Prediction-market regulation forks: Comer eyes official-bettor ban, Selig calls state cases 'egregious'

Prediction-market policy forked again on Nov 13, 2026. House Oversight Chair James Comer (R-Ky.) released the findings of his May 2026 probe and called on Congress to consider restricting — potentially banning — federal employees, lawmakers and staff from using prediction markets. The same morning at Cantor's Convergence conference, CFTC Chair Michael Selig called state criminal suits against prediction-market founders "really egregious." Primary trail: House Oversight committee release; The Block's coverage of the Comer findings and Selig remarks.

What Comer said

The House Oversight Committee's probe, launched in May 2026, reviewed about 1,700 pages of documents and held five bipartisan staff briefings on Kalshi and Polymarket. Comer's statement:

"Congress must consider additional reforms to prevent public corruption."

The committee's recommended direction is legislation restricting federal employees, lawmakers and congressional staff from trading on prediction-market platforms, up to an outright ban. The probe cites two active cases: an active-duty Army soldier accused of using inside information to bet, and a former White House teleprompter operator accused of the same. The Senate passed a resolution in April 2026 restricting its own members from participating in prediction markets; Comer's push would extend a similar bar to the executive branch and all congressional staff.

What Selig said

At Cantor Fitzgerald's Convergence conference the same morning, CFTC Chair Michael Selig addressed the parallel state-vs.-federal fight over prediction-market enforcement. His framing, per The Block:

"It is really egregious when you have certain states … throwing all their enforcement authority against the platforms."

Selig argued that disputes over whether an event contract is gambling or a CFTC-regulated derivative should not translate into criminal prosecution of platform founders. He said regulators and operators should be able to disagree without executives facing jail risk.

Selig's underlying legal argument — that designated contract markets listing CFTC-registered event contracts fall under the CFTC's exclusive jurisdiction — is the same one the agency has already pressed in court: the CFTC sued Utah on Oct 27, 2026 to block Utah's attempt to enforce its gambling statute against Kalshi, and The Block reports the CFTC and DOJ sued Arkansas AG Tim Griffin on Nov 12 targeting a parallel enforcement action. Louisiana filed the same day, targeting Kalshi, Polymarket, Robinhood and Coinbase.

Why the two tracks matter

The two tracks point in opposite directions, but both are about who gets to supervise prediction markets and who can go after whom:

• Comer's track narrows who may trade — tightening rules on federal insiders. It does not touch the platforms themselves and does not question CFTC jurisdiction.
• Selig's track narrows who may prosecute the platforms — defending CFTC exclusivity against state AGs who read event contracts as unlicensed gambling.

Both tracks move together when the platforms stay on the DCM/CFTC side of the line. They pull apart only on the specific question of whether state criminal suits against founders — not platforms — can continue while CFTC jurisdiction is being litigated.

What this changes for operators

• Kalshi, Polymarket, Crypto.com, Robinhood keep the CFTC's legal cover on federal preemption arguments. Selig made that clear publicly.
• Trading surfaces facing federal insiders will likely have to carry a new blocklist layer if the Comer proposal becomes law — the technical lift is modest (KYC + role attestation), the political lift much larger.
• State-by-state enforcement is the real operating risk for now: ~12 states and cities have active disputes with the platforms, per The Block's count of the ongoing landscape.

What to watch

1. Comer's draft text. A ban-vs.-limit draft will tell operators whether the intended rule covers trades, order entry by family members, or only accounts in the federal insider's own name.
2. The Arkansas and Louisiana dockets. The CFTC/DOJ injunction motions filed Nov 12 will test the exclusive-jurisdiction argument in two more circuits, after Utah.
3. How the lame-duck Senate handles both. The chamber is mid-lame-duck and the Trump SEC/CFTC nominees — including CFTC-bound Nathan Anonick and Matthew Rowland — are queued for the same Agriculture Committee that would carry CFTC-adjacent legislation. See our nominees note.

Context

The federal-state fault line on prediction markets has been widening all year: CFTC amicus filings against state attorneys general in multiple circuits, DCM-listed event contracts going live on major brokerage surfaces, and bipartisan congressional probes into insider trading by officials. Comer's push and Selig's defense are two sides of the same question — who supervises these markets, and what counts as a crime when the answer is contested. The answer is still being written in briefs, not statutes.
