How Basketball Odds Actually Shift
When a game opens, oddsmakers post a point spread or moneyline based on projected team performance. From there, two forces push the number around: heavy public betting on one side, and sharp money — large, informed wagers — that forces the book to recalibrate. An injury report dropping an hour before tip-off can move a spread two or three points in minutes.
Tracking that movement on spree lets you see whether a line is steaming toward one side or sitting flat. Flat lines after big news often mean the market already priced the information in, which is a signal worth noting before you pick your side.
