He said that the news comes on Thursday at 14.00 ET.
It is not clear whether Musk will announce something newsworthy. Musk made a few changes to his Twitter bio, which could be clues to the announcement: He changed his Twitter name to "Elon Tusk" and added an elephant emoji. He also changed his image to a picture of Mars with the word "Revive" on it.
At one point, Tesla's site began to lead users away from models X, Model S, and Model 3 to a landing page that referred to the upcoming announcement, saying, "Good stuff is launched."
Some suggest that Tesla news may involve the company's upcoming model Y SUV, updates to its autonomous driving software or news about its network of Tesla Supercharger drives.
It is not clear whether Tesla has considered Musk's latest tweets about the announcement. A spokesman did not immediately respond to a request for comment on Thursday.
Regulators on Monday had asked a federal judge to hold Musk contempt to break a deal reached last year involving criticism of Musk's Twitter use. Musk and Tesla settled their dispute with the SEC in October. They agreed to pay $ 40 million in fines and to begin policing Musk's social media post after he caused a stockpile of tweets that regulators said overhyped Tesla's value.
But Musk pulled regulators ire again with a February 1[ads1]9 tweet that exaggerated how many cars Tesla plans to deliver in 2019. The SEC claims that Musk did not receive pre-approval for that tweet.
If the judge is sitting with the SEC, it can postpone Musk for serious new consequences.
