A16z filed a brief backing the CFTC against state-level efforts to ban prediction market platforms Kalshi and Polymarket. The venture capital firm argues that state restrictions conflict with federal regulatory authority and deny retail users access to legal betting markets.
Prediction markets allow users to trade contracts tied to real-world events. Kalshi operates under CFTC oversight as a registered derivatives exchange. Polymarket, though unregistered, has operated in a legal gray zone by restricting U.S. traders while accepting bets from international users.
State attorneys general have pushed back against these platforms, citing consumer protection concerns and gambling laws. A16z counters that federal commodities law preempts state action and that ordinary investors lose access to price discovery tools when states impose bans.
The dispute reflects broader tension between state and federal authority in crypto regulation. CFTC Chairman Rostin Behnam has signaled openness to prediction markets, positioning the agency as the primary regulator. A16z's intervention signals that major venture players view this space as commercially viable and worth defending against fragmented state-level restrictions.
The outcome will shape whether prediction markets expand as a mainstream financial product or remain confined to offshore alternatives.
