OpenAI proposes converting its for-profit arm into a Public Benefit Corporation

OpenAI published a blog post laying out plans to convert its capped-profit operating company into a Delaware public benefit corporation, the first detailed public statement of a restructuring that would take nearly two years to complete. The company said the change was needed to raise capital “with conventional terms like others in this space,” arguing that its existing structure — a for-profit LLC controlled by, and with returns capped for the benefit of, a non-profit parent — had become an obstacle to the scale of investment frontier AI development required.

Under the proposal, the non-profit would give up direct operational control of the renamed for-profit entity but would retain what OpenAI described as a “significant interest” in it, one to be set by independent financial advisors, which OpenAI said would leave the non-profit among the best-resourced philanthropies in the world. The post did not specify a percentage stake or valuation, leaving the terms that would ultimately matter most — how much equity and control the non-profit kept — to later negotiation.

The announcement drew immediate opposition. Elon Musk, who had already sued OpenAI over its earlier 2019 shift to a capped-profit model, expanded his legal challenge to argue the new plan would complete a betrayal of the organisation’s founding non-profit mission for private gain. Meta wrote to the California attorney general opposing the change on similar grounds, arguing OpenAI should not be permitted to convert charitable assets into a vehicle for ordinary commercial return. Microsoft, OpenAI’s largest investor and commercial partner, said publicly that it wanted a stable long-term partnership but that terms covering equity, exclusivity and intellectual property rights remained under negotiation.

The December 2024 announcement set the terms of a fight that ran through most of 2025, drawing in the California and Delaware attorneys general as regulators with approval power over the change. OpenAI completed the restructuring in October 2025, with the non-profit — renamed the OpenAI Foundation — retaining formal control and a stake reported at roughly 26%, a resolution closer to what critics had pushed for than what OpenAI’s initial framing here had implied.
