Comcast's Q2: How this quarter was different
Comcast's broadband subscriber losses improved year over year for the second consecutive quarter. Management credited simplified pricing, stronger bundles and improving customer satisfaction. Mobilewalla's switching data points to the same conclusion from a different perspective: Xfinity isn't growing yet, but it has largely stopped losing ground.
| Metric | Q2 Snapshot |
|---|---|
| Market Share Index (May 1 = 100) | 99.8 |
| Blended Win/Loss Ratio Index (May 1 = 100) | 108 |
| Win/Loss Ratio vs Verizon 5G Home Internet | 1.01 (up from 0.87) |
What Management Said Vs. What Mobilewalla Data Shows
| Earnings Call | Mobilewalla Data |
|---|
| "Softer gross additions drove the quarter." | Market Share Index declined to 96.9 while Comcast remained flat. |
| "Competitive intensity should ease over time." | Fixed wireless pressure is already moderating, but regional fiber remains elevated. |
| "Mobile continues to be a key growth driver." | Spectrum Mobile reached 20% penetration, outperforming Comcast. |
Xfinity Held Its Ground
Across the 96 DMAs tracked by Mobilewalla, Xfinity's Market Share Index finished the quarter at 99.8, essentially unchanged from early May. Performance varied across markets. Areas such as Dothan, Tampa–St. Petersburg–Sarasota and Fort Wayne posted some of the strongest gains, while other markets saw modest declines.
Taken together, however, the national picture was one of stability, which is a notable shift for an industry that has spent several years steadily losing broadband share.

Mobilewalla's data shows Xfinity's Blended Win/Loss Ratio Index improving steadily into July, finishing the quarter around 8% above where it began. That late-quarter improvement closely mirrors Comcast's own commentary around simplified pricing, expanded mobile bundling and higher customer satisfaction.
Rather than slowing customer losses, Xfinity appears to be winning back a larger share of customers who are actively switching providers.

The most significant improvement came against Verizon 5G Home Internet. Xfinity's win/loss ratio improved from 0.87 in early May to 1.01 by late July, effectively reaching parity. For every customer switching to Verizon's fixed wireless service, Comcast was winning roughly one back.
Performance against T-Mobile Home Internet followed a similar pattern, improving after a softer period in June. These trends align with broader industry research suggesting that the rapid growth of fixed wireless is beginning to moderate as the market matures.
Not every competitive battle is becoming easier. The strongest gains came against CenturyLink, where Xfinity's win/loss ratio more than doubled during the quarter, highlighting cable's advantage over legacy DSL networks.
The picture was more mixed against AT&T Home Internet, Xfinity's largest competitive matchup, while regional fiber providers such as Frontier and Brightspeed continued to apply sustained pressure.
Fixed wireless may be becoming less disruptive, but fiber remains the industry's most formidable long-term competitor.

A flat Market Share Index combined with an improving win/loss ratio suggests Comcast is becoming more competitive in markets where customers are actively choosing between providers.
Improving performance against Verizon and T-Mobile supports the broader industry view that fixed wireless growth is beginning to slow after several years of rapid expansion.
Regional fiber providers and AT&T continue to represent Comcast's toughest competitive battlegrounds, even as broader market conditions become more favourable.
Mobilewalla data suggests this was one of Comcast's strongest broadband quarters in recent years. Market share remained stable, switching momentum improved, and pressure from fixed wireless appears to be easing. The next test is whether Comcast can convert that stabilization into sustained subscriber growth while continuing to defend against expanding fibre networks.
