What did the CFTC publish on March 12, 2026?

Staff Letter 26-08, an advisory from the Division of Market Oversight that confirms the CFTC's exclusive jurisdiction over prediction markets and clarifies how Designated Contract Markets like Kalshi and Polymarket should self-certify event contracts before listing them. It signals new rulemaking is coming but, in the meantime, existing markets continue to operate normally.

What was the 2024 'Event Contracts' rule that the CFTC withdrew?

A Biden-era rule proposal that would have banned event contracts on 'gaming,' a category that explicitly included sports. If finalized, it would have pulled every NBA, NFL, MLB, and college contract from Kalshi. The CFTC formally withdrew it on February 4, 2026 (Press Release 9179-26).

Does the advisory affect US traders specifically?

Yes — it strengthens the legal basis for federal preemption, which means any state Attorney General would have a harder time forcing Kalshi or Polymarket to geofence the state. Federal regulators have not pursued enforcement actions against federally-regulated prediction markets, so the practical access for US traders remains unchanged but is now more durable.

Are sports contracts safe through 2026?

Almost certainly yes. The 2024 ban proposal is dead, and any new restrictive rulemaking takes 12-18 months to finalize. The earliest a sports-specific restriction could land would be late 2027.

What about election contracts?

Election contracts are the most likely target of any future restrictive rulemaking. The 2024 election cycle generated significant political backlash, and the new rulemaking expected in late 2026 may include election-specific carveouts. Sports, macro, and entertainment contracts are at much lower risk.

What's the insider-trading risk?

Senate Democrats sent the CFTC a letter on April 30, 2026 urging stricter enforcement on prediction-market insider trading, particularly on contracts tied to military, government, or sports outcomes where nonpublic information may exist. The CFTC has full authority to refer cases to DOJ. Don't trade on nonpublic information.

Where can I read the official text?

CFTC Press Release 9193-26 (March 12, 2026) and Staff Letter 26-08 are both available on cftc.gov. The February withdrawal is Press Release 9179-26.
