Big Tech loses billions as AI spending concerns weigh on valuations

Summary

Major technology companies have shed significant market value in early 2026 as investors reassess whether aggressive spending on artificial intelligence will translate into sustainable profits. The shift reflects growing focus on earnings discipline and monetisation timelines.

The world’s largest technology companies have seen hundreds of billions of dollars in combined market value eroded in early 2026, as investors reassess whether aggressive spending on artificial intelligence will deliver durable returns.

After years of strong gains driven by AI optimism, markets are showing signs of caution, with analysts pointing to rising capital expenditures, intensifying competition, and uncertainty over monetisation timelines.

AI spending under scrutiny

Shares of Microsoft have fallen in the mid-teens percentage range year-to-date, trimming a substantial portion of its market capitalisation and leaving the company valued just below recent highs. Investors are weighing risks tied to its AI strategy and growing competition across the generative AI ecosystem.

Amazon has also declined notably, with the company signaling sharply higher capital spending as it expands AI and cloud infrastructure.

Meanwhile, Nvidia, Apple, and Alphabet have each experienced periods of valuation pressure as investors digest the scale of industry investment required to sustain AI growth.

Shift in market psychology

The pullback reflects a broader change in investor sentiment. Markets that once rewarded long-term AI ambition are increasingly demanding clearer evidence of revenue growth and profitability.

Rising competition — including rapid advances in AI models and enterprise automation — has added pressure, prompting investors to question whether current valuations fully account for execution risks.

Winners emerge outside Big Tech

Not all companies are facing the same pressure. Some firms, including TSMC, Samsung Electronics, and Walmart, have added market value this year, suggesting capital is rotating toward businesses seen as beneficiaries of AI demand or offering defensive growth characteristics.

Why this matters

The sell-off underscores a critical phase in the AI investment cycle: markets are shifting from enthusiasm to scrutiny. The ability of technology giants to convert massive infrastructure spending into reliable revenue streams will likely shape market leadership in the coming decade.
