SoftBank Group is acquiring digital infrastructure investor DigitalBridge Group for approximately $4 billion, paying $16 per share, a 15% premium. This move aims to bolster SoftBank's investments in artificial intelligence by expanding its digital infrastructure portfolio, which includes data centers, cell towers, and fiber networks. DigitalBridge, managing $108 billion in assets, will continue to operate as a separately managed platform under its current CEO. The deal, valued at $2.9 billion, is expected to close in the second half of next year and is driven by surging demand for AI computing power.
