Opening line vs closing line in NBA props

The opening line is the number at which a sportsbook first posts a prop; the closing line is the last number before tip-off. In between, the line can rise, fall or stay the same.

A line moves because of new information: an injury or a return, a change in expected minutes, the pace of the game or betting volume. If a points prop opens at 22.5 and closes at 24.5, the market has adjusted that expectation upwards.

Comparing opening and closing with the final result helps you see how well lines adjust over time and which players or markets move the most. In the History section of BucketsBase you can see how each line moved and how it ended: Over, Under or push. It is context, not a guarantee of results.
