October 30, 2026 — The Nasdaq 100 is on track to lose more than $2 trillion in market value during October as investors grow increasingly concerned about whether massive investments in artificial intelligence will generate sufficient returns.
The technology-heavy index has declined more than 5.8% this month, reflecting growing uncertainty following earnings reports from major technology companies. Meta Platforms, Alphabet and Amazon have all increased their spending projections as they race to expand their artificial intelligence infrastructure.
The potential market-value decline would exceed the entire estimated valuation of SpaceX, highlighting the scale of the pressure facing technology stocks.
Rising borrowing costs have added to investor concerns, making debt-funded infrastructure investments more expensive and raising questions about how quickly companies can recover their spending.
Technology Stocks Face a Major Selloff
Alphabet experienced its largest one-day percentage decline on record on Thursday after disappointing results in its core search advertising business and a sharp increase in cash outflows.
Meta’s plan to raise a record $97.5 billion through a stock offering has also intensified concerns about shareholder dilution and the possibility that major technology companies will increasingly depend on capital markets to finance their AI expansion.
Microsoft and SpaceX were among the exceptions, delivering results that suggested their artificial intelligence investments were beginning to generate returns.
John Bilton, global head of strategic research for multi-asset solutions at JPMorgan Asset Management, said investors may have overestimated the pace of growth but noted that aggregate demand for data continues to expand.
Big Tech’s Growing Debt Burden Raises Concerns
The financing requirements of artificial intelligence infrastructure are becoming another major issue for investors.
Microsoft is reportedly preparing to raise approximately $25 billion through its first U.S. investment-grade bond offering in more than nine years.
Meta, Amazon and Alphabet have collectively issued hundreds of billions of dollars in bonds over the past four years, prompting concerns about the technology sector’s growing reliance on debt financing.
Morgan Stanley expects total capital spending on AI infrastructure to exceed $1 trillion next year.
As borrowing costs rise, investors are increasingly questioning whether companies can maintain their aggressive investment plans without placing additional pressure on their balance sheets.
Investors Begin Pricing in AI Credit Risks
Concerns about AI spending are spreading beyond equity markets into corporate credit.
Companies that were previously viewed as relatively protected from broader economic pressures are facing greater scrutiny as their reliance on debt financing increases.
Investors are beginning to consider whether higher financing costs and slower-than-expected returns from AI infrastructure could weaken the financial position of companies leading the technology expansion.
The growing cost of protecting against potential debt defaults reflects this shift in sentiment, as markets reassess the financial risks associated with the AI investment boom.
Strong Revenue Growth Offers Some Reassurance
Despite concerns about spending, revenue across the so-called Magnificent Seven technology companies has remained strong since the launch of ChatGPT in November 2022.
Recent earnings reports have provided evidence that demand for AI-related services and digital infrastructure remains substantial.
Amazon Web Services continued to accelerate its growth, while Meta reported better-than-expected revenue expansion and issued a positive outlook. Microsoft also projected strong growth in its cloud business.
These results suggest that demand for technology services remains healthy, even as investors question how quickly the companies can translate their infrastructure investments into sustainable profits.
AI Infrastructure Spending Reaches Unprecedented Levels
Technology companies have historically invested heavily in infrastructure to expand cloud computing, online advertising and e-commerce operations. However, the artificial intelligence boom has pushed capital expenditure to unprecedented levels.
JPMorgan estimates that global AI capital expenditure could reach $5.5 trillion by 2030, with approximately $900 billion expected to be spent in 2026 alone.
The bank’s analysts also noted that the combined AI spending this year by Amazon, Alphabet, Meta, Oracle and Microsoft could equal their cumulative investment since ChatGPT launched in November 2022.
The scale of these commitments underscores how rapidly the technology industry is expanding its infrastructure to support AI development and adoption.
Investors Await the Next Wave of Earnings
With Apple’s earnings scheduled for next week and Nvidia expected to report in mid-November, investors will be watching closely for further evidence that AI investments are delivering measurable financial returns.
The central challenge facing the technology sector is balancing continued infrastructure expansion with the need to generate sufficient revenue and cash flow.
Although demand for AI services remains strong, investors are becoming less willing to support unlimited spending without clearer evidence of profitability.
The October selloff reflects a growing shift in market priorities: from enthusiasm over AI expansion toward closer scrutiny of its financial returns, funding requirements and long-term sustainability.
