Polymarket is taking a big step toward re-entering the U.S. market. The company just spent $112 million to buy QCEX, a regulated exchange and clearinghouse. This Polymarket US expansion could soon let American users legally trade on its prediction markets.

• The $112 million deal includes QCX, LLC (a CFTC-licensed exchange) and QC Clearing LLC, both under the QCEX brand. The acquisition gives Polymarket the licenses it needs to operate within U.S. regulatory guidelines. This is a major piece in Polymarket’s effort to become fully compliant in the U.S.

• Polymarket has already processed around $6 billion in user predictions during the first half of 2025. That trading volume highlights the growing appetite for real-time, event-based markets. The U.S. expansion is expected to further increase engagement and liquidity.

• CEO Shayne Coplan said the move marks the start of “bringing Polymarket home.” He pointed to a rising demand among users looking for clarity over speculation and noise. The platform plans to build a compliant path for U.S. users to trade their opinions legally.

• QCEX founder Sergei Dobrovolskii said the acquisition brings together licenses, technology, and expertise in retail trading. “Shayne has built a cultural phenomenon in Polymarket,” he added. Dobrovolskii started QCEX over four years ago with a focus on regulated market infrastructure.
