Elon Musk Becomes World's First Trillionaire After $135-a-Share SpaceX IPO

Elon Musk became the world's first trillionaire following SpaceX's public debut on June 12, 2026, at $150 per share, valuing the company at nearly $2 trillion. His net worth is comprised of approximately 38% of SpaceX ($765 billion) and 15% of Tesla ($276 billion).

Elon Musk became the world's first trillionaire on June 12, 2026, after SpaceX's record-setting public debut, which priced at $135 per share and valued the rocket maker at roughly $1.77 trillion before shares jumped past a $2 trillion market capitalization in early trading. The milestone is driven largely by Musk's roughly 38% stake in SpaceX, worth an estimated $765 billion, layered on top of his approximately 15% holding in TSLA, valued near $276 billion.

Musk retained more than 82% of SpaceX's voting power through the structure of the offering, preserving control even as outside investors poured in. The trillionaire threshold, long treated as a theoretical marker of extreme wealth concentration, underscores how thoroughly the AI and space booms have rewarded founders holding concentrated equity in fast-scaling private companies.

The figure remains highly sensitive to SpaceX's freshly minted public valuation, which could prove volatile once lock-ups lapse and the company reports its first results as a listed entity. A pullback in either SpaceX or TSLA shares would quickly compress the headline number, and investors will watch whether the premium multiple assigned to SpaceX's Starlink and launch franchises can be sustained.
