Closing Line Value (CLV)

Quick Definition

The comparison between the odds you bet at versus the final odds available right before the event starts.

In-Depth Explanation

Closing Line Value (CLV) is the gold standard metric used by professional bettors to measure predictive skill. The closing line is generally the most mathematically accurate probability model of an outcome. Consistently beating the closing line indicates a long-term mathematical edge over the market.

Real-World Example in Practice

You bet on Arsenal on Tuesday at odds of 2.20. By kickoff on Saturday, sharp money drives the odds down to 1.85. You beat the closing line significantly.
