The biggest stock market debut in history is two days old, and the woman who has run SpaceX’s operations for more than two decades wants you to know where to look.
SpaceX (SPCX) closed its first session at $160.95 on June 12, a 19% jump from its $135 offer price, according to CNBC. That pushed its market value past $2.1 trillion overnight.
The raise was staggering: roughly $75 billion, nearly triple Saudi Aramco’s 2019 record, NPR reported.
Now comes the harder part for everyday buyers: figuring out whether the stock holds.
What SpaceX president Gwynne Shotwell told SPCX investors to track
Gwynne Shotwell did not dodge the valuation question when CNBC’s Morgan Brennan asked her, on IPO day, what investors should actually measure.
She named three things: Starship, Starlink, and AI.
Folks should be watching how we’re doing on Starship.
“Folks should watch consumer growth — consumer and enterprise growth on Starlink and Starlink mobile. And then, of course, we’ve got the Grok, we’ve got AI, we’ve got coding. There’s a lot. There’s actually a lot going on,” Shotwell told CNBC.
Her list is a useful filter because SPCX is really three companies under one ticker: a rocket business, a satellite internet business, and an AI division built around xAI.
Each sits at a different stage and moves the stock for different reasons.

Why Starlink is a critical watch for investors
Start with the segment already making money.
Starlink brought in $11.39 billion in revenue last year and posted $4.4 billion in operating income, according to the S-1 filing.
It serves 10.3 million subscribers across more than 160 countries, with its user base roughly doubling in 12 months.
Shotwell flagged a detail that matters more than the subscriber count. SpaceX is short on capacity in some of its best markets.

“We are actually constrained by capacity in many markets, really important markets, so scaling is actually really quite important to the revenue story for us,” she told CNBC.
In plain terms, demand is outrunning supply.
That caps near-term revenue until the next satellites reach orbit, which is exactly why Shotwell put the rocket first. Watch subscriber adds, revenue per user, and whether new capacity arrives on time.
How Starship and orbital AI tie SpaceX’s three bets together
Starship is the engine behind almost everything SpaceX wants to do next.
The fully reusable rocket has cost about $15 billion so far, Shotwell told CNBC. The company is targeting commercial launches in the second half of 2026, and that timeline is the one to circle.
Starship delivers the high-capacity V3 Starlink satellites and underpins SpaceX’s most speculative idea: data centers in orbit.

Musk unveiled an AI1 data satellite this week, with orbital compute testing possible as soon as next year, Brennan noted during her CNBC interview.
Independent experts doubt those arrive soon, Northeastern Global News reported.
That skepticism matters to the price of SpaceX stock.
The company raised money in March at an implied $450 billion value for the launch and Starlink units alone.
The $1.75 trillion IPO mark means investors are paying roughly $1.3 trillion for ideas that have not yet generated commercial revenue.
What the Grok and xAI unit still has to prove
The AI leg draws the most heat from skeptics.
SpaceX absorbed xAI in February 2026, bringing in the Grok models, X, and an image generator. The unit made $3.2 billion in revenue last year but incurred a $6.4 billion loss.
Those losses pulled the company to a $4.9 billion net loss for the year and a $4.28 billion net loss in the first quarter of 2026, according to its SEC filing.
Goldman Sachs, the lead underwriter, projects the AI unit will grow revenue roughly 100 times by 2030.
Morningstar is far less convinced, with a fair value near $780 billion. When Shotwell pointed to Grok and AI, she pointed at the part of the story with the highest ceiling and the least proof.
Three things to track before the first earnings report
- Starlink scaling: Subscriber growth and whether V3 capacity relieves constrained markets, based on SpaceX’s IPO disclosures.
- Starship cadence: Whether commercial launches hit the second-half 2026 window.
- xAI economics: Whether Grok revenue scales toward profit instead of wider losses, as Morningstar flagged.
What new SPCX investors should weigh before buying the pop
A first-day surge is exciting, but it is not enough reason to buy into a stock.
Shotwell signaled patience, telling CNBC the company wants long-term investors and that “not everything has to get done the first day,” according to Benzinga.
There is also a control issue, since Musk keeps more than 82% of voting power through super-voting shares, even after the raise.
The first public earnings report, expected in November 2026, will be the real test.
Until then, Shotwell’s scorecard is the cleanest gauge: Starlink has to keep printing cash, Starship has to fly on time, and Grok has to stop bleeding.
Hit all three and SpaceX’s valuation becomes defensible. Miss them, and doubt starts to creep in.
