The idea
By kickoff, a market like Pinnacle's has absorbed every bet, injury report and line-up. Its closing odds are the most informed price available. If you consistently got odds that were better than that closing price, you were ahead of the information — and that tends to show up as profit over time.
How to calculate it
CLV = (odds you took ÷ closing odds) − 1. Take 2.10 on a team that closes at 1.95 and CLV = 2.10 ÷ 1.95 − 1 = +7.7%. Take 1.90 on a side that closes at 2.00 and CLV = −5%.
The closing odds still contain the bookmaker's margin, so a fairer comparison removes it first. Sharp Bets does that: it fetches Pinnacle's closing price, strips out the margin, and measures your price against the fair closing odds.
Why it beats looking at profit
Profit is noisy. A bettor with a real 5% edge can be down after 200 bets and a bettor with none can be up. CLV strips out most of that luck, because it's measured on every bet at the moment of the bet rather than on who happened to win.
That's why it's the fastest honest test of whether a method works, and why our leaderboard ranks CLV rather than profit.
What it can't tell you
CLV needs a decent sample — a few dozen bets at least — before the average means anything; My Bets shows a 95% range so you can see how sure to be. Thin markets, where the closing line itself is weak, give less reliable readings. And positive CLV isn't a guarantee of profit, only good evidence that the process is sound.
Measuring it with Sharp Bets
Every pick sent to the channel is logged with a timestamp, and the bot captures the closing line minutes before kickoff. The verified feed shows the result across all picks. On My Bets, bets logged with one click get their closing odds filled in automatically, so your own CLV builds up without any typing.
