Why it matters

The strategic read

Moves the AI buildout financing stack closer to the power stack. DigitalBridge is not buying another data-center asset here; it is buying an energy-infrastructure investment manager so hyperscale data-center capital, power generation, transmission, batteries and midstream expertise can be packaged together under SoftBank’s broader AI infrastructure strategy.
