Starlink/SpaceX IPO: Prospectus Filed — and Now Trading as SPCX (Updated June 2026)
Key Takeaways
- The S-1 prospectus is the next domino. SEC rules require it 15+ calendar days before marketing — with the roadshow set for the week of June 8, expect the public prospectus to drop between May 15 and May 22.
- SpaceX just finished its three-day analyst meeting (April 21–23). Wall Street has now seen the financials. The institutional book starts forming this month.
- Starlink crossed 10 million subscribers in February 2026 — adding the last million in just 53 days. 2025 revenue: $11.4B. 2026 projected: $15.9B with ~$11B in EBITDA.
- Retail allocation is still tracking at ~30% of the offering — three to six times the typical IPO. Plus 1,500 retail investors are being flown to Starbase June 11 for an in-person event.
- If you haven’t opened brokerage accounts yet, this is your last clean window. Once the prospectus hits, IOI windows open fast and verification delays cost you allocations.
I’ve been tracking this IPO since the confidential filing dropped on April 1, and we’re now entering the window where things stop being theoretical. The SEC’s calendar math is unforgiving — and it tells us almost exactly when the prospectus has to go public.
Let me walk you through what happened this week, what’s about to happen, and exactly how I’d position if I were starting from zero today.
What Happened This Week
Three things mattered.
First, the analyst meetings wrapped. From April 21 through April 23, SpaceX hosted Wall Street’s sell-side analysts and select institutional investors behind closed doors. These meetings are where companies hand over the long-term financial model and walk analysts through every revenue line — Starlink, Starshield, launch services, the xAI integration, the works. The analysts who attended will now spend the next six weeks publishing initiation reports timed to the IPO.
Second, the timeline is now locked. SpaceX is targeting the week of June 8 to launch its investor roadshow. SEC regulations require the registration statement to be public at least 15 calendar days before marketing begins. Do the math: the prospectus has to be public by May 22 at the latest, and most likely between May 15 and May 22. We are 11 to 18 days from seeing real, audited Starlink financials for the first time in history.
Third, the retail event got a date. SpaceX confirmed plans to host 1,500 retail investors at Starbase on June 11, immediately after the roadshow kicks off. This is a deliberate signal — Musk wants the optics of a populist IPO, and the company is reportedly opening allocations to retail investors in the UK, EU, Australia, Canada, Japan, and Korea in addition to U.S. retail.
What This Means for Retail Investors
Here’s the strategic read. SpaceX is structuring this IPO to be the most retail-friendly large-cap offering in history — and that’s not charity, it’s calculation.
Most institutional IPOs allocate 5% to 10% to retail. SpaceX is targeting 30%. On a $75 billion raise, that’s roughly $22.5 billion of stock earmarked for individual investors. Sounds like a lot. It isn’t. There are an estimated 60+ million U.S. retail brokerage accounts, and demand for this offering will not be polite.
What that means in practice: your individual allocation will almost certainly be partial. If you indicate interest for 100 shares, expect to receive a fraction. The investors who get meaningful allocations will be the ones who:
- Have accounts at multiple participating brokers
- Meet each broker’s eligibility threshold (asset minimums, trading history)
- Submit their indication of interest (IOI) early and at the maximum size their account permits
The window between prospectus filing and IPO pricing is roughly four to five weeks. That’s your runway to get positioned. After May 22, you’re playing catch-up.
Valuation Update
The target range hasn’t moved much in the past two weeks: $1.75 trillion to $2 trillion post-money. Reports from late April suggest the deal team is leaning toward the higher end of that range, with a rumored offer price near $525 per share.
To put $1.75T in context: that puts SpaceX comfortably in the top ten companies on earth by market cap on day one of trading. For comparison, that’s larger than Berkshire Hathaway, Tesla, and Eli Lilly — and roughly tied with Saudi Aramco.
The valuation case rests almost entirely on Starlink. Here are the numbers analysts are working with:
- 2025 Starlink revenue: $11.4B (up ~50% YoY)
- 2025 Starlink EBITDA: $7.2B (~63% adjusted margin)
- 2026 projected revenue: $15.9B
- 2026 projected EBITDA: ~$11B
- Subscriber growth: 1.5M new subs/month, 10M total as of February 2026
One caveat I’d flag: average revenue per user (ARPU) has compressed about 18% over the last two years, from roughly $99 to $81 per month. Total revenue is still ripping because subscriber growth is faster than the price decline — but the ARPU trajectory is something institutional investors will scrutinize during the roadshow. If you see analyst notes attacking the multiple, ARPU compression is where they’ll start.
At a $1.75T valuation against ~$15.9B in 2026 revenue, you’re looking at roughly 110x trailing revenue. That’s a number that requires you to believe in the long-term Starshield (military), aviation, maritime, and direct-to-cell businesses, not just consumer broadband. The Motley Fool, ARK, and Bloomberg have all published recent pieces arguing this multiple is justified given the moat. Plenty of others are skeptical. Both views are reasonable. You’ll need to read the S-1 to form your own opinion.
How to Prepare Now
This is where most retail investors leave money on the table. Don’t be most retail investors.
Step 1: Open accounts at multiple participating brokers. The brokers confirmed for SpaceX IPO retail allocation are [Fidelity](https://www.fidelity.com/?ref=aedilis), Charles [Schwab](https://www.schwab.com/?ref=aedilis), Robinhood, SoFi, and Interactive Brokers. Open at least two. If you only have one, you’re betting your entire allocation on whether that one broker’s allocation algorithm picks you. Diversify the broker risk the same way you’d diversify portfolio risk.
Step 2: Hit each broker’s eligibility threshold. Fidelity requires either $100,000 or $500,000 in household assets depending on the offering, plus a minimum 36-month trading history with at least 36 trades for some IPOs. Schwab requires $250,000 in household assets or 36 qualifying trades over the past 12 months. Robinhood and SoFi are the most retail-friendly — anyone with a funded account can typically participate, though allocations skew small. If you’re under the asset thresholds at the bigger brokers, prioritize Robinhood and SoFi.
Step 3: Sign up for IPO alerts immediately. Every one of these brokers has an IPO alert system. Sign up. Now. Before the prospectus drops.
Step 4: Fund your accounts above your IOI size. When you submit an IOI, the broker typically requires the cash to be in the account or readily available. Don’t get caught moving money during the IOI window.
Step 5: Read the actual S-1 when it drops. I’m going to write a full breakdown the day it goes public. But you should read it yourself. Pay particular attention to the dual-class share structure (Musk reportedly retains ~79% voting control with ~42% economic ownership), the related-party transactions section, and the use-of-proceeds disclosure.
Frequently Asked Questions
When exactly will the SpaceX/Starlink IPO happen?
Based on the current timeline, the public S-1 prospectus is expected between May 15 and May 22, 2026. The investor roadshow begins the week of June 8. IPO pricing and first day of trading is most likely between June 18 and June 30, 2026 — though dates can slip if market conditions deteriorate.
Will Starlink IPO separately, or is it folded into SpaceX?
This is the key clarification many retail investors miss: SpaceX is going public, and Starlink is a wholly-owned subsidiary inside that offering. There is no separate Starlink ticker on the table right now. When you buy SpaceX stock, you own a proportional slice of Starlink. A separate Starlink spin-off may happen years down the road, but it is not part of this IPO.
Can I buy SpaceX shares before the IPO through secondary markets?
Yes, accredited investors can buy pre-IPO shares through platforms like Forge Global, EquityZen, and UpMarket. Recent secondary market trades have implied valuations between $400B and $500B — meaningfully below the IPO target. If you’re an accredited investor and you have conviction, secondary market shares may offer better entry. If you’re not accredited, the IPO is your entry point.
How much should I allocate to a single IPO position?
I’m not going to tell you a number — your situation is yours. But I’ll give you the framework I use: any single-name IPO position should be sized so that a 50% drawdown in the first 12 months would not change your retirement trajectory. IPOs are volatile. The largest-ever IPO does not get a pass on that math.
What’s the biggest risk I should be watching?
Two risks. First, valuation: at 110x revenue, this offering is pricing in a decade of execution. Second, key-person risk: Musk’s voting control means his attention, decisions, and political exposures all flow directly into the stock. Diversify accordingly.
Bottom Line
The next two weeks are the calm before the storm. The prospectus drops, the roadshow starts, and the largest IPO in market history prices roughly 45 days from now. If you want a meaningful allocation, the work to do is right now: open accounts, hit eligibility thresholds, and sign up for alerts. After May 22, you’re competing with everyone who waited.
I’ll be back with a full breakdown the day the S-1 hits.
