a16z Urges CFTC to Assert Federal Authority Over Prediction Markets

Venture capital firm Andreessen Horowitz has called on the Commodity Futures Trading Commission to establish a unified federal framework for prediction markets, warning that fragmented state-level enforcement risks undermining the sector’s growth.
Summary:
- a16z urged the CFTC to override state-level restrictions on prediction markets.
- The firm warned fragmented rules could drive liquidity offshore.
- It called for case-by-case oversight instead of blanket bans.
In a formal comment letter submitted on April 30, the firm argued that current regulatory inconsistencies are creating barriers to access and pushing market activity outside the United States.
Call for Federal Preemption Intensifies
At the center of the filing is a push for stronger federal oversight. Andreessen Horowitz argued that the CFTC should reaffirm its exclusive jurisdiction over designated contract markets.
The firm pointed to recent enforcement actions by states such as Arizona, Connecticut, and Illinois, which have attempted to restrict prediction market platforms under local laws. According to a16z, these actions conflict with federal authority and create legal uncertainty for operators.
A unified framework, the firm said, would provide consistency and prevent a fragmented regulatory landscape that limits scalability.
State Restrictions Seen as Barrier to Access
a16z also raised concerns about how state-level rules affect user participation. Platforms often restrict access based on geographic location to comply with local regulations.
The firm argued that such limitations contradict the CFTC’s mandate for “impartial access,” which focuses on financial and operational criteria rather than residency. By forcing platforms to segment users, state actions risk undermining the fairness and openness of these markets.
This issue has become increasingly prominent as prediction platforms expand their user base across multiple jurisdictions.
Opposition to Broad Prohibitions
The filing specifically challenges existing restrictions on certain event-based contracts. a16z criticized blanket prohibitions and called for a more flexible regulatory approach.
Instead of outright bans, the firm proposed a case-by-case evaluation based on public interest considerations. This approach would allow regulators to assess risks without limiting innovation across the entire sector.

The recommendation aligns with broader industry efforts to replace rigid rules with adaptive oversight frameworks.
Rapid Market Growth Raises Stakes
The push for regulatory clarity comes as prediction markets experience rapid expansion. Trading volumes on platforms such as Kalshi have grown significantly, reflecting increasing demand for event-based financial instruments.
a16z argued that the current regulatory structure has not kept pace with this growth. Without clear federal guidance, the firm warned that liquidity could shift to offshore platforms where oversight is less restrictive.
Such a shift, it said, could weaken U.S. market integrity and reduce investor protections.
Blockchain Proposed as Compliance Tool
In addition to regulatory recommendations, a16z highlighted the potential role of blockchain technology in addressing oversight concerns. Transparent, on-chain records could provide real-time audit trails, improving visibility into transactions and reducing risks of manipulation.
The firm suggested that integrating these tools into regulatory frameworks could enhance compliance while supporting innovation.
Regulatory Debate Enters Critical Phase
The submission comes as the CFTC gathers input through its Advance Notice of Proposed Rulemaking on prediction markets. The agency has also launched initiatives aimed at modernizing oversight for emerging technologies, including AI-driven financial systems.
As tensions between state and federal authorities intensify, the outcome of this process could shape the future of prediction markets in the United States.
For now, Andreessen Horowitz’s intervention underscores a broader industry push for clarity, consistency, and a regulatory framework capable of supporting the next phase of market development.
