The predicted market trading volume fell back in February, and Opinion data significantly shrank

The prediction market recorded a total trading volume of $23.4 billion in February, a decline of about 12% from January's record $27.1 billion, ending a five-month upward trend and marking the first monthly drop since August 2025. The decline was mainly dragged down by the BNB Chain platform Opinion, whose trading volume plummeted from over $10 billion to $3.1 billion. Notably, the authenticity of Opinion's data has previously been questioned.

Meanwhile, the performance across platforms was mixed. Kalshi's trading volume rose to a historic high of $9.8 billion, further solidifying its leading position in the industry; Polymarket saw a slight increase, rising from $7.7 billion to $7.9 billion.

In recent years, the prediction market has evolved from a niche tool to a mainstream financial application, widely used for event predictions such as elections and economic indicators.
