SoftBank has completed its $4 billion acquisition of DigitalBridge, the digital-infrastructure manager, according to trade coverage over the weekend. DigitalBridge will operate as an independent infrastructure arm anchored by SoftBank, with a mandate to raise outside capital from institutional investors for AI-linked data centers, power projects and related assets.
The structure matters because it lets Masayoshi Son pursue AI infrastructure projects that exceed what SoftBank can support from its own balance sheet. DigitalBridge gives SoftBank a permanent-capital-style vehicle for the picks-and-shovels layer of the AI stack, alongside its stakes in OpenAI and Arm — control over the full stack from chips to concrete.
DigitalBridge CEO Marc Ganzi provided the sober counterweight: cooling data-center valuations, tighter financing and local zoning issues could mean around half of the data-center leases signed in 2024 will never get built. That caveat, from inside the buyer camp, is the near-term demand-side signal to set against the $25 billion portfolio chatter elsewhere in the market. A separate report that DigitalBridge acquired ArcLight Capital Partners is unverified and conflicts with the known corporate structure; it should not be relied on.
