What Is the Blumenthal-Kim Prediction Market Bill?

The Blumenthal-Kim bill is a federal legislative proposal introduced on March 12, 2026, that would explicitly reverse the CFTC's claimed exclusive jurisdiction over prediction markets, stating that these platforms are NOT exempt from state gambling laws. The bill also targets insider trading on prediction markets and introduces enhanced customer protections for retail traders.

Key Provisions of the Bill

The legislation addresses three main areas:

1. Reversing Federal Preemption

The most consequential provision directly challenges CFTC Chair Michael Selig's position that the Commodity Exchange Act gives the CFTC exclusive regulatory authority over prediction markets:

• States would retain authority to regulate prediction markets under their gambling laws
• Prediction market operators could be required to obtain state gaming licenses in addition to CFTC registration
• The CFTC's preemption argument in ongoing federal lawsuits (including Kalshi's suits against state regulators) would be undercut

This is a direct legislative response to the CFTC's formal guidance, released on the same day the bill was introduced.

2. Insider Trading Protections

The bill creates specific prohibitions against insider trading on prediction markets:

• Trading on material nonpublic information related to a prediction market event would be prohibited
• This addresses high-profile incidents where traders appeared to profit from advance knowledge of government actions, military operations, and corporate announcements
• Enforcement mechanisms would apply to both the traders and the platforms that facilitate suspicious activity

3. Customer Protection Enhancements

Additional consumer protection measures include:

• Enhanced disclosure requirements for prediction market operators
• Protections for retail traders who may not understand the derivative nature of event contracts
• Transparency requirements around market-making practices and platform fees

Who Introduced It?

The bill is co-sponsored by:

• Senator Richard Blumenthal (D-CT) — a member of the Senate Judiciary Committee with a history of consumer protection legislation
• Senator Andy Kim (D-NJ) — whose state hosts a significant regulated gambling industry, including Atlantic City casinos and licensed sportsbooks

The bipartisan dynamic is notable: while the Trump administration's CFTC supports prediction market growth under federal oversight, Democratic senators are pushing back with legislation that would preserve state authority.

Why It Matters for iGaming Operators

If the Blumenthal-Kim bill passes:

• Prediction markets would need state licenses — potentially the same state gaming frameworks operators already work within
• Dual-regulation (federal CFTC + state gaming) would become the standard, increasing compliance costs for prediction market entrants
• Existing licensed operators would gain a competitive advantage, as they already hold the state licenses prediction markets would need to obtain
• The $600 million tax revenue gap would begin to close as states could impose gaming taxes on prediction market activity

If it fails:

• The CFTC's exclusive jurisdiction claim strengthens
• Prediction markets continue operating outside state gaming tax structures
• State enforcement actions face an uphill legal battle

Current Status

As of late March 2026, the bill has been introduced but no committee hearing has been scheduled. Its prospects depend heavily on the broader political dynamics around prediction market regulation and the outcome of ongoing federal court cases.

Frequently Asked Questions

Could the Blumenthal-Kim bill actually pass?

The bill faces challenges in the current Congress, where the Trump administration generally supports lighter federal regulation of prediction markets. However, the $600 million tax revenue argument has bipartisan appeal — state legislators from both parties care about budget shortfalls. A compromise version that preserves CFTC oversight while allowing state taxation could attract broader support.

How does this differ from state-level legislation?

State legislation can only address prediction markets within individual state borders. The Blumenthal-Kim bill would establish a federal framework that applies nationwide, resolving the current patchwork of contradictory state approaches and court rulings.

What would dual regulation look like?

Under dual regulation, prediction market operators would need CFTC Designated Contract Market registration for their financial product structure, plus state gaming licenses for each state where they want to offer sports event contracts. This mirrors how some financial products face both federal SEC/CFTC oversight and state-level regulation.
