Pull up a globe and try to name a service that already touches more people than the populations of China and India combined. The answer is a broadband utility beamed from low orbit by a company that still has not finished its IPO roadshow.
That is Starlink today.
The 3.3 Billion Number
Buried in SpaceX’s pre-IPO disclosures is a footprint statistic that reframes satellite broadband. Starlink service is now available across 164 countries, territories, and other markets, collectively home to more than 3.3 billion people. That addressable population exceeds the combined headcounts of the two largest nations on Earth.
The paying base inside that footprint is compounding fast. As of March 31, 2026, Starlink counted approximately 10.3 million subscribers, up 105% from 5.0 million a year earlier. Because SpaceX reports on a per-service-line basis, the IPO paperwork notes that "the number of individual end users who access Starlink is already likely meaningfully higher than 10.3 million" since households and businesses share lines.
How They Got There
The hardware story is staggering. SpaceX operates over 9,600 broadband and mobile satellites in Low-Earth Orbit, roughly 75% of all active maneuverable satellites in orbit. Peak-hour median download speeds clock in at 225 Mbps, with latency around 25 milliseconds. Fiber-like quality, anywhere with sky.
I have been following this constellation buildout for five years now, and the V3 satellite drop is the moment I am circling. Each V3 is designed for one Tbps of downlink capacity, with a single Starship launch capable of deploying up to 60 of them. That is a twenty-fold increase in capacity per launch versus Falcon 9.
The Phone In Your Pocket Is Next
Starlink Mobile already reaches approximately 7.4 million monthly unique devices across roughly 30 countries, supported by partnerships with about 30 mobile network operators including One NZ, Optus, Telstra, Rogers, and KDDI. In 2025, SpaceX secured 65 MHz of US spectrum plus global Mobile Satellite Service licenses from EchoStar, aimed at delivering eventual 5G connectivity to unmodified handsets.
T-Mobile (NASDAQ:TMUS | TMUS Price Prediction) carries Starlink in the US, anchoring an ecosystem that lets SpaceX rent demand instead of building it.
The ARPU Tension
Here is the catch. Average revenue per user is sliding. Q1 2026 Connectivity revenue hit $3,257 million, up 31.6% year over year, but consumer revenue reflected 104.7% subscriber growth offset by a 22.9% ARPU decline. Monthly ARPU has fallen from a prior peak of $86 per month as international and lower-priced plans roll in.
SpaceX is explicit about the playbook: "Our strategy is focused on driving sustainable revenue growth and expanding our margins through operational efficiencies and technological advancements, rather than prioritizing increases in ARPU." Translation: get every connectable human on the network first, then let launch economics and V3 capacity do the margin work.
A constellation already aimed at more people than China and India combined, doubling its paid users yearly, with the phone-in-pocket layer just switching on. That is the bet investors are about to be asked to price.
