of living,” wrote Evercore’s Sarah Bianchi in a note late Tuesday, calling the outcome a “blue tsunami.” JPMorgan Chase analysts cautioned that this kind of result could trigger an “AI sell-off on assumed higher regulation.” “Possible new data-center restrictions, and higher taxes on corporations and top earners” would be “all potential headwinds for tech” companies.
On the other hand, the healthcare and clean energy industries could emerge as “relative beneficiaries” of a Democratic-controlled Congress. The JPMorgan analysts also pointed to a potential “investigation risk” facing CEOs who have close ties to President Donald Trump. Major companies ranging from Nvidia to Apple to NBC News’ parent company, Comcast, have donated millions of dollars to Trump’s pet projects, most notably his ballroom, and their leaders have regularly appeared alongside him at events.
Top Democrats have already signaled their interest in launching investigations into some of Trump’s projects in January, when their new congressional majority will give them subpoena powers. Democrats vs. data centers Tech stocks are critically important to the surge in the value of U.S. equities markets over the last two years. Trillion-dollar companies such as Amazon, Nvidia, Microsoft and Google-parent Alphabet, as well as a handful of smaller data center startups , have poured hundreds of billions of dollars into developing AI models, building data centers and buying the equipment needed to operate them.
The AI boom has also been the main driver behind the Nasdaq 100’s gains of 40% since Election Day 2024. But several Democrats who won key governors’ races on Tuesday have called for a pause in data center construction in their states, including Georgia’s Keisha Lance Bottoms and Amy Acton of Ohio. In Texas, Democrat Gina Hinojosa defeated incumbent Republican governor Greg Abbott.
More than any other state, Texas has been a major focus for AI investors and a critical market for data centers. “The one surprise that we think could plausibly spook markets is Abbott losing the TX gubernatorial election,” wrote Wolfe Research’s head of U.S. policy and politics, Tobin Marcus, in a recent note . Any widespread slowing or halting of data center construction could put those billions of dollars of investments at risk, which many of the country’s top companies have stakes in.
“Democrats winning gubernatorial races in Texas, Ohio, and Georgia—which have a significant share of the U.S. project pipeline—means new pauses and restrictions on data center development,” Bianchi, of Evercore, wrote late Tuesday. “2027 is shaping up to be a turbulent year as developers will be forced to adapt to a shifting policy landscape.” Democrats were also projected to win Senate races in a number battleground states where data centers were a major issue during the campaign, including Georgia, North Carolina, Michigan, Ohio, Iowa and Kansas. AI investors on edge Even before Tuesday’s projected results, markets had been on edge for months about whether, and how, the AI boom and the massive investments tied to it would deliver returns.
On Friday, the S&P 500 and Nasdaq both posted their worst days since mid-June after mixed earnings results from Intel and Amazon, two key suppliers to AI companies. Treasury yields also declined slightly on Tuesday night as results rolled in, which could bring near term relief to consumers seeking to borrow money or take out or refinance a mortgage. The drop in yields came as traders guessed that a slowdown in the AI sector could lead to fewer companies tapping the bond markets for additional funding.
On Monday, the Nasdaq 100 index had entered a correction, meaning a 10% drop from its most recent high. Very early Wednesday morning it remained there, and was poised to sink even further.
