What is Sharp (Sharp Bettor)?
A professional or consistently profitable bettor whose wagers move market prices.
Definition
A sharp is a bettor whose edge is large enough that their bets materially move the market price. When a sharp places a wager, soft bookmakers shorten the line; other bettors and books use sharp action as an informational signal. Characteristics: large stake per bet ($1,000–$50,000+), consistent positive CLV, model-driven selection, account limited by soft books. Soft bookmakers actively track sharp IP addresses, account histories and bet patterns to restrict access. The opposite of a sharp is a 'square' or recreational bettor whose bets the book prices against deliberately.
Example
A sharp bets $5,000 on Kansas City at -6.5. Within minutes, every book shifts to Kansas City -7.5. The sharp's bet signalled private model information the market hadn't priced.
