The move could be seen as a vote of confidence for Intel, which has been playing catch-up in an industry that has chased the artificial intelligence boom.

Intel shares jumped after SoftBank said it would put $2 billion into the struggling chipmaker amid reports the U.S. government is considering a stake.

A $2 billion investment represents a roughly 2% stake, ranking SoftBank the fifth-largest shareholder of Intel, while a reported 10% stake by the U.S. would be worth about $10.4 billion as of Monday’s share price.
