Polymarket weekly trading volume tops $4B
Polymarket's weekly trading volume crossed $4 billion, the platform announced this week. The figure covers combined activity across its US and international platforms. The US exchange operates under a Commodity Futures Trading Commission (CFTC) order of designation after acquiring licensed exchange QCEX (QCX) in 2025. The milestone comes as regulated prediction markets compete for activity ahead of major political and sporting events.
The $4 billion figure puts concrete scale behind Polymarket's CFTC-regulated US exchange at a moment when volume itself is the competitive scorecard. Kalshi just posted $6 billion, so the two directly designated platforms are now racing in public view. Retail brokers like Robinhood route through partners rather than holding their own licenses, so they cannot match these headline numbers with owned infrastructure.
For traders, the split matters because direct designation means Polymarket and Kalshi control their own compliance and cannot be delinked by a partner dispute. The platform that sustains higher flow outside NFL seasonality will set the revenue model rivals must copy. Polymarket's celebrity spending and Kalshi's brokerage integrations are competing bets on how to acquire that flow. Neither yet knows which strategy converts more cheaply.
