Polymarket intensifies VPN crackdown, introduces voluntary ID checks amid legal scrutiny

Prediction market platform Polymarket has escalated its enforcement against users accessing the service through virtual private networks (VPNs), according to a report from The Information. The company has also blocked a number of accounts flagged as suspicious. In a parallel move, Polymarket has introduced an optional feature allowing users to voluntarily submit identity verification documents.

Background and regulatory context

Polymarket, a decentralized prediction market built on the Polygon blockchain, allows users to bet on the outcomes of real-world events—ranging from election results to sports matches. The platform has faced increasing scrutiny from U.S. regulators, particularly over potential violations of sanctions and anti-money laundering (AML) laws. The Commodity Futures Trading Commission (CFTC) has previously taken action against prediction markets operating without proper registration, and Polymarket settled with the CFTC in 2022 for $1.4 million over unregistered trading.

The tightening of VPN enforcement suggests the platform is proactively addressing concerns that users from sanctioned jurisdictions—such as Iran, North Korea, or Syria—may be bypassing geographic restrictions. VPNs are commonly used to mask a user’s location, making it difficult for platforms to enforce jurisdiction-based bans.

Details of the enforcement measures

According to The Information, Polymarket has deployed advanced detection methods to identify and block VPN traffic. Accounts exhibiting patterns consistent with VPN usage or other suspicious behavior have been suspended or restricted. The company has not publicly disclosed the exact number of accounts affected or the specific detection techniques used.

The new voluntary ID verification option allows users to submit government-issued identification documents. While not mandatory, this feature could serve as a trust signal for remaining users and potentially reduce the risk of fraudulent activity. It may also position Polymarket more favorably in ongoing discussions with regulators.

Implications for users and the market

For users who rely on VPNs for privacy or to access Polymarket from restricted regions, the crackdown may significantly limit their ability to participate. The voluntary ID verification, while optional, may create a two-tier system where verified users enjoy higher trust or access privileges in the future. This could influence user behavior and platform liquidity.

From a market perspective, Polymarket’s actions reflect a broader trend among crypto platforms moving toward compliance. Similar enforcement has been seen at centralized exchanges like Binance and Coinbase, which have tightened KYC (Know Your Customer) and geographic restrictions in response to regulatory pressure.

Conclusion

Polymarket’s simultaneous enforcement against VPN usage and introduction of optional ID verification represent a strategic effort to mitigate legal risks while maintaining user trust. As regulatory attention on prediction markets and decentralized finance continues to grow, these measures may become standard across the industry. Users should expect further compliance-driven changes as the platform navigates an increasingly complex legal landscape.
