Polymarket US volume surges 266% as annualized revenue hits $1.8 billion
Monthly trading volume on Polymarket US rose 266% from June to October, the platform said. Annualized revenue exceeded $1.8 billion. Sports betting drove the jump. The growth comes while Polymarket faces ongoing regulatory disputes. The platform operates through QCX LLC, a CFTC-regulated designated contract market it acquired. State attorneys general in Ohio and Tennessee have challenged its contracts. The CFTC is separately weighing rules that could reclassify some event contracts as swaps.
The $1.8 billion run rate deepens the revenue gap with partner-dependent platforms. Robinhood's $173 million in Q3 event-contract revenue relies on Kalshi and Rothera infrastructure it does not control. Polymarket's direct CFTC designation through QCX offers traders continuity if partner outages recur. That stability pitch matters after August disruptions showed retail traders abandon interrupted platforms within days.
But the 70% concentration in combo contracts is politically exposed. State attorneys general argue bundled outcomes amplify gambling risk. A single CFTC swap-rule redesign or state injunction against that product type could erase most revenue. Competitors must now match this scale or concede the high-volume trader segment.
The milestone joins Polymarket's media placement push through On3 college football previews as the latest evidence that regulated prediction markets are becoming referenceable trading infrastructure rather than a novelty product.
