Comcast Corporation
Comcast owns cable broadband, Xfinity Mobile, NBCUniversal, Peacock, and Sky.
On the record
Checkpoint: NBCUniversal and Sky spin-off expected to close, plus Q3 2026 broadband loss trend read
The call
Comcast keeps bleeding broadband subscribers to fiber and wireless rivals while wireless growth and a newly profitable Peacock offset the losses for now.
Comcast runs the pipes and wires that bring internet, TV, and phone to tens of millions of American homes. It is hard to replace because it owns the physical cables buried under streets and has legal rights to attach equipment to poles; AT&T, Verizon, T-Mobile, and Starlink are already offering faster internet to Comcast customers, and the company lost 167,000 broadband subscribers in the first half of 2026. The one thing that could change the picture is how fast fiber and wireless internet spread through Comcast's territory; if customer losses jump back above 200,000 per quarter instead of slowing down, the company's income and value could weaken much sooner than currently expected.
Why
01
AI pressure: AI video generation tools (OpenAI Sora, Google Veo) and AI content discovery. AI-made video and AI search could someday cut demand for scripted TV and change how people find shows, not yet visible in Peacock or Studios numbers. Could AI do the core job? Unlikely.
02
Bigger players: AT&T fiber, Verizon/Frontier, T-Mobile fixed wireless, SpaceX Starlink. Comcast lost about 167,000 domestic broadband subscribers in Q2 2026 as fiber and fixed wireless overbuild its footprint. Could a giant copy it? No, they are blocked.
03
What protects it. A physical last-mile network reaching 65 million homes plus franchise and pole-attachment rights that rivals cannot just copy, backed by steady free cash flow.
What would change this call
Q3 2026 domestic broadband losses exceed 200,000 versus Q2's 167,000. Would show fiber and fixed wireless substitution accelerating rather than narrowing.
Verizon/Frontier or AT&T announce expanded fiber buildout inside Comcast's service footprint. Would show the physical last-mile moat is being directly overbuilt in more markets.
Peacock adjusted EBITDA turns negative again in Q3 2026 after its first profitable quarter. Would show the streaming profitability gain was seasonal, not durable.

Questions people ask
- Is Comcast profitable in 2026?
- Yes. Comcast reported Q2 2026 revenue of $29.94B and free cash flow of $4.6B on July 23, 2026, with adjusted EPS of $1.04 beating consensus. Net income fell 68% year over year only because Q2 2025 included a one-time $9.4B Hulu gain.
- Is Comcast losing broadband customers to fiber and 5G?
- Yes, but the pace is slowing. Comcast lost about 167,000 domestic broadband subscribers in Q2 2026, an improvement from 201,000 lost in Q2 2025, as AT&T fiber, Verizon/Frontier, T-Mobile fixed wireless and Starlink take share.
- Will Comcast split up?
- Yes. On June 29, 2026 Comcast announced it will spin off NBCUniversal and Sky, including Peacock, into a separate public company led by Mike Cavanagh, expected to close around mid-2027, while Michael Angelakis leads the remaining connectivity business.
- Is Peacock profitable?
- Peacock posted its first-ever quarterly profit in Q2 2026: adjusted EBITDA of $189M on revenue of $1.9B, up from a $101M loss a year earlier, reaching 48 million paid subscribers, though still smaller than Netflix's roughly 80 million US/Canada households.
- Who is Comcast's biggest competitor?
- Comcast faces Charter Communications in cable, AT&T and Verizon/Frontier (fiber, Frontier deal closed January 2026) and T-Mobile fixed wireless in broadband, and SpaceX Starlink in rural markets, all actively taking broadband share as of mid-2026.
- Could AI replace Comcast's core business?
- No. Comcast's moat is a physical hybrid fiber coax and wireless network reaching about 65 million homes and businesses plus franchise and pole-attachment rights, which AI cannot replicate; Comcast instead uses AI for network self-healing and edge compute, per its March 17, 2026 NVIDIA partnership.
