Polymarket is launching a U.S. comeback push, including influencer-driven marketing and partnerships with Major League Baseball, major sports teams, and media outlets such as CNBC and CNN, according to CoinDesk, citing an Associated Press report. The prediction market began its return after a four-year U.S. ban with the acquisition of QCEX a year ago and a CFTC-supervised mobile app launched in December that allows real-money sports betting. The effort follows a Wall Street Journal report alleging paid influencer promotions without adequate disclosures and comes after a prior $1.4 million CFTC settlement.
