Microsoft poised to attain a $4 trillion valuation
Microsoft's Azure cloud computing business reported a surge in sales on Wednesday, marking a significant milestone in the company's growth trajectory. This boom, coupled with strong earnings, indicates that Microsoft's books have yet to take a hit from US tariffs.
The company forecasts a record $30 billion in capital spending for the current fiscal first quarter, a testament to its confidence in its future prospects. Back-to-back record revenues have contributed to Wall Street's surging confidence in Microsoft, with the tech giant expected to surpass $4 trillion in market valuation for the first time on Thursday.
This growth can be attributed, in part, to Microsoft's strategic investment in OpenAI. Since the initial $1 billion investment in 2019, Microsoft's total investment in OpenAI has grown to about $13 billion. This investment has significantly boosted Microsoft's revenue and market position, particularly by enhancing its Azure cloud services with exclusive access to OpenAI’s advanced AI models.
The integration of OpenAI’s generative AI technologies has made Azure a preferred platform for AI-powered cloud services, outpacing the previous quarter’s 33% growth with a 34.8% increase in the April-June 2025 quarter. This surge has positioned Microsoft as a leader in AI-enabled cloud services, giving it a competitive edge against rivals like Amazon Web Services.
Under their agreement, Microsoft receives about 20% of OpenAI’s revenue, potentially up to $92 billion, reflecting the strategic financial importance of the relationship. However, as OpenAI prepares for a public listing, renegotiations around Microsoft’s access to IP and revenue share have introduced potential risks to this advantage.
There are ongoing tensions as OpenAI considers partnerships with other cloud providers such as Google Cloud and Oracle. The renegotiation of terms due to OpenAI’s evolving corporate structure and funding rounds introduces uncertainty about Microsoft’s future exclusivity and long-term benefits from the partnership.
Microsoft's shares rose 8% in early premarket trading, valuing it at roughly $4.14 trillion. The stock rally has been boosted by the company's focus on cementing its lead in AI technology and the success of its Azure cloud business, which is now the company's top revenue driver.
Since the debut of ChatGPT in late 2022, Microsoft's stock has more than doubled in value. Apple was last valued at $3.12 trillion, making Microsoft's impending $4 trillion valuation all the more impressive. Microsoft first surpassed the $1 trillion mark in April 2019, a milestone that now seems like a stepping stone on the way to even greater heights.
