What is closing line value?

Closing line value (CLV) is the difference between the price you bet and the price when the game started. If you bet a team at -105 and it closed at -120, you beat the closing line and had positive CLV.

Why the closing line matters

The closing line is the market's final answer after all the money has come in. It is the most accurate price of the day. If you bet at a better price than the close, you had a better number than the market's best guess, whatever the game then did.

An example

Monday, 11 AM: Bills -2.5 at -105. Kickoff: Bills -3.5 at -110. You beat the close by a point and five cents. Whether the Bills cover or not, you bought low. Do that often enough and the results follow.

Why it is the best early sign

Results take hundreds of bets to mean anything, because good bets lose often. Closing line value shows up in dozens. That is why sportsbooks limit accounts that beat the close consistently: it predicts who they will be paying over time.

Can you beat the close and lose?

Yes, and often. One night proves nothing either way. Over a season, beating the close by a couple of percent on average is where the profit comes from.

What we track

Every pick we post is logged with its price, and the closing price is recorded at game time. The share of picks that beat the close and the average closing line value are on our Results tab, updated after each game, next to the win rate.

How to track your own

  1. Write down the price you got when you bet.
  2. At game time, write down the price the book is showing.
  3. Compare. Better than the close is a plus; worse is a minus. Keep a running average.

Questions

What is a good CLV?

Beating the close more than half the time and averaging a gain of 1% to 3% is strong. Most bettors are negative without knowing it.

Is CLV the same as winning?

No. It is the best early predictor of winning that exists, but any stretch of bets can lose while beating the close.

Why do sportsbooks care about it?

Because a bettor who beats the close is one they expect to pay out to over time, so they limit those accounts.
