What is Microsoft’s investment story?

To own Microsoft today, you have to believe that the company can absorb significant data center and energy spending while its AI-infused cloud platform continues to grow at scale. A series of recent deals with Seneca Polytechnic, Bristol-Myers Squibb, and Mercedes-AMG Petronas F1 support that claim, but they are focused on strengthening Azure’s long-term positioning rather than driving short-term numbers alone. In the coming quarters, the real variables will continue to be Azure’s growth, Copilot’s monetization execution, and how quickly Fairwater AI data centers ease current capacity constraints. At the same time, capital spending, rising power costs, and regulatory noise surrounding OpenAI and data centers remain at the forefront of risks, especially as stock prices reflect already high expectations.

However, one risk to AI infrastructure spending and benefits is often underestimated until you look at the numbers. Microsoft stock is trending higher, but it may still be undervalued by 23%. Find out what it’s worth.
