Every match has an opening line — the first price a sharp bookmaker publishes, often days before kick-off — and a closing line, the last price available before the game starts. Between those two moments, money and information flow into the market, and prices move.
We asked a simple question: when the favourite's price gets shorter between open and close, does the favourite actually win more often?
To answer it we took six full seasons (2020-21 to 2025-26) of Pinnacle opening and closing prices across eight European leagues — Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Eredivisie, Primeira Liga and Segunda División. For each of the 15,727 matches we identified the favourite (the lowest price on the 1X2 market at open) and checked what the price did by kick-off, and what the match did after it.
| Favourite's price by close | Matches | Won | ROI if backed at open |
|---|---|---|---|
| Shortened | 7,211 | 55.4% | +3.5% |
| Drifted | 7,855 | 50.0% | −6.7% |
| Unchanged | 661 | 63.1% | +2.6% |
The market's late movement carries real information. Favourites whose price shortened won five and a half percentage points more often than those whose price drifted — across thousands of matches and six different seasons.
It gets sharper when you look at the size of the move:
| How much the price shortened | Matches | Won | ROI at open |
|---|---|---|---|
| 0–2% | 1,801 | 57.0% | −1.1% |
| 2–5% | 2,580 | 56.6% | +1.6% |
| More than 5% | 2,830 | 53.5% | +8.2% |
Backing heavily-steamed favourites at their opening price would have returned +8.2% — positive in five of the six seasons.
Before you open a betting account: you cannot trade this. The table is sorted on information that only exists after the move has happened. At the moment the opening price is available, nobody knows which favourites will steam. By the time you do know, the price you needed is gone — backing the same steamed favourites at the close returned −1.7%, roughly the bookmaker's margin.
The entire +3.5% edge lived in the price difference between open and close. The information was real; the opportunity to act on it was not, unless you could predict the move in advance. We tried that too, with a model trained on team strength and form: the direction of the move is genuinely predictable (it held in four out of four out-of-sample seasons), but the value it captures is smaller than the margin you pay. Close, but no profit.
This is, in our view, the cleanest evidence you will find that the closing line is smarter than the opening line — and by extension, smarter than almost everyone betting into it. The market does not move randomly; it moves toward the truth.
That is precisely why Closing Line Value is the metric at the centre of everything TipsAudit publishes. If a bettor — or a tipster — consistently takes prices that turn out better than the close, they are systematically getting ahead of information before the market prices it in. That skill shows up long before profit does, and unlike a hot streak of winners, it cannot be faked by luck or survivorship.
So when you evaluate anyone's record, including ours, ask one question first: did they beat the close? A flashy win rate answers nothing — favourites that won 55.4% of the time still lost money for anyone who took the closing price. The number that separates signal from noise is CLV, measured on every pick, published before kick-off, losers included.
That is what our track record shows, and that is the standard we think every betting service should be held to.
