Developing The First Federal Prediction-Market Bill of the Cycle Does Not Touch the Exchanges. It Goes After the Candidates, Which Is a Concession Nobody Has Noticed

Laurie Buckhout bought less than $1,000 of contracts on her own congressional race. Kalshi's compliance department found them, fined her $2,589.96 — more than the position was worth — and suspended her for three years under rule 5.17(z), which bars anyone with direct influence over an outcome from trading it. She did not contest it. "I bet on myself. Literally," she told reporters. "It was a dumb mistake, and as soon as I learned there was an issue, I worked to make it right."

On Monday her opponent introduced a federal bill about it.

Don Davis holds North Carolina's 1st District and Buckhout is the Republican trying to take it from him in four weeks. His No Betting on Your Own Race Act would bar federal candidates, their spouses, their dependent children and their authorized campaign committees from buying, selling, acquiring, disposing of or holding any contract tied to the candidate's own election. It reaches indirect trades too: directing someone else to buy, or knowingly funding the purchase. The penalty is a civil fine of $10,000 or three times the net financial gain, whichever is larger. The Federal Election Commission would enforce it and would have to publish a machine-readable list of federal candidates, refreshed weekly, so an exchange could check a name against it.

The timing is as transparent as it looks. That is not the interesting part.

What the bill quietly assumes

Every significant piece of prediction-market law in 2026 has been an argument about whether these venues may exist. Nevada won in the Ninth Circuit on August 28, where the panel held that the substance of Kalshi's sports event contracts is gambling no matter what the exchange calls them, splitting with the Third Circuit, which had gone the other way on New Jersey. Ohio sent cease-and-desists to ten operators last week. More than a dozen states have active suits. The whole fight is over the legality of the counter.

Davis's bill does not join that fight. It takes for granted that a federal candidate can go to a legal American exchange and find a liquid market in her own election, and it legislates about what she may do when she gets there. The conduct is the target. The venue is furniture.

That is a concession, and it is the first one Congress has made in this direction. You cannot write a statute requiring the FEC to maintain a weekly candidate feed for the exchanges to screen against unless you have decided the exchanges are going to be there next year. The bill's machinery only makes sense in a world where election contracts are a permanent feature of American markets. Roughly $2 billion of US election trades have cleared this year — $1.31 billion on Kalshi across 1,322 markets since January, $632.4 million on Polymarket across 47 since April. Kalshi's chief executive, Tarek Mansour, says election volume has grown six times faster than football. His head of growth talks about $10 billion in 2028.

Whether Davis intended that concession is unknowable and mostly beside the point. Bills are read by their text.

The best argument against the bill, which is a real one

Here it is at full strength: this is redundant theatre. Kalshi's own enforcement arm caught Buckhout without a subpoena, a warrant or a single federal dollar. It has caught others. In April it published a batch — Matt Klein, a Minnesota state senator running for a House seat, $539 and five years; Ezekiel Enriquez, a House candidate, $784 and five years; Mark Moran, a Virginia Senate candidate, $6,229 plus forfeiture of his profit and five years, with the exchange noting he had initially declined to cooperate. George Santos drew a lifetime ban and a $71,356 fine in the same programme for not cooperating at all. Bobby DeNault, who runs enforcement there, put the standard plainly: "no matter how small the size of the trade, any trade that is found to have violated our exchange rules will be punished."

By that account, self-regulation worked five times out of five before Congress noticed. And the member introducing the fix is running against one of the five. If you wanted a clean case study in a private surveillance function outperforming a public one, this is it, and Davis has produced a press release instead of a gap analysis.

We think that argument is wrong, for three reasons that are about structure rather than motive.

First, a rulebook binds only the people who sign it. Rule 5.17(z) is a term of service at one designated contract market. It does not reach Polymarket's US exchange, it does not reach the next venue to get a licence, and it has no purchase whatsoever offshore. A candidate who reads about Buckhout learns exactly one lesson: do not do it on Kalshi.

Second, the sanctions are not deterrents in the currency candidates deal in. A House campaign in a competitive district spends millions. A $2,589.96 fine is a line item. The thing that actually hurt was the three-year ban and the news story in her district — and the ban is the one remedy Davis's bill does not contain. Under the statute as described, a candidate who pays $10,000 keeps her account. The exchange's penalty bites; the government's does not. That is backwards, and it is fixable in a sentence of drafting.

Third, and most important: by DeNault's own account, none of these cases were referred to the CFTC or the Justice Department. Set aside whether they should have been. The consequence is that trading on non-public information about a federal election, by the person generating that information, has so far produced no public enforcement record at all — no docket, no findings a voter can read, no process anyone outside the company can audit. An exchange investigating its own liquidity providers has an obvious interest in a quiet resolution, and we have only its summary of what it found. That is not an accusation of bad faith. It is a description of why self-reporting is a floor and not a ceiling.

What we do not know

Quite a lot. The press release names no bill number and no cosponsors, and we could not find either. A minority-party member introducing a bill four weeks before an election, aimed at conduct by his own opponent, is not a bill with a markup in its future; the honest read is that this is a message that will have to be reintroduced in the next Congress by someone else to go anywhere. We also do not know how the FEC would actually administer it. The commission is built to tie — six seats, no more than three from one party, four votes to act — and handing it a novel financial-conduct docket is a choice whose consequences depend entirely on a composition we cannot predict. The bill is silent on whether an exchange that fails to screen against the candidate feed bears any duty at all, which is the obvious place to put a compliance obligation and the place this draft leaves empty.

One more thing the bill gets right, and it deserves saying because we spend most of our time arguing the other way. Davis's comparison is the correct one: "We don't want our athletes to bet on their games. A candidate running for federal elected office should be treated exactly the same." Insider trading rules in event markets are not an attack on event markets. They are the thing that makes an event market a market rather than a mark. Kalshi did $18.37 billion of volume in the single week ending October 4, $11.82 billion of it in multi-leg exotics. A venue at that scale cannot be the only auditor of whether the people who determine its outcomes are trading them.

We have argued against criminalising federally licensed exchanges and we are arguing here for a narrow federal rule that would constrain their users. Readers should weigh both positions against our commercial interests.
