Tech Stocks Lose $2 Trillion as AI Investment Skepticism Grows
The Nasdaq-100 saw an estimated $2 trillion wiped from its market value in October, as investor skepticism about the profitability of massive artificial intelligence investments grew. On the last trading day of the month, the Nasdaq Composite fell by 2.9%, marking its largest single-day drop since June. Overall, the Nasdaq experienced a decline of approximately 5.2% for the month, its worst performance since March 2025. In contrast, the S&P 500 dipped by 1.2%, while the Dow Jones, which includes many traditional companies, managed a modest gain of 1.5% in October.
Alphabet, the parent company of Google, was among the hardest hit, with its shares plummeting 12.6% on Thursday, marking the worst day in its history. This decline followed the company's earnings report, which revealed slower growth in its core search advertising business. Although search advertising revenue increased by 12%, Google executive Philipp Schindler noted that the company's AI Mode generates less revenue per search compared to traditional results. Additionally, Alphabet's heavy investments in AI infrastructure have put pressure on its cash flow, contributing to a 25% year-on-year decline in net profit, largely due to losses related to these investments. The significant drop in share price resulted in a loss of nearly $500 billion in market value for the company.

Amazon also reported negative free cash flow of $42.4 billion over the past year, primarily attributed to its AI investments, leading to a 1.4% decrease in its stock price on Friday. Chipmaker Intel faced even greater challenges, with its shares plunging 28.6%, the worst single-day performance since 1974, after it forecasted weaker profits due to difficulties in its PC and manufacturing sectors. Nvidia, known for its powerful chips used in AI systems, saw a 4.2% decline, making it the largest drag on the S&P 500, while rival AMD dropped 10.9%.
Market Analysts Warn of Continued Weakness Ahead
Market analysts are expressing concerns about the potential for further losses in the near term. Bank of America strategist Michael Hartnett predicts continued weakness until mid-November, while Morgan Stanley's Mike Wilson warns that the S&P 500 could decline further in the coming weeks before a potential recovery by year-end. The upcoming midterm elections are also expected to impact AI regulations, adding another layer of uncertainty to the market.
Investor Sentiment Shifts Towards Practical AI Financing
As tech giants continue to invest heavily in AI and data centers, projections indicate that companies like Microsoft, Meta, Amazon, and Alphabet could collectively spend over $700 billion on these long-term investments by 2026, much of which is related to AI. Estimates of global AI-related investment this year range from $900 billion to $2.7 trillion, depending on the methodology used. With companies borrowing more to finance their expansions, investor concerns are mounting.
The current market environment is characterized by a more discerning approach from investors, as highlighted by Globalt Investments senior portfolio manager Keith Buchanan. He noted that last year was marked by hope, while this year brings a focus on the practicalities of financing AI initiatives and understanding who benefits economically from these investments. The upcoming quarterly earnings reports from major players like Apple, Nvidia, AMD, and Palantir, along with Friday's jobs report, will be critical in shaping market sentiment going forward.
