Comcast reported a loss of 144,000 residential broadband customers in the third quarter of 2026, a sharp increase from the 91,000 customers it lost in the same period last year. The company, which is reportedly planning significant job cuts in its cable division, attributed the deepening subscriber losses to aggressive competition from fixed wireless providers and fiber-optic networks.

The latest earnings figures mark a continuation of a difficult trend for the nation's largest cable provider. The 144,000 net loss in residential broadband customers comes as the company faces what it describes as a two-front competitive assault.

Comcast co-CEO Mike Cavanagh addressed the competitive landscape during the company's earnings call today. 'Fixed wireless remains aggressive and continues to take share, while fiber construction remains elevated, with pockets of irrational pricing and promotional activity,' Cavanagh said, characterizing the approach of rivals as below-cost pricing to gain market share.

The erosion of Comcast's broadband base, long its most reliable profit engine, underscores a rapid shift in the US broadband market. For years, Comcast enjoyed a dominant position with limited high-speed alternatives in much of its territory. Now, a combination of 5G-based fixed wireless from mobile carriers and the expansion of fiber networks is giving consumers genuine alternatives.

The company is reportedly preparing to cut jobs within its cable division as it adjusts to the new market reality.

Analysis

Why This Matters

Broadband is an essential service; the competitive dynamics directly affect prices and service quality for tens of millions of households.
Comcast's subscriber losses signal a potential end to the cable monopoly model, which has long faced criticism for high prices.
The planned job cuts foreshadow a wave of restructuring across the legacy telecom and cable industry.

Background

For decades, Comcast built its business on a near-monopoly over high-speed internet in its service areas. This allowed it to wield significant pricing power. The landscape has changed in the last five years, with the rise of 5G fixed-wireless access and aggressive fiber buildouts fundamentally altering the competitive dynamics.

Key Perspectives

Comcast (Mike Cavanagh): Competitors are pricing below cost to buy market share, creating an "irrational" market that compels Comcast to lose customers or erode its own margins. Fixed Wireless and Fiber Rivals: The market is finally seeing long-overdue competition. Pricing is a legitimate strategy to win customers from a dominant incumbent with high margins. Consumer Advocates: Welcome the increased competition. They argue the market is simply correcting, and Comcast’s discomfort indicates that consumers are finally getting a better deal.

What to Watch

The scale and timing of the planned job cuts at Comcast.
Whether the broadband subscriber losses accelerate or plateau in the coming quarters.
Comcast's strategic response: further investment in its own fiber, a pivot to wireless, or deeper bundling with streaming and mobile.
