Elon Musk has become the first person ever to reach a net worth of $800 billion, according to Forbes, following the acquisition of his AI and social media company xAI by SpaceX. The merger boosted his fortune by $84 billion, bringing it to an estimated $852 billion.

Before the deal, Musk held roughly 42% of SpaceX, valued at $336 billion, and 49% of xAI, worth $122 billion. After the acquisition, he owns a 43% stake in the combined company, now valued at $542 billion, making SpaceX his most valuable asset. He also holds a 12% stake in Tesla, valued at $178 billion, plus $124 billion in stock options, excluding a Tesla pay package that could eventually reach $1 trillion if performance targets are met.
Musk has hit four major wealth milestones in just four months, reaching $500 billion in October, $600 billion by mid-December, $700 billion days later, and now $800 billion after the xAI acquisition. His net worth is now $578 billion higher than Google co-founder Larry Page, putting him on track to potentially become the first person ever worth $1 trillion.
With SpaceX expected to launch an IPO later this year, Musk’s companies will face public market scrutiny, making this historic milestone closely watched by investors worldwide.
