WASHINGTON, Sept. 24, 2025 – Gigapower, the open access fiber joint venture between AT&T and BlackRock, the world’s largest asset management firm, has completed network construction in six states and is serving “just under 70 communities,” according to Jeff Seidenfaden, Gigapower’s chief revenue officer.
The six states are Florida, New Mexico, Pennsylvania, North Carolina, South Carolina, and Minnesota. Seidenfaden said the venture continues to pursue its goal of reaching 1.5 million fiber locations nationwide. Gigapower has not disclosed how many fiber passings it has completed to date.
Seidenfaden told Fierce Network earlier this month that Gigapower is “currently engaging with multiple ISPs” and expects another provider to begin offering service on the network within 30 days.
