Key Facts on Microsoft and OpenAI Investment

Microsoft holds a 27% stake in OpenAI, valued at approximately $135 billion at the time of the deal. OpenAI has filed for an initial public offering (IPO), with plans for a potential 2027 listing at a valuation of $1 trillion.

Despite a strong performance with an 18% revenue increase last quarter, Microsoft shares are down 19% this year, trading nearly 30% below their 52-week high. If OpenAI lists at $1 trillion, Microsoft’s stake could be worth around $270 billion, equating to roughly 9% of Microsoft’s total market capitalization of $2.9 trillion.

In Microsoft’s fiscal third quarter ending March 31, 2026, revenue reached $82.9 billion, with earnings per share climbing 23% to $4.27, and Azure revenue growing by 40%. Microsoft anticipates $190 billion in capital expenditures for 2026, which may raise concerns about short-term margins despite the strong growth prospects.
