Elon Musk has revealed that Neuralink, his brain-chip implant company, is facing a probe from the Securities and Exchange Commission, with which he has long feuded.
Musk posted a letter on the subject to X Thursday, as well as a mocking, AI-generated image of SEC chair Gary Gensler. He called the SEC "just another weaponized institution doing political dirty work."
"Oh Gary, how could you do this to me?" Musk wrote in the post sharing the letter from his lawyer, Alex Spiro, to Gensler.
In the letter, which was said it was "in the matter of certain purchases, sales, and disclosures of Twitter shares," Spiro said the SEC "reopened" an investigation into Neuralink but didn't elaborate on why. It also said the SEC was preparing action against Musk over his 2022 acquisition of Twitter, now X.
The billionaire later shared another post featuring an AI-generated image of a snail wearing a business suit and said it depicted Gensler.
Neuralink and the SEC didn't immediately respond to requests for comment from Business Insider, made outside normal working hours.
The SEC is investigating how Musk bought shares in Twitter ahead of his $44 billion acquisition of the social network.
Musk started buying shares in Twitter in 2022, and by the spring, he had a 9% stake in the company before he struck a deal to buy it outright later in the year.
Spiro, Musk's lawyer, also said in the letter that the SEC issued a "settlement demand" on Wednesday to agree within 48 hours to make a payment or face enforcement action.
Spiro wrote that this followed "a multi-year investigation and more than six years of harassment" of Musk by the SEC.
This is an apparent reference to the SEC suing Musk in 2018 over a tweet in which he claimed he had the funding to take Tesla private, which led to him being forced to step down as chairman.
