Breaking: Chip stocks crash as Nvidia loses $400 billion in market value

Chip stocks led a historic rout on Wall Street on Thursday, with Nvidia losing more than $400 billion in market value in a single session. The semiconductor sector faced a severe wipeout as the Philadelphia Semiconductor Index fell more than 12 percent, marking its worst day since the market breakout in March 2020. This sharp decline capped a brutal stretch for the industry, as the index has now fallen more than 30 percent since the beginning of October and stands almost 40 percent below its peak set in June. The slide reflects a deepening anxiety among investors about the sustainability of the artificial intelligence trade that has driven market gains for years.

The damage extended across the entire chip supply chain. According to reports from BBC News and The Guardian, SanDisk fell more than 22 percent, while Western Digital dropped 17 percent. AMD and Micron each suffered losses exceeding 17 percent, and Intel was down 10.3 percent. These declines contributed to a broader sell-off in technology stocks, with the Nasdaq Composite falling 5.5 percent. The Nasdaq's drop represents its worst day in 18 months, pushing the index more than 11 percent below the record it set last month. This places the market in correction territory, a term used to describe a fall of at least 10 percent from a recent high.

The collapse in chip values occurred against a backdrop of significant political shifts. The catalyst for the selling was the Democrats' sweep of the House and Senate in Tuesday's midterm elections, as reported by CNBC. Democrats campaigned on slowing the spread of data centers and AI, and voters in several states rejected measures aimed at restricting data center development. In Texas, Democrat Gina Hinojosa won the governorship after campaigning on an immediate moratorium on new data center construction. These victories heightened concerns that the facilities at the heart of the AI build-out will face new regulatory hurdles, pressuring companies tied to the artificial intelligence trade.

For local readers in Davidson County, this market movement has tangible implications for retirement accounts and savings. While the specific companies mentioned are national or global entities, their stock performance is often linked to the broader indices that drive the value of 401(k) plans and other investment portfolios. A day like Thursday, where the Dow Jones Industrial Average fell more than 1,800 points, can cause significant volatility in these accounts. Investors holding funds that track the S&P 500 or the Nasdaq would see their balances decrease substantially. The S&P 500 fell 4.3 percent, its worst day since April 2025, when global tariffs were announced. This decline wiped out the gains made the previous day, highlighting how quickly market sentiment can shift.

Analysts are divided on the long-term impact of this crash. Neil Wilson, an investor strategist at Saxo UK, described the event as a complete capitulation-level event in tech stocks. He noted that the fear is a total momentum unwind as Democrats pace the frontier and potentially stop data center buildout. Wilson added that while the situation looks overdone, the nature of selling everything in this market means investors need to look for stability first. Dan Ives, a tech analyst, stated that there is no way to sugarcoat the fact that Democrats taking control, especially over the Senate, will create major hurdles for AI and tech legislation in the Beltway over the next two years.

The market's fear gauge, the Cboe Volatility Index, jumped as much as 5.7 points to above 28, its highest reading since March 31, 2026. The Guardian reported the VIX up 61 percent on the day. By midday, nearly 800,000 VIX call options had traded, which is 3.5 times the 30-day average. This surge in trading activity indicates that investors are aggressively hedging against further losses. Meanwhile, the 10-year Treasury yield fell to 4.83 percent, its lowest since September, as investors bought bonds as a safe haven. This move underscores the shift from risk assets to safer investments during times of high uncertainty.

Ted Parkhill, founder and chief executive of Incline Investment Management, observed that the market is moving from the promise of AI to the price of AI. He emphasized that while AI is going to be transformative for the world in the long run, it does not mean every AI-related stock is currently priced appropriately. Parkhill predicted a lot of turmoil ahead. Susannah Streeter, chief investment strategist at Wealth Club, agreed that 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 center construction.

Historical data offers some context for investors worried about the current volatility. 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. In 2018, the Nasdaq rallied the day after Democrats won the House, but a sharp December sell-off followed. The index was about 15 percent higher a year after that election. A review by CNBC of 10 Nasdaq corrections over the last decade found that while some sell-offs were followed by further rough selling, the Nasdaq was back in rally mode six months later in every case except 2022.
