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.

§01

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.

§02

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.

All three figures are verbatim from the S-1.

~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.

§03

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.

FIG. 4.3 100,000 H100 GPUs, to scale
FILLED:  0 GPUs · POWER: > 1 GW (Colossus I + II) · BUILD: 122d / 91d
Each filled square is one H100 GPU. The S-1 quantifies Colossus in megawatts (>1 GW combined with Colossus II), not GPU count — the 100,000 figure is widely reported by Wired and Reuters but is not stated verbatim in the filing.

↳ 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.

THE MISSION FIG. 5.0
EARTH MARS

Make life
