Microsoft has invested $100 billion in its partnership with OpenAI over the years. This substantial investment comes amidst testimony in Elon Musk’s lawsuit, which is scrutinizing OpenAI’s transition to a for-profit model. Despite the ongoing legal challenges, Microsoft continues to be OpenAI’s primary cloud partner, enjoying first access to new models and the right of first refusal under a revised agreement established in late April 2026 that allows OpenAI to host its models on other cloud platforms.

OpenAI: OpenAI operates under a nonprofit foundation that governs its for-profit group, focusing on developing advanced AI models for safe AGI pursuit. It prioritizes rapid innovation in agentic AI and enterprise applications. OpenAI’s longstanding partnership with Microsoft recently evolved to allow greater flexibility in cloud usage and end certain revenue shares, while preserving collaboration on IP through 2032.
Microsoft: Microsoft is a leading technology company providing cloud computing services through Azure, enterprise software, and AI integrations like Copilot for productivity and hybrid work. In 2026, it emphasizes AI diffusion globally and builds dedicated infrastructure for advanced AI workloads. Microsoft has poured extensive resources into its partnership with OpenAI, recently amending terms to shift to non-exclusive licensing while remaining the primary cloud provider and major shareholder.
