How to navigate the hottest IPO in history: SpaceX
SpaceX prices tonight at $135 a share, valuing the company near $1.75 trillion the largest IPO ever. Here’s the data behind the hype, and a framework for thinking clearly about it.
Tomorrow, SpaceX begins trading on the Nasdaq under the ticker SPCX. Pricing was set at a fixed $135 per share for roughly 555.6 million shares about a $75 billion raise at a $1.75 trillion valuation. If that holds, it’s the largest IPO in stock market history, putting SpaceX above Tesla as roughly the seventh largest company in the United States.
For founders, operators, and investors who’ve spent the last decade watching SpaceX from the outside, this is a genuinely unusual moment. A company most of us have only been able to access through secondaries is now a click away on Robinhood, Fidelity, or Schwab. This post isn’t about whether to buy it’s the data and the framework I’d want in front of me before forming a view.
Why this IPO is different
A few structural details stand out, and they matter for how you think about day one.
The retail float is unusually generous. SpaceX reportedly wants retail investors to take roughly 30% of the offering about $22.5 billion. For comparison, Fidelity notes the typical retail slice of an IPO runs 5–10%. SpaceX named Schwab, Fidelity, Robinhood, SoFi, and Morgan Stanley’s E-Trade as platforms making shares available, and held a dedicated event for around 1,500 retail investors as of today June 11.
The valuation is doing a lot of work on narrative, not just fundamentals. At $1.75 trillion, the price isn’t just reflecting today’s Starlink subscriber revenue it’s pricing in Starship reaching full reusability, and the xAI/Grok/Colossus compute stack folded into SpaceX in February 2026. That’s a legitimate thesis, but it’s a thesis. The first real fundamentals check comes with the first quarterly report as a public company, expected around September.
Insider concentration is significant. Elon Musk’s ownership and voting control remain substantial. Valor Equity Partners’ Antonio Gracias, a SpaceX board member, held about 7.3% of Class A shares pre-IPO. President and COO Gwynne Shotwell holds Class B shares carrying 10x the voting power of Class A stock. That’s normal for a founder led tech company at IPO, but it’s worth understanding when thinking about how much influence public shareholders will actually have.
What the S-1 actually shows
SpaceX’s prospectus gave the first real look at its numbers and the picture is more complex than “rockets and Mars.”
Starlink is the engine. It generated $11.4 billion in 2025 revenue (up ~50% year over year) and $4.4 billion in operating profit at roughly a 63% adjusted EBITDA margin the company’s only profitable segment. The Space segment (launch, NASA, Pentagon contracts) brought in $4.1 billion but operated at a loss as Starship development absorbed about $3 billion in R&D. The newly folded-in AI segment, xAI, generated $3.2 billion in revenue and a $6.35 billion operating loss for the year.
The flip side: average revenue per subscriber has been falling as SpaceX trades ARPU for global volume from $99/month in 2023 to $81 in 2025, and $66 in Q1 2026. In May 2026, SpaceX raised Starlink plan prices by up to $10/month, signaling a shift toward monetizing its installed base after years of landvgrab growth.
On a consolidated basis, SpaceX posted a $4.9 billion net loss and a $2.6 billion operating loss for 2025, with adjusted EBITDA of $6.6 billion and total longvterm debt of $29.1 billion as of March 2026. The company’s own TAM estimate is striking: $28.5 trillion, split roughly into $370 billion in space, $1.6 trillion in connectivity, and $26.5 trillion in AI. Whether that AI TAM materializes for SpaceX specifically is, to put it mildly, unproven.
How I’d think about this if I were you
I’m not going to tell you whether SPCX is a buy. I’m not a financial advisor, and anyone offering a confident price target for day one of a $1.75 trillion IPO is selling certainty that doesn’t exist. What I can offer is the framework I use for any highvconviction, highvhype deal, public or private.
Separate the company from the stock
SpaceX is one of the most important companies of this generation in launch, satellite internet, and increasingly compute. None of that is in question. But “great company” and “good entry price” are different judgments. Conflating them is one of the most common mistakes I see when a brand name company goes public.
Expect mechanics, not fundamentals, on day one
With a relatively constrained float against enormous global demand, early price action is likely driven by supply demand technicals and potentially index fund flows if SPCX qualifies for major benchmark inclusion shortly after listing. That’s how mega cap IPOs with limited float tend to trade in the first weeks.
Watch the right signal
The signal isn’t the day one pop or drop it’s what SpaceX says about Starlink unit economics, AI infrastructure margins, and capital allocation once lock-ups lift and the first earnings calls happen. That’s where you’ll learn whether the $1.75T thesis holds up.
Be honest about why you’re buying
For many retail investors, this may be the first chance to own a piece of a company like SpaceX at all. If that’s the appeal, be honest about whether you’re investing or buying a piece of a story you want to be part of. Both are valid but they call for very different position sizes.
A note on perspective
Some commentators have framed this IPO as a wealth transfer from retail investors to insiders, and there’s a version of that critique worth taking seriously: insiders and early stage investors are realizing liquidity at a valuation that, by definition, prices in years of future execution. That’s true of essentially every high-profile tech IPO it’s not unique to SpaceX. The question isn’t whether early investors are “winning” they almost always do, because they took the early risk. It’s whether the price you’re being offered today still leaves room for you to win too.
The bottom line
This is a landmark moment for public markets, and it’s reasonable to want exposure to a company doing what SpaceX is doing. But treat it like any high conviction opportunity that’s also extraordinarily hyped: understand the deal structure, separate the long term story from the short term mechanics, size your position accordingly, and wait for real data not headlines before forming a strong view on valuation.
