Polymarket acquired QCEX, a CFTC-licensed derivatives exchange and clearinghouse, for $112 million to expand its regulated prediction market platform in the U.S. This acquisition was completed in July 2025 and was part of Polymarket's strategy to re-enter the U.S. market after previous regulatory challenges. The company also secured a CFTC no-action letter, which cleared the way for its U.S. operations. Additionally, Polymarket raised $2 billion in a strategic investment from Intercontinental Exchange, valuing the company at approximately $9 billion post-money. This investment was aimed at supporting Polymarket's growth and potential U.S. re-entry. Furthermore, Polymarket raised $200 million in June 2025, led by Founders Fund, achieving a valuation of $1 billion, marking its status as a unicorn in the prediction market sector. However, the company experienced a decline in user activity, with daily active traders dropping from 51,930 at the end of March to 27,674 by June 24, and monthly new accounts falling from 408,804 in February to 145,736 in May.
