Reality Trading Takes Over as Prediction Markets Turn Opinions Into Tradable Outcomes
Wall Street has discovered the ultimate commodity — reality. Prediction markets like Kalshi and Polymarket are turning everyday outcomes into tradeable contracts and letting users put real money on the line. Valuations now hover around $11B and $8B, respectively, while weekly trading volumes are nearing $2B as Americans bet on everything from political events to weather patterns.
- During one Jerome Powell press conference, traders wagered $2.8M betting on which exact words he’d say — including $3 wins on “good afternoon.”
- Goldman Sachs CEO David Solomon called prediction markets “super interesting” and said his firm is actively exploring opportunities in the space.
The odds economy: These platforms argue they turn collective opinion into useful probability signals, but critics say they’re just gambling in disguise.

With moves like Intercontinental Exchange’s $2B bet on Polymarket, the industry looks increasingly set to financialize how society processes information. Welcome to a world where even uncertainty has a price.
