Starlink doesn’t connect the unconnected—it replaces terrestrial infrastructure with orbital scale, at orbital cost.
Starlink is a satellite broadband system launched in 2019 after public announcement in January 2015. It delivers Internet via ~10,413 LEO satellites across ~160 countries, serving >12 million users. It relies on optical inter-satellite links and phased array beam-forming. It generates $11.4bn revenue but requires $10bn+ investment. It works where ground infrastructure fails—but introduces new constraints in latency, spectrum, and orbital congestion.
Starlink was announced in January 2015—not as a product, but as a facility opening in Redmond, Washington.

Orbital Dominance
Satellites began launching in 2019; by June 2026, there were ~10,413 in orbit—75% of all active maneuverable satellites.

Global Reach, Local Gaps
It serves ~160 countries, powers in-flight Wi-Fi, and accounts for three-quarters of Earth’s active maneuverable satellites.

Cost and Cashflow
SpaceX spent at least $10 billion to build it—and by end-2025, Starlink generated $11.4 billion in revenue.

The written brief1 min read
What it is and the problem it solves
Starlink is a satellite-based broadband Internet service. It solves the problem of delivering Internet access to remote, rural, maritime, and airborne users where fibre or cellular networks are unavailable or impractical.
How it works
Starlink uses a constellation of satellites in low Earth orbit. Each satellite communicates with user terminals and gateway ground stations. It employs optical inter-satellite links and phased array beam-forming in Ku/Ka bands.
What works
It delivers fixed and mobile broadband across ~160 countries and territories. It provides in-flight internet for numerous airlines. As of June 2026, it operates ~10,413 satellites and serves over 12 million subscribers.
What does not
It does not eliminate latency for real-time applications like high-frequency trading. It does not serve every location within its 160 countries equally. It does not operate without ground infrastructure: gateways remain essential.
What it changes
It shifts the economics of global connectivity by replacing geostationary latency with launch-and-maintenance scale. It redefines spectrum allocation, orbital traffic management, and regulatory oversight for mega-constellations.
Is it worth your time
Yes—if you need broadband where terrestrial infrastructure is absent or unreliable. No—if you rely on low-latency trading, consistent upload symmetry, or cost-sensitive deployment.
