Six years after SpaceX opened Starlink to the public, the competitive damage to legacy satellite broadband is no longer a trend — it's a rout. Viasat, once the dominant name in US satellite internet, has shed 81% of its fixed broadband subscriber base since November 2020, dropping from 603,000 customers to just 115,000. The numbers tell a story of a market that moved faster than any incumbent could adapt to.
The Subscriber Collapse, Year by Year
The erosion didn't happen overnight, but it accelerated sharply as Starlink expanded coverage and dropped hardware costs. According to verified public filings and industry tracking, Viasat's US fixed broadband decline unfolded in clear stages:
| Period | US Subscribers | Change |
|---|---|---|
| September 2020 (pre-Starlink) | 603,000 | — |
| May 2021 | 590,000 | −13,000 |
| December 2024 (Q1 FY2025) | 257,000 | −346,000 |
| Q1 2025 | 189,000 | −68,000 |
| March 31, 2026 | 130,000 | −59,000 |
| Q2 2026 (latest) | 115,000 | −81% from peak |
The early losses were gradual — Viasat shed roughly 13,000 subscribers in the first six months after Starlink's beta launch. But as SpaceX scaled its constellation and Starlink's waitlist cleared, the pace of defection accelerated dramatically. From December 2024 onward, Viasat was losing tens of thousands of subscribers per quarter.
Why Legacy Satellite Couldn't Compete
The core problem for Viasat — and its geostationary satellite peers — was structural, not operational. Geostationary satellites orbit at roughly 35,000 kilometers above Earth, producing latency in the 600–700ms range that made real-time applications like video calls and gaming frustrating at best. Starlink's low-Earth orbit constellation, sitting at around 550 kilometers, delivers latency in the 20–40ms range — closer to a cable connection than a traditional satellite service.
Pricing compounded the problem. Viasat's plans historically came with data caps and throttling policies that frustrated rural customers who had no other option. When Starlink arrived offering uncapped, low-latency broadband at a competitive monthly rate, the value proposition for staying on a legacy geostationary service essentially evaporated.
Viasat did attempt to respond — its ViaSat-3 constellation, designed to dramatically increase capacity and reduce per-bit costs, was intended to close the competitive gap. But the program suffered a significant setback in 2023 when an antenna on the first ViaSat-3 Americas satellite failed to fully deploy, limiting its capacity. That technical stumble left Viasat without the upgraded network it needed precisely when Starlink was accelerating its own expansion.
The Broader Market Signal
Viasat's subscriber trajectory is the clearest public data point yet on how thoroughly Starlink has restructured the satellite broadband market. According to industry tracking, Starlink surpassed 4 million subscribers globally well before 2025 and has continued expanding into maritime, aviation, and government segments — markets that Viasat also competes in, though Viasat has historically been stronger in those enterprise and government verticals than in consumer fixed broadband.
The consumer fixed broadband segment, where Viasat's losses are concentrated, was always the most price-sensitive and churn-prone. Rural customers who switched to Starlink had little reason to return — and the data suggests they haven't.
What the Viasat numbers don't fully capture is the counterfactual: how many potential new subscribers Starlink captured that would otherwise have joined Viasat's base. The 81% decline measures only the customers who left, not the market share that was never contested in the first place.
For SpaceX, the Viasat data is a useful competitive benchmark, but the more consequential growth story is now in segments where subscriber counts aren't publicly reported with the same quarterly granularity — aviation, maritime, direct-to-cell, and government contracts. Whether Viasat can stabilize its business in those higher-margin verticals, even as its consumer base continues to shrink, is the open question heading into the second half of 2026. At 115,000 US fixed broadband subscribers and still declining, the consumer chapter looks close to its final pages.
