U.S. regulators and Elon Musk are negotiating a settlement to resolve litigation over his 2022 Twitter share disclosures. A joint court filing confirms both sides are seeking a resolution by April 1.

The SEC accuses Musk of illegally delaying a 5 percent stake announcement to purchase hundreds of millions of dollars in shares cheaply. He faces allegations of saving $150 million.

This legal battle mirrors a 2018 dispute settled for $20 million. Meanwhile, Musk retains a fortune estimated at $834 billion as SpaceX prepares for a potential IPO.
