OpenAI seems to be on a roll with high-profile partners, after recently announcing a mega multi-billion dollar deal with Oracle, it has now announced a partnership with software giant Microsoft.
Microsoft and OpenAI’s joint statement from Microsoft’s blog:
“Microsoft and OpenAI have signed a non-binding memorandum of understanding (MOU) for the next phase of our partnership. We are actively working to finalize contractual terms in a definitive agreement. Together, we remain focused on delivering the best AI tools for everyone, grounded in our shared commitment to safety.”
OpenAI also announced it is now operating as a Public Benefit Corporation (PBC). A PBC is a for-profit company that, unlike traditional corporations focused solely on maximizing shareholder value, must also consider its stated public benefit in decision-making. By law, PBCs are required to balance financial returns with their social or environmental mission and typically publish public reports demonstrating progress toward those goals.

OpenAI’s planned evolution will see the existing OpenAI nonprofit both control a Public Benefit Corporation (PBC) and share directly in its success.
OpenAI said on its website: “As previously announced and as outlined in our non-binding MOU with Microsoft, the OpenAI nonprofit’s ongoing control would now be paired with an equity stake in the PBC. Today, we are sharing that this new equity stake would exceed $100 billion—making it one of the most well-resourced philanthropic organizations in the world. This recapitalization would also enable us to raise the capital required to accomplish our mission—and ensure that as OpenAI’s PBC grows, so will the nonprofit’s resources, allowing us to bring it to historic levels of community impact.”
As part of this next phase, the OpenAI nonprofit has launched a call for applications for the first wave of a $50 million grant initiative to support nonprofit and community organizations in three areas: AI literacy and public understanding, community innovation, and economic opportunity.
The evolving partnership between OpenAI and Microsoft, alongside OpenAI’s transition to a Public Benefit Corporation (PBC), represents a transformative moment for both organizations and the broader tech industry. By structuring itself as a PBC, OpenAI is signaling a long-term commitment to aligning advanced AI development with public interest, ensuring that social benefit remains a legal and strategic priority alongside profit.
The reported $100 billion equity stake for the OpenAI nonprofit positions it as one of the most well-resourced philanthropic entities globally, enabling it to fund large-scale community initiatives like the newly launched $50 million grant program. This move not only enhances OpenAI’s financial capacity but also reinforces its mission to democratize and responsibly guide AI.
For Microsoft, the non-binding MOU marks a continuation—and deepening—of a powerful strategic alliance. As a major investor and infrastructure partner, Microsoft stands to benefit significantly from OpenAI’s innovation pipeline, while also aligning itself with a model of ethical AI leadership.
