Elon Musk’s net worth dropped by over $350 billion after SpaceX shares fell more than 31% from their peak following its IPO debut, erasing nearly $900 billion in market value. His fortune slid from $1.45 trillion to just over $1.1 trillion. The decline was linked to a weak MSCI sustainability rating - one of the world’s largest stock market index provider - and concerns over governance and dilution from recent acquisitions. Despite the setback, Musk remains a trillionaire as SpaceX continues to expand through major deals and debt refinancing. #musk #trillionaire #spacex #usa
