DigitalBridge acquires ArcLight for $1.1 billion, positioning for power generation and AI infrastructure
DigitalBridge Group plans to acquire private power company ArcLight Capital Partners for $1.05 billion, as announced by both parties on Wednesday. ArcLight owns one of the largest private power generation portfolios in the United States, with an installed capacity of 20.8 gigawatts as of June 2025 and a project pipeline of approximately 15 gigawatts. Upon completion of the transaction, ArcLight will operate as an independently managed business under the DigitalBridge platform, subject to several regulatory conditions, including the Hart-Scott-Rodino antitrust waiting period, approvals from the Committee on Foreign Investment in the United States, FERC, and the FCC. Additionally, the transaction is conditioned on the previously announced acquisition of DigitalBridge by a SoftBank affiliate.
DigitalBridge Group—an asset management company that owns data centers and other digital infrastructure—announced on Wednesday that it plans to acquire ArcLight Capital Partners, a private power company, for $1.05 billion. The two parties confirmed the deal in a joint statement, saying the move would create a leading alternative asset manager at the intersection of power, artificial intelligence, and digital infrastructure.
According to a filing DigitalBridge submitted to the U.S. Federal Energy Regulatory Commission (FERC), Boston-based ArcLight owned 20.8 gigawatts of power generation assets as of June 2025. In another filing with PJM Interconnection—a region with active data center development—the company said it had approximately 7 gigawatts of installed capacity within that grid operator's territory as of August 2025. ArcLight says it owns one of the largest private power generation portfolios in the United States and has a project pipeline of about 15 gigawatts.
"This combination will create a leading alternative asset manager at the forefront of the convergence of power, AI, and digital infrastructure, integrating two specialized platforms with more than $150 billion in combined assets under management," the parties said in the statement. DigitalBridge CEO Marc Ganzi said in the press release: "AI is reshaping the global power landscape, accelerating investment in generation, transmission, and behind-the-meter infrastructure."
Upon completion of the transaction, ArcLight will operate as a separately managed business under the DigitalBridge platform. The deal is subject to several closing conditions, including the expiration or early termination of the Hart-Scott-Rodino antitrust waiting period, and approvals from the Committee on Foreign Investment in the United States (CFIUS), FERC, and the Federal Communications Commission (FCC).
Notably, the transaction is also conditioned on the previously announced acquisition of DigitalBridge by an affiliate of SoftBank Group. SoftBank announced on December 29, 2025, that it would acquire DigitalBridge for $4 billion to expand next-generation AI infrastructure.
This acquisition is the second recent transaction between ArcLight and DigitalBridge. In March 2026, ArcLight agreed to acquire InfraBridge's 50% stake in AMPCI Thermal Power, a 5.4-gigawatt joint-venture power portfolio under Invenergy. DigitalBridge owns InfraBridge.
