Elon Musk's new political party, the America Party, led to a sell-off of Tesla shares, causing a nearly 7% drop in stock value.
The stock sell-off resulted in Musk losing $15 billion in net worth, though he still remains the world's richest person according to the Bloomberg Billionaires Index.
Investors disapprove of Musk's political involvement, with some analysts downgrading Tesla's stock rating due to concerns over regulatory headwinds and distractions from Musk's political moves.
Tesla stocks have been performing poorly, down 31% since Trump's inauguration in January, with back-to-back quarterly declines in vehicle deliveries in 2025, marking the company's worst performance since 2022.
