The once-friendly relationship between Trump and Elon Musk has erupted into a high-stakes feud, with billionaires, lawmakers, and investors closely watching the fallout, according to CNBC. Billionaire Bill Ackman urged Trump and Musk to end their feud, calling for peace “for the benefit of our country” in a post on X. Steve Bannon called on the president to seize SpaceX under the Defense Production Act, revoke Elon Musk’s security clearance, and suspend federal contracts pending an investigation. Billionaire Mark Cuban appeared to support Elon Musk’s proposal to form a new political party representing the moderate majority. Wall Street sold off Tesla shares, causing a 14% drop and erasing $152 billion in market value. Dan Ives of Wedbush called the feud a shock to the market. Wedbush remains bullish on the stock, though Ives acknowledged it complicates expectations under a Trump administration.
