# Why do odds change before a match? *For anyone who looked at a price on Friday, looked again on Wednesday and found a different number. A plain guide, with this week's Champions League prices as the worked examples.* Features · Published 07:02 CET, 4 Nov 2026 · Match News (https://matchnews.news/features/why-odds-change-before-a-match/) By Features desk · Reviewed by Fredrik Jurek Odds change before a match because a price is not a fixed fact about the game. It is a market's view of how likely each result is, and that view changes whenever new information arrives. The main sources of new information are team news (an injury, a suspension, a line-up), results (the form a team showed at the weekend), and money (more people backing one side than the other, which makes the bookmaker shorten that side's price to keep its book balanced). The clock matters too: the closer a match comes, the more is known, so the last hours before kick-off are when prices move most. That is the whole answer in one paragraph. The rest of this page answers the questions people ask next, using real prices from this site this week. ## What does a price actually represent? A decimal price, the format on this site, shows what you get back for each unit staked, including the stake: 2.00 means 2 back for each 1 risked. Hidden inside every price is a chance, which you find by dividing 1 by the price: 2.00 is 50%, 4.00 is 25%, 1.25 is 80%. That number is called the implied probability, because nobody announces it; it is what the price implies about how likely the market thinks the result is. When a price moves, the useful thing to track is that chance, in percentage points, not the raw decimal, because a move of 0.10 means a lot at 1.50 and very little at 5.00. ## Reason one: team news Take Liverpool's price to win at Fenerbahçe on Wednesday evening. BettingBeast's feed, which this site reads at least once an hour, had Liverpool at 1.62 at 13:54 CET on Friday, which implies a chance of about 62%. On Tuesday Liverpool announced that Ryan Gravenberch, their midfielder, had a fractured heel and would not travel. By 23:23 CET on Tuesday the price was 1.54, about 65%, and at 06:23 CET on Wednesday it was 1.49, about 67%. Notice the direction. A star player went missing and the price got shorter, not longer. That tells you two things about how team news works. First, the market had already been shortening Liverpool all week, from 1.62 to 1.56 by Tuesday morning, before the injury was public, so the injury arrived into a move that was already under way. Second, team news on both sides counts: Fenerbahçe are without Aké and Asensio and have just changed their coach, and the market weighed that too. A single piece of news rarely moves a price on its own; it moves the price relative to everything else already known. A clearer case is Napoli's price to win at Porto on the same night. On Friday it was 3.18, about a 31% chance. By Wednesday morning it was 4.15, about 24%, a fall of seven percentage points. UEFA's team-news page for the match lists seven Napoli players out, including Di Lorenzo, Lobotka and Neres, with De Bruyne and Højlund doubtful. Porto's price went the other way, from 2.25 to 2.00, which is a rise from about 44% to about 50%. When one side's list of absentees grows and the other's does not, the price follows. ## Reason two: results Real Madrid's price to win at AEK Athens was 1.32 at 15:23 CET on Sunday, an hour before Madrid kicked off at Racing Santander. By 19:23 CET, with Madrid having won 3-0, it was 1.29. Napoli's price to win at Porto was 3.20 at 22:23 CET on Sunday, around the final whistle at Juventus, where Napoli lost 2-0, and 3.51 an hour later at 23:20 CET. Results move prices because they are the freshest evidence of how good a team is right now, and because they change the context: a team that has just lost two in a row carries doubt into its next game, and the market prices that doubt. Our Markets piece on the Madrid move is linked below. ## Reason three: money A bookmaker sets a price, then takes bets. If far more money arrives on one side than the other, the bookmaker shortens that side's price and lengthens the other, so that its book stays balanced and it does not face a large loss on one result. This is why a price can move with no announcement at all. Madrid's price to win in Athens went from 1.28 to 1.25 late on Tuesday night and to 1.23 by 02:22 CET on Wednesday, with nothing new published about either team in the sources this site reads. The honest description is that the market moved and no public reason was found. Guessing a reason is not reporting; this site says "no public reason found" when that is the truth. ## What does not count as a move? Prices twitch all day, and most twitches mean nothing. Manchester City's price to win at Leipzig on Wednesday was 1.56 on Friday afternoon and 1.59 on Wednesday morning, after City had lost two league games in a row. That is about one percentage point of chance, which is noise: the sort of change that comes from rounding, from small bets, or from the feed updating a fraction. This site's rule, set out in its working brief, is that a change of three percentage points or more in the chance of a win, a draw or a defeat is a real move worth an article; two to three points earns a sentence; under two is noise, and we say so. The goals line and the handicap, the lines that split a match at a number of goals or give one side a head start, can also appear to move when they have not. The feed picks the line nearest to even money as its main line, so when the prices on two neighbouring lines are both close, the main line swaps between them from one capture to the next. On the Fenerbahçe v Liverpool game the handicap has read Fenerbahçe +1 for most of the week and Fenerbahçe +1.5 for a few captures. That is how the feed works, not the market changing its mind; the market changes its mind when the line moves and stays moved for several captures, as the goals line on that match did when it went from 2.5 to 3.5 on Sunday evening and stayed there. ## When do prices move most? In the hour before kick-off, when the teams are announced. A surprise in the line-up can move a price more in ten minutes than the whole week before. This is why every price on this site carries the time it was captured, and why a preview written in the morning says the official teams are due at a given time rather than pretending the morning price is the final one. The last price captured before kick-off is called the closing line, and it is the fairest single measure of what the market thought, because it includes everything that was known. ## Does a move tell you the result? No. A move tells you what the market now thinks, and by how much that has changed. Liverpool at 1.49 are expected to win roughly two games in three if this one could be played many times; it is played once. The price moved towards Liverpool this week, and Fenerbahçe can still win. A move is information about opinion, not about the result, and this site reads it as such. ## In plain words Odds change because the information changes. Team news moves prices most often, results move them in a single step, and money moves them quietly, sometimes with no public reason at all. Read a move in percentage points of chance, by dividing 1 by each price: three points or more is a real move, under two is noise. Watch the lines as well as the prices, and remember that a line that flips between captures is the feed choosing its main line, not a change of mind. And always read a price with its time, because the next capture may say something different. ## Sources 1.
