Understanding the odds
Prediction market prices reflect the crowd’s estimated probability of an outcome. A YES price of 1% means traders collectively assign roughly that chance to the event happening. Whale alerts flag unusually large volume moves — a signal worth investigating, not a guarantee of insider knowledge.
