Microsoft just doubled down on artificial intelligence. The tech giant on Tuesday said it’s extending and deepening its partnership with OpenAI, buying about 27% of the company that makes ChatGPT. Investors greeted the news warmly, sending Microsoft’s stock up as much as 3% at market open and bringing the company closer to its all-time high.
The announcement represents a milestone in Microsoft’s AI plan. The stock price of the company spiked to an intra-day high of $553.72, only 0.3% off its record high of $555.45 established last July.
More significantly, Microsoft surpassed the $4 trillion market capitalization barrier for the second time this year, a reflection of Wall Street’s faith in its AI-fueled future.
How Strategic Exclusivity and AGI Goals Define the Microsoft-OpenAI Partnership?
Microsoft’s roughly 27% stake in OpenAI Group PBC, including shares owned by employees, investors, and the OpenAI Foundation, is worth around $135 billion at current valuations, a staggering sum that represents both the runaway growth of the AI industry as well as Microsoft’s early wager on the technology.
The increased partnership arrives as OpenAI is experiencing a dramatic shift, becoming a public benefit corporation. This new structure lets the AI company seek profitability while still following the mission set down by its founders to make artificial intelligence work for all humanity.
In addition to the header share percentage, the agreement includes a number of strategic provisions that insulate Microsoft from competitive disadvantages while providing OpenAI with more autonomy to operate than it had previously.

Microsoft gained important exclusivity rights that safeguard its investment. The firm maintains exclusive intellectual property and Azure API exclusivity until OpenAI reaches artificial general intelligence, that watershed moment when AI has the ability to do any intellectual task a human can. Even after AGI, some rights will persist through 2032.
OpenAI’s $250 Billion Azure Commitment Comes with New Freedoms
Microsoft also holds research IP rights until AGI verification or 2030, whichever comes first. Most importantly, consumer hardware IP is excluded from these agreements, which grants OpenAI flexibility to create devices or collaborate with hardware vendors on its own.
The pact also involves a huge commitment on the part of OpenAI to buy a further $250 billion of Azure cloud computing, a bonanza for Microsoft’s already overwhelming cloud computing division. But there is a major change from previous deals: Microsoft no longer has the right of first refusal as OpenAI’s sole compute provider, allowing the AI startup greater freedom to seek computing power elsewhere.
The revised pact grants OpenAI much more autonomy than earlier deals. The startup is now able to work with other firms on different products, but API-based products need to be exclusive to Microsoft Azure. What that implies is that OpenAI can develop consumer apps with partners but keep the underlying API infrastructure locked to Microsoft’s cloud platform.
Microsoft and OpenAI Balance Strategic Partnership with AGI Competition
In a very interesting twist, Microsoft now has the ability to pursue AGI development independently of OpenAI, either individually or with other parties, subject to specific compute and safety requirements. This provision essentially enables the two companies to compete towards the same groundbreaking objective while still being strategic partners.
OpenAI also obtained the right to publish open-weight AI models and offer API access to U.S. national security clients irrespective of their cloud provider, a significant concession that acknowledges AI’s increasing value to national defense and security.
Market reaction was strongly positive. Retail sentiment on Microsoft moved higher within “bullish” territory, with conversation volume spiking from “normal” to “high” levels in the last day. Microsoft shares have rallied 28% year-to-date and about 26% in the last 12 months, far surpassing many peers in the technology sector.
Interestingly, OpenAI retail sentiment while not listed it was still in “bearish” territory. It might be because of apprehensions regarding the startup’s route to profitability or uncertainty over its corporate structure shift.
The renewal of the partnership confirms Microsoft’s initial bet on OpenAI and puts the company well-positioned to hold pole position in the highly competitive AI race. As both entities strive towards AGI, this broadened deal guarantees they’ll proceed in unison while maintaining sufficient autonomy for each to have independent initiatives when strategic imperatives call for it.
