France blocks access to crypto-based prediction market Polymarket over gambling concerns

France's National Gambling Authority has mandated internet service providers to block access to the crypto-based prediction market Polymarket. This decision comes in response to a significant rise in traffic from French users, which reached 578,000 visits. The regulator expressed concerns over illegal gambling practices and the safety of users engaging with the platform.

The order was issued on July 18, 2026, and was prompted by issues such as addictive mechanics and inadequate self-exclusion tools. Additionally, there were worries about the potential for market manipulation and significant user losses, which further fueled the need for regulatory intervention.

Polymarket's surge in traffic from French IP addresses has raised alarms among regulators, prompting a closer examination of the platform's operations. The National Gambling Authority's action reflects a broader trend of increasing scrutiny on online gambling and prediction markets across Europe. As digital gambling platforms gain popularity, authorities are tasked with ensuring consumer protection and maintaining market integrity.

The timing of this decision is crucial, as it coincides with a growing number of users engaging with crypto-based gambling platforms. The concerns raised by the regulator underscore the need for robust user checks and safeguards to prevent exploitation and protect vulnerable individuals.

The crackdown on Polymarket may signal a shift towards heightened regulatory oversight of crypto-based gambling platforms in Europe. As authorities continue to address concerns about user safety and market manipulation, platforms like Polymarket may need to adapt their operations to comply with legal standards. This evolving landscape could reshape the future of online prediction markets.

Looking ahead, potential legal challenges from Polymarket against the blocking order could emerge, as well as further regulatory actions in other European countries regarding online gambling. Stakeholders should remain vigilant and prepared for changes in the regulatory environment.
