Jan 11 (Reuters) - Electric vehicle startup Lucid Motors is in talks to go public through a merger with a blank-check firm backed by Michael Klein, a veteran Wall Street dealmaker, Bloomberg News reported on Monday, citing people familiar with the matter. Lucid is working with financial advisers on the deal, which could be valued at up to $15 billion, the report said here. Klein’s Churchill Capital Corp IV is the vehicle that is considering the deal with Lucid, Bloomberg said, citing some of the people. Lucid did not immediately respond to Reuters’ request for comment.
