Understanding Prediction Markets:

Prediction markets like Polymarket allow users to bet on the outcome of future events. The probabilities displayed on these platforms represent the collective belief of the market participants regarding the likelihood of a specific outcome. For example, a probability of 0.995 means the market assigns a 99.5% chance to that particular outcome occurring. These probabilities are dynamic and can change based on new information, sentiment shifts, and trading activity. An "odds shock," as observed here, refers to a rapid and substantial change in these probabilities, often driven by new data or a concentration of trading activity. A `deltaPct` of 10.5% signifies a substantial movement in the underlying probability calculation within the observed timeframe. The absence of recent trading volume may indicate a price discovery phase has concluded, or the market is awaiting further catalysts.
