Sharp money refers to disciplined, model-driven traders whose flow is more predictive of true market probability than recreational flow.
In every market, traders split roughly into sharps (price-driven, exit on edge) and squares (sentiment-driven, hold to resolution). Sharp money moves prices toward fair value; square money moves them toward narrative.
Sharps usually enter prematch, scale into large positions, and exit before the line moves too far against them. Square flow clusters live, around marquee moments. Our signals page classifies new trades against the known-sharp wallet list in real time.
