Tesla stock opened at $369.09 on Wednesday, sliding almost 3 percent from its Tuesday closing price of $379.57.
Musk later tweeted that existing stockholders could choose whether to hold onto their shares or sell them to the new investors for $420 a share. "This included discussion as to how being private could better serve Tesla's long-term interests, and also addressed the funding for this to occur", the statement said.

The issue of share accumulation by outsiders emerged only recently as reports that Saudi Arabia's public investment fund had built up a stake from 3 to 5 percent after its offers of purchase of new shares in Tesla were spurned by the company.

Tesla is a legendary cash-burner, with roughly $10 billion in debts and $2 billion in reserves, and Musk would probably need in the tens of billions of dollars to buy out shareholders at the right price.
