Polymarket Plans Legal Challenge After France Blocks Access

France's gambling regulator has ordered internet service providers to block Polymarket, the crypto-native prediction market platform, just days before the World Cup final. The Autorité Nationale des Jeux (ANJ) issued the block on July 16, citing the platform's unlicensed status in the country. Polymarket says it will mount a legal challenge, arguing that French authorities have mischaracterized the service as a gambling platform rather than an information tool.

The block comes after Polymarket recorded 578,000 visits from France in June alone, making it a meaningful presence in the French market. The ANJ's timing, just ahead of one of the year's biggest sporting events, suggests regulators were concerned about unregulated betting activity during the World Cup final. Yet the selective nature of the enforcement raises questions about regulatory consistency: Kalshi, a competing event-based prediction market, was not blocked despite offering similar functionality.

Polymarket expressed surprise at being categorized as an unlicensed gambling operation. The company characterized itself as an information source and suggested the ANJ had misunderstood its business model. The platform operates on Polygon, an Ethereum layer-2 network, and allows users worldwide to trade contracts tied to real-world events like elections, sports outcomes, and economic data. Unlike traditional betting platforms, prediction markets function as price-discovery mechanisms where contract prices reflect aggregate market expectations about future events.

The distinction matters legally. Prediction markets argue they serve an informational purpose similar to financial derivatives or futures markets, which are regulated differently than gambling in many jurisdictions. France's regulator, however, appears to have concluded that Polymarket's user experience and market structure constitute gambling without proper licensing. The ANJ did not publicly explain why Kalshi, which offers functionally similar services, escaped the same enforcement action.

This move represents an escalation in European regulatory pressure on crypto-native platforms. France has long maintained strict oversight of betting and gaming services, with the ANJ wielding considerable power to block or restrict access to platforms deemed non-compliant. The broader pattern suggests European regulators are increasingly willing to order ISP-level blocks against crypto platforms while sometimes exempting traditional finance competitors offering analogous services. Polymarket's legal challenge will likely hinge on whether French courts view prediction markets as financial instruments subject to different regulatory frameworks, or as gambling services properly subject to ANJ jurisdiction.

The outcome could reshape how prediction markets operate across Europe. If Polymarket prevails, it may establish precedent that these platforms warrant lighter-touch regulation than traditional gambling. If the ANJ's block survives legal scrutiny, other European regulators may adopt similar enforcement tactics. French users attempting to access Polymarket will encounter blocks at the ISP level, though VPNs and other technical workarounds remain available. The legal battle is expected to take months, with Polymarket's arguments likely focusing on the platform's informational value and the inconsistent treatment of competing services.
