Comcast and Charter both continue to lose broadband customers.
They’re losing these lucrative customers to an unexpected alternative.
There’s still plenty of this customer migration left to suffer, too.
The fact that streaming video is chipping away at cable television's customer base isn't anything new. That's been the case since 2013. But cable providers were able to count on their broadband internet business to offset this attrition.
Now, however, it seems even high-speed internet is no longer a defensible business. Comcast's (NASDAQ: CMCSA) Xfinity lost another 65,000 high-speed internet subscribers last quarter, while Charter Communications' (NASDAQ: CHTR) Spectrum shed 117,000 residential broadband customers in addition to a small handful of business customers. In both cases, this attrition extends what have become well-developed trends, too. Each company's internet customer count peaked in 2023, and each has since suffered losses in excess of 1 million subscribers.

But if streaming requires a high-speed connection, where are all these broadband customers going?As it turns out, there's a relatively new option that's getting some serious traction.
The top threat to the cable industry's high-speed internet business is no longer a rival cable name. It's wireless telecom names T-Mobile US (NASDAQ: TMUS) and Verizon Communications (NYSE: VZ). Leveraging their 5G mobile broadband networks' high-speed capabilities, consumers can now use this connectivity option -- called fixed wireless access, or FWA -- within their homes just as they would a traditional broadband service.
And they're using this option a lot! The graphic below tells the tale. T-Mobile and Verizon now serve a total of 15.5 million FWA customers after launching these services just a few years ago. It's no coincidence that Comcast's and Charter's high-speed internet customer base began shrinking around that same time.
Spectrum and Xfinity are still the nation's two biggest broadband internet service providers, for the record, and their high-speed internet operations are still important cash cows for both. Internet service accounts for roughly 20% of Comcast's revenue and roughly 40% of Charter's.
That's the problem for both outfits, however -- there's still a wide swath of business to lose to competition that's competitive in price and not necessarily limited by a lack of lines extending all the way to peoples' homes.
This evolution is, of course, a solid opportunity for Verizon and T-Mobile. But it's an even bigger risk for Charter and Comcast, both of which saw earnings before interest, taxes, depreciation, and amortization (EBITDA) tumble last quarter. Weak performances from their high-speed internet businesses were a key contributor to these declines.
Shareholders of either provider can't afford to ignore the fact that this customer migration could continue at this pace for a long, long time.

Four leading AI models discuss this article
"The market is overestimating the long-term viability of FWA as a replacement for high-capacity cable broadband, creating a valuation floor for incumbents as they transition to mobile-converged service bundles."
The narrative that FWA is an existential threat to cable broadband is becoming stale, yet it remains the primary driver of current multiple compression for CMCSA and CHTR. While T-Mobile and Verizon have successfully captured the low-end, price-sensitive segment, they face inherent capacity constraints in their 5G mid-band spectrum. As FWA networks densify, throughput degradation will likely force these telcos to throttle speeds or raise prices, narrowing the value proposition gap. Comcast and Charter possess a structural advantage in latency and symmetrical bandwidth via fiber-deep upgrades (DOCSIS 4.0). The current market valuation—pricing these as terminal-decline assets—ignores their potential to pivot toward high-margin mobile convergence and enterprise services.
If FWA capacity constraints are mitigated by future spectrum auctions or 6G advancements, the 'last mile' cost advantage of cable infrastructure could be permanently neutralized by the lower operational overhead of wireless networks.
"Charter's outsized broadband revenue reliance (40%) amplifies EBITDA and deleveraging risks from ongoing FWA-driven subscriber losses."
Charter (CHTR) is more exposed than Comcast (CMCSA), with residential broadband generating ~40% of revenue versus 20%, making its 117,000 Q1 subscriber loss (versus CMCSA's 65,000) a direct hit to EBITDA already in decline. T-Mobile (TMUS) and Verizon (VZ)'s rapid 15.5 million FWA customer ramp-up underscores accelerating share erosion since 2023 peaks, when both lost over 1 million broadband subs combined. This isn't just low-end churn; FWA's wire-free appeal bypasses last-mile costs, pressuring pricing power in a duopoly long complacent on bundles. CHTR's deleveraging hinges on broadband cash flow—further losses risk credit metrics and buybacks.
FWA growth will likely plateau as TMUS/VZ networks strain under surging demand (median speeds already dipping per recent FCC data), while CHTR/CMCSA's DOCSIS 3.1 upgrades and fiber overbuilds retain high-ARPU, reliability-focused customers in dense markets.
"Charter's 40% broadband revenue exposure to a competitor with zero infrastructure capex burden is structurally dangerous, but the real risk hinges on whether churn accelerates beyond current ~100-150k/quarter pace—a threshold the article never quantifies."
The article frames FWA as an existential threat, but conflates correlation with causation. Yes, CMCSA lost 65k and CHTR lost 117k internet subs last quarter—material but not catastrophic given their scale. The real issue: FWA penetration is still ~4% of U.S. broadband (15.5M of ~380M+ lines). More concerning is the article's silence on FWA's actual limitations—latency, capacity constraints during peak hours, weather sensitivity—which make it a viable *secondary* option, not a wholesale replacement. Charter's 40% revenue exposure to broadband IS a structural risk, but the migration pace matters enormously. If churn stabilizes at 100-150k/quarter, CHTR's EBITDA decline is manageable. If it accelerates to 250k+, that's a different story. The article doesn't distinguish between these scenarios.
FWA adoption could plateau quickly once T-Mobile and Verizon exhaust early adopters and hit network congestion limits, while cable's fiber overlay investments (which the article ignores) may actually improve competitive positioning and pricing power in core markets.
"FWA adoption, if faster and more durable than anticipated, threatens CMCSA/CHTR's core broadband cash flow and could justify multiple contraction unless pricing power and monetization of higher-speed tiers offset the pressure."
The article frames fixed wireless access (FWA) as a secular threat to CMCSA and CHTR’s broadband franchises, implying a long-run cash-flow erosion. Yet several blind spots matter: broadband remains a meaningful-margin business (roughly 20% of Comcast revenue and 40% of Charter), aided by bundles that boost retention. FWA penetration is real but still far from universal; coverage, data caps, and price sensitivity will slow its spread. EBITDA weakness may reflect a near-term capex cycle rather than a permanent shift. If incumbents accelerate fiber upgrades and monetize higher-speed tiers and business services, the downside risk to cash flows could be more muted than the article suggests.
Bear counter: If FWA adoption accelerates beyond expectations, supported by dense markets and favorable pricing, traditional broadband cash flows could compress faster than feared, making the CMCSA/CHTR downside sharper than the article implies.
"FWA-induced price wars will destroy cable EBITDA margins well before network capacity constraints become a material competitive bottleneck."
Claude, you’re underestimating the churn velocity. While 4% market penetration seems low, churn is non-linear; once FWA hits a neighborhood, it triggers a price war that forces cable to sacrifice margins to retain customers. This isn't just about capacity limits; it’s about the erosion of the 'triple-play' bundle's pricing power. If CMCSA and CHTR move to aggressive, low-margin promotional pricing to stop the bleeding, their EBITDA margins will collapse long before the network capacity threshold is reached.
"FWA-induced congestion on telco networks indirectly strengthens cable's low-capex MVNO mobile businesses, offsetting broadband risks."
General: Everyone flags FWA capacity limits hurting telcos, but misses the second-order win for cable—TMUS/VZ network strain from FWA directly degrades their mobile service quality, which Comcast/Charter MVNOs (Xfinity/Spectrum Mobile) free-ride on without capex. This boosts cable's bundled wireless retention and margins as broadband churn slows, turning FWA into an unwitting ally for hybrid models.
"Cable's MVNO advantage from telco network strain is theoretical without evidence of accelerating wireless adoption or margin expansion."
Grok's MVNO arbitrage angle is clever but unproven at scale. Xfinity Mobile and Spectrum Mobile have languished for years—they're not suddenly capturing share because T-Mobile's network degrades. Cable's wireless margins remain thin, and FWA churn won't reverse without a compelling wireless product, not just network spillover. The bundle retention thesis needs evidence: are we seeing CHTR/CMCSA wireless net adds accelerate? If not, this is speculation dressed as second-order thinking.
"MVNO upside is not a durable, margin-boosting shield against broadband churn from FWA."
Responding to Grok: the MVNO arbitrage angle is clever, but I doubt it scales meaningfully. Xfinity/Spectrum Mobile has lagged for years, and wholesale economics, customer acquisition costs, and device subsidies cap upside. Even if CMCSA/CHTR gain some wireless lift, it’s not a reliable, margin-boosting footer to broadband churn; the core risk remains erosion of broadband ARPU from FWA-driven churn, with any mobile upside being probabilistic, not structural.
The panelists generally agree that Fixed Wireless Access (FWA) poses a significant threat to cable broadband providers like Comcast (CMCSA) and Charter (CHTR), with potential impacts on their EBITDA margins and broadband cash flows. However, they differ on the timeline and severity of these impacts, with some arguing that FWA's limitations and cable's structural advantages could mitigate the threat in the near term.
