How big
is big?
Six numbers from SpaceX's S-1 — the largest IPO in history — anchored to things you already know the size of.
Twenty-eight
point five
trillion.
SpaceX's S-1 claims a Total Addressable Market of $28.5 trillion [1] — which the filing itself calls "the largest actionable total addressable market in human history."
That's roughly the entire annual GDP of the United States [2] , and about 27% of world GDP [3] . One company's market opportunity, sized to consume a quarter of the global economy.
93%
is AI.
The "space company" framing buries the actual story. Of the $28.5T, $26.5 trillion (93%) is in AI markets — $22.7T enterprise apps, $2.4T AI infrastructure, $760B consumer subscriptions, $600B digital ads.
The actual Space segment is $370 billion — just 1.3% of the total. Connectivity (Starlink) is another $1.6T at 5.6%. SpaceX, on its own filing, reads as an AI bet that also does rockets.
↳ The S-1's TAM estimate explicitly excludes China and Russia. Sub-segment values come straight from the filing's prose.
Owning
the cosmos.
The S-1 puts it plainly: SpaceX has "launched more than 80% of mass to orbit for the world each year" since 2023, at a "99% mission success rate" [1] .
Falcon has flown ~620 orbital launches. ~540 of them used a previously-flown booster.
~87%
are reuses.
540 of 620 Falcon 9 launches used a flight-proven booster. Reusable orbital rockets are no longer the future — they're the default at SpaceX, and only at SpaceX.
Nine thousand,
six hundred
satellites.
As of March 31, 2026, SpaceX operates ~9,600 Starlink satellites in LEO [1] — which the filing notes is "approximately 75% of all active maneuverable satellites in orbit."
They serve ~10.3 million Starlink subscribers across 164 countries, territories, and markets, plus another ~7.4 million monthly mobile devices. ~17.7M people, roughly the population of the Netherlands, get internet through one company's satellites.

$1.25 billion
a month.
Buried in the S-1: Anthropic has agreed to pay SpaceX $1.25 billion per month through May 2029 [1] for compute capacity on the COLOSSUS data centers. About $15B/year, totalling roughly $45 billion over the contract [2] .
SpaceX is renting GPUs to the developer of Claude — a direct competitor of its own Grok chatbot. The check makes Anthropic both a major customer and a major rival.
↳ The reported 100,000-H100 figure for Colossus comes from Wired and Reuters [2] — it is not in the S-1 itself. The S-1 quantifies compute in megawatts: Colossus + Colossus II together exceed 1 GW. SpaceX's plan is more dramatic still: "deployment of 100 gigawatts per year via satellites… approximately one million metric tons to orbit" annually.
Make life
multiplanetary.
"Our mission is to build the systems and technologies necessary to make life multiplanetary, to understand the true nature of the universe, and to extend the light of consciousness to the stars."
