My measure—the Prediction Markets Security and Integrity Act—puts guardrails on this out-of-control industry. It bans dangerous and unethical bets and protects consumers from fraud and other predatory practices.
Introduce and support legislation to regulate prediction markets by banning listings related to war, death, and military action; enforcing rules against insider trading and market manipulation; requiring consumer protections; and preserving state gambling regulatory authority.

Assessments
Verified evidence shows Blumenthal materially delivered the introduction component: GovInfo says he introduced the bill, and the verified Senate passage confirms key provisions on insider trading, market manipulation, and bans on war, death, and military-action prediction-market listings. The verified commitment also shows his own support for the measure. However, the verified passages provided do not prove every claimed component, especially preserving state gambling regulatory authority, so full delivery is not established from verified evidence alone.
Blumenthal fulfilled the promise as framed because it required introducing and supporting legislation, not securing enactment. Official records and Senate materials show he introduced S. 4060, the Prediction Markets Security and Integrity Act of 2026, during his current Senate term, and the bill contains the promised bans on war, death, and military-action listings; insider trading and manipulation rules; consumer protections; and preservation of state and tribal regulatory authority. His later CFTC oversight letter also shows continued support for the same agenda.
