Comcast (operating as Xfinity) lost 144,000 residential broadband subscribers in Q3 2026, a worse result than the 91,000 losses recorded in the same quarter of 2025 — and well above analyst estimates, which projected losses of 116,800. The residential connectivity segment revenue fell 4.7% year-over-year, totaling $29.3 billion for the quarter. Amid this backdrop, CFO Jason Armstrong called the $30 to $40 per month rates for 1 gigabit plans offered by fiber operators "irrational pricing," arguing that no sustainable business model justifies those prices when the cost of installing fiber to a home is "potentially thousands of dollars."
What makes this story more than a simple earnings report is the revelation that Comcast is planning significant personnel cuts as part of a restructuring of its cable TV, broadband, and wireless businesses. The company ended the quarter with 28.3 million residential broadband subscribers — the highest absolute number in the company's history, but growth is no longer what it once was. The loss of 144,000 subscribers represents a structural shift in the US residential internet market, and Comcast itself acknowledges that the competitive landscape is likely to remain "intense."
What the numbers hide
Behind the staggering loss figure — 144,000 subscribers in a single quarter — lies a technological shift that had been underway for years. DOCSIS 3.1, the protocol Comcast uses to deliver internet via coaxial cable, has fundamental limitations: uploads are throttled to a fraction of download capacity. A 1.2 gigabit Xfinity plan, for instance, offers only 35 Mbps uploads. Fiber competitors, by contrast, offer symmetric 1 gigabit speeds, both upload and download.
This technological gap translates into a structural competitive advantage for fiber: it is not just about price, but about actual performance. Comcast has already removed its data caps and offered five-year price guarantees from $45 per month to retain subscribers, but even so, it cannot stem the bleeding. In Q1 2026, the company had already lost 65,000 subscribers; in Q2, 167,000. Q3 brought the worst single-period result since tracking began in 2022.
Armstrong's strategy: blame the competitors
Comcast's CFO approach was direct and, in a tone of frustration, almost personal. At a Goldman Sachs event in September, Armstrong not only criticized competitors' low prices but also warned about an emerging threat that many analysts were beginning to notice: satellite internet. "Satellite looms out there as a potential threat," Armstrong said. "We're not really seeing it yet, but there's no complacency around it."
The reference was obvious: SpaceX's Starlink, which already has over 9 million global subscribers and has consolidated as a viable alternative in rural and deep suburban markets. For Comcast, which historically operated with little or no competition in many of its coverage areas, the emergence of three simultaneous competitive fronts — fiber, fixed wireless access (FWA), and satellite — represents a radical transformation in market dynamics.
Armstrong also noted that fiber deployment in his service area accelerated from 2-3% per year to 4-5%, nearly doubling the overbuild rate. "Fiber is the long-term competitor," he said, without mincing words. What he did not say explicitly, but the data speaks for itself: in markets where fiber has arrived, Comcast's losses are exponentially larger than in markets where it has not.
What is "rational"?
Armstrong's criticism of competitors raises a nearly philosophical question: what is a "rational" price for an essential service like internet? For Comcast, charging $50 per month for 1 gigabit via HFC is rational; charging $30-40 for symmetric fiber is "despicable." The difference is not just about price — it is about business model.
New fiber operators entered Comcast's markets with aggressive penetration strategies: low initial prices, free installation, flexible contracts. The goal is not to profit in the first few months, but to secure access to the home for eventually raising prices once the customer base stabilizes. It is the same model that cable operators used in the 2000s to gain ground on telecoms — only now the roles have been reversed.
TD Cowen analysts, led by Gregory Williams, classified Armstrong's remarks as "bearish commentary" and predicted that broadband subscriber losses could hit record levels in Q3. Comcast's stock fell from $26 to $25 right after the remarks — a small movement, but symptomatic of investors being concerned not just about the current quarter, but about the structural future of the company's broadband business.
The silent restructuring
While Comcast loses broadband subscribers, what many are calling "the biggest industry shuffle" is happening behind the scenes: the company announced it will split into two companies in mid-2027, separating its media and entertainment assets (NBCUniversal and Sky) from its core broadband, wireless, and cable TV business. Michael Angelakis will return as CEO of the retained segment, which includes broadband, wireless, and Xfinity TV, while the media side will be led by Mike Cavanagh.
The planned personnel cuts will mainly hit the cable TV segment, but broadband is likely to feel the effects too. Comcast is already expanding its use of AI agents for customer service — a way to reduce operating costs even as the customer base shrinks. It is the paradox of a company with the highest number of residential broadband subscribers in the US, but which, paradoxically, has never been closer to losing its dominant position in the sector.
And when fiber finally reaches 20% or more of the residential base served by Comcast in the US, what remains of the argument that "wire wins"? The trend suggests that the natural monopoly that fueled Comcast's wealth for two decades is dissolving under pressures that are not cyclical, but structural. Internet is the new oil — and the pipelines are multiplying.
