Elon Musk’s rocket maker, SpaceX, will debut on the Nasdaq at midday Friday under the ticker “SPCX.” The company sold 555.6 million shares at $135 each, pulling in roughly $75 billion and valuing the firm at about $1.77 trillion. The offering dwarfs every previous IPO, including Alibaba’s 2014 record and captured the attention of investors worldwide today there.

SpaceX’s IPO is the largest ever, but its launch will test demand for mega‑sized debuts from AI leaders like OpenAI and Anthropic later this year. The company’s revenue comes mainly from its satellite‑internet unit, with a fledgling AI arm that could drive future growth beyond rockets for investors seeking high risk returns and new technology.

Nasdaq officials plan to open trading after matching about 10% of the shares—roughly 55 million shares or $7.5 billion—to curb volatility. Yet pre‑IPO investors face a lock‑up that may delay selling, meaning the first day could see limited liquidity and a narrow trading window for initial investors.

The debut will set a benchmark for future mega‑IPOs and signal how much capital the market is willing to pour into high‑growth tech. Investors will watch prices closely, as early performance can influence subsequent valuations for companies like OpenAI and Anthropic in the tech sector today and for future investments today again later this year.
