WHAT YOU NEED TO KNOW RIGHT NOW
● SPCX is trading at $135 — flat to IPO price. No pop. This is unusual for a 3.5x oversubscribed deal
● Demand was $250B+ — retail alone surpassed $100B. Oversubscribed 3.5-4x. Why no pop?
● The float is 4% — 555M shares out of 13.1B total. Thin float usually amplifies moves, not suppresses them
● MSCI inclusion starts tomorrow (June 13) — structural passive buying begins day 2 regardless of where it opens
● What to do if you missed the allocation: do not chase. Read the decision framework below
Why Is SPCX Flat When Demand Was $250 Billion?
This is the question every retail investor is asking right now. $250 billion in demand. Retail orders alone exceeding $100 billion. Oversubscribed 3.5 to 4 times. And the stock opens flat at $135. How?
Four reasons, in order of importance:
1. The fixed price mechanism means there was no underprice to pop from
Traditional IPOs use a price range ($120-$140) and then set a final price. If they set $130 and demand is enormous, the stock pops to $160 on day one — investors who got allocations at $130 are instantly up 23%. SpaceX skipped the range and went directly to a fixed $135. There is no "underpriced allocation" to pop from. The IPO price was already set at where the company believed maximum sustainable demand existed. A flat open means the market agrees with that assessment — not that there is no demand.
2. Valuation at 94x EBITDA leaves no room for multiple expansion
SPCX priced at 94x its 2025 adjusted EBITDA of $6.6 billion. Nvidia — the most valuable AI infrastructure company in the world with 50%+ margins — trades at roughly 45-50x EBITDA. SpaceX is priced at twice Nvidia's multiple with a fraction of Nvidia's margin profile and with a loss-making xAI segment dragging the consolidated numbers. There is not much room for buyers to argue the stock deserves to trade even higher on day one. The aggressive pricing was deliberate — SpaceX and its bankers wanted to capture the full valuation in the IPO, not leave it on the table for day-one flippers.
3. Institutional investors are not flipping — they are holding for index inclusion
The institutional buyers who got allocations are not selling. They are holding because MSCI inclusion begins tomorrow (June 13) and Nasdaq-100 inclusion comes on or around July 7. Both events create forced buying from passive funds. Institutions are sitting on their allocations waiting for that structural demand to push the price up, then potentially trimming. No institutional selling pressure means no crash; no euphoric retail pile-on means no pop. Equilibrium at $135.
4. The 4% float means the price is extremely sensitive to order flow direction
Only 4% of SPCX shares — 555 million out of 13.1 billion — are in the public float today. Any significant sell order moves the price down; any significant buy order moves it up. With institutional holders staying put and retail buyers uncertain about whether to pay $135 on the open market, the order book is in equilibrium. This could break in either direction quickly — a large passive fund front-running tomorrow's MSCI inclusion could push it above $140 before the close.
What SPCX's Flat Open Signals for Anthropic and OpenAI
This is the angle that most retail-focused coverage is missing. SPCX is not just a SpaceX stock — it is a benchmark for how the public markets value loss-making AI infrastructure companies in mid-2026. The result on day one sends a direct signal to every CFO and banker working on the Anthropic and OpenAI public listings.
| Scenario |
SPCX day-one outcome |
Signal for Anthropic/OpenAI |
| Flat ($130-$140) |
Market accepts the valuation but is not euphoric |
Proceed on current timeline. Institutional appetite for AI IPOs exists but is rational, not frothy. Price carefully |
| Strong pop (+20%+) |
Market is euphoric about AI infrastructure |
Accelerate timelines. Risk-on cycle supports even higher multiples. Both companies could price above their current valuation targets |
| Below IPO price |
Market rejects 94x EBITDA for loss-making AI companies |
Both Anthropic and OpenAI would need to delay, reprice, or restructure. The AI IPO window narrows significantly |
A flat open at $135 is the base case — the market is saying "we accept this price, we are not panicking, and we are not in a frenzy." For Anthropic (targeting October 2026) and OpenAI (targeting September 2026), a flat SPCX open is the best possible outcome. It confirms institutional appetite for AI listings without creating a frothy comparison that would force their bankers to price them against an inflated SPCX pop. It says: price carefully, proceed on schedule, the window is open. For the full context on both upcoming listings see our OpenAI IPO S-1 analysis and Anthropic IPO timeline.
The Structural Story Still Plays Out This Week
A flat day-one open does not mean nothing happens with SPCX this week. Two structural events create forced buying pressure that is independent of whether retail sentiment is bullish or bearish:
Tomorrow June 13 — MSCI inclusion starts
Every passive fund tracking MSCI's Global Standard Indexes begins buying SPCX tomorrow. These are mechanical purchases — fund managers are not making investment decisions, they are rebalancing to match their benchmark. The amount of forced buying depends on SPCX's weight in the index, which is determined by its float-adjusted market cap. At a 4% float and $1.77T total market cap, the float-adjusted cap is approximately $70 billion. MSCI-tracking funds managing trillions in assets must hold SPCX in proportion to that weight.
~July 7 — Nasdaq-100 eligible
Nasdaq amended its rules in May 2026 to allow megacap IPOs to join the Nasdaq-100 after just 15 trading days. Based on June 12 listing, SpaceX is eligible for inclusion on or around July 7. QQQ — the world's most-traded ETF by volume — and every other Nasdaq-100 tracker must buy SPCX at that point. This is wave two of forced institutional buying, arriving roughly 3.5 weeks after listing.
Decision Framework - Should You Buy SPCX Today on the Open Market?
Do not buy if:
- You are buying because you fear missing out on a pop that may not come
- You have not read Morningstar's $780 billion fair value estimate (vs $1.77T IPO price)
- You cannot hold for at least 12-18 months through potential volatility
- You are not comfortable with Musk controlling 85% of votes regardless of your ownership
- A significant portion of your portfolio would be in a single stock
Consider buying if:
- You believe Starlink reaches 50M+ subscribers by 2028 and the AI compute revenue is durable
- You want AI infrastructure exposure that is not pure-play model risk (vs buying Anthropic/OpenAI direct)
- You can hold through the June 2027 lockup expiry — the real structural test for the stock
- A position sized appropriately (not more than 3-5% of portfolio) fits your risk profile
- You are comfortable with ARK's $2.5T by 2030 scenario as a plausible if not certain outcome
The honest take:
Buying SPCX at $135 today on the open market means paying the same price institutional investors paid after two weeks of roadshow meetings and detailed S-1 analysis. You have access to the same S-1 they do. The question is not whether the IPO price is "fair" — it is whether you believe SpaceX's business is worth $1.77 trillion today and more in the future. Morningstar says $780 billion. ARK says $2.5 trillion by 2030. Neither is certainly right. Size the position accordingly.

Frequently Asked Questions
Why did SPCX open flat despite $250 billion in demand?
Three reasons: SpaceX used a fixed price rather than a price range, eliminating the underpricing discount that typically causes first-day pops. The 94x EBITDA valuation left no room for buyers to argue the stock deserves an even higher multiple on day one. And institutional holders are sitting on their allocations awaiting MSCI inclusion tomorrow rather than selling into early demand. A flat open at a $135 fixed price for the most oversubscribed IPO in history is not a negative signal — it is a rational market pricing a company exactly where the bankers and management wanted it.
What happens to SPCX when the lockup expires in June 2027?
The 366-day lockup expiring around June 13, 2027 is when employees, early investors, and insiders can sell their shares for the first time. With Musk holding approximately $688 billion worth of SpaceX shares at the IPO price, and thousands of SpaceX employees holding significant equity, the lockup expiry could see the largest potential insider selling event in market history. Morningstar called this "Max Q" — the moment of maximum structural pressure on the stock. It does not mean the stock will crash; it means the sell-side supply increases dramatically at that point, and the stock's price at lockup expiry will determine whether insiders choose to sell or hold.
What does SPCX's flat open mean for Anthropic and OpenAI IPO timing?
A flat open is the best-case outcome for both companies' IPO teams. It means: institutional appetite for AI listings exists, the market is not in a frenzy (which would create dangerous pricing comparisons), and the window for Q3-Q4 2026 listings remains open. OpenAI targeting September and Anthropic targeting October 2026 both proceed on schedule based on today's outcome. A below-IPO open would have forced both to reconsider. A massive pop would have created pressure to price even more aggressively, increasing downside risk at listing.
Is SPCX a buy at $135 today?
This is not financial advice — size and risk tolerance matter enormously. The honest framework: you are buying at 94x EBITDA for a company with one profitable segment (Starlink) and a loss-making AI division. The structural demand from MSCI and Nasdaq-100 inclusion creates near-term price support. The June 2027 lockup expiry is the next major risk event. Morningstar's $780 billion fair value and ARK's $2.5 trillion 2030 target define the range of plausible outcomes. Where in that range you believe SpaceX lands determines whether $135 is cheap or expensive.
