Elon Musk has reclaimed the number one position on Forbes's 2025 World's Billionaires list, boasting a net worth of $342 billion as of March 7th. This makes him the richest person Forbes has ever tracked, surpassing Mark Zuckerberg by $118 billion. Musk's wealth has grown by 75% since last year, largely due to the increased valuation of his companies. SpaceX, now his most valuable asset, is valued at $350 billion, nearly double its previous year's valuation. Musk owns 42% of SpaceX and 13% of Tesla, which has also seen a 50% increase in value since last year. Additionally, Musk's artificial intelligence business, XAI, raised $6 billion at a $50 billion valuation, doubling its value in six months. Musk's strategic financial moves, including the acquisition of the social media company X, have further increased his wealth and influence. Musk's political involvement has also grown alongside his wealth. He was a major donor to Donald Trump's campaign, spending nearly $300 million during the 2024 election cycle. His influence extends to government contracts, with SpaceX's Starlink reportedly securing a $2.4 billion contract with the Federal Aviation Administration. Despite public outcry, Musk continues to use his wealth to influence political outcomes, as seen in his recent involvement in Wisconsin's Supreme Court race. Musk's financial and political maneuvers have solidified his position as a powerful figure in both business and politics.
