U.S. stock futures slid sharply early Wednesday as Democrats secured projected control of both chambers of Congress, with Nasdaq-100 futures falling nearly 2% on fears that a Democratic majority would restrict data-center construction and curb the AI buildout.
Investors with exposure to semiconductor and hyperscaler infrastructure names face a potentially durable headwind: a Democratic-controlled Congress could impose nationwide moratoriums on data-center permitting, threatening the capital-spending cycle that has underpinned AI-linked earnings growth through 2026.
Key Takeaways
- Nasdaq-100 futures fell nearly 2%; VIX futures topped 20.
- Democrats projected to win House, Senate, and Texas governorship.
- Solar ETF (TAN) surged 3%; chip ETF (SMH) retreated.
Market Reaction & Context
As of late Tuesday evening, S&P 500 futures were down roughly 1.1%, Dow futures shed 0.76%, and Nasdaq-100 futures fell close to 2% – off their session lows but still markedly weaker than the flat-to-higher open that preceded the first vote tallies 1. The Cboe Volatility Index futures, Wall Street’s so-called fear gauge, rose above 20.90, a level that historically signals elevated investor anxiety 2.
Asia-Pacific markets amplified the selling. Japan’s Nikkei 225 plunged 4.45% to its lowest close since May, while SoftBank Group (9984.T) dropped more than 8% and chipmaking equipment maker Disco (6146.T) fell 10.19% 2. South Korea’s SK Hynix shed 5.08% and Samsung Electronics declined 3.87%, while Taiwan’s TSMC slipped 1.09%.
The Texas Wildcard: Data-Center Geography
The race that rattled AI investors most was not in Washington but in Austin. The Associated Press projected Democratic candidate Gina Hinojosa the winner over Republican incumbent Greg Abbott in the Texas gubernatorial contest; Hinojosa has pledged an immediate moratorium on new data-center construction in the state 2.
Texas accounts for roughly 27% of U.S. data-center gigawatts, according to Wells Fargo estimates, making the state an outsized factor in hyperscaler capacity planning 2. “If Abbott were to lose, I think that fertile ground is largely barren,” said Scott Ladner, chief investment officer of Horizon Investments. “So that’s going to be a challenge. And so the AI trade – at least for the next couple of days – does hinge on does Abbott win or not.”
SpaceX shares fell more than 6% in overnight Robinhood trading, while Tesla slid more than 4%, as both companies relocated their headquarters to Texas from California in 2024 partly to operate under a more business-friendly regulatory regime 2.
Sector Divergence: Chips Down, Solar Up
Not every sector retreated. The Invesco Solar ETF (TAN) gained 3% in extended trading, with options volume surging to 40 times its recent daily average – 99% of the roughly 20,000 contracts traded on Tuesday were calls, according to Cboe LiveVol data 2. Investors bet that a Democratic Congress would reverse Trump administration policies that had curtailed renewable-energy incentives.
On the chip side, Nvidia (NVDA) fell about 1.5% in overnight trading, Micron Technology (MU) and Broadcom (AVGO) each dropped roughly 3%, and the leveraged Direxion Daily Semiconductor Bull 3X Shares (SOXL) plunged nearly 8% 2. The Roundhill Magnificent Seven ETF (MAGS) and the iShares Semiconductor ETF (SOXX) were each off more than 2%.
Trump Media & Technology (DJT) tumbled more than 7% in overnight trading after CNBC’s Election Desk projected Democratic control of the House, with the Senate shortly following 2.
Earnings Provide a Partial Offset
Advanced Micro Devices (AMD) initially surged double digits in post-market trading Tuesday after the chipmaker reported record third-quarter revenue of $13.4 billion – up 45% year-over-year – and guided fourth-quarter sales to roughly $17 billion, which would, if achieved, mark the first quarter in which AMD outsells Intel on a revenue basis 2. The stock pared gains to about 5% higher by the time broader futures had turned lower.
Super Micro Computer (SMCI) jumped more than 9% after first-quarter revenue nearly quadrupled to $20 billion, while Arista Networks (ANET) gained 12% on above-consensus fourth-quarter guidance of $3.9 billion to $4.0 billion in revenue 2. Those results offered some reassurance that enterprise AI infrastructure spending has not yet stalled, even as political risk clouds the longer-term outlook.
Outlook
President Donald Trump appeared to soften any potential market shock, telling The Wall Street Journal: “I think we’ll work with the Democrats, and we’ll get along very well with them” 1. That comment helped futures pull back from their worst levels of the session.
Anthony Saglimbene, chief market strategist at Ameriprise Financial, cautioned that the broader concern extends beyond data centers. “If you get some governorships that are Democratic, what does that mean for the data center buildout, which has already seen a lot of skepticism over the last couple weeks in terms of the hyperscaler capex spending?” Saglimbene said 2.
History offers some comfort to long-horizon investors: the S&P 500 has risen after each of the last 11 midterm elections, returning an average of 13.7% one year out, according to a CNBC analysis of data from 1982 to 2022 2. Edward Jones senior strategist Angelo Kourkafas said any election-driven volatility “may present an opportunity for long-term investors to lean into it.”
Conclusion
The 2026 midterm results inject a new layer of regulatory uncertainty into AI infrastructure names at a moment when hyperscaler capital-expenditure growth was already under scrutiny. Retail investors holding chip, data-center, or AI-adjacent equities should monitor Congressional committee assignments and any early legislative signals on data-center permitting for the clearest read on how durable this political headwind proves to be.
