At least a dozen campaign staffers have been caught attempting to place bets on election outcomes through prediction markets, according to statements from Kalshi, the events exchange platform at the center of the controversy. The disclosures come as regulators and ethics watchdogs push for stronger safeguards against potential insider trading in political markets.
The incidents highlight a growing tension between the booming prediction market industry and concerns that people with access to nonpublic campaign information could profit by wagering on electoral outcomes before results become public.
What the Left Is Saying
Democratic lawmakers and government ethics advocates say the betting attempts underscore the need for immediate regulatory action. Senator Elizabeth Warren of Massachusetts said the activity represents a clear conflict of interest that existing securities laws should address.
"These aren't ordinary Americans making bets on elections — these are people with direct access to internal polling, strategy documents, and candidate health information," Warren said in a statement. "This is insider trading by another name."
Progressive advocacy groups have called on the Securities and Exchange Commission to extend existing market manipulation rules to cover political prediction contracts. The Revolving Door Project, which tracks executive branch appointments, argued that campaign staff positions create inherent informational advantages that could be exploited.
"When you work inside a campaign, you know things the public doesn't," said Jeff Hauser, the group's director. "Using that knowledge to place financial bets isn't just unethical — it may already be illegal under securities law."
What the Right Is Saying
Republican lawmakers and free-market advocates have pushed back against what they characterize as regulatory overreach. Senator JD Vance of Ohio argued that prediction markets serve an important function in aggregating information about electoral outcomes.
"Markets are intelligence mechanisms," Vance wrote on social media. "If campaign professionals want to express their views through a market, that's their prerogative."
Conservative commentators have also noted that Kalshi and similar platforms operate under existing CFTC guidance and have implemented their own compliance measures. The American Enterprise Institute's political economy team suggested that internal campaign policies — rather than federal regulation — offer the most appropriate remedy.
"Campaigns should enforce their own codes of conduct," said Michael S. Bernstein, a visiting fellow at AEI. "The solution isn't more Washington bureaucracy — it's holding staff accountable through existing employment relationships."
What the Numbers Show
Kalshi has reported blocking approximately 4,200 accounts it identified as connected to political campaigns since January 2026, according to data provided to reporters. The platform processes hundreds of thousands of contracts on election outcomes annually.
The Commodity Futures Trading Commission, which oversees event-based contracts, approved Kalshi's election markets in 2023 following a lengthy review process. CFTC Chair Rostin Behnam has said the agency is monitoring for potential manipulation but has not announced formal investigations related to campaign staff trading.
Prediction market aggregate data from July 2026 shows Trump leading Harris in national polling by approximately 3 percentage points, with state-by-state markets showing competitive races across Arizona, Georgia, Nevada, and Pennsylvania — four states widely viewed as decisive for the November outcome.
The Bottom Line
The Kalshi disclosures arrive as both major party campaigns are building out their compliance teams ahead of what is expected to be a highly contested election cycle. Campaign officials from both parties have insisted they were unaware of any coordinated efforts by staff to use prediction markets.
Regulators face pressure from two directions: progressive Democrats pushing for stricter oversight and some libertarian-leaning Republicans warning against rules that could chill legitimate political discourse. The SEC has not claimed explicit jurisdiction over Kalshi's contracts, while the CFTC has taken a wait-and-see approach pending further developments.
