SoftBank said it would seek to list Arm, a British chip designer that it bought in 2016, on the stockmarket, after a proposed sale of the business to Nvidia collapsed. Valued at as much as $60bn, the deal would have been the biggest ever in the semiconductor industry, but it ran into regulatory hurdles from the outset when antitrust concerns were raised in America, Britain and the EU. Companies that use Arm’s chip designs, including Microsoft and Qualcomm, had argued the acquisition would give too much market power to Nvidia, which is based in California.
