The prediction market landscape is witnessing a sharp escalation in tension. Industry leaders Polymarket and Kalshi are locked in a public dispute over regulatory compliance, user verification, and offshore operations.
The KYC Rumor and Polymarket’s Swift Denial
Recent media reports suggested that Polymarket, which operates under a dual-structure model, was preparing to roll out mandatory identity verification (KYC) checks. The move was reportedly designed to prevent users from bypassing its geofencing restrictions via Virtual Private Networks (VPNs). Additionally, reports claimed that verified users would receive exclusive perks, including direct co-location to minimize trading latency.
However, Josh Stevens, VP of Engineering at Polymarket, firmly denied these claims. He clarified that the verification features spotted by users are strictly tied to a new product currently in its beta testing phase.
“No KYC is being added to any part of existing polymarket.com with this launch. Once this product is out of beta no KYC will be required to use it.”
Kalshi Fires Back: Allegations of Sanction Evasion
The denial did not sit well with competitor Kalshi, a fully regulated U.S. prediction market. Robert J. DeNault, Kalshi’s Head of Enforcement, launched a scathing critique against Polymarket’s compliance framework and its offshore operational model.
DeNault alleged that individuals from sanctioned nations, including Iran and Russia, are actively trading on the platform. He further claimed that Polymarket had been shipping promotional merchandise to a user in Moscow to recruit more Russian traders.
“Enough is enough… If Polymarket is serious about stopping this, either bring all operations into compliance (which starts with KYC) or shut down the offshore exchange. What exists now is not a safe or fair platform to offer prediction markets.”
Compliance Comparison:
- Kalshi: CFTC-regulated, mandatory KYC, utilizes the “Poirot” active surveillance system to detect insider trading.
- Polymarket: Offshore/hybrid model, geofences U.S. IP addresses, does not require KYC for its main platform.
Targeting Insider Trading and Facing Congressional Scrutiny
Both platforms are simultaneously upgrading their internal controls to combat insider trading. Kalshi revamped its anti-insider trading protocols ahead of the Super Bowl, deploying its proprietary Poirot surveillance system and appointing top executives to oversee enforcement. Meanwhile, Polymarket introduced an updated ruleset specifically designed to flag and restrict insider trading activities.
These self-regulatory efforts come at a critical time. Rep. James Comer, Chairman of the House Committee on Oversight and Government Reform, officially launched a probe into both Kalshi and Polymarket. The committee has dispatched letters requesting comprehensive data on their user identification processes and insider trading mitigation strategies.
