Masayoshi Son's AI ambitions are reportedly outgrowing SoftBank's own balance sheet, according to the Financial Times (FT, October 4). DigitalBridge CEO Marc Ganzi said his data centre investment group will become SoftBank's "third-party infrastructure arm" following a reported $4 billion takeover, as SoftBank seeks external capital and partners to fund its expansive AI infrastructure bets.
This development is significant because it signals a shift in how major tech conglomerates are financing AI infrastructure buildouts — relying on specialized data-center investment vehicles rather than purely internal balance sheets. SoftBank, led by Son, has made aggressive AI-related investments (including in chips, robotics, and compute), and this arrangement with DigitalBridge suggests the capital requirements have grown large enough to require external structuring.
This story is worth tracking for its implications on AI infrastructure financing models, SoftBank's broader investment strategy, and the role of data-center-focused investment groups like DigitalBridge in the AI buildout.
