What is Closing Line Value (CLV)?
CLV measures whether you got better odds than the closing line. It's the single best predictor of long-term betting profitability. Professional bettors focus on CLV, not win rate — because a bettor who consistently beats the closing line will be profitable over thousands of bets, even if individual bets lose.
