What is expected value?
Expected value (EV) is the average profit per bet if you placed the same wager thousands of times. The formula: EV = (true win probability × profit if win) − (loss probability × stake). Positive EV means the book is paying you more than the true odds warrant — over time you make money. Negative EV is a losing proposition.
The hard part is finding the true win probability. Sharp books like Pinnacle, or the consensus across many books, are the best proxy. Our boost analyzer does this automatically for any sportsbook boost.
