Senators Warren, Curtis Press Kalshi and Polymarket on Election Trading Safeguards

The significance here is less the questions themselves than the venue: prediction markets are being pulled into the same congressional scrutiny that has long trailed crypto and derivatives platforms, and the pre-trade focus signals where lawmakers see the risk. Kalshi and Polymarket are directly affected, but so is the broader event-contract sector, which now faces a template for how election-related surveillance will be judged. The open question is whether the November 3 responses disclose concrete pre-trade controls, and whether that record becomes the basis for further legislative or regulatory attention.
