US President Donald Trump has backed the Commodity Futures Trading Commission as having the âexclusive authorityâ over prediction markets, as state regulators’ action against the platforms mounts.
âIt is critically important that the CFTCâs exclusive authority over Prediction Markets is maintained, and that they will thrive,â Trump posted to his social media platform Truth Social on Tuesday.
Trump also took aim at several officials whose states have launched legal action against prediction markets, including Kalshi, Polymarket, Crypto.com and Robinhood.
âUnder my leadership, we are setting ârules of the roadâ that are the Gold Standard for the States,â Trump wrote. âWe cannot have SCUM like Chris Christie, Letitia James, Tim Walz, and JB Pritzker setting the rules!â

Multiple state authorities have argued that prediction markets are violating state laws by offering gambling without a license, and have sued or issued cease-and-desist orders to multiple platforms.
Prediction markets such as Kalshi have sued various state authorities to fend off legal action, claiming it is regulated solely by the CFTC.
CFTC Chair Mike Selig has also opposed the states, arguing his agency has âexclusive jurisdictionâ over prediction markets as federally regulated designated contract markets.
The agency has sued several states, including Minnesota, Illinois, New York and Arizona for taking action against prediction markets.
Trump said in his post that âother Countries are after this new form of Financial Market, and we want to remain at the top.â
âIt is a major Industry, and we must protect it,â he added.
Last month, Trump told reporters he was ânot happyâ with prediction markets and was ânever much in favorâ of them in response to a question about well-timed bets on the platforms on events linked to the Iran war, which has drawn the ire of several Democrats who have called for stricter measures.

Trump, whose son Donald Trump Jr. is invested in and on the advisory board for Polymarket and is also an adviser to Kalshi, softened his stance on prediction markets days later, saying the US would âget left out in the coldâ if it didnât allow the platforms.
In March, the CFTC established an advisory team to oversee the listing and trading of event contracts and to ensure that market participants satisfy anti-manipulation, surveillance and market integrity requirements.
It claimed that prediction markets fall within the CFTCâs existing derivatives framework under the Commodity Exchange Act.
