Warren, Curtis Press Kalshi and Polymarket on Election-Bet Insider Trading

The scrutiny lands as a credibility test for event contracts: the senators are not asking whether election betting should exist, but whether these platforms can substantiate the preventive controls they claim. That distinction matters because the requested breakdown — blocked before execution versus caught afterward — is exactly the evidence that would separate real surveillance from post-hoc cleanup. For Kalshi and Polymarket, the November 3 written replies will effectively become a public benchmark, and whether the firms can supply concrete enforcement data, rather than procedural assurances, is the open question.
