SpaceX Filed Its S-1. Here’s What Happens Next.After years of speculation, SpaceX has officially filed its S-1 registration statement, giving investors their first detailed look at the company’s financials and starting the final countdown toward what could become the largest IPO in history. Reports suggest SpaceX could seek a valuation of roughly $1.75 trillion and raise between $75 billion and $80 billion, potentially eclipsing every IPO that has come before it.¹ For investors, the filing itself is not the most important event. The weeks between the S-1 filing and the first day of trading are where the real story unfolds. Here is what to expect and what I will be watching closely.
First: The SEC Review ProcessEven though the S-1 has been filed, the document is not final. The SEC will review the filing and send comments back to the company. SpaceX will then respond through amended S-1 filings that provide additional disclosures, clarify risk factors, update financial information, and sometimes reveal changes to offering terms.² For investors, these amendments are often more important than the initial filing because they reveal what regulators, bankers, and institutional investors are focusing on. Pay particular attention to: ● Changes in risk disclosures ● Lockup provisions ● Share structure ● Insider ownership ● Use of proceeds ● Any revisions to financial guidance
Next Comes the RoadshowThe roadshow is where SpaceX executives and the underwriting banks begin meeting with institutional investors around the world. Think of it as Wall Street’s due diligence process in real time. Management will spend the next several weeks explaining: ● Starlink growth ● Launch economics ● Government contracts ● AI initiatives ● Starship development ● Future profitability ● Long-term capital requirements The objective is not simply marketing. The objective is determining how much demand exists and at what valuation. Reports indicate the roadshow could begin as early as June 4–8, with pricing potentially occurring around June 11.³ This phase often tells us more than any earnings report.
Watch for Changes in the Price RangeOne of the most important signals during the roadshow is whether the proposed offering range changes. If investor demand proves stronger than expected: ● The price range may be increased ● More shares may be offered ● The valuation could move higher If demand is weaker: ● The range may be reduced ● The offering size could shrink Historically, IPOs that raise their pricing range during the roadshow tend to indicate significant institutional demand. For a company as closely followed as SpaceX, any upward revision would likely signal extraordinary demand from both institutions and retail investors.
The Index Inclusion Story Could Matter More Than Most People RealizeOne of the most interesting aspects of this IPO is the possibility of rapid index inclusion. Nasdaq recently implemented accelerated inclusion rules for certain large-cap IPOs. Under those rules, a company of SpaceX’s size could potentially qualify for Nasdaq-100 inclusion far sooner than many previous IPOs.⁴ Why does that matter? Because index inclusion creates automatic buyers. If SpaceX enters major indexes: ● Index funds must purchase shares ● ETFs tracking those indexes must purchase shares ● Passive investment vehicles become long-term shareholders This demand has nothing to do with investor opinion. It is mechanical. For a company potentially approaching a $2 trillion valuation, those flows could be enormous. Many investors underestimate how much stock demand can be generated simply because a company becomes part of the indexes millions of Americans own through retirement accounts and ETFs.
The Lockup Provisions May Be More Important Than The IPO PriceMost investors focus on the valuation. I am far more interested in the lockup terms. Traditionally, IPO investors and insiders face a 180-day lockup period before shares can be sold. However, recent reporting suggests SpaceX may utilize a staggered release structure that could permit certain shareholders to sell portions of their holdings earlier following earnings reports while maintaining longer restrictions for key insiders. Elon Musk reportedly remains subject to a substantially longer lockup period.⁵ For existing shareholders, this section of the prospectus deserves careful attention because it determines when additional supply could enter the market. Supply matters. Even great companies can experience temporary pressure when large blocks of shares become eligible for sale.
Expect VolatilityMany investors assume successful IPOs move in a straight line higher. History suggests otherwise. The first several months after an IPO are often dominated by: ● Institutional positioning ● Analyst initiations ● Lockup discussions ● Valuation debates ● Earnings expectations SpaceX may ultimately become one of the largest companies in the world, but that does not mean the stock will move smoothly during its first year as a public company. In fact, the first year may be one of the most volatile periods in the company’s history as public investors attempt to determine the appropriate valuation for: ● Starlink ● Launch services ● Defense contracts ● Starship ● Future AI initiatives Volatility should be expected, not feared.
What Investors Should Focus OnThe headlines will focus on: ● Elon Musk ● The IPO valuation ● The first-day trading pop I believe there are more important questions. Is Starlink becoming the financial engine investors hope it is?According to reports surrounding the filing, Starlink generated more than $11 billion in revenue in 2025 and is increasingly viewed as the company’s primary profit center.⁶ How much capital will Starship require?The future opportunity is enormous, but so are the capital requirements. Investors should pay close attention to management commentary regarding future investment needs and timelines. Can SpaceX expand beyond rockets and satellites?The filing reportedly highlights investments in AI initiatives, orbital computing infrastructure, and next-generation communications systems.⁷ Whether these become meaningful profit centers remains one of the most important long-term questions for investors. How quickly will passive money enter the stock?Index inclusion could become one of the most powerful drivers of demand during the first year following the IPO. The faster SpaceX qualifies for major indexes, the greater the amount of automatic buying pressure from passive funds.
The Bottom LineThe S-1 filing marks the beginning of the public phase of the IPO process—not the end of it. Over the next several weeks, investors should pay less attention to daily headlines and more attention to: ● Roadshow feedback ● Pricing range revisions ● Index inclusion developments ● Lockup provisions ● Institutional demand The IPO price will generate the most headlines. The answers to those questions will likely have a much greater impact on where the stock trades one year from now. For existing shareholders, this is no longer simply an investment story. It is a wealth planning event. The company that was once difficult to access in private markets is about to enter one of the most scrutinized periods of its history. The investors who focus on structure, liquidity, and long-term positioning rather than short-term price movements will likely make the best decisions during the transition. Next Steps:If you had the foresight, access, and conviction to invest in SpaceX before it became one of the most valuable private companies in the world, the upcoming IPO represents far more than a market event, it represents a balance sheet event. The most successful investors recognize that the work is not finished when an asset appreciates.
