(Bloomberg) -- Sheldon Adelson’s Las Vegas Sands Corp. is exploring the sale of its flagship casinos in Las Vegas, according to people familiar with the matter, a move that would mark the mogul’s departure from the gambling mecca. The casino operator is working with an adviser to solicit interest from potential suitors, and may fetch $6 billion or more for its Vegas properties, said the people, who asked to not be identified because the talks are private. The portfolio includes the Sands Expo Convention Center, the Venetian Resort Las Vegas and the Palazzo.
