Microsoft and OpenAI just restructured their landmark partnership with a massive $135 billion valuation for OpenAI as a public benefit corporation. The new agreement extends Microsoft's exclusive IP rights through 2032 while allowing both companies more independence in pursuing artificial general intelligence (AGI), marking one of the biggest strategic shifts in the AI industry since their original 2019 partnership began.
Microsoft and OpenAI just rewrote the playbook for AI partnerships. The companies announced a sweeping restructuring of their six-year alliance that transforms OpenAI into a public benefit corporation valued at $135 billion, while fundamentally changing how they'll compete and collaborate in the race toward artificial general intelligence.
The deal preserves Microsoft's position as OpenAI's primary partner but with notable shifts. Microsoft now holds a 27% stake in the restructured OpenAI Group PBC, down from the 32.5% it held before recent funding rounds diluted its position. That $135 billion valuation makes this one of the largest corporate restructurings in tech history, according to the official Microsoft blog announcement.
But the real story isn't the valuation - it's what both companies can now do independently. For the first time since 2019, Microsoft can pursue AGI development alone or with other partners. OpenAI gains similar freedom, able to jointly develop products with third parties and serve them on any cloud provider for non-API products. It's a dramatic shift from their previous exclusive arrangement.
The agreement introduces an entirely new governance structure around AGI declarations. When OpenAI believes it's achieved artificial general intelligence, an independent expert panel must verify that claim. Until that happens, Microsoft retains exclusive rights to OpenAI's frontier models and Azure API exclusivity. But once AGI is verified, the landscape changes completely.
"Microsoft's IP rights for both models and products are extended through 2032 and now include models post-AGI, with appropriate safety guardrails," according to the announcement. That's a significant win for Microsoft, ensuring access to OpenAI's most advanced capabilities even after the AGI milestone.
The financial implications are massive. OpenAI has contracted to purchase an incremental $250 billion in Azure services, though Microsoft loses its right of first refusal as OpenAI's compute provider. That $250 billion commitment dwarfs most cloud deals and essentially guarantees Microsoft a massive revenue stream regardless of how the partnership evolves.
