What Is Closing-Line Value?
Compare your placed price with the market's last price before an event starts.

How we create and check guidesThe short answer
Closing-line value, commonly called CLV, compares the price you placed with the market's last available price before the event began. Getting a better price than the close is called positive CLV.
Simple example
You bet a team at +120. Before the game starts, the broad market moves to +105. Your ticket pays $120 profit for every $100 risked while a late bettor receives only $105. You captured the more valuable price, even if the team ultimately loses.
Why bettors track CLV
Wins and losses are noisy in small samples. CLV asks a different question: did later market information make your earlier price look good? Consistently beating a mature closing market can be evidence that a process finds useful prices.
Moneyline and point CLV
For moneylines, compare implied probabilities rather than simply subtracting American odds. For spreads and totals, track both the number and the price: -2.5 at -110 can be more valuable than -3 at -110 because a three-point result matters.
Important limitations
There is no single universal closing line because sportsbooks update at different times. LineLens uses its last observed pre-start price and labels it as an approximation. Low-limit or thin markets may also close less efficiently than major markets.
