The debut is done. After 24 years as a private company, SpaceX (NASDAQ: SPCX) is now a public stock, and a volatile one. Shares priced at $135, opened at $150, traded as high as about $177, and closed at about $161 as of this writing — a gain of about 19% on the day, with the stock continuing to climb in after-hours trading.
That move values the rocket and satellite company at roughly $2.1 trillion, up from the $1.77 trillion the IPO price implied. It makes SpaceX one of the most valuable companies in the U.S. on day one, ahead of names like Meta Platforms and founder Elon Musk’s own Tesla.

So the interesting question is no longer whether the IPO would succeed. It clearly did. The question for anyone watching the ticker now is whether buying after a 19% pop is a disciplined move or a foolish chase.
Here’s a closer look at both sides.
The bull case
Start with Starlink, the satellite internet business that does most of the heavy lifting. SpaceX’s initial public offering (IPO) disclosures show the connectivity segment, primarily driven by Starlink, generated about $11.4 billion in revenue in 2025, about 61% of the company’s total, and it is the only segment producing consistent profits — roughly $4.4 billion in operating income, or an operating margin of about 39%.
And the subscriber growth has been steep. Starlink ended 2023 with about 2.3 million subscribers, a figure that climbed to about 8.9 million by the end of 2025 and surpassed 10 million by the first quarter of 2026. The company also has pricing levers it has barely started to pull. After letting average revenue per subscriber fall about 18% to roughly $81 a month between 2023 and 2025 to win volume, SpaceX raised some Starlink prices by up to $10 a month in May.
Then there’s the launch business, where SpaceX is dominant in a way few companies are dominant in anything. The company said its rockets accounted for more than four-fifths of all mass launched into orbit in 2025. That is the kind of position that is extraordinarily hard for a competitor to replicate, and it underpins the scarcity argument that helped drive demand for the shares.
There is also the simple fact that there is no other public stock quite like this one. Investors who want exposure to commercial space, satellite broadband, and Musk’s broader ambitions now have a single way to get it. That uniqueness arguably commands a premium on its own.
