What Drives Basketball Odds from Open to Tip-Off
When a NBA spread opens on Sunday night, sportsbooks are essentially making a pricing decision with incomplete information. Sharp bettors — those with a consistent winning record — hit the early number fast. That forces an adjustment. Hours later, casual money floods in from the public, sometimes pushing the line back. Injury news mid-week creates a second wave of movement, and load-management
scratches close to tip-off can swing a spread two or three points in minutes. Tracking those waves, not just the final number, is what separates a well-timed bet from one placed at a stale price.
