SpaceX (SPCX) – Quick S-1 Summary

SpaceX (SPCX) – Quick S-1 Summary

Definitions:

  1. Falcon 9 is its rocket system that launches satellites, people & cargo into orbit.
  2. Falcon Heavy is Falcon 9 w/2 extra rocket boosters for much larger launch capacity.
  3. Dragon is its spacecraft that carries people & goods.
  4. Starship is its next-gen rocket currently moving from testing to commercial use.

A lot of Launch Segment Firsts:

  1. 2008 -- First private company to successfully launch a liquid-fuel rocket into low Earth orbit.
  2.  2012 -- First private company to guide & dock a spacecraft at the International Space Station.
  3. 2015 -- First to use a rocket's own downward thrust to land (propulsive landing).
  4.  2017 -- First rocket re-flight.
  5. 2020 -- First private company to dock astronauts at the International Space Station.

Dominant Launch Segment Positioning & Roadmap:

  1. Falcon 9 has a 99%+ mission success rate. This is 85% cheaper per kilogram to launch than average (per NASA). The lead has only grown from there. Falcon Heavy is 92% cheaper per kilogram than the average substitute.
  2. Cost edges come from things like the top piece of their rocket (the upper stage) costing SpaceX $5M to build vs. $50M for legacy competition. The power of vertical integration.
  3.  Falcon 9 + Falcon Heavy have an 80% share of global mass to orbit since 2023.
  4. Starship is next. This will come with a fully reusable design that can immediately refuel and launch again. Starship can also carry 3x-4x the weight vs. Falcon Heavy in low Earth orbit... making it perfect to deploy giant satellites & data centers. They hope this will boost their cost per kilogram lead from 92% with Falcon Heavy to 99% for Starship use cases.
  5.  They aim to charge $90M/launch on Starship, which is far cheaper than other options.
  6. A lot of launch capacity right now is dedicated to Starlink rather than 3P customers. This gives them a lot more flexibility to cater to demand while servicing their own needs. It also means they're not stuck with excess capacity if a partner cancels or delays a launch. They can use it for Starlink.
  7. While margins for the segment are pressured due to investments right now, they make more than $67M per launch & it costs them $15M to run it. The unit economics are good & should support healthy long-term margins.

Starlink & Connectivity:

  1.  2022 -- First company to build "consumer-grade phased-array terminals." These are flat, stationary satellite dishes that use software to steer radio signals so they can track moving satellites without actually moving themselves. That simplifies design, lowers cost & improves durability.
  2. 2025 -- First commercially scaled direct-to-mobile satellite cluster... bypassing the need to connect to cell tower service that is often unavailable.
  3. Starlink has grown from just over 2M users in 2023 to 10M+ in Q1 2026.
  4. Extending connectivity to deeply remote areas & using it for mission-critical things like emergency response around the world are resonating (not to mention commercial opportunities with airlines).
  5. One thing to keep an eye on is pricing power. They cut pricing from $99 in 2023 to $81 for 2025. It fell from $86 in Q1 2025 to $66 in Q1 2026. While that's not amazing, it was to take advantage of excess capacity already in place & to steal share faster. It's also a byproduct of mix-shift to lower ARPU countries.
  6. Starlink has a 63% EBITDA margin.
  7. The larger, more distributed low orbit satellite base creates a 95% latency edge vs. the competition due to closer proximity to the point of consumer connection. Setup is way easier, there are no cancellation fees & customers can easily pause service whenever they want to. Pay when you need to use it.
  8. While overall cost for Starlink is a bit higher than some more antiquated solutions, the vastly better performance means cost per megabit is a lot lower.

xAI:

  1. Part of SpaceX as of January 31st.
  2. Grok has 550M monthly active accounts.
  3. These investments are why GAAP EBIT swung from a 2024 gain to a 2025 loss. Connectivity is deeply profitable. Launch Systems aren't losing nearly as much.
  4. Floated a $28.5 trillion TAM for this segment. That’s not a typo.. but take with a very large grain of salt.
  5. Anthropic will pay SpaceX $1.25B per month for access to compute within its AI segment. That equates to $15B per year for a segment that did just $3.2B in 2025 revenue.

Quick Take:

I’m not interested in owning this company at the current market cap. I find the business deeply impressive and I think there are a lot of extremely attractive assets here. I just won't invest in them unless I can do so at what I find to be the right price. I think I'm going to keep following this company and covering major news so I’m prepared to hopefully own it in the future if it's not quite so expensive. There’s a decent chance that never happens, but I need to stay disciplined and accept that as a risk.
