SoftBank's acquisition of Ampere Computing faces U.S. government investigation

SoftBank Group's acquisition of semiconductor design company Ampere Computing is facing a potentially protracted investigation by the US government. The US Federal Trade Commission (FTC) has launched an in-depth investigation into the acquisition. SoftBank announced in March 2025 that it would acquire Ampere in an all-cash deal valued at $6.5 billion. This marks another step for the Japanese company in enhancing its artificial intelligence (AI) infrastructure capabilities.
