His Tesla has a market valuation of $1.4 trillion as of Wednesday.Forbes ValuationMusk is the wealthiest person in the world with an estimated net worth of $824.3 billion as of Wednesday. He became the first person to be worth $400 billion in 2024, and his fortune crossed the $500 billion, $600 billion, $700 billion, and $800 billion thresholds in 2025 and 2026, respectively. Musk holds an estimated 43% stake in SpaceX, which would all but guarantee his net worth rising above $1 trillion. Even before SpaceX’s IPO, Tesla shareholders approved a compensation package for Musk in November that could be worth close to $1 trillion, but requires the automaker to achieve several goals over the next decade.Key BackgroundSpaceX’s much-anticipated filing will provide insight into the company’s operations and finances, after spending years developing products for NASA and other agencies. Musk was reportedly hesitant to take SpaceX public in 2013, telling employees at the time that Tesla went public because he “didn’t have any choice,” though he now likely seeks additional funding to bolster his xAI among competitors OpenAI and Anthropic. Musk has also sought to develop the first data centers in space, a concept OpenAI’s Sam Altman explored by possibly partnering with or acquiring a rocket company, the Journal reported. What To Watch ForPossible IPO filings from OpenAI and Anthropic. On Tuesday, OpenAI announced it raised $122 billion in its latest funding round, bringing its post-money valuation to $852 billion with backing from Amazon, Nvidia, Microsoft and SoftBank. Anthropic is considering going public as soon as October in a listing that could raise more than $60 billion, according to The Information.Further ReadingSpaceX Has Filed Confidentially For IPO Ahead Of AI Rivals (Bloomberg)Musk’s SpaceX Files To Go Public In One Of The Biggest IPOs Ever (Wall Street Journal)
