What is Closing Line Value (CLV) in sports betting?

Plain-English answer

Closing Line Value, or CLV, measures whether the price you locked on a sports bet beat the market's final price at kickoff. If you bet a -3 spread at -105 and that line closed at -120, you captured +15 cents of CLV. Positive CLV is the single best predictor of long-run profitability because the closing line aggregates every sharp bettor's information. A bettor with consistent positive CLV but a temporary losing streak will outperform a bettor with positive ROI but negative CLV over a full sample. NuroPicks captures the closing price for every published pick within two minutes of kickoff and writes it to an append-only ledger so it cannot be revised. See our public record at nuropicks.com/record.

Tuesday 7:14 PM ET. Chiefs at Bills, NFL Week 11. NuroPicks publishes a pick: Chiefs -3 at -105.

You tail it on DraftKings at -3 -105. Over the next 75 minutes, sharp money pounds the Chiefs. The line moves -3.5 -110, then -3.5 -115. At kickoff, it closes Chiefs -3 at -120 on the reference book.

CLV = closing price minus your price = -120 minus -105 = +15 cents.

You captured 15 cents of edge versus the closing market. Whether the Chiefs cover that night does not change the fact that you bet a number the rest of the market would now pay 15 cents more for. Run that over 500 picks and the math compounds.
