AI Bubble Fears Rise Amidst Tech Giants' Surge
23 Aug
Summary
- Bank of America strategist warns of an impending AI bubble bust.
- Nvidia stock shows strong growth with reasonable valuations.
- Third Point exited Nvidia but took a new stake in SpaceX.

Concerns are mounting over a potential AI bubble, with Michael Hartnett of Bank of America predicting a market bust. He highlights that upcoming IPOs, including SpaceX and potentially OpenAI and Anthropic, could further concentrate technology stocks within the S&P 500 to 48%.
Conversely, tech leader Nvidia continues to show impressive performance, with its stock up 24% in the past 52 weeks. The company has reported significant revenue growth, reaching $215.9 billion for FY26, and its cash flow acceleration is substantial. A price-earnings-to-growth ratio of 0.44 suggests its valuation remains reasonable.
Recent market movements include Dan Loeb's Third Point selling 190,000 Nvidia shares. However, this is not seen as a departure from the tech sector, as Third Point simultaneously acquired a stake in SpaceX. Nvidia, headquartered in Santa Clara, operates as a data center-scale AI infrastructure company, contributing to its strong growth trajectory.
