Opinion Labs Emerges as Strong Contender in Prediction Markets Race
Prediction markets are heating up as Opinion Labs becomes the third platform to surpass $700 million in weekly trading volume, joining established leaders Kalshi and Polymarket. The newcomer attracted $748.8 million in notional volume for the week of October 27, 2025—a significant achievement given its recent public launch on November 4.
Kalshi and Polymarket maintain dominance with $1.26 billion and $1.11 billion respectively, but analysts see Opinion's rapid growth as evidence of a brewing arms race. Messari researcher Austin Weiler describes the entry as "potentially major," while decentralized competitor Limitless gains traction on Base network.
