- Tech stocks tied to the artificial intelligence boom tumbled again, dragging the Nasdaq about 2% lower and hammering chipmakers from California to South Korea as investors opt to sell.
- Sky-high valuations, massive data-center spending and mounting geopolitical and economic risks — including the war with Iran and rate hike fears — are fueling questions about an AI-fueled market bubble.
- Yet AI adoption keeps surging, startups such as OpenAI and Anthropic eye stock-market debuts and investors brace for Micron’s earnings in what analysts call a “white-knuckle” gut-check for tech.
Tech stocks took another big hit Tuesday as investors sold off shares of companies that have powered the artificial intelligence boom.
Technology companies have been spending billions of dollars investing in data centers and infrastructure needed to support the race to advance AI. But sky-high valuations and geopolitical tensions have some investors questioning whether massive AI spending will pay off, analysts said.
SpaceX stock was hovering around $160 a share on Tuesday, returning to its closing IPO price after a run-up that raised shares 40% since the company went public.
Reflecting the unease, the tech-heavy Nasdaq composite dropped roughly 2%. The Standard & Poor’s 500, a stock market index that tracks the performance of the largest U.S. publicly traded companies, fell by more than 1%.
Share prices for major California tech companies including Nvidia, Qualcomm, Intel and Marvell Technology all dropped. Meta Platforms, Apple, and Google’s parent company, Alphabet, also saw their stock prices slide, though the decline wasn’t as large as the drop in chip stocks.
Shares of Micron Technology, a U.S. memory chip manufacturer, plunged by more than 13% a day before the company was scheduled to report its third-quarter financial results. Anxiety in the U.S. spilled over from Asia, where South Korean tech companies SK Hynix and Samsung Electronics, both major computer memory chip manufacturers, saw their stocks plunge Tuesday by more than 12%.
“Investors are just a bit skittish after very strong moves in tech stocks where any hint of caution causes some investors to hit the sell button,” said Dan Ives, an analyst who heads technology research at Wedbush Securities, adding that it’s a “gut-check moment.”
On Monday, SpaceX saw its shares plunge 16% after a record-breaking initial public offering this month. Its share price then rebounded Tuesday, closing up less than 1% to roughly $156.
SpaceX is seeking to sell 555 million shares at $135 each, raising $75 billion and valuing the rocket maker at $1.77 trillion — making it one of the largest public companies.
Tech companies have been making big bets on the role AI will play in people’s work and personal lives. They’ve been improving chatbots that can generate code, words, photos and videos. The companies also are betting that “AI agents” will be able to proactively tackle more in the future, automating repetitive tasks in customer service, online shopping and other industries. They’re releasing more AI-powered hardware such as smartglasses.
AI firms are staging IPOs to collect billions in capital. But where is the money coming from--or going?
Major tech companies are going head-to-head in the race to dominate AI, competing to sway talent and consumers into using their products. Alphabet saw its stock slip after two of the company’s prominent AI researchers left for rival companies OpenAI and Anthropic.
Despite profitability questions, AI use has been growing. Roughly half of U.S. adults use an AI chatbot, according to a Pew Research Center report released this month. They’re using these tools for search, work tasks, entertainment and even companionship. More U.S. adults reported using OpenAI’s ChatGPT, followed by Google’s Gemini, Microsoft Copilot and Meta AI.
Amid all the hype and spending, there also have been growing fears about whether AI will take over people’s jobs and whether the boom will lead to a bubble that will eventually burst. California AI startups OpenAI, valued at $852 billion, and Anthropic, valued at nearly $1 trillion, are preparing to potentially become publicly traded companies.
“I don’t view this as a bubble,” Ives said. “I view it as we’re going to go through these white-knuckle moments as tech stocks continue to move higher, but the bears will continue to yell fire in a crowded theater when we have these pullbacks.”
Investors are worried that tech companies are overspending on artificial intelligence and there’s a bubble that could burst.
Economic factors also could affect how much people are willing to invest in tech company stocks. There’s anxiety over whether the new Federal Reserve Chair Kevin Warsh will raise interest rates, making it more expensive to borrow money. That could cut into a company’s profit margin or decrease consumer spending. United States’ war with Iran is driving up gas prices while the U.S. inflation rate rose to 4.2% in May.
The AI boom is fueling the demand for memory and storage chips, but prices for them are on the rise, prompting some companies such as Apple to look at raising prices for consumer electronics.
Globally, AI spending is projected to increase to $2.59 trillion in 2026, up 47% year over year, according to a forecast by research firm Gartner.
Driven by AI demand, memory and storage vendors have significantly outperformed the S&P 500 and the SOX index, a global semiconductor and microchip index, since the start of 2025, according to a note to clients from BNP Paribas.
Still, investors are on edge ahead of Idaho-based Micron Technology’s earnings report Wednesday, said Gil Luria, head of technology research at financial services company D.A. Davidson. Since January, Micron Technology’s stock has climbed more than 233% to more than $1,000 per share.
“Any indication of a slowdown in demand for AI is seen as a potential turn in the cycle,” Luria said. “While the overwhelming sense is that demand is still far exceeding supply, investors are waiting for Micron to indicate that is still the case.”
