U.S. markets were rattled Tuesday as a heavy global sell-off in semiconductor stocks spread through Wall Street, crushing the year’s hottest sector and sending the S&P 500 and Nasdaq sharply lower.

The S&P 500 dropped about 1%, while the Nasdaq Composite plunged 1.5%, as investors dumped chipmakers and other tech favorites that had fueled recent gains.

The Dow Jones Industrial Average managed to hover around the flatline as defensive and consumer-oriented stocks provided some stability.

Tech’s collapse, which began on Monday, deepened overnight as Asia’s chip leaders led a rout that wiped out weeks of advances.

South Korea’s Kospi cratered roughly 10%, with memory giant SK Hynix plunging more than 12%. Japan’s Nikkei 225 also broke an eight-session winning streak, tumbling 3.5%.

The contagion quickly reached U.S. shores. Micron Technology dropped 9%, while Seagate Technology slipped over 6%. Western Digital’s Sandisk fell 12%, and Intel slid 3%.

Advanced Micro Devices and Qualcomm saw heavy losses of 5% and 10%, respectively. The VanEck Semiconductor ETF tumbled 6%, dragging the broader Technology Select Sector SPDR ETF down 3%.

Market bulls tried to find comfort in strength elsewhere. Walmart, Johnson & Johnson, and Procter & Gamble pushed higher, offsetting some of the damage. IBM jumped 4% after JPMorgan upgraded the stock to “overweight.” Sherwin-Williams and Merck also provided modest support. But those gains were nowhere near enough to counter the enormous losses in semiconductors.

Alphabet continued its slide, falling over 1% on Tuesday after a brutal 5% drop the previous session. Investors were spooked by the exodus of key artificial intelligence leaders from Google’s core teams to competitors OpenAI and Anthropic. The stock’s decline marked its worst two-day performance in more than a year.

Analysts described the sell-off as both necessary and overdue. “The AI beneficiaries are the sell-off,” said Andrew Slimmon of Morgan Stanley. “They’re not expensive, but they’re overcrowded. It’s captured the zeitgeist of momentum traders, and when that happens, you get sharp corrections like this. I’d say it’s healthy.”

Even as tech crumbled, consumer staples surged. Conagra Brands spiked 5%, while General Mills gained more than 3%. Those moves helped the S&P 500 consumer staples sector climb 1.7%, making it Tuesday’s best performer. However, Estee Lauder and Keurig Dr Pepper limited broader sector gains with small losses.

Overseas, the pain spread further. The pan-European Stoxx 600 closed down 0.6%, with its technology subindex off 3%. Semiconductor equipment maker ASMI and chipmaker STMicroelectronics led those losses, each dropping roughly 7%. Germany’s DAX and France’s CAC 40 both fell close to 1% as global investors reduced exposure to richly valued growth stocks.

Beyond equities, the broader macro picture added to investor anxiety. The conflict between the U.S. and Iran continued to destabilize sentiment, with uncertainty around the Strait of Hormuz pushing oil prices into volatile swings.

President Donald Trump announced that he would allow shipping lanes to remain open as Iran agreed to expanded nuclear inspections, but traders remained unconvinced that stability would last.

Energy Fuels, a rare earths miner, tried to buck the trend by announcing a $1.9 billion acquisition of magnetic materials firm VAC, calling it a “transformational moment” for global supply chains. Yet shares still slipped slightly, as risk appetite across the board proved weak.

Meanwhile, private markets giant Apollo disclosed that it would restrict redemptions in its retail credit fund, capping withdrawals at 5% after investors requested to redeem nearly $2.4 billion. The move underscored rising caution among institutional players who had poured into private debt as an alternative to volatile equity markets.

Adding to investor jitters, Elon Musk’s SpaceX fell below its debut price for the first time since listing nearly two weeks ago. The stock lost 4%, now down more than 26% from its peak, showing that even high-profile AI and space ventures aren’t immune to the market’s sudden tech fatigue.

Across Asia and Europe, the common theme was an unwinding of speculative bets embedded in the artificial intelligence boom. The same AI enthusiasm that drove the year’s massive run-ups in Nvidia, Micron, and Samsung has now turned into a sharp reminder of how fragile sentiment can be in crowded trades.

While some analysts remain optimistic that this correction is a “reset” rather than a collapse, the sharp reversals across multiple continents show that investors are rethinking their exposure to overhyped technology plays. The question now is whether the market truly has an appetite for valuation discipline, or if this is simply a pause before another speculative sprint.
