Tech Stocks Tumble as Investors Question AI Spending Returns

Major tech stocks decline amid AI investment concerns

A sharp selloff in technology stocks is signaling growing investor skepticism about the financial returns from the massive spending wave on artificial intelligence infrastructure. The tech-heavy Nasdaq index dropped more than 2% as doubts mounted over whether AI investments will justify their enormous costs.

Chip maker Micron Technology led the decline with shares plunging over 13%, while established AI leaders Nvidia and Alphabet both fell for consecutive sessions. The selloff extended to other semiconductor companies, with Intel and Advanced Micro Devices each declining approximately 6%.

Why it matters

With over $1.5 trillion invested in AI over the past five years and major IPOs from OpenAI and Anthropic on the horizon, the market is demanding evidence that this capital will translate into sustainable profits. This volatility reveals a fundamental tension: while AI capabilities continue advancing, the business case for current spending levels remains unproven.

The scale of AI capital deployment

According to Stanford University's AI Index Report, corporate investment in AI reached more than $580 billion globally in the past year alone. This follows over $1 trillion invested in the four years prior, creating unprecedented valuations for AI-related companies.

Micron's stock trajectory exemplifies the market dynamics at play. The memory chip manufacturer's shares surged nearly 800% over the past year on demand from AI infrastructure buildout, only to face sharp corrections as investors reassess fundamentals.

"The market just continues to oscillate between 'AI is going to be great and increase productivity and all these companies are going to win,' and 'AI is a big waste of time and it's not worth the return on investment at all and this is all one big bubble,'" said Gil Luria, head of technology research at investment firm D.A. Davidson.

Global ripple effects

The uncertainty spread beyond U.S. markets. Korean exchanges saw significant declines after Samsung and competitor SK Hynix each dropped 12%. The Monday session had already seen Alphabet fall 5% and SpaceX decline 16%.

The timing is particularly notable as OpenAI and Anthropic prepare for what could be two of the largest initial public offerings in history. While both companies now generate revenue, the long-term profitability of generative AI remains uncertain.

"The market is trying to kind of digest all this and saying, 'Are we going to start to see returns?'" said Mark Vena, CEO of SmartTech Research.

Analysts are closely monitoring Micron's upcoming earnings report for signals about whether the AI investment cycle will maintain its current pace or begin to slow.
