Halfway There: Musk’s $500 Billion Milestone Ignites Trillionaire Watch

The official “trillionaire watch” has begun. Elon Musk blazed a path into uncharted financial territory this week by becoming the first person ever to be worth $500 billion, placing him exactly halfway to the once-unthinkable trillion-dollar mark. His achievement has shifted the conversation from if anyone will become a trillionaire to how soon Musk will claim the title.
This historic milestone was reached as a direct result of the soaring value of Tesla. The electric car company, in which Musk holds a 12% stake, is now valued at over $1.5 trillion. The stock has been on a powerful run, gaining 13% in 2025 and showing remarkable strength after a period of volatility early in the year.
The fundamentals supporting this valuation are robust. Tesla recently announced it delivered a record 497,099 vehicles in its third quarter, a figure that far surpassed all expectations and showcased the brand’s enduring and powerful consumer demand.
Furthermore, Musk’s other major assets provide a solid secondary launchpad toward a trillion-dollar valuation. His 42% stake in SpaceX, which is reportedly seeking a $400 billion valuation, and his burgeoning AI company, xAI, valued at $75 billion, represent hundreds of billions in additional equity that continues to grow.
With a proposed $1 trillion Tesla compensation plan on the table designed to reward him for pushing the company into AI and robotics, the roadmap to a 13-figure net worth is becoming clearer. This week’s record is a monumental achievement on its own, but it is also seen by many as simply the halfway point in a much larger financial journey.
