AI Data Center Stocks Drop as Democrats Win Texas and Congress

AI data center stocks fell overnight after Democrats flipped both the House and the Senate in the November 3 midterm elections and won the Texas governor's race. Texas holds 27% of planned US data center gigawatts, according to Wells Fargo, and its incoming governor has called for a moratorium on new AI data centers. Investors moved quickly to price the risk that the build-out behind the AI trade gets slower and more expensive.

The first reaction was sharp. Nasdaq-100 futures fell as much as 2.4% and S&P 500 futures as much as 1.4% as results came in, Reuters reported. By Wednesday morning the picture had changed: Dow futures were up 724 points, or 1.4%, and S&P 500 and Nasdaq-100 futures were up about 1%, according to CNBC. The selling concentrated in the companies that build and rent out AI capacity, not in Big Tech.

Texas turned a policy fight into a market event

Democrat Gina Hinojosa defeated Governor Greg Abbott, becoming the first Democratic governor of Texas since Ann Richards left office in 1995, CNBC reported. Hinojosa campaigned for a pause on new data center projects until the state adopts tougher rules and for an end to related tax incentives. The state Legislature stays in Republican hands, which limits how fast any moratorium could become law.

The exposure is large. Wells Fargo estimates Texas accounts for 27% of planned US data center gigawatts, with Georgia at 7% and Ohio and Pennsylvania at 5% each. JLL, cited by CNBC, projects Texas will overtake Virginia as the world's largest data center market by 2030. Before the vote, Wells Fargo chief equity strategist Ohsung Kwon framed the stakes plainly.

Voters appear to have cared. In a CNBC Voter Poll, 56% said data centers were a crucial or major factor in their decision, and Democrats ranked the issue higher than Republicans did. Local opposition was already slowing projects: Data Center Watch counted at least 45 projects worth $68 billion disrupted in the second quarter of 2026, according to Investing.com.

Neocloud and chip stocks took the hit

The companies most tied to new capacity fell first. CoreWeave dropped between 3% and 4% in premarket trading, according to Investing.com and CNBC, and Applied Digital fell 3%, Investing.com reported. Evercore ISI analyst Amit Daryanani told clients the reaction would be to sell AI names. Dan Ives of Yorkville Ives & Co. said the result would slow the pace of data center buildouts across the US. We looked at why these names are so sensitive to financing and timing in our analysis of neocloud stocks and debt.

Asia sold chip equipment and memory hard. SoftBank Group and Advantest each fell more than 8%, Tokyo Electron dropped 7.04% and SK Hynix lost 5.08%, CNBC reported. Japan's Nikkei 225 was down more than 4% during the session before closing 1.42% lower.

Big Tech held up, and Musk's companies did not

The largest AI spenders traded higher before the open. Nvidia, Alphabet, Meta and Microsoft were each up about 1% to 2% in premarket trading, and Amazon rose 2.7%, CNBC reported. AMD gained about 6% after earnings that beat estimates. These companies can build in many states and countries, which makes a single state's policy less of a threat to them than to a neocloud with sites concentrated in Texas.

SpaceX fell 4.6% and Tesla 4.4% in premarket trading after candidates backed by Elon Musk lost. CNBC reported Musk spent at least $474 million on the midterms, including $224 million in Texas, where SpaceX is building several gigawatts of data center capacity.

Some strategists see the result as a check rather than a threat. Several told CNBC that markets tend to welcome divided government, and any new federal rule on data centers would still need President Trump's signature. CNBC's own analysis found the S&P 500 rose in the year after each of the last 11 midterm elections, by 13.7% on average.

What the AI Bubble Index says

The AI Bubble Index read 63.3 at the November 3 close, before the results, in the Normal band and down from 64.4 a week earlier. Fragility, at 72.2, sits well above Euphoria at 62.8, and the systemic risk family reads 71.8. Sentiment and attention remains the hottest family at 92.8, while the demand gap is the coolest at 39.6. The long-run core, which compares today with every day since 1990, stands at 80.1. Follow each component on the dashboard.

The reading does not yet include Wednesday's session. Political risk to data centers is a new kind of pressure on the demand story, and it adds to the risks Bank of America described in its warning about an AI sell-off.
