Antonyms for the word "most tipped" could include least expected, underrated, unanticipated, underestimated, and unpopular. These terms describe situations where an outcome or result is not seen as likely or probable, but may still occur despite low expectations. For example, a team that is deemed unpopular by analysts may surprise everyone and win a game. Similarly, an underestimated player could outshine their highly touted opponents. It is important to remember that the most tipped option may not always be the most accurate, and that unexpected outcomes are what make sports and other areas of life exciting.
