OpenAI Finalizes Shift to Public-Benefit Company as Microsoft Takes 27% Stake

The $500 billion recapitalization leaves control with the OpenAI Foundation.

Overview

  • Microsoft secures roughly a 27% holding and access to OpenAI models through at least 2032, as OpenAI commits about $250 billion in Azure compute and gains flexibility to use other cloud providers.
  • OpenAI says the foundation retains oversight with an approximately 26% stake, and attorneys general in Delaware and California declined to oppose the restructuring after negotiations on governance and safety commitments.
  • Bloomberg reports Microsoft may continue to receive about 20% of OpenAI revenues under the new arrangements until an independent panel verifies the arrival of artificial general intelligence.
  • In a letter to the White House OSTP, OpenAI urges a national effort to add 100 gigawatts of new U.S. power capacity annually and proposes incentives for semiconductors, data centers, critical materials and transmission buildout.
  • OpenAI discloses that about 0.15% of ChatGPT’s 800 million weekly active users show clear suicidal ideation and says GPT-5 meets enhanced mental-health safety protocols in 91% of tests after work with more than 170 experts, as global forums press for binding AI rules.
