Elon Musk has officially crossed the $600 billion, making him the first person in history to reach this level of wealth.
This comes after SpaceX, his private aerospace company, launched a December tender offer valuing the firm at $800 billion, double its worth in August, according to two investors who spoke to Forbes.
Musk, who owns roughly 42% of SpaceX, sees his stake alone jump by an estimated $168 billion, bringing his total net worth to around $677 billion as of Monday noon Eastern Time.
SpaceX is preparing for a public offering in 2026, which could value the company near $1.5 trillion. Even without the IPO, Musk’s SpaceX holdings are now his single most valuable asset.
Tesla is a major contributor too; his 12% stake in the electric vehicle company is estimated at $197 billion. Meanwhile, Musk is appealing a Delaware court decision that voided parts of his 2018 CEO Performance Award, which Forbes has discounted by 50% pending the outcome, currently estimated at $69 billion.
Musk’s reach extends beyond Tesla and SpaceX. His AI startup, xAI Holdings, is reportedly in talks to raise $15 billion in new funding at a $230 billion valuation, double its March 2025 valuation of $113 billion. Musk owns 53% of xAI, which Forbes estimates at $60 billion.
Tesla shareholders have also approved a record-breaking $1 trillion pay plan for Musk, contingent on achievements such as growing Tesla’s market capitalisation eightfold over the next decade. “Mars shot” targets like this show Musk’s vision of merging electric vehicles with robotics and AI.
Over the past five years, Elon Musk has repeatedly rewritten the record books, making the $600 billion worth no surprise.
He was worth $24.6 billion in March 2020, surpassed $100 billion in August 2020, $200 billion in 2021, $300 billion later that year, $400 billion in December 2024, and $500 billion in October 2025. His lead over the second-richest person, Google co-founder Larry Page, now sits at $425 billion.
SpaceX’s growth, particularly through Starlink’s expansion to over three million subscribers and ventures into aviation and maritime internet services, is a key driver of Musk’s wealth surge.
Tesla, despite slower sales, has seen its stock climb 13% this year, partly due to investor confidence in Musk’s robotics and autonomous vehicle ambitions.
If the SpaceX IPO meets its projected valuation, Musk could soon become the first trillionaire in history.
