Why SoftBank is betting $4 billion on DigitalBridge as AI infrastructure heats up

SoftBank announced a deal Monday to acquire DigitalBridge for $16 per share, or roughly $4 billion including debt.

The announcement capped weeks of speculation about the Japanese conglomerate's interest in the data-center investment firm.

The move signals SoftBank's aggressive push to consolidate AI infrastructure assets as the industry races to build the computing capacity AI demands.

Shares surged more than 50% in premarket trading as investors placed bets on how this acquisition accelerates the global AI infrastructure buildout.​

DigitalBridge stock spikes ahead of decision

DigitalBridge stock jumped from Friday's close of $13.62 to $20.10 in premarket trading Monday morning, reflecting the market's appetite for digital infrastructure exposure.

The surge coincided with trading volume that reached roughly 10 times the company's daily average, underscoring investor enthusiasm for the consolidation of AI-critical real estate.

Analysts had been cautiously bullish ahead of the deal.

RBC Capital raised its price target to $23 just days before the announcement, citing acquisition potential and exposure to AI-driven data-center demand.

JPMorgan had set a prior target of $18, which suggests SoftBank's $16-per-share offer landed in line with expectations.​

What's notable is how cheaply SoftBank acquired DigitalBridge relative to its asset base.

The company manages roughly $108 billion in digital infrastructure assets, from sprawling hyperscale data centers to regional edge facilities, yet commands only a $2.54 billion equity value at the deal price.

That's a steep discount to publicly traded rivals like Equinix, which trades at a far higher valuation multiple and has a $74.9 billion market capitalization.

For DigitalBridge shareholders, the deal offers a quick exit before the next leg of AI-driven consolidation potentially removes other infrastructure plays from the public markets.​

Why SoftBank wants DigitalBridge

SoftBank's acquisition of DigitalBridge reflects how essential physical assets have become to the company's AI strategy.

The Japanese conglomerate is already the lead investor in Stargate, a $500 billion venture with OpenAI and Oracle aimed at building 10 gigawatts of AI compute capacity across the United States.

DigitalBridge's portfolio, including the hyperscale operators Vantage Data Centers, Switch, AIMS, and AtlasEdge, plus the smaller DataBank edge network, gives SoftBank direct control over prime locations for deploying AI workloads.

More critically, it gives SoftBank control over power and cooling infrastructure, the hardest bottlenecks in scaling AI right now.​

The strategic fit goes beyond square footage.

DigitalBridge has been positioning itself for the AI pivot, partnering with Korean telecom KT Corporation to develop AI-grade data centers in Asia and maintaining a global footprint spanning North America, Europe, and Southeast Asia.

By taking DigitalBridge private, SoftBank eliminates the need for quarterly earnings calls and investor approval before pivoting capital toward Stargate-adjacent projects.

CEO Marc Ganzi built an operator with institutional-grade discipline; SoftBank now owns it outright, allowing faster execution on AI infrastructure expansion without coordination overhead.​

Integration with Stargate unlocks optionality. OpenAI, Oracle, and SoftBank have already announced five new Stargate sites with plans to ramp capacity from 7 gigawatts to 10 gigawatts over the next three years.

DigitalBridge's portfolio of global infrastructure, renewable power agreements at Switch, edge computing nodes across AtlasEdge's European footprint, and hyperscale capacity at Vantage can be directly allocated to Stargate's expansion roadmap.

In effect, SoftBank is acquiring not just assets but velocity in an era where AI compute capacity availability is the strategic constraint, not cost.​​
