Breaking: Musk's $300B Loss and the $1T Tech Wipeout

The S&P 500 fell 4.3 percent on Thursday, marking its worst day since April 2025 when President Trump announced sweeping global tariffs. The selling spread through every sector of the index and gathered pace through the trading day, erasing the gains made on Wednesday. For savers and 401(k) holders, the decline represents a significant hit to portfolios that had recently seen record highs. The Nasdaq Composite fell 5.5 percent, its worst day in 18 months, and closed more than 11 percent below the record it set last month. This drop places the index in correction territory, defined as a fall of at least 10 percent from a recent high. An estimated $2.5 trillion in market value was wiped from the Nasdaq Composite, according to Dow Jones data cited by the BBC.

The so called Magnificent Seven technology companies, which include Apple, Nvidia and Tesla, shed about $1 trillion in value in the single trading day. This massive loss highlights the concentration of risk in the current market structure. Elon Musk faced a particularly bad week as his companies took a direct hit. Tesla fell nearly 11 percent and SpaceX fell 8 percent, taking more than $300 billion off the value of his companies. Musk 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 catalyst for the sell off was the Democrats sweep of the House and Senate in Tuesday midterm elections. Democrats in races across the country campaigned on slowing the spread of data centers and AI. There were dozens of measures on ballots around the country aimed at restricting data center development, and voters rejected data centers in a series of local ballots. In Texas, Democrat Gina Hinojosa won the race for governor after campaigning on an immediate moratorium on new data center construction. Democratic victories in states with large concentrations of planned data centers, including Ohio and Texas, heightened concerns that the facilities at the heart of the AI build out will face new hurdles.

Nvidia fell 9.2 percent, the biggest faller in the Dow, losing more than $400 billion in market value. SanDisk fell more than 22 percent while Western Digital fell 17 percent. AMD and Micron each fell more than 17 percent and Intel fell 10.3 percent. The Philadelphia Semiconductor Index, which tracks 30 of the largest chip companies, fell more than 12 percent. It has fallen more than 30 percent since the beginning of October and is almost 40 percent below its peak in June. The iShares Semiconductor ETF fell 12 percent, its worst day since the Covid 19 breakout in March 2020.

Wall Street fear gauge, the Cboe Volatility Index, jumped as much as 5.7 points to above 28 about 90 minutes after the opening bell. This was its highest reading since March 31, 2026. From its low to its high the VIX moved more than 11 points, its biggest one day move since April 9. By midday nearly 800,000 VIX call options had traded, 3.5 times the 30 day average. The 10 year Treasury yield fell to 4.83 percent, its lowest since September, 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.

Neil Wilson, investor strategist at Saxo UK, said a complete capitulation level event was playing out in tech stocks. He noted that the fear is a total momentum unwind as Democrats pace the frontier and kibosh data centre buildout. Wilson added that this looks totally overdone but the nature of sell everything in this market means we need to look for some stability first. Dan Ives, tech analyst, said there is no way to sugarcoat that Democrats taking control, especially over the Senate, will create some major hurdles for AI and tech legislation in the Beltway over the next two years. He said the midterm results are a clear sign the pace of data center build out will start to slow.

Ted Parkhill, founder and chief executive of Incline Investment Management, said the market is moving from the promise of AI to the price of AI. He noted there is no question that AI is going to be transformative for the world in the long run, but that does not mean every AI related stock is currently priced appropriately. Parkhill predicted there is going to 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 noted that fears that the vast sums poured into AI infrastructure may not deliver the returns investors have been banking on are now colliding with the prospect of a sharp slowdown in data centre construction.

Gene Goldman, chief investment officer at Cetera Financial Group, said the sell off had become exaggerated as selling accelerated through the day. He predicted a recovery and stated that when you have a correction in a bull market they are typically short lived. Goldman added that it is ugly right now but we do think we will see a bounce back soon. Frank Cappelleri, founder of CappThesis, said the Nasdaq was higher 12 months after the election in all but one of 13 midterm cycles since 1974. However, he noted the caveat is that the path can be a volatile one. In 2018 the Nasdaq rallied the day after Democrats won the House, a sharp December sell off followed, and the index was about 15 percent higher a year after the election.
