What CLV is and why it matters more than yield
The metric that separates skill from luck, explained plainly.
The idea in one sentence
CLV measures whether you got a better price than the market before the match started. It does not measure whether you were right.
Why that is the part that matters
Betting markets move. Odds that open at 2.10 may close at 1.90 because informed money came in, a line-up was confirmed, or somebody saw something others did not. The closing price is, in practice, the best available estimate of what is about to happen: it is the price with all the information on the table.
If you took 2.10 and the market closed at 1.90, you took a price that later proved too generous. You found the mistake before anyone else. Whether that particular match landed is largely chance; systematically finding the mispricing is not.
How it is calculated
CLV = (odds taken / closing odds − 1) × 100
With odds of 2.10 and a close of 1.90: (2.10 / 1.90 − 1) × 100 = +10.5 %. Taking 1.80 on a market that closes at 1.90 gives −5.3 %: you paid more than the final price.
Yield and CLV do not measure the same thing
Yield measures how much you won. CLV measures whether you deserved to. Yield needs hundreds of bets to separate judgement from a hot streak, because it depends on results. CLV does not depend on the result, so it says something far sooner.
- Positive CLV, positive yield: wins and deserves to. This is the target.
- Positive CLV, negative yield: betting well, running badly. Usually a matter of time, and the most commonly underrated profile.
- Negative CLV, positive yield: making money at worse prices than the market. That is luck, and luck runs out. The most dangerous profile to follow, because the numbers look great right up until they stop.
- Negative CLV, negative yield: losing, with no reason to expect otherwise.
Why almost nobody publishes it
Two reasons, and the second is the interesting one. The technical one: calculating CLV requires storing the exact odds at the moment the pick was published and comparing them with the closing ones. Anyone logging bets by hand does not have that, and it cannot be reconstructed after the fact.
The less comfortable one: CLV exposes those who win on luck. A channel with a great yield and persistently negative CLV is showing, without meaning to, that its good numbers will not last.
How we calculate it here
When a tipster publishes a pick, the odds are sealed against the market that very second — they are never typed by hand. When the pick is settled, the price that same market had just before kick-off is retrieved and the two are compared. Our CLV is not a claim: it comes from two figures nobody could touch.
If a pick has no closing odds available it simply does not counttowards CLV, rather than counting as a zero. A false zero pollutes everyone’s average.
Frequently asked questions about CLV
What is CLV in sports betting?
CLV (Closing Line Value) is the difference between the odds you took and the odds that same market had just before kick-off. Take 2.10 on something that closes at 1.90 and your CLV is positive: you got a better price than the final market.
How is CLV calculated?
Divide the odds you took by the closing odds, subtract one and multiply by a hundred. With odds of 2.10 and a close of 1.90: (2.10 / 1.90 − 1) × 100 = +10.5 %. A negative figure means you bet at a worse price than the final one.
Why does CLV matter more than yield?
Because it needs far less sample to mean something. Yield takes hundreds of bets to tell skill from luck, since it depends on whether the bets landed. CLV does not depend on the result: it measures whether you spotted the wrong price before the market did. A tipster with sustained positive CLV will win in the end even through a bad run; one with negative CLV and positive yield is almost always living on luck.
What counts as good CLV?
Average CLV that is positive at all, even 1 % or 2 %, already means you are beating the market, and holding it over time is very hard. What matters is not the number on a given day but the sustained sign: consistently positive is what marks a bettor with a real edge.
Why do almost no tipsters publish their CLV?
Two reasons. First, it requires storing the exact odds at the moment of publishing and comparing them with the closing ones, and whoever logs picks by hand does not have that. Second, and less comfortable: CLV exposes those who win on luck, and not everybody wants that number on the table.
Can you have positive yield and negative CLV?
Yes, and it is the most dangerous combination for anyone following that tipster. It means they have made money betting systematically at worse prices than the final market: they got lucky. Given enough bets that luck runs out and the yield follows. The reverse — positive CLV with yield still negative — is usually a good tipster going through a bad run.
