Closing Line Value Explained

Bet types & conceptsClosing line value

Closing line value (CLV) measures whether you beat the final odds before an event starts. This guide explains it with hypothetical examples only.

Key takeaways
  • Closing line value compares the odds you took with the closing odds just before an event.
  • It is widely seen as the market's most accurate price, so beating it consistently suggests skill rather than luck.
  • No.

What CLV is

The 'closing line' is the odds just before an event begins. CLV compares the price you took with that closing price.

Why it matters

The closing line is widely seen as the market's most accurate price.

Example. If you backed a team at 2.20 and it closed at 1.90, you beat the close — a sign you found value before the market caught up.

A long-term signal

Consistently beating the closing line suggests skill rather than luck, even before results are known. It is a feedback tool, not a guarantee on any single bet.

Using CLV

Sharp bettors track CLV to judge their process. It works alongside line shopping and understanding implied probability.
