Here’s something most index fund investors don’t think about: when you buy an S&P 500 fund, you’re not making a neutral bet on the American economy. You’re making a very specific, very concentrated bet on whatever the largest companies in that index decide to do next.

Right now, that means you’re betting heavily on Nvidia’s new strategic direction, whether you intended to or not.

The portfolio shakeup

Nvidia made headlines by completely exiting its position in Microsoft during Q1 2026. The company sold off approximately 7.7 million shares of MSFT, a full divestment that signals a meaningful change in how Nvidia views its investment priorities.

Where did the focus shift? Deeper into AI infrastructure, semiconductors, and autonomous driving. Nvidia now holds 214.8 million shares in Intel as part of its investment portfolio, underscoring a commitment to the semiconductor supply chain that powers its core business.
