Campaign Staffers Traded Polls on Polymarket, Prompting Probe

An anonymous campaign staffer disclosed that they and colleagues routinely placed bets on Polymarket using internal polling data before those results became public. The staffer described participants earning several thousand dollars each campaign cycle. This account represents the third documented pattern tied to Polymarket in the past three months.

The staffer said the wagers were placed ahead of official poll releases and were based on nonpublic internal survey results. The trades occurred on Polymarket, a platform where users buy and sell contracts tied to political events. The staffer described the activity as recurring and profitable for those involved.

Other documented incidents in recent months include a roughly $553,000 bet connected to Iran and its supreme leader placed shortly before a foreign strike, and analysis attributing about $300,000 in profits to a trader who wagered on last-minute presidential pardons. On April 23, 2026, the Commodity Futures Trading Commission filed an event-contract insider-trading complaint charging Master Sergeant Gannon Ken Van Dyke with using classified information to trade on a contract tied to the capture of Venezuelan leader Nicolás Maduro. The Department of Justice filed a parallel five-count criminal indictment the same day.

Those enforcement actions invoked a Dodd-Frank provision that targets misuse of nonpublic government information. The CFTC has asserted jurisdiction over some event contracts and has brought civil and criminal cases tied to government insiders.

Legislative action so far has focused on government officials. On April 30, the Senate adopted Resolution 708 by unanimous consent, banning senators, officers and employees from trading on prediction markets. Representative Ritchie Torres introduced the Public Integrity in Financial Prediction Markets Act of 2026 on January 9 to bar federally elected officials, political appointees and executive branch employees from such trading. The bill has 30 House Democratic co-sponsors, including former Speaker Nancy Pelosi, and has not received Republican support. Those measures do not explicitly cover campaign staffers working on independent or state-level races.

In response to the recent account, seven House Democrats led by Representative Chris Pappas sent a letter to the House Oversight Committee requesting subpoenas and a formal investigation into trading on political event markets. The lawmakers asked the committee to examine whether campaign-linked trading produced unfair advantages and whether existing rules and enforcement tools are sufficient to deter or punish misuse of nonpublic campaign information.

Campaign organizations are not uniformly covered by federal statutes that bar trading by government officials, and many campaigns have not adopted formal employee trading policies. The regulatory status of event contracts remains unclear, with overlaps among commodities law, campaign finance rules and criminal statutes. Federal investigators and lawmakers will consider whether to pursue civil or criminal charges in cases tied to campaign workers and whether new or expanded legislation is needed to address trading based on nonpublic political information.
