SpaceX stock is now public, cementing CEO Elon Musk’s status as the first trillionaire in history. But despite being the world’s richest person, he spends most of his time in a modest home near SpaceX headquarters.

The rocket and satellite company raised $75 billion on Thursday in the largest IPO ever after offering more than 555 million shares at $135 a piece, valuing the company at $1.77 trillion.

On Friday, shares jumped 20% to $162, propelling Musk into trillionaire status after accounting for his SpaceX options as well as his Tesla shares.

Meanwhile, his real estate portfolio is more modest. After Musk moved to Texas in 2020 and eventually brought his companies with him, he sold most of his homes in California.

He bought adjacent properties in an upscale area near Austin, Texas, for about $35 million, much to the annoyance of his neighbors. But Musk revealed in 2021 that his primary home is a $50,000 house in Boca Chica, Texas, which he rents from SpaceX, headquartered in the nearby town of Starbase, near Brownsville.
