Underlay

1 min read

A bad or unfavorable bet.

In the context of gambling, particularly in sports betting, the term "underlay" refers to a situation where the odds offered on a bet are considered to be less favorable than the true probability of the outcome occurring. Essentially, it means that the bettor is not getting a fair value for their wager.

For example, if a team has a 50% chance of winning a game, but the odds offered suggest a probability of only 40%, then that bet would be considered an underlay. Bettors typically want to avoid underlays because they represent a poor value proposition, making it less likely for them to achieve a profitable outcome over time.
