Charter's Spectrum brand has finished absorbing Cox, with former Cox customers now billed by Spectrum starting Wednesday. The deal, agreed in May 2025, cleared its last regulatory hurdle after the California Public Utilities Commission approved it last month, giving Charter over 35 million customers nationwide.
AT&T filed a lawsuit against Charter on Friday, claiming Spectrum's marketing of its internet as 'fiber-powered' misleads customers who aren't actually getting a full fiber connection. Spectrum's network relies on fiber-optic lines for most of its infrastructure but typically switches to copper coaxial cable for the final stretch into homes, unlike true fiber providers that run fiber directly to the wall jack. The suit was filed in Dallas, a market where both companies compete heavily for broadband customers.
