Elon Musk Hits Historic $600 Billion Net Worth Milestone

Elon Musk has moved significantly closer to potentially becoming the world’s first trillionaire.

According to two SpaceX investors speaking with Forbes, the aerospace company recently initiated a tender offer that places its value at $800 billion—double its $400 billion valuation from August.

This increase has added approximately $168 billion to Musk’s wealth, bringing his total estimated net worth to roughly $677 billion as of midday Monday Eastern time. This makes Musk the first individual in history to surpass the $600 billion threshold, with no one previously reaching even $500 billion.

According to a company investor who spoke with Forbes, SpaceX is preparing for a 2026 public offering that could reach a $1.5 trillion valuation. Multiple news organizations had already covered both the tender offer and the IPO plans. Neither Musk nor SpaceX representatives provided comments in response to Forbes’ inquiries.

Based on Forbes’ calculations, Musk’s approximately $336 billion SpaceX stake (representing an estimated 42% ownership) now constitutes his largest asset, even before any IPO at the projected valuation that would likely push him past the trillion-dollar mark.

His Tesla holdings—a 12% stake—are valued at $197 billion, not including the stock options from his 2018 compensation plan that a Delaware judge invalidated in January 2024. Forbes has reduced those options’ estimated value by half to $69 billion while Musk’s appeal proceeds in the Delaware Supreme Court.

Should the appeal fail, Tesla might still offer Musk a path to trillionaire status.

Tesla shareholders granted approval in November for an exceptional compensation package that could award Musk as much as $1 trillion in additional shares (prior to taxes and the expense of accessing the restricted stock) if the company meets ambitious performance targets, including growing its market capitalization over eight times within the coming decade.

Additionally, Musk’s xAI Holdings is allegedly pursuing new investment at a $230 billion valuation—more than twice the $113 billion value Musk stated when establishing the company in March through combining his AI venture xAI with his social platform X (previously known as Twitter).

Forbes places Musk’s xAI Holdings ownership at approximately 53%, worth around $60 billion.

Crossing the $600 billion wealth threshold represents merely the most recent achievement in a string of financial milestones Musk has reached over the last five years.

His fortune totaled $24.6 billion in March 2020, but rising Tesla stock prices elevated him to become the fifth individual ever to reach $100 billion by that August.

He first claimed the position of world’s wealthiest person in January 2021 with nearly $190 billion.

By September 2021, he became only the third person to attain $200 billion (following Amazon’s Jeff Bezos and French luxury goods magnate Bernard Arnault of LVMH).

Musk subsequently reached $300 billion in November 2021, $400 billion in December 2024, and $500 billion in October.

Oracle’s Larry Ellison remains the only other individual to have reached both the $300 billion and $400 billion levels.

Musk now stands closer to achieving trillionaire status than to losing his position as the planet’s wealthiest individual, maintaining a $425 billion advantage over the second-place holder, Google co-creator Larry Page, whose estimated wealth is $252 billion.

Given that Musk is merely $23 billion away from the $700 billion mark, his next major financial milestone may arrive soon.
