SEC lawsuit claims Musk gained over $150 million by delaying Twitter stake disclosure

After a more than two-year investigation, the Securities and Exchange Commission has sued Elon Musk over his delayed disclosure of the Twitter stock he amassed before announcing his intention to acquire the company in 2022.

In a court filing, the SEC says that Musk filed paperwork with the SEC disclosing his purchase of Twitter shares 11 days after an SEC-mandated deadline to do so. (Federal law, as the SEC notes in its statement, requires investors to publicly report when they have acquired a more than 5 percent stake in a company.) This delay, according to the regulator, allowed Musk to buy up even more Twitter stock at a time when other investors were unaware of his involvement with the company.

From the lawsuit:

The regulator has been investigating Musk for years, and has long been at odds with the owner of X. At one point, the SEC accused Musk of attempting to stall and use “gamesmanship” to delay its investigation into his investment in Twitter. Last month, Musk shared a copy of a letter addressed to SEC Chair Gary Gensler in which Musk’s lawyer, Alex Spiro, accused the regulator of “six years of harassment” targeting Musk. The letter indicated that Musk refused a settlement offer from the SEC related to its Twitter investigation.

Musk also faced a from other Twitter investors and an related to the delayed disclosure. However, as The New York Times , it’s unclear if the SEC’s latest action will amount to much, as Gensler is expected to step down following the inauguration of President Donald Trump.

X didn’t immediately respond to a request for comment. In a statement to The Times, Spiro called the SEC’s action a “a single-count ticky-tack complaint,” calling it “an admission by the S.E.C. that they cannot bring an actual case.”
