At a glance: SPCX book-building closes today (June 9). Pricing Thursday June 11, after market close. Nasdaq trading opens Friday June 12 at 9:30 AM ET. Fixed price: $135/share. Shares offered: 555.6 million. Total raise: $75 billion. Implied valuation: $1.77 trillion. Oversubscription: approximately 2x ($150B in orders). Part of our Builder’s Log.

If you already read our SPCX roadshow week guide from June 4, this is the update for the final three days. Two significant things have changed since that article: the price was never a range, and the book is already full twice over.


The Fixed-Price Structure Is Unusual — Here Is Why SpaceX Did It

Standard IPOs set a preliminary price range — something like $55–$60 per share — at the start of the roadshow, then finalize the exact price on pricing day after measuring institutional demand. The range is the mechanism for price discovery.

SpaceX filed an amended S-1 on June 1 with a fixed price: $135. No range. No upper band. No floor. $135.

Fortune called this “breaking the IPO playbook.” The practical meaning:

Fixed price converts the roadshow from price discovery to distribution. Goldman Sachs, Morgan Stanley, and the syndicate are not gathering bids to figure out what the market will bear. They already know. The $135 price was set based on pre-roadshow demand signals (anchor investor conversations, pre-IPO secondary market trading, and institutional temperature checks that happen before the formal roadshow opens).

Fixed price removes allocation gamesmanship. In a standard roadshow, institutional investors bid high knowing the price will be set lower than their bid — it is a strategic game. A fixed price eliminates that dynamic. You pay $135 or you do not participate. This concentrates demand from investors who genuinely want in at $135, rather than those gaming the pricing mechanism.

It also signals Musk’s intent on valuation. SpaceX is not interested in price discovery that might find a clearing price below $1.77 trillion. The fixed $135 is a statement: this is what the company is worth, and institutional investors either agree or pass.

Whether the market agrees on June 12 is a separate question.


2x Oversubscribed: $150 Billion in Orders for a $75 Billion Deal

As of early this week, SpaceX had received approximately $150 billion in purchase orders against the $75 billion it is raising — roughly twice the deal size. For context:

  • The previous largest IPO in history was Saudi Aramco’s 2019 offering at $25.6 billion (later increased to $29.4 billion). SpaceX is raising more than twice that in a single offering.
  • The $22.5 billion retail tranche (~30% of the deal) is handled through Robinhood, Fidelity, Schwab, SoFi, and E*TRADE. If retail demand mirrors institutional, the retail tranche is also significantly oversubscribed.
  • Most retail investors who submitted conditional purchase requests will receive a fractional allocation. Many will receive nothing and buy SPCX in the open market on Friday.

Oversubscription at this level typically means two things on trading day:

  1. Opening price above $135. When demand significantly exceeds supply, market makers set the opening print above the IPO price to absorb that excess demand. Depending on how aggressive early buyers are, SPCX could open 10–30% above $135 — or more.
  2. Subsequent retracement. Morningstar published a fair value estimate that puts SpaceX’s intrinsic value at roughly half the $1.77 trillion IPO valuation. Hyped tech IPOs at inflated valuations frequently retrace 20–40% within the first 90 days. The two-day lockup for IPO share flippers accelerates this.

This is not investment advice. But the asymmetry is worth noting: the opening print on June 12 will likely not be the best entry price for SPCX if you are a patient investor.


What Actually Changed When the Nasdaq Selloff Hit

On Sunday, June 7, the Nasdaq Composite fell 4.2% in a broad selloff — chip stocks led, but the decline spread across the index.

Analysts tie this directly to the IPO. To buy $75 billion in new shares, investors need $75 billion in cash. Most of that cash lives inside other equities. The mechanics: sell existing stocks → receive cash → use cash to buy SPCX. This is happening at scale, concurrently, across retail and institutional investors.

Additional capital pressure compounds the timing. Alphabet issued $85 billion in secondary shares in the past week. OpenAI and Anthropic are in the pipeline behind SpaceX. Q2 end-of-quarter portfolio rebalancing is running simultaneously. The capital rotation is unusually compressed.

For builders: the selloff has no direct effect on API availability or pricing from any AI lab. It is financial market noise. But it does surface as macro context if your company is carrying GOOG, MSFT, AMZN, or NVDA on the balance sheet.


What Actually Changes for Builders When SPCX Goes Public

The stock price is not the builder-relevant event. These three things are:

1. The Anthropic Contract Becomes Quarterly Public Disclosure

SpaceX’s S-1 disclosed that Anthropic agreed to pay $1.25 billion per month for exclusive access to the Colossus 1 data center’s compute output. The contract runs through May 2029. Total committed value: approximately $45 billion, subject to 90-day termination provisions.

Right now, this exists as a static disclosure in the S-1. Once SPCX is a public company with SEC reporting obligations, the status of this contract appears in every quarterly 10-Q:

  • Is the contract on schedule?
  • Has Anthropic exercised expansion options (300 MW was the initial commitment; “multiple gigawatts” in space was described as interest, not a signed deal)?
  • Has Anthropic given 90-day termination notice?
  • Is there any contract dispute?

The Q3 2026 earnings call (likely November 2026) will be the first quarterly public update on the Anthropic-Colossus relationship. If you are building on Claude and thinking about compute stability, set a calendar reminder for that earnings date when it is disclosed post-IPO.

2. The SpaceX-Cursor Acquisition Closes ~July 12

SpaceX has the right to acquire Cursor within 30 days of the IPO. At the current IPO date of June 12, that 30-day window opens June 12 and closes July 12.

Cursor runs approximately 50–67% of Fortune 500 AI coding workflows. The current Cursor model routing uses Claude, GPT, and other providers behind a unified interface. If the acquisition closes and xAI’s Grok model becomes the default backend for Cursor (the plausible direction, given xAI is SpaceX’s AI subsidiary), Claude Code shifts from one of several options in a popular IDE to a direct competitor to the dominant enterprise AI coding tool.

This competitive realignment does not happen overnight. Post-acquisition model migration typically takes 90–180 days. But the clock starts on July 12. Our earlier guide on the SpaceX-Cursor deal covers the implications in detail.

3. The AI Segment Financials Are Now On Record

The S-1 disclosed that SpaceX’s AI segment (Colossus 1, xAI’s cluster) posted a $2.47 billion operating loss in Q1 2026 on $12.7 billion in AI capex for 2025 and $7.7 billion in Q1 2026 AI capex alone. These are large numbers relative to the revenue that AI segment generates.

As a public company, those numbers will update quarterly. If the AI segment’s losses narrow (because the Anthropic contract revenue comes online more fully), that signals Colossus is operating at capacity. If losses widen, it may indicate SpaceX is building faster than contracted revenue justifies — which eventually creates pricing pressure on compute customers.


What to Watch on June 12

The opening print. The IPO price is $135. The opening print — set by the Nasdaq market maker before the first official trade — will be the first real price signal. Above $150 signals the oversubscription is driving day-one momentum. Below $135 would be unusual but not unprecedented in a market still rotating out of equities.

Volume in the first 30 minutes. Thin-volume IPO openings are more volatile than high-volume ones. SPCX’s 30% retail allocation means a large number of small holders who may sell quickly if the stock pops or sell on disappointment. Watch for whether the first hour’s trading is orderly or jerky.

The Anthropic-SPCX first analyst note. Within a few days of IPO, major bank analysts covering SpaceX will publish initiating coverage reports. These reports will include their own assumptions about the Anthropic contract value, Colossus capacity utilization, and orbital compute timeline. The consensus model that emerges from those analyst notes will be the market’s baseline for evaluating the AI segment going forward.

Whether the stock stays above $135 through end of day. An IPO that closes below its offering price on day one is a signal. Not a catastrophe, but a signal that demand at $1.77T is thinner than the oversubscription number suggested. The $150B in orders does not all convert to $135 holders if some of that demand was speculative at any price.


The Morningstar Warning

Morningstar published a fair value estimate on SpaceX at the start of the roadshow. The headline: $1.77 trillion is “nearly twice fair value” by their model.

Their reasoning: SpaceX’s profitability is concentrated in Starlink. The rocket launch business has improving economics but has not hit scale profitability. The AI segment is currently burning $2.47 billion per quarter. The Anthropic contract covers revenue, but the capex required to run and expand Colossus has not been recovered. The valuation at $1.77T implies that orbital AI compute becomes a dominant revenue stream within this decade — a bet Morningstar does not underwrite at that multiple.

This does not mean the stock is a bad investment. It means the valuation reflects future potential, not current operations. That is typical for transformative infrastructure companies. Amazon Web Services was unprofitable for years before it dominated cloud infrastructure. If SpaceX’s orbital compute thesis plays out at scale, $1.77T may look cheap in 2035.

For builders: the financial market dynamics around SPCX are not directly your concern. But understanding that the stock is priced for a future that has not yet arrived helps calibrate how to interpret SpaceX’s announcements and partnerships in the post-IPO period. Every quarterly earnings call will be judged against the orbital compute thesis. Anthropic’s role as the first major contracted customer is central to that narrative.
