OpenAI on Friday laid out a plan to transition its for-profit arm into a Delaware public benefit corporation (PBC) to help it raise capital and stay ahead in the costly AI race against companies such as Google.

One of OpenAI’s co-founders, billionaire Elon Musk, has filed for an injunction to halt the company’s transition to a for-profit, accusing OpenAI of abandoning its original philanthropic mission. Musk has also alleged that OpenAI has deprived his own AI company, xAI, of capital by extracting promises from investors not to fund it.

OpenAI, the massive artificial intelligence startup valued at about $157 billion, plans to set itself up as a public benefit corporation, or B-Corp., with a focus on social impact.
