President 
Donald Trump wrote on Truth Social that it is "critically important" for the Commodity Futures Trading Commission to maintain "exclusive authority" over prediction markets, attacking state officials suing platforms over the issue as "scum." The post puts the White House squarely behind CFTC Chair Michael Selig's federal-pre-emption push — the Guardian's account framed the language as unusually direct for a regulatory dispute, while CoinDesk read it as cover for Selig's expansion campaign.
What sparked the post? Several states have moved to ban or impose their own regulations on platforms including Kalshi and Polymarket, framing the contracts as a form of gambling that falls under state law — a position the federal government must keep authority over the "multibillion-dollar" market against, Trump said in the post the Guardian carried. The lawsuits between operators and state attorneys general have multiplied in recent weeks, CoinDesk reported.
What does the CFTC want? Chair Michael Selig has been pushing to formally expand CFTC authority over the sector, a campaign that now has explicit presidential backing, per The Block's account of the Truth Social post. The CFTC's traditional commodities-and-derivatives remit is the legal hook for treating event contracts as federally regulated swaps, Cointelegraph reported.
Why does this matter for the industry? Federal pre-emption would shut down the patchwork of state-by-state enforcement that has chilled launches and frozen retail access in multiple jurisdictions, Decrypt reported. The "scum" language — directed at named state officials — is unusually direct for a presidential statement on a regulatory dispute, and signals the White House will treat state crackdowns on prediction markets as a political enemy, not a technical one.
