Indicators of market inefficiency in sports betting often include oddsmakers providing highly favorable lines relative to a team's true performance, discrepancies between betting odds on different sportsbooks, and significant line movements that do not correlate with new, relevant information. For instance, if a team has recently performed well yet the odds favor their opponent without justification, this could signal an opportunity. Additionally, observing sharp betting action, where large sums are placed on one side of a wager, can suggest that knowledgeable bettors are identifying value that the general public overlooks.
