Lock [Meaning] - MasterTerms.com

Lock

A lock in gambling refers to a bet that is considered a guaranteed win.

A lock is a term often used to describe a situation where the outcome of a game or event seems so certain that bettors believe their wager is practically risk-free. While there are no true guarantees in gambling, a lock typically implies high confidence based on past performance, statistics, or a significant mismatch between competitors. However, it is important to remember that even the most confident bets can still lose due to the unpredictable nature of sports and gambling.

Lock Example

For example, if a top-ranked team is playing against a lower-tier team with poor performance, some bettors may consider the bet on the top-ranked team a “lock.” However, upsets can still happen.
