Breaking: Musk's $300 Billion Loss Leads Magnificent Seven's $1 Trillion Slide

Elon Musk’s companies suffered a severe financial blow on Thursday as Tesla and SpaceX lost more than $300 billion in combined value. Tesla shares fell nearly 11 percent while SpaceX shares dropped 8 percent. This decline occurred during the worst trading day for the Nasdaq Composite in 18 months, which shed 5.5 percent. The index closed more than 11 percent below its record set last month, officially entering correction territory. The selling pressure spread across every sector of the S&P 500, which fell 4.3 percent. The Dow Jones Industrial Average dropped more than 1,800 points, a 3.4 percent decline to 51,868, erasing the gains made on Wednesday.

The damage extended to the so-called Magnificent Seven technology companies, which shed about $1 trillion in value in the single trading day. This group includes Apple, Nvidia, and Tesla. Nvidia was the biggest faller in the Dow, losing 9.2 percent and more than $400 billion in market value. The Philadelphia Semiconductor Index, which tracks 30 of the largest chip companies, fell more than 12 percent. This index has fallen more than 30 percent since the beginning of October and is almost 40 percent below its peak in June. Other major chipmakers including SanDisk, Western Digital, AMD, and Micron also experienced double-digit declines.

Musk’s personal financial losses were compounded by political setbacks and spending. He had spent nearly $450 million backing Republican campaigns, including at least $45 million in support of Ken Paxton for the Texas Senate seat. That bet failed as Texas went to the Democrats on Tuesday night. The broader election results saw Democrats sweep both the House and the Senate. Voters in various states rejected data centers in a series of local ballots, with dozens of measures on ballots aimed at restricting data center development. In Texas, Democrat Gina Hinojosa won the race for governor after campaigning on an immediate moratorium on new data center construction.

Investors are now weighing whether tighter state-level restrictions could slow data center construction and pressure companies tied to the artificial intelligence trade. This concern sits on top of broader worries that the huge sums being spent on AI will not pay off and that AI shares may be in a bubble. The catalyst for Thursday’s crash was the Democrats' sweep in Tuesday's midterm elections. Investors had anticipated on Wednesday that Democratic success could restrain the White House, leading to a rally that was reversed on Thursday. The VIX, Wall Street's fear gauge, jumped as much as 5.7 points to above 28, its highest reading since March 31, 2026.

Neil Wilson, an investor strategist at Saxo UK, described a complete capitulation-level event playing out in tech stocks. He stated that the fear is a total momentum unwind as Democrats pace the frontier and kibosh data center buildout. Dan Ives, a tech analyst, said there is no way to sugarcoat that Democrats taking control will create major hurdles for AI and tech legislation. Ted Parkhill, founder of Incline Investment Management, noted that the market is moving from the promise of AI to the price of AI. He added that while AI is transformative, not every AI-related stock is currently priced appropriately, and there will be a lot of turmoil.

Susannah Streeter, chief investment strategist at Wealth Club, said fresh panic over the AI trade has hit Wall Street hard. She explained that fears that vast sums poured into AI infrastructure may not deliver returns are colliding with the prospect of a sharp slowdown in data center construction. Gene Goldman, chief investment officer at Cetera Financial Group, said the sell-off had become exaggerated but predicted a recovery. He noted that corrections in a bull market are typically short-lived and that investors should expect a bounce back soon. Frank Cappelleri, founder of CappThesis, pointed out that the Nasdaq was higher 12 months after the election in all but one of 13 midterm cycles since 1974, though the path can be volatile.

The tech industry responded to the backlash with statements emphasizing community engagement. Greg Brockman, president and co-founder of OpenAI, said everyone had been surprised by the reaction to data centers. Speaking at the WSJ Tech conference in Napa, California, he stated that from San Francisco trying to build infrastructure in Texas and Georgia, one cannot just tweet and say it is going to be good. He emphasized the need to be in those communities. Dina Powell McCormick, president of Meta, told the same conference that the industry needs to double and triple down on telling the story. The 10-year Treasury yield fell to 4.83 percent as investors bought bonds as a haven.

In London, the FTSE 100 closed down 46 points, or 0.4 percent, at 10,782.66, after an early rally in Europe fizzled. The S&P 500’s worst day since April 2025, when President Trump announced sweeping global tariffs, marked a significant shift in investor sentiment. The Nasdaq’s decline puts it in correction territory, defined as a fall of at least 10 percent from a recent high. A 20 percent fall would constitute a bear market. The estimated $2.5 trillion in market value wiped from the Nasdaq Composite highlights the scale of the adjustment. Investors are now looking for stability after the rapid selling accelerated through the day.
