Elon Musk’s personal fortune has blasted past a new frontier, briefly touching $500 billion this week. This monumental figure, which later stabilized at $499 billion, isn’t just a story about electric cars; it’s a reflection of a diversified and futuristic business empire that spans from Earth’s roads to outer space and artificial intelligence.
While his 12% stake in the $1.5 trillion-plus behemoth Tesla is the cornerstone of his wealth, his other ventures are becoming incredibly valuable in their own right. His rocket company, SpaceX, is a critical player in aerospace and is reportedly seeking a valuation of $400 billion. Musk’s 42% stake in SpaceX represents a massive portion of his non-Tesla wealth and highlights his dominance in the private space industry.
Adding to this futuristic portfolio is his burgeoning artificial intelligence company, xAI. Despite being a newer player, xAI has already garnered a valuation of $75 billion as of July, according to Pitchbook data. This rapid growth underscores investors’ belief in Musk’s ability to innovate and lead in what many consider the next great technological revolution.
Of course, Tesla remains the star of the show. Its recent stock performance, up 13% for the year, has been phenomenal. The company’s recent success was highlighted by its third-quarter delivery report, which saw 497,099 vehicles handed over to customers, a figure that easily surpassed analyst predictions and was aided by a strategic rush for a US tax credit.
Musk’s journey in 2025 has been a rollercoaster, from facing criticism over his distractions to reaffirming his commitment with a $1 billion stock purchase. His current net worth, whether measured by Forbes ($499B) or Bloomberg ($470B), places him far ahead of any rival, cementing his legacy not just as a carmaker, but as a multi-industry titan.
