Venture capital firm a16z argues that state crackdowns on platforms like Kalshi and Polymarket conflict with federal law and hurt market access for ordinary users.
A16z has thrown its weight behind the Commodity Futures Trading Commission (CFTC) in a growing federal-state standoff over prediction markets, opposing state regulators that try to shut down platforms like Kalshi and Polymarket.
The venture capital heavyweight submitted the letter on Thursday in response to the CFTC’s advance notice of proposed rulemaking on prediction markets. It argues that state-level crackdowns, ranging from cease-and-desist letters to criminal charges, are creating barriers that undermine the federal agency’s mandate to provide “impartial access to its markets and services.”
In recent weeks alone, the CFTC has filed lawsuits against Illinois, Arizona, Connecticut, New York and Wisconsin, claiming that those states overstepped by trying to regulate markets that fall under federal jurisdiction. A16z backed that position, arguing that forcing exchanges to block users based on their state of residence directly conflicts with the CFTC’s impartial access rules.
