Context: Prediction Markets

Prediction markets, like Polymarket, allow users to bet on the outcome of real-world events, including sports. The probability displayed by these markets is derived from the prices at which contracts are trading. A contract trading at $0.40, for instance, implies a 40% probability of the event occurring. These probabilities are dynamic and can change based on collective market sentiment and evolving information. A "shock" event, as triggered here, signifies a substantial and rapid change in this implied probability over a short period, suggesting a notable shift in the perceived likelihood of the event's outcome.
