Elon Musk, CEO of Tesla and SpaceX, faces potential federal contract cancellations after a public feud with former President Donald Trump.
Musk has invested heavily in Trump and Republican campaigns, contributing at least $288 million, which initially seemed to secure government support. However, tensions escalated, with Trump threatening to withdraw federal contracts from Musk's companies.
"While Trump and the GOP have benefited from Musk’s money, Musk is most vulnerable if the president uses the levers of government to retaliate — a prospect the president raised in a message last week threatening to cancel Musk’s companies’ federal contracts."This conflict has had significant financial repercussions. Bloomberg reports Musk’s personal net worth dropped by $34 billion, marking the second-largest loss in Bloomberg Billionaires Index history. Tesla’s stock also plunged over 20% year-to-date, with a sharp decline coinciding with the feud’s peak.
"Tesla’s shares are down more than 20 percent year-to-date, falling precipitously Thursday as the verbal warfare between Trump and Musk escalated before slightly rebounding Friday."Government support for Musk’s ventures has been substantial, with a Washington Post analysis revealing at least $38 billion in contracts, loans, subsidies, and tax credits awarded over the years.
"A Washington Post analysis this year found that the billionaire and his businesses have received at least $38 billion in government contracts, loans, subsidies and tax credits over the years."The unfolding dispute highlights the risks billionaires face when political alliances sour, especially when their business interests rely heavily on federal backing.
