Artificial intelligence (AI) has been a driving force behind the recent success of tech giants like Microsoft, Meta, and Nvidia. However, the landscape has shifted in 2026, with Wall Street questioning the justification for the massive capital expenditures these companies are making to expand their AI capabilities. As a result, the stocks of these three companies have all faced declines, with Microsoft down 21%, Meta down 10%, and Nvidia down 7% so far this year.

Why it matters

The performance of these mega-cap tech stocks is a bellwether for the broader tech industry. Their struggles highlight the challenges of navigating the rapidly evolving AI landscape, where the winners and losers are not yet clear. Investors are grappling with how to position their portfolios as the tech sector faces increased scrutiny and uncertainty.

The details

Microsoft has faced criticism for its $37.5 billion in capital expenditures, two-thirds of which went to hardware to support AI, such as Nvidia's GPUs. However, the company sees this as a key investment in its future growth, as it seeks to expand its cloud computing capacity to meet customer demand for AI. Meta, meanwhile, has forecast its capex to reach between $115 billion and $135 billion in 2026, up from $72.2 billion in 2025, as it invests to capture AI demand. Nvidia, the leading provider of GPUs for AI, is seen as a key beneficiary of the AI revolution, but its stock has also faced a sell-off as Wall Street struggles to predict the winners and losers in the rapidly evolving AI landscape.
