Available reporting places the New York Yankees at the top of MLB World Series wins with 27 titles, the highest total among major American professional sports franchises [1].

The St. Louis Cardinals follow with 11 championships, and the Los Angeles Dodgers are listed with nine after their 2025 victory that moved them into a higher ranking [1].

The Boston Red Sox and Athletics appear tied for the next position, with the San Francisco Giants at eight and the Cincinnati Reds and Pittsburgh Pirates each at five [1].

Twenty-five of the thirty MLB teams have secured at least one World Series title, leaving five without any, including the Seattle Mariners who have not yet reached the Fall Classic [1].

Because the details originate from one outlet and carry an explicit flag for needing additional corroboration, the ranking should be treated as preliminary rather than settled [1].
