Elon Musk has sold almost $4 billion in Tesla stock in preparation for his acquisition of Twitter.
Much of Musk's money is stored in stocks and other assets, which means that in order to purchase the platform, he must liquidate part of those assets.
The IRS will tax around $1 billion of the proceeds from the transaction, leaving Musk with approximately $3 billion.
According to some analysts, Musk made roughly $3 billion last year by selling Tesla stock, which still leaves him with a large fortune.
He's around $21 billion short of what he'll need to pay Twitter to complete the deal.
Musk has two options: sell a portion of his SpaceX investment or find an equity partner.
