Several factors can significantly influence the Expected Value (EV) of a betting opportunity, including the accuracy of probability assessments, the odds provided by sportsbooks, and the timing of the bet. Accurate evaluations of team performance, historical data, player injuries, and matchup specifics contribute to a more precise understanding of an event's likely outcomes. Additionally, the odds offered by bookmakers can fluctuate based on market dynamics, public sentiment, and betting volume, affecting the potential returns.
