Breaking: From Record Highs to Rout: Midterm Shakeout Hits AI Stocks

Wall Street closed Thursday with a sharp reversal from the previous day's record highs, as the S&P 500 fell 4.3 percent and the Nasdaq Composite dropped 5.5 percent. The Dow Jones Industrial Average, an index of 30 large US companies, lost more than 1,800 points, a decline of 3.4 percent, to end at 51,868 according to The Guardian. This session erased the gains made on Wednesday, which had seen the Dow post its biggest daily gain of the year. The selling spread through every sector of the S&P 500 and gathered pace as the day progressed, marking the index's worst performance since April 2025, the period when President Trump announced sweeping global tariffs, as reported by The New York Times.

The rout was triggered by the political shift following Tuesday's midterm elections, where Democrats secured control of both the House and the Senate. This outcome collided with existing anxieties regarding the valuation of artificial intelligence stocks. Investors are now weighing whether tighter state-level restrictions could slow data center construction, thereby pressuring companies tied to the AI trade. These concerns are compounded by broader fears that the massive sums spent on AI infrastructure may not yield the expected returns, leading to speculation that AI shares may be in a bubble, according to CNBC and BBC News.

The day before the crash, President Trump had celebrated the market's peak on Truth Social, writing that the stock market had hit another record high 91 days in a short period of time. He noted that 401(k) accounts were through the roof and that the market was record setting all around, as quoted by The Guardian. This optimism was short-lived, as the political landscape shifted dramatically with the Democratic victory. The new congressional majority is expected to create significant hurdles for AI and tech legislation in Washington over the next two years, according to Dan Ives, a tech analyst quoted by The Guardian.

Chip and AI stocks led the decline, with Nvidia falling 9.2 percent, the biggest drop among Dow components. The company lost more than $400 billion in market value, while the so-called Magnificent Seven technology companies, including Apple, Nvidia, and Tesla, shed about $1 trillion in a single day, according to BBC News. SanDisk fell more than 22 percent, and Western Digital dropped 17 percent. The Philadelphia Semiconductor Index, which tracks 30 of the largest chip companies, fell more than 12 percent, extending a decline of more than 30 percent since the beginning of October, as reported by The New York Times.

Volatility spiked across markets, with the Cboe Volatility Index jumping as much as 5.7 points to above 28, its highest reading since March 31, 2026. The Guardian reported the VIX was up 61 percent on the day, with the index moving more than 11 points from its low to its high, the biggest one-day move since April 9. By midday, nearly 800,000 VIX call options had traded, a volume 3.5 times the 30-day average, according to Cboe data cited by CNBC. The 10-year Treasury yield fell to 4.83 percent as investors sought safety in bonds, a move noted by The New York Times.

Historical data offers a mixed but generally recovering outlook for investors. Frank Cappelleri, founder of CappThesis, noted that the Nasdaq was higher 12 months after the election in all but one of 13 midterm cycles since 1974. However, he cautioned that the path can be a volatile one, pointing to 2018 as an example where a rally was followed by a sharp December sell-off before the index recovered, according to CNBC. A review by CNBC of ten Nasdaq corrections over the last decade found that while some periods saw further rough selling, the index was back in rally mode six months later in every case except 2022. On average, the Nasdaq gained 9.41 percent in the three months after a correction bottom.

Analysts are divided on the immediate impact of the political shift. Neil Wilson, an investor strategist at Saxo UK, described a complete capitulation-level event playing out in tech stocks, fearing a total momentum unwind as Democrats pace the frontier and potentially halt data center buildout. He suggested the move looks overdone but that the market needs to find stability first, as quoted by The Guardian. Susannah Streeter, chief investment strategist at Wealth Club, stated that fresh panic over the AI trade has hit Wall Street hard, with fears about infrastructure returns colliding with the prospect of a sharp slowdown in construction, according to BBC News.

Despite the panic, some strategists see a buying opportunity. Gene Goldman, chief investment officer at Cetera Financial Group, said the sell-off had become exaggerated and predicted a recovery, noting that corrections in bull markets are typically short-lived. He added that while the market is ugly right now, he expects a bounce back soon, according to The New York Times. Ted Parkhill, founder of Incline Investment Management, observed that the market is moving from the promise of AI to the price of AI, suggesting that while AI is transformative, not every related stock is priced appropriately, leading to significant turmoil, as reported by The Guardian.

The tech industry is responding to the community backlash that fueled the political shift. Greg Brockman, president and co-founder of OpenAI, said at the WSJ Tech conference that the industry had been surprised by the reaction to data centers and needed to do more to bring communities on board. He emphasized that from San Francisco, trying to build infrastructure in Texas and Georgia, one cannot just tweet that it will be good, but must be present in those communities, according to BBC News. Dina Powell McCormick, president of Meta, told the same conference that the industry needed to double and triple down on telling the story of AI to make its case more effectively.
