What Investors Need to Know Before an IPO

Many investors have been waiting for an opportunity to invest in SpaceX NASDAQ: SPCXElon Musk's space-focused company. The wait is almost over. SpaceX is expected to debut on the Nasdaq exchange on June 12, 2026, under the ticker symbol SPCX.
But first, the company had to deliver the goods to institutional investors who would put a price on SPCX. That was one step closer to reality when SpaceX filed its public S-1 on May 20.
Generational Opportunity or Hype Trap?
Investors have been wondering if SpaceX is a productive investment opportunity in the space economy, or if it is a trap. The initial objection was research data from the World Economic Forum and McKinsey & Company predicting that the space economy will grow from $630 billion in 2023 to $1.8 trillion in 2035.
Arguing this is the following commentary surrounding the company's founder and CEO, Elon Musk. It's not that investors doubt Musk's ability. But there are concerns about how much bandwidth Musk can have while still running Tesla NASDAQ: TSLA and X, among his other efforts.
Musk himself is no stranger to hype. In another part of the S-1 filing, Musk cited SpaceX's market cap (TAM) at $28.5 trillion. That's a staggering number based on $22.7 trillion in business claims.
That number is … ambitious. And it's just the kind of number Musk is using to defend raising up to $75 billion in the $1.75 trillion to $2 trillion range. That would make it the largest initial public offering (IPO) in history.
What Really Drives Business
Before accepting or rejecting Musk's vision for virtual value, however, investors should understand what exactly makes money today. SpaceX operates two separate business lines that tell very different stories.
The first is the launch business (ie, rockets, satellites, and government contracts), which is the company's founding mission and still its most visible product. SpaceX has achieved something no private company has achieved before: a reusable rocket system that dramatically reduced the cost of reaching orbit and gave the company a capability very close to the capacity of heavy-lift launches in the United States. NASA, the Department of Defense, and commercial satellite operators all depend on it.
The second business, and the most important from a revenue perspective, is Starlink—the company's low-Earth satellite Internet service. Starlink is the profit engine that holds business together. It has reached millions of subscribers in over 100 countries, generating recurring subscription revenue that a startup, for all its strategic importance, cannot match on its own.
Without Starlink's cash flow, SpaceX's ambitions for Mars colonization and point-to-point travel would have been more difficult to finance. Investors should think of SpaceX less as a rocket company and more as a direct integrated space infrastructure business where Starlink is funding moonshots.
The Governance Question Investors Can't Ignore
IS-1 confirms what many expected: Elon Musk retains powerful voting control of SpaceX through a two-tier stock structure. This is not unusual in the tech world—Meta Platforms NASDAQ: METAAlphabet Inc. NASDAQ: GOOGLand Snap Inc. NYSE: NOTE everything came out with the same arrangements. However, it carries some risk that SpaceX investors need to price in.
In practical terms, it means that public shareholders will have limited ability to influence the company's direction, compensation decisions, or key strategies. If Musk decides that SpaceX must accelerate its Mars program at the expense of near-term profits, few shareholders can stop him.
This is also linked to bandwidth concerns. When Musk's attention is divided—between Tesla, xAI, X, and whatever comes next—the board has no structural mechanism to intervene. Investors accustomed to the protections of traditional corporate governance should go in with clear eyes on this point.
What to Watch on the 12th and Beyond
IPO day price action is rarely a reliable signal of long-term value, and SpaceX may be one of the most volatile IPOs in market history. Retail investors who cannot access the shares at the offer price will be faced with the choice of whether to buy what could be the first day's excitement or wait for a reasonable entry point after the closing time has expired and institutional owners may be able to sell.
The metrics that will be most important in the first 90 days are Starlink subscriber growth, implementation cadence, and any updates on government contract renewals. These are the numbers that will tell investors whether the underlying business justifies the valuation, or whether the $2 billion price tag does what Musk's TAM number does: it makes something big sound inevitable.
SpaceX may be the space business of the decade. But the best trading is done with discipline, not enthusiasm. For now, watching closely is a perfectly reasonable scenario.
