Kalshi has hired former FBI agent Sean Fern to lead its first dedicated anti-money laundering (AML) team, according to NPR.
The appointment gives the US prediction market operator a designated financial-crime lead as trading on event contracts draws closer attention from lawmakers and regulators.
The new team does not mark the start of Kalshi's AML checks. In February, the operator said it already used customer identity verification, AML screening and monitoring of trading activity.
NPR did not report Fern's formal job title, the size of his team or when the unit will be fully staffed.
Kalshi offers contracts tied to the outcome of events, including economic indicators and sports. Such markets have prompted questions about the identity of traders, the source of their funds and access to information that could affect contract prices.
A dedicated AML function gives Kalshi a specific team for financial-crime risks alongside its separate market-surveillance work.
In May, the House Committee on Oversight and Government Reform sought information from Kalshi and Polymarket about customer verification and suspicious trading.
The inquiry followed concerns about whether people with nonpublic information could profit from event contracts. It was a request for information, not a finding that either operator had breached the law.
Kalshi has also announced additional customer protection measures, expanded risk scoring and employment checks. In August, it said it planned to integrate Nasdaq's market-surveillance technology.
Separately, the Commodity Futures Trading Commission said Kalshi assisted an investigation that resulted in an insider-trading enforcement action against an individual.
Those measures address trading integrity and account risks, while Fern's team will focus on anti-money laundering controls.
NPR's report did not set out the team's reporting line or explain how it will coordinate with existing surveillance staff. That detail will matter as prediction markets grow and operators handle a wider range of events and customer activity.
The appointment signals an added layer of compliance staffing at Kalshi, although the operational scope remains undisclosed.
In May, Kalshi's appointment of Sudhir Jain as CCO and Head of Regulatory Affairs added a senior role overseeing its compliance division.
Before joining Kalshi, Fern worked as a federal prosecutor in Brooklyn and helped lead the 1MDB investigation as an FBI agent
