Blumenthal said, 'My Prediction Markets Security and Integrity Act would require prediction markets to ensure that all bets clearly and conspicuously state the conditions under which they are decided, and that the prediction markets ultimately take responsibility for decisions.' The release says he pressed the CFTC about fair resolution of disputed prediction-market bets and attached a letter seeking answers.

Assessments
The claim promised that Blumenthal would introduce and support legislation with these prediction-market disclosure and responsibility requirements, not that the bill would become law. He introduced the Prediction Markets Security and Integrity Act of 2026 as S.4060 with Senator Kim, and his April 2026 oversight statement explicitly described the bill as requiring clear bet conditions and prediction-market responsibility for outcome decisions. That satisfies the promised legislative introduction and support during his current Senate term.
The promise was to introduce and support legislation requiring prediction markets to clearly state bet conditions and take responsibility for resolving outcomes. The evidence shows Blumenthal publicly backed that exact policy, pressed the CFTC on disputed bets, and introduced the Prediction Markets Security and Integrity Act of 2026 with language matching the commitment. Because the promised action was introduction/support of legislation rather than enactment, passage is not required for full delivery.
