Kalshi banned former Rep. George Santos for life on August 31, 2026, after the CFTC said he manipulated an event contract tied to his own attendance at the 2026 State of the Union address. The CFTC’s July 31 settlement order required Santos to disgorge $17,569.98, pay a $17,500 civil monetary penalty, and stay out of CFTC-regulated markets for three years.

What did George Santos do on Kalshi?

Santos traded a binary Kalshi contract asking whether he would attend the 2026 State of the Union address, an event whose outcome depended on his own conduct. According to the CFTC’s July 31, 2026 settlement order and press release 9276-26, Santos held a “Yes” position while making public statements that affected the market’s view of whether he would attend.

Between February 12 and February 25, 2026, Santos posted on X about the event, including asking followers what attire he should wear. The CFTC said those statements were false or misleading because they created the impression that he planned to attend, while Santos later did not attend. On the day of the address, he posted that he was “watching SOTU from an airport tv.”

The CFTC order said Santos made $17,569.98 from the trading. The settlement required disgorgement of that amount, plus a $17,500 civil monetary penalty, for a total monetary resolution of $35,069.98. Santos also agreed to a three-year ban from trading on or subject to the rules of any CFTC-registered entity. He settled without admitting or denying the findings, as is typical in many CFTC administrative settlements.

Kalshi’s own disciplinary action went further than the federal settlement. The exchange imposed a lifetime ban and a $71,356 penalty, citing market manipulation and failure to cooperate with its compliance review. Kalshi said the Santos action was its first lifetime ban.

Santos’s attorney, Joseph W. Murray, described the CFTC resolution as a practical decision to avoid litigation. Santos criticized Kalshi on X, calling it a gambling platform and questioning the company’s future. Those statements did not alter the CFTC order or Kalshi’s separate disciplinary penalty.

Who else did Kalshi sanction in August 2026?

Kalshi’s August 31 disciplinary notices also named other traders, though the Santos case drew the most attention because it overlapped with a CFTC settlement and involved a former member of Congress trading on an event he personally controlled.

Stephen Cloobeck received a three-year suspension and a $31,770 penalty after purchasing about $10,000 in contracts. Two other traders identified by Kalshi as Midgley and Buckhout each received three-year suspensions and smaller penalties after trading less than $1,000. Kalshi framed the actions as enforcement of its exchange rules against manipulative trading in event contracts.

The difference in sanctions matters for the industry. The CFTC order shows how federal anti-manipulation authority can apply to event contracts listed on a registered exchange. Kalshi’s penalties show how an exchange may also use its own rulebook to suspend or ban users, even when the federal remedy is narrower.

What has the CFTC said about manipulation in prediction markets?

The Santos settlement followed several CFTC statements and enforcement actions in 2026 addressing event-contract trading. On February 25, 2026, the CFTC’s Division of Enforcement announced an advisory through release 9185-26 warning that fraud, manipulation, disruptive trading, and misuse of material nonpublic information in event contracts can implicate the Commodity Exchange Act and CFTC regulations.

That February advisory did not create a new statute. It stated the Enforcement Division’s view that conduct in event-contract markets can fall within existing CFTC authority, including Section 6(c)(1) of the Commodity Exchange Act and Regulation 180.1. The distinction is important: the agency was signaling how it would police registered markets, not announcing that Congress had enacted a prediction-market-specific insider-trading law.

The CFTC later issued Staff Letter No. 26-08 on March 12, 2026, through the Division of Market Oversight. That letter addressed event contracts from a market-oversight perspective and was separate from the February 25 enforcement advisory. Together, the two documents show the agency using both enforcement and market-supervision channels as prediction markets expand beyond small retail political contracts.

The most serious 2026 enforcement action involving event contracts was not the Santos matter. In April, the CFTC filed a civil complaint in the Southern District of New York against Gannon Ken Van Dyke, docketed as No. 26-cv-3369. Federal prosecutors also filed a parallel criminal case in the same district, No. 26 Cr. 156. The CFTC alleged Van Dyke, an active-duty U.S. Army service member, misappropriated classified or sensitive nonpublic information about Operation Absolute Resolve, a Venezuelan political matter, and traded Polymarket contracts for profits exceeding $404,000.

The Van Dyke complaint cited Sections 4c(a)(3), 4c(a)(4), and 6(c)(1) of the Commodity Exchange Act. Section 4c(a)(4), often called the “Eddie Murphy Rule,” restricts trading based on certain misappropriated government information. That case sits outside Kalshi’s exchange discipline, but it gives the industry a federal example of how prosecutors and the CFTC may treat event-contract trading tied to government information.

How did Kalshi handle candidate trading cases earlier in 2026?

Kalshi separately announced disciplinary actions on April 22, 2026, against political candidates who traded on their own races. Those were exchange-level disciplinary actions, not jointly announced CFTC enforcement settlements.

Kalshi said Mark Moran, a Virginia Democratic primary candidate, was fined $6,229.30 and suspended for five years. Matt Klein, a Minnesota Democratic state senator running for Congress, paid $539.85 and received a five-year suspension. Ezekiel Enriquez, a Texas Republican primary candidate, was fined $784 and suspended for five years under Kalshi Exchange Rule 5.17(z).

The candidate cases and the Santos case share the same market-integrity problem: traders with control over, or privileged access to, the underlying event can distort prices that are supposed to aggregate dispersed information. The remedies differed because the Santos matter also produced a CFTC settlement order, while the April candidate actions were announced by Kalshi as internal exchange discipline.

What does the CFTC’s June 2026 proposed rule change?

The CFTC published a proposed rule in the Federal Register on June 12, 2026, listed as document 2026-11854 and 91 FR 35806. The proposal addressed event contracts under Rule 40.11 and Section 5c(c)(5)(C) of the Commodity Exchange Act. It was a proposed rule, not a final rule.

The proposal followed a March 2026 advance notice of proposed rulemaking that drew about 3,500 public comments, according to the Federal Register notice. The June proposal would require the CFTC to give prediction market exchanges a written determination identifying factors warranting review before blocking a contract, and it would give exchanges a formal opportunity to respond in writing.

On substance, the proposal would define when an event contract “involves” an enumerated activity that Congress identified as potentially contrary to the public interest. It also proposed regulatory definitions for public-interest factors and stated the CFTC’s preliminary view that Section 5c(c)(5)(C) does not authorize categorical public-interest determinations. That approach would narrow how the agency evaluates event contracts, but the proposal would still leave the CFTC with authority to review and prohibit specific contracts.

The Federal Register notice also discussed sports contracts. It indicated that some sports-related contracts, including those tied to officiating outcomes or player injuries, could raise public-interest concerns. The proposal did not amount to a blanket approval or ban for all sports markets.

The comment deadline for the June 12 proposal was July 27, 2026. With that deadline passed, the next regulatory step is for the CFTC to review the record and decide whether to finalize, revise, or withdraw the proposal.

How does this fit Kalshi’s broader legal position?

Kalshi entered 2026 after a major federal-court win over the CFTC on political event contracts. In the U.S. District Court for the District of Columbia, Kalshi challenged the CFTC’s earlier attempt to block its congressional-control contracts. The court granted summary judgment to Kalshi, finding that the contracts did not involve unlawful activity or gaming under the provision the CFTC invoked. The CFTC later dropped its appeal, and in 2026 withdrew its earlier proposed rule restricting event contracts.

That federal win did not end the industry’s legal exposure. State gambling regulators and attorneys general continued to challenge event-contract platforms, especially where contracts overlap with sports or elections. In March 2026, Arizona filed a 20-count criminal information against Kalshi alleging illegal gambling and election wagering. Kalshi and regulators have also fought in federal court over whether state gambling laws are preempted when applied to a federally designated contract market.

The preemption issue remains contested. On August 28, 2026, the Ninth Circuit rejected Kalshi’s preemption position for sports contracts, narrowing the argument that federal designation alone shields event contracts from state gambling enforcement. That decision makes the distinction between federal market oversight and state gambling law a central question for platforms, regulators, and institutional counterparties.

The Santos ban is therefore not an isolated discipline story. It gives the CFTC and Kalshi a concrete example of market manipulation in a high-profile event contract, just as regulators are deciding how much of the industry’s future rulebook should be written at the federal level. The dates now on the record are fixed: Santos settled with the CFTC on July 31, the proposed-rule comment period closed on July 27, and Kalshi imposed its lifetime ban on August 31.
