Polymarket says annualized revenue tops $1 billion as U.S. exchange volumes climb and World Cup boosts trading

The prediction market operator said its annualized revenue is now well above $1 billion, with U.S. daily volume rising past $200 million and international activity hitting records during the FIFA World Cup.

Fact Check
The original source, The Block's June 24, 2026 article, directly supports every element of the claim: Polymarket's soccer/football category volume up 300% to over $2 billion in the first ten days of the World Cup, and Kalshi open interest hitting a record $1.16 billion (its first time over $1 billion). Three independent republications (cryptobriefing, panewslab, odaily) carry identical figures and all cite The Block. The figures derive from The Block's own prediction-market data dashboards. The only caveat is that all evidence ultimately traces to a single original reporter (The Block), so independent confirmation from Polymarket/Kalshi primary data was not directly verified here, slightly limiting certainty.
Summary

Polymarket said its annualized revenue is now well above $1 billion, marking a new financial milestone as trading activity accelerates across both its U.S. and international platforms. The update comes six weeks after the company removed the waitlist for its CFTC-regulated U.S. exchange on mobile, and as the FIFA World Cup drives a surge in prediction-market volumes. Data cited from Dune Analytics showed volume on Polymarket’s U.S. platform rising from around $50 million a day in mid-May to more than $200 million on June 20. On its international decentralized finance platform, weekly trading volume reached all-time highs during the World Cup after declines in April and May. The new figures add to signs of broad event-driven growth in the sector. Polymarket’s football-category trading volume had already topped $2 billion in the first 10 days after the World Cup began, up 300% from the prior 10 days, while average daily volume rose from $53 million to about $220 million. Kalshi’s aggregated open interest also reached a record $1.16 billion last Thursday, crossing $1 billion for the first time. Polymarket launched its U.S. exchange in December after being barred from operating in the country in 2022 for failing to properly register with regulators. The Commodity Futures Trading Commission and the Department of Justice dropped their investigations into the company without charges in July, and the U.S. platform now operates as a CFTC-regulated exchange. The mobile app is live for U.S. users, while a desktop version remains unavailable.
