He made a statement that he "may" take Tesla private, "funding is secured". Which was true except there was no signed deal. He was able to put actually 2 different deals on the table within days. One with the Saudis and one with Volkswagen involved. But he did not go through with any of them. Mostly because it was not needed. The big shareholders had reassured him that they are in for the long haul, no matter what the short term share value fluctuations are.
He needs to stay on as CEO and steer Tesla into the future.
I agree that he may need to make one step backwards and be less involved in the details. They have restructured the Tesla leadership to enable to do just that.
The basics are that the SEC made unwarranted noises, offering him a "deal" out of court that would have required him to step down as CEO and put Tesla in turmoil, with share prices tumbling, supporting the Tesla short sellers. Elon kicked their ass, telling them what they can do with that offer. This left them with the choice to go home or open a court case. They filed a court case and immediately made a new offer for off court settlement. This time to step down only as chairman of the board, a much less important post than CEO. He even stays on the board, just not as chairman.
Comments in the media are that this is a most unusual step by the SEC. If they had anything against him they would force him to step down as CEO.
Having said that, I agree that he should not have made the funding remark.
