Elon Musk becomes world's first trillionaire

The world’s richest person, Elon Musk, has hit yet another milestone of $600 billion due to soaring valuation of his rocket maker SpaceX.

This makes him the first person to hit the trillionaire status in the world.

Earlier in December 2025, Musk’s rocket maker SpaceX launched a tender offer valuing the firm at $800 billion, up from $400 billion in August, two of the company’s investors told Forbes.

This boosts the fortunes of Elon Musk, who owns an estimated 42% of SpaceX, by $168 billion to an estimated $677 billion on Monday, December 15, 2025.

The tender offer comes as SpaceX is targeting an IPO in 2026 that could value the company at around $1.5 trillion, one of the company’s investors confirmed to Forbes.

The tender offer and SpaceX’s IPO plans were previously reported by a number of outlets.

Tesla says Musk should be paid $1 trillion - will shareholders agree?

Representatives for Musk and SpaceX did not respond to Forbes’ requests for comment.

Even without an IPO at that valuation, which would likely make Musk a trillionaire, Musk’s estimated $336 billion stake in SpaceX is now his most valuable asset.

His 12% stake in Tesla, meanwhile, is worth $197 billion, excluding stock options from his 2018 CEO Performance Award that were voided by a Delaware judge in January 2024.

If Musk loses that appeal, Tesla could still provide him with an alternative route to becoming a trillionaire.

Moving past the $600 billion net worth mark is just the latest in a series of milestones Musk has achieved over the past half decade.
