Churchill Capital Corp. VI raised $480 million, upsized from $400 million in the IPO, said the person, who asked not to be identified because the information wasn’t public yet. A second special purpose acquisition company, Churchill Capital Corp. VII, raised $1.2 billion after earlier planning to raise $1 billion, the person said.

A representative for Churchill Capital declined to comment.
