The SEC is suing Elon Musk for misleading Tesla investors with a tweet

The U.S. Securities and Exchange Commission is suing Tesla CEO Elon Musk for misleading Tesla investors — a lawsuit that escalates the never-ending drama that has surrounded Musk in 2018, a year full of Tesla production holdups, unsubstantiated attacks and now serious legal trouble.

The lawsuit focuses on a tweet Musk sent in August about wanting to take Tesla private at $420 a share. He did not file any kind of formal SEC documents alongside the tweet, but his claim still sent Tesla’s stock soaring, and the stock halted trading shortly thereafter.

The SEC now says that Musk violated multiple SEC rules and called the tweeted statement, in which Musk claimed he had “funding secured” to take Tesla private, “false and misleading.”

The lawsuit seeks to block Musk from serving as an officer or board member for any public company.

“In truth and in fact, Musk had not even discussed, much less confirmed, key deal terms, including price, with any potential funding source,” the SEC’s lawsuit reads.

The lawsuit throws into doubt Musk’s tenure as the CEO of the $50 billion company that has made him into a hero entrepreneur. The SEC is attempting to forbid Musk, who is also the CEO of the private company SpaceX, from serving on any public company’s board.

Tesla shares fell sharply Thursday by more than 10 percent in after-hours trading, to around $273.

Musk was defiant in a statement.

“This unjustified action by the SEC leaves me deeply saddened and disappointed,” he said. I have always taken action in the best interests of truth, transparency and investors. Integrity is the most important value in my life and the facts will show I never compromised this in any way.”

Musk later claimed that he believed he had a confirmed a funding source from the Saudi Arabian government. (He reportedly sent the tweet while driving to the airport.) Long frustrated by short-sellers who make money on Tesla’s stumbles, Musk ultimately decided that the ambitious take-private plan was not feasible.

Musk has become a larger-than-life, mainstream celebrity of sorts over the past few years, starting companies seemingly on a whim, including “The Boring Company” that digs tunnels and sold flamethrowers to fans.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
