SoftBank has moved decisively deeper into the physical foundations of artificial intelligence, signaling a strategic pivot that goes far beyond funding software startups or backing headline-grabbing chipmakers. The Japanese investment group will acquire data center operator DigitalBridge for $4 billion, highlighting how control of compute, power, and connectivity defines AI competition.
The agreement, which values DigitalBridge at $16 per share, represents a premium of roughly 15 percent over its late-December closing price and triggered a sharp rally in the company’s stock. Market enthusiasm had already been building after reports surfaced that a transaction was in the works, sending shares significantly higher even before the deal was confirmed. For SoftBank, however, the price reflects more than near-term market dynamics. It signals conviction that infrastructure, not algorithms, will ultimately determine who can scale AI at a global level.
As artificial intelligence systems grow more complex and resource-intensive, the constraints are increasingly physical. Training and running large models now depends less on software breakthroughs and more on access to vast data centers, reliable electricity, cooling systems, and high-capacity fiber networks. In that environment, firms that own and operate infrastructure occupy a powerful position in the value chain. DigitalBridge, with approximately $108 billion in assets under management and investments spanning data centers, towers, and fiber networks, offers SoftBank immediate scale in precisely those areas.
SoftBank founder Masayoshi Son framed the acquisition in stark terms, emphasizing the growing demand for compute, connectivity, and power as AI reshapes industries worldwide. The language reflects a broader shift in thinking across the tech sector: AI leadership is no longer only about owning the smartest models, but about securing the resources that allow those models to run continuously and at scale.
Multibillion-Dollar Stake in NVIDIA
The timing of the deal is notable. Earlier this year, SoftBank exited its entire multibillion-dollar stake in NVIDIA, a move that surprised markets given the chipmaker’s central role in AI. The sale freed up capital and hinted at a reassessment of where lasting strategic advantage lies. Rather than betting solely on semiconductor champions, SoftBank is now positioning itself to own the environments in which those chips are deployed. That represents a shift from being a financial backer of winners to becoming an operator of critical systems.
DigitalBridge leadership has described the AI infrastructure buildout as one of the defining investment opportunities of the generation. That assessment is supported by the pace of construction worldwide. Hyperscale data centers capable of supporting AI workloads are being planned and built at unprecedented speed, even as concerns grow over energy availability, land use, and regulatory oversight. Governments and utilities are grappling with how to accommodate soaring electricity demand driven by AI, cloud computing, electrification, and reshoring of manufacturing.
The deal also highlights intensifying competition for physical capacity. Major technology companies are locking in long-term power contracts, investing in renewable generation, and designing bespoke facilities to support AI operations. Yet supply remains finite, and building new infrastructure takes years. By acquiring DigitalBridge, SoftBank gains access not only to assets but to relationships with global cloud providers, telecom operators, and enterprise customers already embedded in these networks.
Regulatory review remains an open question. Given the strategic importance of data centers and digital infrastructure, authorities in multiple jurisdictions are likely to scrutinize the transaction. The outcome will be watched closely by rivals and investors alike, as it may signal whether further consolidation in the infrastructure sector is feasible or politically acceptable.
More broadly, the acquisition reflects a maturation of the AI market. The early phase, dominated by experimentation and venture funding, is giving way to an era defined by scale, efficiency, and resilience. In that context, the unglamorous business of building and operating infrastructure becomes a competitive moat. SoftBank’s move suggests it believes the long-term value in AI will accrue not only to those who design models, but to those who keep the lights on and the servers running.
