Microsoft's $170B Capex Plan Is Great News for Nvidia

Microsoft reported its fiscal 2027 first-quarter earnings this week, and the spotlight was on capital expenditures (capex). The tech giant revealed that about 75% of its Q1 capex went toward 'short-lived assets,' primarily CPUs and GPUs. This is a significant detail because it shows where Microsoft is directing its AI infrastructure investments.

More importantly, Microsoft forecasted $170 billion in capex for the calendar year and expects capex to accelerate in the second half, again driven by spending on CPUs and GPUs. This acceleration is based on ongoing high demand, indicating that Microsoft is building to serve a trend that is already in place, not a speculative future.

Nvidia, as the leading provider of GPUs for AI, stands to benefit directly. Microsoft is one of Nvidia's largest customers, and its commitment to heavy GPU spending validates the strong demand for Nvidia's products. This comes at a time when some investors have worried about a potential slowdown in AI spending.

Nvidia's stock has climbed over 1,100% in the past three years but is only up 15% this year, as concerns about tech spending weighed on performance. Microsoft's announcement provides a counterpoint to those worries, suggesting that demand remains robust.

For Nvidia shareholders, Microsoft's capex plans are a strong vote of confidence. Data center sales make up 92% of Nvidia's total revenue, so any signal about the health of AI infrastructure spending is critical. Microsoft's plan to accelerate capex, with a focus on GPUs, directly supports Nvidia's growth trajectory.

This news helps alleviate fears that tech giants might be overspending or that AI demand could wane. Instead, it confirms that demand is strong enough to justify massive investments. For Nvidia, this means its earnings could continue to grow, potentially driving the stock higher.

Additionally, Microsoft's mention of CPUs is noteworthy. Nvidia recently launched its first stand-alone CPU, and Microsoft's spending on CPUs could open a new growth avenue for Nvidia. While GPUs remain the core, CPUs for AI agents represent an expanding opportunity.

Overall, this reinforces Nvidia's competitive position and suggests that the AI boom is far from over. Investors who were worried about a slowdown now have tangible evidence that the largest players are still spending heavily.
