Elon Musk's net worth has taken a $15.3 billion hit after the Tesla CEO announced he was to form a new political party. The news sent ripples through financial markets and spooked investors concerned about Musk's political ambitions and possible implications for Tesla's brand and business operations.

Ross Gerber, a longtime Tesla investor and vocal Musk critic, didn’t hold back online, writing in his own post that, “no one wants the Elon first party,” accusing the company’s board of being “Elon vampires sucking the blood of Tesla equity.”
