Elon Musk, one of the most wealthy people on the planet, wants to buy Twitter for $43 billion in cash. The $16.4 billion he netted from sales of Tesla shares last year may turn out helpful.

CFRA Research analyst Angelo Zino said “Musk could look to fund the transaction, if approved, through a combination of debt financing and potentially Tesla shares,”

“Given the size of the transaction, we think it is conceivable that some Tesla shares could be sold given much of his wealth is tied to the company.” The analyst added.

Elon Musk made a string of transactions as he offloaded about 10% of his stake in the electric car maker to meet tax withholding obligations related to the exercise of stock options.

Wells Fargo analyst Colin Langan warned of the possibility of more share sales to come. “There is a risk if he (Musk) decides to sell more Tesla shares to fund the takeover which could put pressure on the stock.” He said.
