The two US antitrust agencies sided with part of Elon Musk’s argument to block artificial intelligence startup OpenAI from restructuring as a for-profit company.

U.S. antitrust enforcers weighed in on Friday on Elon Musk's lawsuit seeking to block OpenAI's conversion to a public company, pointing out legal doctrines that support his claim that OpenAI and Microsoft engaged in anticompetitive practices.

OpenAI launched a for-profit subsidiary a year later in order to raise outside capital, including more than $13 billion so far from its biggest backer, Microsoft. However, the non-profit entity, along with employees and investors, currently owns that for-profit subsidiary.

Sam Altman, the CEO of leading AI company OpenAI, denied claims made by his sister Annie Altman that he sexually assaulted her multiple times. Annie filed a lawsuit in a Missouri court on Monday. Annie Altman says that Sam sexually assaulted her between 1997 and 2006.

The OpenAI CEO recently published a blog post reflecting on AI progress, as well as his brief ouster from the company.

The 39-year-old tech mogul denied any wrongdoing in a joint statement alongside his mother, Connie, and two brothers, Max and Jack.
