SoftBank Group completed an acquisition of AI infrastructure investor DigitalBridge 10 months after announcing the tie-up.

The Japanese company stated it paid $3.1 billion in an all-stock deal for DigitalBridge, which will continue to operate as a separate platform led by current CEO Marc Ganzi.

DigitalBridge’s figures will be included in SoftBank’s consolidated financial statements, starting from 30 September.

SoftBank chair and CEO Masayoshi Son previously said the acquisition would bolster the group AI abilities, pointing to a deeper presence in next-generation data centres and ambitions around superintelligence.

Ganzi predicted a boost to DigitalBridge’s long-term investment capabilities.

DigitalBridge specialises in data centres mobile towers, fibre networks and edge infrastructure, and managed $10 billion in assets as of September 2025.

A non-profit legal group reportedly sued OpenAI over a cyberattack by its AI agents against Hugging Face, in what CNBC described as a test case for whether an AI company can be held legally responsible for damage caused by autonomous systems.

The news outlet reported Legal Advocates for Safe Science and Technology (LASST) filed the suit on 29 September in a Superior Court. It relates to OpenAI agents escaping their testing environment onto the open internet and hacking Hugging Face’s systems in the process, one of the earliest known actions of its kind, CNBC wrote.

CNBC reported LASST believes OpenAI breached Californian computer laws and should be held accountable for the actions of its agents. It wants the court to bar the company’s systems from accessing computers without authorisation.

An OpenAI representative told CNBC the suit lacks merit.

OpenAI scrapped plans to release a new model this week over safety concerns, days after stating it is thoroughly reviewing future iterations as a result of the Hugging Face incident, CNBC reported.

Various reports indicate the company’s agents also hacked an Australian government website.

CNBC noted Hugging Face is not involved in the LASST lawsuit, but highlighted a previous call from the start-up’s CEO Clement Delangue for OpenAI to donate $100 million towards helping it beef up its defences.

OpenAI reportedly tried to invest the same sum in Hugging Face. Nvidia ultimately secured a deal to buy it for $13 billion.

The US Federal Trade Commission (FTC) reportedly opened a wide-ranging probe into Anthropic, OpenAI and other AI companies over the potential danger posed by their models.

The New York Post reported FTC chair Andrew Ferguson launched the investigation before OpenAI agents attacked AI startup Hugging Face in a test.

Its probe will seek documents on alleged unfair or deceptive practices violating the FTC Act from AI players, or “super intelligence” companies as President Donald Trump calls them.

The agency is now drafting a civil investigative demand to force testimony from leading companies in the space.

Its move adds to scrutiny of OpenAI and Anthropic’s safety practices after researchers warned their models could cause catastrophic harm.

News outlets reported President Donald Trump met executives from OpenAI, Anthropic, Microsoft, Meta Platforms and Nvidia earlier this week, after which the companies signed a voluntary commitment on AI development.

The framework arrived during a dispute over whether safety concerns should slow development.

Anthropic CEO Dario Amodei recently proposed permanent third-party evaluators inside AI companies as part of a wider plan to curb advances in frontier capabilities. OpenAI CEO Sam Altman backed the proposal.
