The U.S. Federal Trade Commission is looking into SoftBank Group Corp's acquisition of semiconductor designer Ampere Computing for $6.5 billion. The FTC's request for more information indicates a potential prolonged government review for the deal. SoftBank's announcement of the purchase in March aligns with its strategy to bolster investments in AI infrastructure. The reasoning behind the FTC's inquiry remains undisclosed. SoftBank has been actively investing in the U.S. tech sector, with engagements such as leading the financing for the $500 billion Stargate data centre project and committing $32 billion to ChatGPT-maker OpenAI.
