Campaign Staffers Are Using Prediction Markets for Insider Gains — And the Feds Are Watching

A campaign staffer working on a statewide race in the South told NPR in May 2026 that they — along with fellow staffers — routinely placed bets on prediction markets before internal poll results went public. “Myself and others started placing bets before that poll came out,” the staffer said, speaking anonymously out of fear for their career. “And then, sure enough as soon as that poll came out, the stock went up and everybody made money.” That admission, reported by NPR and quickly circulated across the gambling industry press, put a blunt spotlight on a problem that regulators and prediction market platforms have been quietly grappling with for months: the integrity of political event contracts in an era where inside information is worth serious money.

How Political Event Contracts Work

If you are not already familiar with how prediction markets work, the basic mechanics are straightforward. Platforms like Kalshi and Polymarket allow traders to buy and sell event contracts — essentially binary bets on whether something will happen. On a political market, a contract might ask whether a given candidate will win a primary. The price of that contract reflects the market’s collective probability estimate. A contract priced at $0.20 implies a 20% chance of that outcome.

When meaningful new information enters the market — say, a poll showing a candidate has surged — traders adjust their positions and prices move accordingly. That is the system working as designed. The problem surfaces when one side of that trade already knows what the poll says before it is released. At that point, the market is not pricing in new information. It is pricing in a leak.

The Regulatory Gap That Made It Possible

The campaign staffer case lands in a legal gray zone that has frustrated regulators and legal analysts alike. The Commodity Futures Trading Commission oversees Kalshi and Polymarket as designated contract markets, and it does have anti-fraud authority under the Commodity Exchange Act. Specifically, CFTC Rule 180.1 — modeled on the SEC’s Rule 10b-5 — prohibits fraudulent and manipulative conduct in commodity markets, and the agency has used it in prior enforcement actions.

In February 2026, the CFTC’s Enforcement Division issued an advisory making clear it has “full authority to police illegal trading practices occurring on any DCM,” including prediction markets. Jeff Le Riche, a former CFTC trial attorney who spent 20 years at the agency focusing on insider trading cases, told NPR that campaign staffer election betting “could potentially be a violation” of the Commodity Exchange Act. He said the key factors — a duty of confidentiality, use of nonpublic material information, and clear awareness that the poll was inside information — are all arguably present.

But there is a catch. Former CFTC Commissioner Kristin Johnson said publicly that the commission lacks the experience and developed case law to effectively police election-related insider trading. “I don’t believe that the CFTC has developed experience and expertise in policing election positions,” Johnson said. The courts have not definitively ruled on how insider trading laws apply in this specific context, which leaves enforcement in uncertain territory.

What Kalshi and Polymarket Have Done About It

To their credit, the platforms have not ignored the problem. On March 23, 2026, both Kalshi and Polymarket announced updated rules aimed at closing insider trading loopholes. Polymarket revised its rulebook to prohibit trading on information that would “violate a preexisting duty or obligation of trust or confidence,” even if that information was obtained secondhand. It also expressly barred traders from wagering on events they can influence. Hours later, Kalshi announced new technological guardrails to prevent candidates from trading on their own campaigns and athletes from betting on their own sports.

Kalshi has backed those policy updates with real enforcement. In April 2026, the platform suspended and fined three political candidates for trading on their own races, including a Virginia Senate candidate and two state-level congressional hopefuls. Earlier, Kalshi had disciplined a YouTube editor who used advance knowledge of video content to profit on platform contracts. These were small-dollar cases, but Kalshi pursued them anyway — a deliberate signal about where the line is. You can read more in our Kalshi review about how the platform handles market integrity.

The campaign staffer situation is harder to crack. Kalshi and Polymarket were not contacted by the staffer’s campaign and had no formal relationship with them. The staffer was trading on Polymarket and PredictIt, not necessarily violating any explicit platform rule that covered their role. Whether their employment documents included a duty of confidentiality — which would be the linchpin of any CFTC enforcement action — is an open question. Polymarket did not respond to requests for comment about whether campaign staffer election trading violates its rules.

The Bigger Picture for Prediction Market Integrity

The CFTC’s first-ever insider trading complaint involving event contracts came in April 2026, when it charged an active-duty U.S. Army service member with using classified military intelligence to trade Polymarket contracts related to a military operation, allegedly generating more than $404,000 in profits. The Department of Justice filed a parallel criminal indictment the same day. That case was a watershed — it showed the CFTC is willing to bring enforcement actions under existing authority and that DOJ will follow when the facts warrant criminal charges.

Campaign staffers, however, occupy a different space than military personnel with security clearances. The legal framework for political insiders trading on polling data is murkier, and the Senate’s recent rule change prohibiting senators and their staff from trading on prediction markets does not extend to campaign staff. Several bipartisan bills have been introduced to close that gap — including Rep. Ritchie Torres’ Public Integrity in Financial Prediction Markets Act of 2026, which would apply STOCK Act-style restrictions to prediction market contracts — but none have become law.

For bettors who rely on Polymarket and similar platforms to reflect genuine market sentiment, this is a real problem. If campaign operatives are routinely positioning ahead of polls and internal data releases, retail traders are consistently on the wrong side of an information asymmetry. That erodes the core value proposition of prediction markets: that prices represent the true collective wisdom of the crowd, not the inside track of the well-connected. If you are still weighing whether these markets make sense for you, it is worth understanding the basics of whether prediction markets are legal before putting money to work.

The question heading into the 2026 midterm cycle is whether enforcement catches up to the behavior. The CFTC has the statutory tools, and both major platforms have tightened their rules. But until the legal landscape is clearer — and until political campaign culture treats prediction market trading as the ethical violation many observers believe it to be — the gap between what the rules say and what is actually happening on the ground will remain wide open.
