The Commodity Futures Trading Commission's Division of Market Oversight and the Division of Clearing and Risk said Wednesday they have taken a no-action position regarding swap data reporting and recordkeeping regulations for event contracts in response to a request from QCX, a designated contract market, and QC Clearing, a derivatives clearing organization.

The no-action letter applies in "narrow circumstances", the statement said, and is comparable to no-action letters issued for other similarly situated designated contract markets and derivatives clearing organizations. After a federal investigation was dropped earlier this summer, Polymarket said in July it planned to re-enter the U.S. with the acquisition of derivatives exchange QCEX.
