CFTC no-action letter exempts non-custodial prediction market software from broker registration
The Commodity Futures Trading Commission's Market Participants Division issued a no-action position on September 17 freeing non-custodial software developers from introducing broker registration requirements in the prediction markets space. The letter covers passive software providers building infrastructure for regulated derivatives, including event contracts and perpetual contracts, so long as they do not take custody of user funds. The move reduces regulatory friction for developers supplying technology directly to registered entities.
Developers building prediction market interfaces, routing layers, and analytics tools can now operate without the costly broker-dealer registration that previously chilled innovation. This lowers the barrier for startups to supply software to CFTC-registered platforms like Kalshi and Polymarket. The letter draws a bright line: custody triggers registration, code alone does not. Engineers who feared building anything that touched order flow now have safe harbor.
The timeline matters because platforms are racing to reformat odds displays and defend state preemption cases; cheaper tooling helps them move faster. But the exemption is narrow. Any developer that takes user funds or executes trades crosses back into broker territory. The CFTC will likely watch for boundary-testing as the passive-versus-active distinction gets litigated in practice.
