Nvidia and Broadcom Face Investor Scrutiny Over AI Spending and Market Concentration

Investors are growing more cautious about the scale of AI-related capital spending and the transparency of revenue tied to it, putting pressure on shares of Nvidia, Broadcom and other technology companies. Nvidia's data-center demand remains robust, with quarterly revenue around $96 billion and management saying supply is still short of demand, but questions persist about whether the boom can produce durable profits. The rally's heavy reliance on a small group of tech names is also drawing attention, as most S&P 500 constituents trade well below their records even while the index sits near highs.

Nvidia's latest quarter brought about $96 billion, more than double a year earlier, with data-center sales driving most growth. Management says demand exceeds supply and expects substantial growth into fiscal 2028; the Vera Rubin platform is intended to expand AI computing capacity. Nvidia also has roughly $279 billion in future supply obligations and has backed AI developers and customers, while higher memory costs pressure gross margins.

Broadcom is deepening ties with major AI developers, including a reported $42 billion financing package with Anthropic. Market breadth remains narrow: 84% of S&P 500 members sit at least 10% below records even as the index nears highs. Nvidia reportedly held preliminary talks with Reflection AI about a deeper investment or possible acquisition.
