Sonder Holdings Inc. is in talks to merge with blank-check company Gores Metropoulos II, Inc. (NasdaqCM:GMII), according to people familiar with the matter. A transaction between Sonder and the Gores special purpose acquisition company, or SPAC, is set to value the combined entity at more than $2.5 billion, said one of the people, who asked not to be identified because the matter is private. Terms haven't been finalized and talks could still fall apart.

Representatives for Sonder and Gores declined to comment.
