Caixin: Polymarket’s use of USDC for settlement and delivery poses a significant legal risk to participants within China.

According to an article published by Caixin titled “Financial Innovation or Insider Trading? The Rise and Controversy of Polymarket,” when insider information can be openly monetized, the boundary of prediction markets has already become blurred—raising questions about whether such markets are merely “gambling” disguised as finance, or even涉嫌 insider trading. Yet regardless of the legal debate over whether such activities constitute gambling, the fact that Polymarket uses the USDC stablecoin for settlement and delivery itself poses a significant legal risk for participants within China. Previously, U.S. Senators Jeff Merkley and Amy Klobuchar introduced the “End Prediction Market Corruption Act,” which prohibits the President, Vice President, and members of Congress from trading on prediction markets and requires that the prediction market trading activities of their spouses and dependents be included in annual financial disclosures.
