For more than a decade, Comcast and Charter operated broadband internet businesses that were monopolies in everything but name. When a company passes a cable past 100 homes and 53 of those homes buy internet service from them — representing nearly 70% of every actual internet-buying household — that is not a competitive market. That is captive demand. Customers stayed not because the product was superior, but because there was no alternative.
That era is over. It is not ending gradually. It is ending structurally, simultaneously, and permanently across multiple dimensions at once.
The competitive as--ult is coming from every direction. Fiber providers — led by AT&T, which is building 5 million new fiber locations every year through the end of the decade, and Verizon, which acquired Frontier to assemble a 30-million-location national fiber network — are overbuilding cable's footprint at an accelerating pace. Fiber now passes more than 60% of US homes. Where fiber arrives, cable loses approximately one-third of its subscribers — not over time, but immediately and durably. Fiber customers don't come back. Fixed wireless from T-Mobile and Verizon has already attracted 16 million subscribers nationally and capacity is still expanding. Starlink is beginning to address suburban markets at the margin. Charter's CEO described the competitive environment in plain language: it is "not letting up."
The businesses in secular decline are the core businesses. Broadband — the segment representing more than half of both companies' enterprise value — is losing subscribers every quarter with no visible floor. Penetration has fallen from 53% toward 47% and the structural math, applied to AT&T's declared buildout trajectory, points to 38-42% by 2030. Video is losing 3,500 customers per day and will continue doing so until the subscriber base reaches a small residual of customers with no alternatives. Wireline voice is effectively already gone. These are not cyclical downturns. They are one-way technology and market transitions.
The responses available to management make things worse, not better. To slow broadband subscriber losses, Comcast cut prices and locked customers into five-year rate agreements — surrendering pricing power permanently. Charter chose the opposite: protect ARPU, absorb the subscriber losses. Neither path leads to stability. Both companies are investing billions in network upgrades that are defensive in nature — spending capital to stay competitive, not to grow. The wireless businesses are real but structurally parasitic on the broadband base they depend on. If the base shrinks, the wireless ceiling shrinks with it.
The hard reality for the coming years is that two of America's largest companies face simultaneous volume and price pressure in their most important businesses, rising capital requirements to remain competitive, and a competitive landscape that is accelerating rather than stabilizing. The monopoly that sustained their economics for a decade has been replaced by genuine, well-funded, structurally superior competition. What took a decade to build is unwinding in years. There is no technology upgrade, no acquisition, and no promotional campaign that reverses a fiber buildout already written into AT&T's capital plan through 2030.
The ice is melting. The question is only how fast.
More layoffs are coming this summer, and will continue to come as long as they bleed customers.
