Polymarket is re-entering the United States after closing its acquisition of derivatives exchange QCEX for $112 million.

Polymarket said the transaction paves the way for US users to access Polymarket in the near future within a fully regulated, US-compliant framework.

Founded in the United States in 2020, Polymarket exited the US after being fined $1.4 million by the Commodity Futures Trading Commission (CFTC) for regulatory violations.

QCEX is licensed by the CFTC.

“Polymarket is the largest prediction market globally and has become synonymous with understanding the probability of current events,” said Shayne Coplan, founder and CEO of Polymarket. 

“Demand is greater than ever — not just in user growth and trading volume, but in how mainstream audiences are turning to Polymarket to separate signal from noise, bias, and speculation. Now, with the acquisition of QCEX, we are laying the foundation to bring Polymarket home — re-entering the US as a fully regulated and compliant platform that will allow Americans to trade their opinions.”

Sergei Dobrovolskii, founder of QCEX, commented: “When we began the process to obtain our Designated Contract Market and Derivatives Clearing Organization licenses over four years ago, the prediction market was in its infancy. But we have long believed in its potential to change the way people access and understand information and express their views on that information.

“Shayne has built a cultural phenomenon in Polymarket.  I am excited to bring our companies together and leverage our licenses, technology, and expertise in the retail trading sector to help Polymarket reach its full potential.”
