SpaceX To The Moon | The Brainstorm EP 126

The Brainstorm · ARK Invest (Brett Winton, Nick, Sam) · April 8, 2026 · Original

Most important take away

SpaceX is reportedly filing confidentially for an IPO at a rumored $1.5-2T valuation, and ARK argues the valuation is best understood not via current revenue multiples but as a “license to mint money” - capital deployed into Starlink (sized at $100-200B revenue) and AI compute satellites (potentially 60x more up-mass demand, with a million satellites already filed for) at high ROIC, with no competitor within years of matching SpaceX’s reusable launch lead. Meanwhile, OpenAI’s $122B private raise and foundation model leaders (OpenAI, Anthropic, xAI, Gemini) are chasing a ~$15-20T enterprise value pie, and Uber’s autonomous strategy only works while ride-hail stays supply-constrained near $3/mile.

Summary

Stocks, Companies & Investments Mentioned

  • SpaceX (private, pre-IPO) - rumored $1.5-2T valuation, ~$20B revenue in 2025, growing 20-25%
  • Starlink (SpaceX) - modeled at $100-200B revenue opportunity
  • xAI - acquired by/merged with SpaceX (per discussion), viewed as dilutive
  • Tesla (TSLA) - FSD/consumer-owned autonomous fleet strategy
  • NASA / Artemis / SLS - government program, criticized as cost-inefficient “jobs program”
  • Blue Origin - recently landed an orbital rocket but has not reused it
  • Amazon (AMZN) - referenced for valuation comparison
  • Meta (META) - $1.4T market cap, $200B revenue, growing 33%, used as relative-value benchmark
  • Google / Alphabet (GOOGL) - Gemini positioned as “realest” consumer AI competitor; seamless integration via Gmail, Drive, Sheets
  • Microsoft (MSFT) - noted as having “fumbled” enterprise Copilot rollout
  • Apple (AAPL) - skepticism on AI execution despite consumer data advantage
  • OpenAI - $122B raise, ~$800B valuation, ~900M weekly actives, ~$250B revenue expected per WSJ reports
  • Anthropic - listed as a real foundation-model competitor
  • Nvidia (NVDA) - cited as historical comp for underestimated revenue growth
  • Palantir (PLTR) - named as a platform-as-a-service beneficiary in the AI stack
  • Uber (UBER) - 25+ autonomous partnerships signed; strategy works while supply-constrained
  • Waymo (Alphabet) - supply-constrained, signed Uber deal in Atlanta for demand backstop
  • China space program - competing lunar base ambitions

Actionable Insights & Investment Advice

  1. How to value SpaceX at IPO: Don’t anchor on price/sales vs. Meta or Amazon. Think of SpaceX as a capital-deployment vehicle where the question is ROIC on invested capital (Starlink satellites, AI compute satellites, Starship). Current revenue is gated by up-mass, not demand. Starship reusability would drop launch cost by an order of magnitude and accelerate revenue growth dramatically.

  2. The SpaceX moat argument: SpaceX has “no company in the world with as big a lead on their competition.” They’ve reused orbital rockets for 11 years; Blue Origin just landed one but hasn’t reused it. Lead is widening, not narrowing. Cost of capital advantage is under-appreciated - even a hypothetical equal competitor couldn’t match SpaceX’s capital efficiency.

  3. Key risks to underwrite before buying SpaceX at IPO: (a) Starship reusability must work. (b) AI compute demand curve - can they convert compute advantage into monetization, or sell infrastructure-as-a-service if xAI underperforms? (c) Valuation framework - if priced on near-term revenue, upside is capped; if priced on future ROIC from reinvestment, more attractive.

  4. Bearish/skeptical framing (Nick’s view): On a relative basis, ~100x sales vs. Meta at ~7x sales growing 33% with proven AI monetization is hard to justify unless you fully believe the moat thesis. This will likely be the dominant market reaction when the S-1 drops.

  5. Foundation models (OpenAI, Anthropic, xAI, Gemini): ARK models a $15-20T enterprise value pie for foundation-model providers by 2030, driven by ~$7T in AI software spend and ~$2T accruing to foundation model layer. OpenAI at ~$800B chasing this is reasonable; not a winner-take-all market - treat like infrastructure-as-a-service where multiple players generate large cash flows.

  6. OpenAI monetization vectors: (a) Advertising - ~$100M ARR today, ARK sees ~$600-700B opportunity by 2030. (b) Agent-driven commerce - ARK models ~$9T flowing through agents globally by 2030 (~25% of global online sales). Consumer discovery is working; full-service checkout not yet.

  7. Consumer AI competition: Google/Gemini is the most credible consumer threat to OpenAI due to distribution through Gmail/Drive/Sheets. Apple skepticism remains - they appear to be following a worse playbook than Microsoft’s Copilot.

  8. Uber thesis: Strategy of 25+ autonomous partnerships works only while the market stays supply-constrained at ~$3/mile. Uber’s role is providing flex supply that Waymo cannot (Waymo can’t signal additional supply via pricing). Market size grows by an order of magnitude as price falls from $3 to $1/mile - at that point Uber’s strategy “fails catastrophically.” Tesla’s consumer-owned FSD fleet is the credible alternative that could solve the incomplete-network problem.

  9. AI compute cycle: Expect convexity/wobbles even with quasi-infinite long-run demand. Short-term funding doubts can push out timelines and delay model releases, which then delays the next demand unlock. Don’t mistake mid-cycle wobbles for the end of the cycle.

  10. Public vs. private space: The real unlock isn’t public-vs-private, it’s competition. Multiple credible competitors (SpaceX, Blue Origin, China, orbital data center players) are driving capital efficiency and acceleration that single-provider government contracting could not.

Chapter Summaries

  • Artemis, NASA & Private Space: Astronauts reaching the far side of the moon is celebrated, but SLS is criticized as legacy-parts engineering and a jobs program. The real unlock is competition (China, US, orbital data centers), not simply privatization.

  • SpaceX IPO Valuation Debate: Nick argues ~100x sales at 20-25% growth looks insane versus Meta/Max7 comps. Brett reframes SpaceX as a capital-deployment story: Starlink is a $100-200B revenue opportunity, AI compute could need 60x more up-mass (a million satellites filed), and Starship reusability would collapse launch costs.

  • SpaceX Moat & Cost of Capital: No competitor is within years of SpaceX. Blue Origin just landed an orbital rocket but hasn’t reused one. SpaceX’s cost-of-capital advantage compounds the operational lead. Open questions: Starship reusability, AI compute monetization, and length of the compute demand curve.

  • OpenAI $122B Raise & Foundation Models: The foundation-model layer is framed as a $15-20T enterprise-value opportunity. OpenAI, Anthropic, xAI, Gemini all viable. Not winner-take-all. OpenAI’s ~900M weekly actives and ~$250B projected revenue make a $2.5T outcome plausible.

  • Advertising & Agent Commerce: OpenAI ads at ~$100M ARR with a $600-700B 2030 opportunity. Agent-driven commerce modeled at ~$9T globally by 2030 (~25% of online sales). Consumer AI competition: Gemini is the real threat; Apple is skepticism-worthy.

  • Uber & Autonomous Strategy: 25+ partnerships; role is to flex supply Waymo cannot provide. Strategy works while market is supply-constrained at $3/mile, but breaks when prices fall toward $1/mile and the market expands an order of magnitude. Tesla’s FSD consumer-fleet model is the credible long-term alternative.
