A recent report indicates that the global prediction market sector is projected to expand significantly, potentially reaching a total volume of £8 trillion by 2035, with a shift away from sports-centric activity.

Analysis from casino.org suggests a substantial growth trajectory for prediction markets over the next decade. The sector, which allows participants to wager on future outcomes of events, is estimated to see its total volume climb to approximately £8 trillion by the year 2035.

This projected expansion is accompanied by an anticipated change in market composition. The report indicates that the share of prediction market activity related specifically to sports events is expected to decrease over the same period. This suggests a diversification of prediction market usage, moving beyond traditional sports betting and into other areas where event contracts can be traded.

Prediction markets operate by allowing users to buy and sell contracts whose value is tied to the probability of a future event occurring. For example, a contract predicting a specific political outcome might be priced at 50p, implying a 50% chance of that event happening. The price of these contracts fluctuates based on collective market sentiment, providing a real-time aggregated forecast. The potential shift away from sports implies growing interest in forecasting outcomes in other domains, such as politics, finance, and current events.
