How NBA Point Spreads Actually Work
A point spread assigns a margin to each game — the favorite must win by more than that number, the underdog must lose by fewer (or win outright). Our NBA Basketball Odds Board shows the current line, juice, and movement in real time. Lines typically open two days before tip-off and shift as money flows in on either side. Sharp movement —
where the line jumps half a point or more in an hour — often signals professional action. Reading that movement is as important as reading the opening number itself. We keep the line history visible on every NBA market so you can track where a spread started and where it sits now.
