WASHINGTON, Nov. 21, 2025 – After nearly two years of AT&T being its sole tenant, Gigapower has finally onboarded another Internet service provider.

Gigapower, the joint venture between AT&T and BlackRock, announced Wednesday that it had launched a pilot agreement with New York-based provider Flume to deliver managed Wi-Fi and fiber solutions to select apartment buildings and condominiums in Mesa, Arizona.

The deal puts fresh attention on whether Gigapower can fairly be considered an open access network, or a network in which multiple providers are able to offer services with a single network operator. Until Flume, AT&T remained Gigapower’s only tenant. Opening the network up to a single ISP in one market may not be enough to quiet critics.
