SpaceX opened trading as the sixth-most valuable U.S. public company valued at $2.1 trillion, up from $1.77 trillion in its IPO pricing. The stock jumped 19% on Friday, marking one of the smoothest large offerings ever. The debut made Elon Musk the world's first trillionaire and returned billions to early investors and employees.

Individual investors flocked to SpaceX shares, buying into Musk's vision of placing AI data centers in space. Wall Street had questioned whether markets could absorb a $75 billion offering for an unprofitable venture betting on future AI revenue rather than current space or internet operations. Despite the skepticism, demand remained strong throughout the process.

The IPO distributed substantial gains to stakeholders, surpassing the valuations of Broadcom and Tesla. Investors appear willing to back high-risk plays on AI infrastructure even without current profitability. The offering demonstrated appetite for transformative technology bets over traditional revenue models.
