Quick Summary

Tech and AI stocks experienced significant declines on Friday, with the Nasdaq and S&P 500 dropping 2.4% and 1.3%, respectively, marking their worst week since July. Companies like SanDisk, AMD, and Micron saw major losses of up to 6.7%. Concerns over debt-fueled spending in data centers and unrealistic valuations have intensified, leading some analysts to predict a potential crisis of confidence in the sector. Gartner’s research indicates that AI providers will spend $7 trillion on infrastructure through 2030 but generate only $3.6 trillion in revenue, with more than 80% of neoclouds expected to fail by the end of the decade.

Story summary

As of October 16, 2026, AI and tech-related stocks experienced a significant downturn due to fears about unsustainable spending on infrastructure for artificial intelligence. The Nasdaq and S&P 500 fell by 2.4% and 1.3%, respectively, with the week set to be their worst since June. Key semiconductor companies tracked by the VanEck Semiconductor ETF saw a drop of 3.3% on Friday, with expectations for over 10% decline by week's end.

Specifically, shares in SanDisk, AMD, and Micron fell sharply by 6.7%, 5.9%, and 5.7%, respectively. CoreWeave, a major AI cloud provider, saw its stock plummet by 25% over five days, including a drop of 13.5% on Friday alone. These sell-offs reflect growing concerns that the massive $7 trillion expected to be spent on AI infrastructure through 2030 may not generate sufficient revenue, with projections indicating only up to $3.6 trillion in returns over the same period. This has raised doubts about the sustainability of current valuations and sparked fears of a broader market crisis.
