CFTC and Kalshi Enforce Insider Rules on Event Contracts
CFTC amicus brief in a Polymarket case, a $172,000 Perez fine, and Kalshi’s ban of George Santos treat event contracts as markets with integrity rules.
The Commodity Futures Trading Commission and a regulated venue for event contracts used the same window to treat those products as markets with integrity rules, not as experiments.
Event contracts are derivatives that pay based on whether a stated real-world outcome occurs.
The CFTC filed an amicus brief — a court filing that states the agency’s legal view without making it a party — in a federal criminal case over alleged insider trading on Polymarket event contracts.
Separately, the agency fined former White House staffer Gabriel Perez $172,000 in a civil settlement tied to non-public information.
Kalshi permanently banned former U.S. Representative George Santos from trading on its platform, the venue’s first permanent ban, over State of the Union trading.
The people on the hook are traders with privileged access to outcomes, and the platforms that list contracts on those outcomes.
How large the trades were, and whether these steps bind larger venues, is not disclosed.
The Polymarket brief
The criminal case centers on a soldier accused of trading around information that was not public.
The CFTC regulates certain derivatives, including swaps — contracts that transfer risk tied to an underlying price or event.
The brief is the agency’s chance to tell a federal court how those Polymarket contracts sit inside that statute.
It is not a conviction.
It is not a ruling against Polymarket.
An amicus filing does not write a new rule for every event contract.
The court still has to decide the case on its own facts.
The Perez fine
The Perez matter is a civil settlement drawn from CFTC settlement materials, not a new criminal indictment.
The agency tied the $172,000 fine to trading connected to non-public information around event-market outcomes.
The size of Perez’s positions is not disclosed.
A consent fine of that amount does not classify every political or geopolitical contract.
It does show the CFTC treating privileged information in these markets as an integrity problem it will fine.
Money at risk here is the civil penalty itself, plus whatever trading profits the settlement materials do not itemize.
Kalshi’s Santos ban
Kalshi’s action is a platform ban, not a CFTC order.
Former Representative George Santos is permanently barred from trading on Kalshi.
The platform described it as its first permanent ban.
The stated basis is trading tied to the State of the Union.
Position size, profit, and the surveillance that led to the ban are not in the public materials attached to this note.
A venue can exclude a named user under its own rules even when no federal fine is attached.
Who is exposed
Individual traders with government, military, or other privileged access sit in the enforcement path.
Polymarket is the venue named in the criminal case’s fact pattern.
The CFTC brief is about the legal character of the contracts, not a finding that the platform itself traded.
Kalshi is enforcing its own market-integrity rules against a named former member of Congress.
Operators that list event contracts now have a public record of both a federal civil money penalty and a venue-level permanent exclusion for alleged use of non-public information.
Users of those markets are exposed if they trade on facts the public does not yet have.
Holders of the platforms’ tokens or equity are not the parties named in these three actions.
What remains unknown
The scale of trading in the Perez settlement and in the Santos activity has not been disclosed.
Whether these three actions set precedent for larger platforms is not settled.
An amicus brief does not bind other courts as a regulation would.
A $172,000 consent fine does not decide how every event contract should be classified.
A first platform ban does not tell other venues what their rulebooks must say.
Those questions remain with the courts, the CFTC’s next cases, and the platforms’ own surveillance choices.
