OddScore tracks 3 basketball markets. The match winner, with 2 outcomes because there's no draw. The spread, which hands one team a points margin. And over/under points, on the combined score. The competitions are the NBA and EuroLeague. The method is the one used for football and tennis (odds movements, real probabilities, 0-100 signal), applied to these 3 markets.
The winner market: two outcomes, never a draw
A basketball game can't finish level. If the scores are tied at the end of regulation, they play overtime, and then more overtime if they need to. That leaves the winner market with just 2 outcomes. Football has 3. That's why I can read basketball more easily than football: one price shortens, the other drifts.
The method doesn't change from one sport to the next. OddScore collects odds from several bookmakers, compares how they move, converts them into real probabilities and turns that into a signal from 0 to 100.
A real case. FC Barcelona Bàsquet v Anadolu Efes, in the EuroLeague. With only two outcomes, the two margin-free prices move as mirror images. When one shortens, the other drifts. Here, Anadolu Efes go from 2.78 to 1.94 over the four days before the game. Barcelona go from 1.56 to 2.07. The market favourite switches sides. The chart shows the move; it doesn't tell you what caused it.
From 20 September to the start, the margin-free odds on “Anadolu Efes win” moved from 2.78 to 1.94 (−30.35%), a margin-free probability of 35.96% then 51.63%. Lowest value seen: 1.94; highest: 2.91. This chart describes a past market movement: it says nothing about the match result and is not betting advice.
| Outcome | First tracked odds | Last odds before the start | Change | Margin-free probability (first, then last) |
|---|---|---|---|---|
| FC Barcelona Bàsquet win | 1.56 | 2.07 | +32.42% | 64.06% then 48.38% |
| Anadolu Efes win | 2.78 | 1.94 | −30.35% | 35.96% then 51.63% |

On this chart, everything turns on the point where the two lines cross. Before it, Barcelona are favourites. After it, Efes are. There's no draw to soak up any of the probability, so whatever one side loses, the other picks up.
The spread market
OddScore also tracks the spread, which you'll also see called the handicap. How it works, its different families and how bets on it are settled are all covered on the handicap betting page.
Here, it gets the same treatment as every other market. Odds movements, a comparison across bookmakers, a 0-100 signal. The spread is tracked on its own, separately from the winner and the over/under.
The over/under points market
Third up, over/under points. You're looking at the combined score of both teams, above or below a line. For the line, the odds and the rest, the Over/Under page explains how the market works in general.
Bookmakers cover this market particularly well on basketball. That's what lets OddScore produce a reliable signal on it.
When all three markets move together
Picture an NBA game (fictional example). The favourite's odds shorten. At the same time, the spread widens in their favour and the total points line goes up. Those moves often travel together. If the market expects a comfortable win for the favourite, the spread and the total can climb side by side. If it looks like a tight game, each market heads its own way.
OddScore tracks all three separately and checks whether they tell the same story or contradict each other. A strong signal is when several markets point the same way.
The NBA and EuroLeague, to start with
OddScore covers the NBA and EuroLeague. They're the two basketball competitions bookmakers follow most closely in Europe. Others could be added, depending on the coverage available.
A read on the market, with no bet slip to copy
Just as with football and tennis, OddScore doesn't hand you a bet to follow blindly. Before each game, the app shows you the odds movements, the real probabilities and the bookmaker signals. The AI reading sums up what the market is saying, with a verdict (winner, spread or total). That verdict isn't a bet to follow, and it comes with no staking advice. Nothing is guaranteed.
The bit to hang on to: in basketball, as everywhere else, OddScore doesn't give you a bet to copy. It helps you understand what the market is saying.

Which basketball markets does OddScore analyse?
Three. The match winner (2 outcomes, no draw), the spread (a points margin between the two teams) and over/under on the total points scored in the game. They're the most liquid basketball markets at the bookmakers.
Does OddScore cover the spread (handicap) in basketball?
Yes, it's one of the 3 markets tracked, along with the winner and over/under points. The bookmaker gives one team a points margin to balance the odds. OddScore reads it with the same method as the other markets.
Which basketball competitions are covered?
The NBA and EuroLeague, to start with. More competitions could follow, depending on bookmaker coverage.
Why can't a basketball game end in a draw?
Because it's played until someone wins. If the scores are level at the end of regulation, the teams go to overtime. So, as in tennis, the winner market has only 2 outcomes, against 3 in football.
Does OddScore give basketball tips?
No, and it gives no staking advice either. OddScore helps you read odds movements and market signals on the winner, the spread and over/under points. The AI reading sums up what the market is saying with a verdict, but that verdict isn't a bet to follow.
Sources & methodology
This page covers the basketball markets OddScore tracks (winner, spread, over/under points) and the competitions it follows. The analysis method itself lives on the How it works page, shared across every sport. The overtime rule comes from the official NBA rulebook. The other two links point to the British regulator and to support for players.
- Record odds from several bookmakers on the winner market and track how they move.
- Track the spread market between the two teams.
- Track the over/under market on total points.
- Convert odds into real probabilities to strip out the bookmaker's margin.
- Boil it all down to a simple 0 to 100 signal, backed by an AI reading.
