Starlink (SpaceX)

SpaceX needed money to build Starship and colonise Mars. Rocket launches were profitable but episodic — dependent on NASA contracts, satellite deployments, and the pace of commercial space demand. Elon Musk's solution was structural: put enough satellites in low Earth orbit to provide high-speed internet to anyone on Earth, generating a subscription revenue stream that would be continuous, scalable, and largely independent of the geopolitical variables that complicated government launch contracts. The concept was announced in 2015. The first prototype Starlink satellites launched in 2018. The first 60 operational satellites went up in May 2019 aboard a Falcon 9 rocket.

Traditional satellite internet suffered from latency that made video calls impossible: geostationary satellites orbit at 35,786 kilometres, and the round-trip light travel time alone created delays of 600+ milliseconds. Starlink's constellation orbited at 550 kilometres — close enough for latency of 20-40 milliseconds, comparable to ground-based broadband. The "Better Than Nothing Beta" public launch in October 2020 — at $99 per month for residential service plus $499 for the antenna — attracted 10,000 users immediately. The product worked: rural users who had never had broadband-speed internet were receiving 100+ Mbps download speeds via a pizza-box-sized terminal pointed at the sky.

When Russia invaded Ukraine in February 2022, Ukrainian forces relied heavily on Starlink for battlefield communications — coordinating drone strikes, artillery, and logistics using the satellite network after terrestrial infrastructure was destroyed. The US government and NATO allies shipped thousands of Starlink terminals to Ukraine. The episode made Starlink simultaneously the most visible military satellite communication system in the world and a source of significant controversy: Elon Musk's decisions about Starlink coverage in Crimea directly affected military operations, giving a private company unprecedented influence over a conflict between nations. Musk's political interventions — including reported conversations with Russian officials — generated extraordinary scrutiny.

Starlink reached 4.6 million active subscribers by end of 2024, generating $7.7 billion in revenue — 58% of SpaceX's total. The subscriber base included residential customers in 160+ countries, maritime operators, airlines (United, Southwest, Hawaiian among many), and government clients through the Starshield military satellite division. In July 2025, T-Mobile launched "T-Satellite" using Starlink's Direct-to-Cell technology, extending satellite coverage to standard smartphones across North America without a special terminal. The de minimis exemption that had allowed Starlink to ship hardware cheaply globally had no relevance here — Starlink's growth was in service subscriptions.

Starlink surpassed 10 million active subscribers in February 2026, having doubled its user base in twelve months. Revenue reached $11.4 billion in 2025 — a 49% year-on-year increase — with operating profit of $4.42 billion: Starlink was the only profitable segment in SpaceX's business, subsidising the $6.35 billion operating loss of the AI division (following the xAI merger). SpaceX filed a prospectus for a Nasdaq IPO seeking to raise $75-80 billion at a $1.5-2 trillion valuation. Elon Musk retained 85% of voting control through Class B shares. The satellite internet service that had been conceived to fund Mars colonisation had become the most valuable broadband subscription business in the world.
