The prediction market comeback is REAL. October saw prediction markets return to the spotlight. After a quiet period following the 2024 U.S. election, trading activity has surged again. In Q3 2025, volumes hit new highs—driven by an intense rivalry between Kalshi and Polymarket. 1️⃣ Two giants, two paths ICE, the parent company of the NYSE, invested $2B in Polymarket at a $9B valuation. A few days later, Kalshi raised $300M at a $5B valuation. Both platforms are expanding fast, but their strategies are fundamentally different. Kalshi is playing the regulated, mainstream route—integrating directly into Robinhood so users can trade within the app. Polymarket stays crypto-native—running on Polygon with fully on-chain settlement and transparent outcomes. Kalshi now commands over 60% of global market share, surpassing Polymarket for the first time—marking a key power shift in how retail prediction liquidity flows.
