Prediction market trading volume declined in February, with Opinion data shrinking significantly

ChainCatcher news, the total trading volume of prediction markets in February recorded 23.4 billions USD, down about 12% from the record 27.1 billions USD in January, ending five consecutive months of growth and marking the first monthly decline since August 2025. The downturn was mainly dragged by the BNB Chain platform Opinion, whose trading volume plunged from over 10 billions USD to 3.1 billions USD. It is worth noting that the authenticity of Opinion's data has previously been questioned by outsiders.

Meanwhile, platforms showed divergent performances. Kalshi's trading volume rose to a historical high of 9.8 billions USD, further consolidating its industry-leading position; Polymarket saw a slight increase, rising from 7.7 billions USD to 7.9 billions USD.

In recent years, prediction markets have evolved from niche tools to mainstream financial applications, widely used for forecasting events such as elections and economic indicators.
