US Senators Introduce “Prediction Markets Security and Integrity Act” to Tighten Oversight of Online Betting Platforms

Quick Summary

• US lawmakers introduce the “Prediction Markets Security and Integrity Act” targeting online prediction market oversight.
• The bill seeks to prohibit fraud, insider trading, and underage participation on prediction platforms.
• Proposed requirements include enhanced regulatory supervision of market operators and stricter consumer protection measures.
• The legislation responds to rapid growth in the US prediction market sector, raising questions about its legal and ethical frameworks.

What Happened

On March 13, 2026, US Senator Richard Blumenthal (D-CT), joined by Senator Andy Kim (D-NJ), unveiled the “Prediction Markets Security and Integrity Act.” This piece of federal legislation is designed to impose a suite of regulatory controls over online prediction markets. The bill addresses emerging concerns over fraud, insider trading, and the participation of minors, issues that have attracted increased national attention as platforms enabling real-money betting on future events multiply in prominence.

If enacted, the act would establish explicit prohibitions on insider trading by individuals and operators of such markets, mandate robust age-verification protocols to keep minors from participating, and require market operators to comply with new federal standards aimed at preventing market manipulation and other forms of wrongdoing.

Why It Matters

The exponential growth of prediction markets—digital platforms allowing betting on outcomes in politics, public affairs, science, and even entertainment—has placed US regulators at a crossroads. These markets, typified by operators like PredictIt and, more recently, Kalshi, have rapidly migrated from academic exercises to mass-market products drawing millions of dollars in wagers and widespread media coverage, particularly around US elections.

Yet, their regulatory status has remained murky, situated at the intersection of gambling law, securities regulation, and First Amendment protections. While the US Commodity Futures Trading Commission (CFTC) has occasionally intervened—most recently with actions against PredictIt’s political markets—the lack of a clear, comprehensive federal regime has left prediction markets exposed to exploitative practices and legal challenges.

The “Prediction Markets Security and Integrity Act” directly addresses these gaps. By introducing federal standards prohibiting insider trading and mandating fraud prevention measures, lawmakers aim to install the same integrity protections that govern traditional regulated gambling as well as securities markets. The explicit requirement for robust age-verification seeks to address the risk of underage and vulnerable populations gambling on uncertain outcomes—a central issue for responsible gambling advocates.

For industry stakeholders, the bill signals intensifying scrutiny and a likely wave of compliance obligations. Operators will be required to implement advanced surveillance and reporting systems, potentially reshaping product design and user onboarding. The move also underlines mounting congressional concern over prediction markets serving as conduits for problematic betting behavior, corruption, or the subtle manipulation of public discourse by those with inside knowledge.

Industry Context

The emergence of online prediction markets in the US is part of a global trend that blurs the line between regulated gambling and financial speculation. Internationally, platforms like Betfair’s Exchange and Smarkets have long offered similar markets under gambling or financial regulation depending on jurisdiction. In the US, existing legal frameworks have struggled to keep pace with technological innovation and the unique characteristics of event-based betting on markets outside traditional sports or casino gaming.

Kalshi, the first federally regulated US event contracts exchange, received CFTC approval in 2021 to offer certain markets, marking a tentative legitimization of the vertical. However, recent enforcement actions and public hearings have underscored ongoing debates about the limits of permissible wagers and the measures needed to ensure transparency and consumer protection.

With the 2024 US elections driving explosive interest in political prediction markets and millions in notional value traded, lawmakers have faced increasing pressure from advocacy groups alarmed at potential social and political risks, as well as from technologists concerned about stifling innovation.

Regulatory Background

Historically, prediction markets in the US have occupied a legal grey area. While wagering on sporting and casino outcomes falls under the purview of state-licensed gambling regulators, the CFTC oversees derivatives and event contracts markets when they qualify as commodities. Some academic projects, like the Iowa Electronic Markets, have operated under special no-action relief due to their research focus and limited scale.

The growth of commercial platforms has pushed boundaries, prompting the CFTC to seek greater clarity. The agency, however, remains divided over whether event-based contracts on elections or public outcomes constitute illicit gambling, legal derivatives, or something else entirely. The new Senate bill seeks to fill regulatory gaps by establishing clear federal mandates concerning market integrity, fraud prevention, and access restrictions—areas not always addressed under state law.

What Happens Next

The “Prediction Markets Security and Integrity Act” faces the standard federal legislative process, requiring committee review, potential amendments, and votes in both chambers. Should it gain traction, regulated prediction market operators will need to prepare for a more demanding compliance landscape, while industry observers watch closely for further guidance from both legislators and federal regulators.
