SpaceX made its long-awaited stock market debut on Friday, closing up 19% above its initial IPO price of $135, according to TechCrunch — and in doing so, minted the world's first trillionaire in Elon Musk.

The milestone arrives wrapped in controversy. The Verge noted that while the IPO stands to make Musk "the richest person to ever walk the planet," his record includes serious personal conduct issues, with the outlet pointing specifically to an incident last year in which Musk's actions "directly led" to harmful consequences.

The offering was not without hiccups. According to Engadget, some Robinhood users looking to buy shares encountered technical problems as the platform buckled under demand. Gizmodo noted the listing arrived with notable "stowaways" — most prominently xAI, Musk's artificial intelligence company, which was folded into SpaceX ahead of the offering.

That pre-IPO restructuring is drawing scrutiny on Capitol Hill. According to CNBC, the husband of Republican Rep. Lisa McClain purchased up to $250,000 in xAI before it was absorbed into SpaceX, raising ethics questions about whether members of Congress or their families are positioned to profit from companies subject to federal oversight.

Meanwhile, SpaceX president Gwynne Shotwell dropped fresh hints at a potential SpaceX-Tesla merger. TechCrunch described such a combination as appearing "inevitable," which would unite two of Musk's flagship companies into a single, historically dominant corporation.

The deeper story is one of concentration: a single individual now commands a private space program, an AI company, a social media platform, and an electric vehicle giant — and just became the wealthiest human ever to live.
