The agency, which has been pulling back on lawsuits against major companies, ended a case that had accused Mr. Musk of hiding his purchases of Twitter stock. He agreed to pay $1.5 million.

A trust in the billionaire Tesla CEO's name will pay $1.5 million to settle allegations that Musk failed to properly disclose his purchases of Twitter stock in 2022.

The second week of testimony is underway in Elon Musk's lawsuit against Sam Altman's OpenAI. On Monday, an email sent by Musk two days before the trial came under scrutiny. New York Times tech reporter Mike Isaac joins CBS News with more.

The case had alleged that Musk failed to timely disclose his buildup of ownership in the social-media platform he renamed X.

OpenAI co-founder and President Greg Brockman testified that his stake in the startup is now worth almost $30 billion, prompting an attorney for Elon Musk to ask why he had not donated the bulk of his earnings to the ChatGPT maker’s nonprofit foundation.

OpenAI President Greg Brockman was questioned about his wealth, an email he sent to Yahoo's then-CEO, Marissa Mayer, and the company's IPO plans.

A proposed settlement with U.S. regulators would have Musk pay just $1.5 million. He was accused of cheating investors out of $150 million.

Musk reached out before trial to ask about a settlement and predicted OpenAI leaders would be the “most hated men in America” by week’s end.
