Kalshi, one of the fastest-growing prediction market platforms, announced a major compliance upgrade on October 9, 2026. After recording more than $260 billion in wagers this year – a figure three times larger than the total volume handled in 2025, according to TickerTracker – the company hired former FBI special agent Sean Fern to build and run its inaugural anti-money-laundering (AML) team.
Fern arrives with a résumé that blends federal investigation work and courtroom experience. During his tenure with the FBI, he served on the International Corruption Squad and helped steer the probe into the multibillion-dollar bribery scandal linked to Malaysia’s sovereign wealth fund, widely known as the 1MDB case. After leaving the bureau, he spent several years as a federal prosecutor in Brooklyn, where he led the high-profile conviction of the wellness startup OneTaste for forced-labor conspiracies. In an interview with NPR, Fern said, “I want to make sure it’s a hard place to launder money or evade sanctions and commit fraud.”
What Fern will do at Kalshi
In his new role, Fern will act as a bridge between Kalshi’s senior management, law-enforcement agencies, and regulatory bodies. He explained that day-to-day AML work hinges on three pillars: customer identification tracing the origin of funds, and screening against sanctioned parties. “On a day-to-day basis, that involves knowing who our customers are, knowing where their money comes from, and making sure we aren’t doing business with sanctioned entities or parties,” Fern told NPR. Whenever a transaction raises a red flag, his team will flag it for further review and, when appropriate, refer the matter to authorities.
Regulatory pressure and industry context
Kalshi’s move comes amid a wave of scrutiny aimed at prediction-market operators. Federal prosecutors have recently settled with former U.S. Representative George Santos over alleged market manipulation, and a former U.S. Army soldier and a former Google employee were indicted for exploiting non-public information on rival platform Polymarket. In August, regulators fined Donald Trump’s former teleprompter operator for profiting from advance notice of presidential speeches on Kalshi’s “mention markets.” These actions highlight how regulators view the sector as a potential conduit for insider-trading and money-laundering.
Learning from the crypto-exchange playbook
The hiring mirrors strategies employed by cryptocurrency firms during the early 2020s boom. Exchanges such as Binance recruited former federal prosecutors and FBI agents to reinforce their compliance divisions, only to later see founder Changpeng Zhao plead guilty to money-laundering charges. Kalshi’s leadership says that bringing Fern on board is a proactive step to avoid a similar reputation-risk scenario. Elisabeth Diana, a Kalshi spokeswoman, noted, “We are growing up,” emphasizing that as banks, hedge funds, and other institutional investors begin to use the platform, robust AML safeguards become indispensable.
Looking ahead, Kalshi—valued at roughly $40 billion by PitchBook—expects to double its workforce within the next six months, expanding beyond its current 250 employees. The firm hopes that Fern’s expertise will not only protect the platform from illicit activity but also bolster confidence among regulators and institutional partners, positioning Kalshi for sustainable growth in an increasingly regulated market.
