SoftBank Group on Monday said it had agreed to buy the robotics division of Swiss engineering firm ABB for $5.4 billion, as the Japanese giant looks to bolster its artificial intelligence plays.

The deal, which is subject to regulatory approval globally, means ABB will no longer look to spin off its robotics business as a separately listed company.

“SoftBank’s next frontier is Physical AI. Together with ABB Robotics, we will unite world-class technology and talent under our shared vision to fuse Artificial Super Intelligence and robotics — driving a groundbreaking evolution that will propel humanity forward,” Masayoshi Son, founder of SoftBank, said in a statement.

Artificial Super Intelligence, or ASI, is Son’s idea of AI that is 10,000 times smarter than humans.

Son has looked to position SoftBank at the center of the potential AI boom through investments and acquisitions in different areas of technology. SoftBank owns chip designer Arm, for example, and has a major stake in OpenAI.

SoftBank already has some robot-related investments, including AutoStore Holdings and Agile Robots.

Morten Wierod, who became CEO of ABB in August 2024, has pushed the spin-off of the company’s robotics unit as a strategic move.

ABB said in a statement that the sale “will create immediate value to ABB shareholders.” The company said it will use the proceeds from the transaction “in line with its well-established capital allocation principles.”
