Candidates Are Betting on Their Own Elections. Congress Just Noticed.

A battleground-district candidate was fined for trading contracts on her own race. Her opponent just filed the first federal bill to ban it — as America heads into its first prediction-market election.

Laurie Buckhout put money on herself to win a seat in Congress. Not in the metaphorical, campaign-trail sense — in the literal, order-book sense. The Republican nominee in North Carolina's 1st Congressional District traded contracts tied to her own race on Kalshi, the federally regulated prediction market. In August, the platform fined her just under $2,600 and suspended her for three years.

"I bet on myself. Literally," Buckhout said at the time. "It was a dumb mistake, and as soon as I learned there was an issue, I worked to make it right."

Her opponent saw something else. On Monday, Rep. Don Davis — the Democratic incumbent she is trying to unseat in what is widely seen as a tight battleground race — introduced the "No Betting on Your Own Race Act," a bill that would write into federal law a ban on candidates for federal office trading prediction-market contracts tied to their own elections. Violators would face a fine of $10,000 or three times their net gain from the trades, whichever is larger.

"We don't want our athletes to bet on their games," Davis said in a statement to CNBC, which first reported the bill, adding that a candidate for federal office "should be treated exactly the same and should not be allowed to trade on their own election."

The bill has almost no chance of passing before November 3 — the House and Senate aren't scheduled to meet again until after the midterms. But that's not really the point. The point is that America is about to run its first full national election with legal, regulated, mainstream betting markets attached to every competitive race — and the rulebook is being written mid-game.

The first prediction-market election

Election betting has existed at the margins for decades. What's different in 2026 is scale and legitimacy. Kalshi operates under Commodity Futures Trading Commission oversight. Polymarket has aggressively expanded its U.S. presence. Contract prices on House control, Senate control, and individual battleground races now get cited alongside — and sometimes instead of — traditional polling. Industry press reports that CBS News is incorporating Kalshi's market data directly into its midterm election coverage, and CNBC discloses a commercial relationship with the platform, including a minority investment.

That mainstreaming is exactly why the integrity question has gone from theoretical to urgent. A prediction market's entire value proposition is that prices aggregate dispersed information into an honest forecast. That proposition breaks if the people closest to the outcome — the candidates themselves — are trading the contract.

The rap sheet is already long

The Buckhout case was not an isolated incident. It was one of four enforcement actions Kalshi announced on a single day in August — and the mildest of them.

The headline case involved George Santos, the former New York congressman expelled from the House in 2023. According to Kalshi's disciplinary notice, Santos allegedly made more than $17,000 trading contracts on whether he would attend this year's State of the Union address — while making public statements about his plans, some of them false or misleading, in what the company described as an attempt to move the contract price. Days before the speech he posted that he would be there "in the gallery." On the day of the address, he posted that he was watching from an airport. Kalshi permanently banned him — the first permanent ban in the platform's history — and fined him $71,356. The CFTC had already ordered him in July to pay $35,000 and barred him from trading for three years.

Alongside Santos and Buckhout, Kalshi settled with a California gubernatorial candidate and a Maine gubernatorial hopeful over trades on their own races. That followed an April enforcement round in which the platform suspended and fined a U.S. Senate candidate and two House candidates for the same thing.

And the problem extends well beyond candidates:

In April, a U.S. Army Special Forces soldier was arrested on charges of using classified information to place Polymarket bets on the American military operation that captured Venezuelan leader Nicolás Maduro — netting roughly $400,000, according to the indictment.
A New York Times investigation in May found more than 80 Polymarket accounts making bets with suspicious characteristics, including positions opened hours before U.S. and Israeli strikes on Iran.
Rep. James Comer's House Oversight Committee opened an insider-trading investigation into Kalshi and Polymarket in May — nearly 1,000 documents and five briefings so far — and expanded it in late September to Hyperliquid, Crypto.com, and PredictIt's parent company. One letter cites a large leveraged short position opened on Hyperliquid within minutes of a then-nonpublic White House tariff decision in October 2025.

The pattern across all of it: the markets grew faster than the guardrails.

Congress banned itself, but not the challengers

Here's the asymmetry at the heart of the Davis bill. In April, the Senate voted unanimously to bar sitting senators and their staff from trading on prediction markets, effective immediately. But that rule has a hole in it: it applies to incumbents, not to the people running against them. A challenger for a Senate seat — someone with intimate, non-public knowledge of their own campaign's internal polling, fundraising, opposition research, and exit timing — can legally trade contracts on the race they are in. The House hasn't even passed its own version of the incumbent ban, though resolutions have been proposed.

Until now, enforcement has been almost entirely private. Kalshi polices its own order book, refers cases to regulators, and publishes disciplinary notices. That is genuinely more than nothing — it caught Santos and Buckhout. But a market structure in which the exchange is the primary cop, the fines are smaller than a used car, and the rules differ by platform is not a market structure built for the volume and attention these contracts now attract. Buckhout's penalty for trading her own race was less than $2,600. The bill her opponent just filed would make the floor $10,000. That gap is the entire policy debate in miniature.

Why this matters beyond the novelty

It's tempting to file this under political curiosities. That would miss what's actually happening: a new, CFTC-regulated asset class is being stress-tested in real time by the highest-stakes event on the American calendar, while the integrity framework around it is still under construction.

Three things are worth watching. First, whether the post-midterm Congress takes up the Davis bill or something broader — the athlete analogy is politically easy, and sports leagues solved this problem a century ago for exactly the reasons now on display. Second, how the CFTC handles the growing referral pipeline from the platforms themselves; the Santos case established that federal penalties can stack on top of private ones. Third, whether a high-profile integrity failure during this cycle — a candidate trade, a leak-driven price move on a battleground contract — becomes the industry's Black Sox moment. Prediction markets have spent two years winning the argument that they are information infrastructure, not gambling. One scandal at scale, during the one election everyone is watching, could undo that argument overnight.

The markets will probably call the midterms more accurately than the pollsters. The open question is whether anyone will trust the price.
