Elon Musk’s net worth has dropped by $40 billion since his Twitter bid. He stands to lose more even if the deal doesn’t go through

• Elon Musk is already feeling the pain from his acquisition of Twitter due to Tesla’s stock slump.
• If he backs out, he has to pay $1 billion to Twitter, and the company could sue for billions more.
• Here’s what could happen to Musk’s billions whether he goes through with the deal or not.

Elon Musk’s $44 billion acquisition of Twitter has yet to go through, but the world’s richest person is already feeling the hurt.

Musk’s net worth has dropped from $251 billion to $210 billion, or 16.3%, since his offer became public on April 14, according to the Bloomberg Billionaires Index. This is due to Tesla stock slumping 29% since the CEO launched his Twitter bid as most of his fortune consists of the electric carmaker’s shares.

Musk appears to be getting cold feet, tweeting that the acquisition is “on hold” unless Twitter can prove fewer than 5% of its users are bots and reportedly saying at a conference that repricing the deal is “not out of the question.”
