Market Dynamics

The Vanguard S&P 500 ETF absorbed over $100 billion in inflows in 2025 as assets approach the $1 trillion mark. Information technology now accounts for roughly 34% of the fund, with Nvidia as its largest holding. That concentration means AI infrastructure spending cycles at hyperscalers now directly drive broad index performance.

Broadcom's Q1 results revealed a stark bifurcation: AI revenues jumped 106% year-over-year while non-AI segments remained flat at $4.1 billion. The divergence signals a broader pattern across tech companies where AI-related business lines are capturing all growth, creating pressure to reallocate resources and potentially restructure legacy operations.
