Understanding Prediction Markets:

Polymarket operates on a prediction market mechanism where users buy and sell "shares" of potential outcomes. The price of a share directly translates to the market's perceived probability of that outcome occurring. A probability of 0.9995, or 99.95%, implies the market collectively assigns a near-certainty to that particular outcome. Conversely, a lower probability suggests a lower perceived chance. These probabilities are dynamic and can change based on new information, trading activity, and shifts in collective sentiment. The `odds_shock` trigger specifically alerts users to significant, rapid changes in these probabilities, prompting further investigation into the underlying market activity and potential market-moving information.
