French regulator blocks access to prediction markets

TLDR

Frances gambling regulator has ordered domestic internet providers to block access to crypto prediction platform Polymarket, treating its markets as illegal gambling under French law.

1. The National Gambling Authority (ANJ) instructed French ISPs to block Polymarkets website, citing unauthorized gambling, weak identity checks, and market integrity concerns.
2. This is part of a wider European push to treat crypto prediction markets as gambling or banned binary options, raising legal and access risk for similar platforms.
3. Crypto users should expect more geofencing, stricter KYC and location checks, and possible redesign of prediction products to comply with EU financial and gambling rules.

Deep Dive

1. What France Actually Did

Frances Autorit nationale des jeux (ANJ), the National Gambling Authority, has ordered internet service providers to block access to Polymarkets website for users in France, framing the platform as an illegal gambling service, according to ANJs statement and related reporting on Frances ISP block.

ANJ says prediction websites where users stake money on uncertain outcomes count as unauthorized gambling, and it has highlighted missing identity checks and concerns about possible manipulation of data sources such as weather sensors, as detailed in broader coverage of Frances order and scrutiny. Advertising or publicly sharing odds from such sites can carry fines up to 100,000 for French residents.

The ISP-level block targets French reach to Polymarkets front end. It does not shut down the platform globally or its underlying smart contracts, but it makes direct access from French IPs significantly harder.

2. Impact On Crypto Prediction Markets

Frances move sits within a growing European pattern. The Czech Republic has also ordered ISP blocks on Polymarket, and European regulators are exploring whether event-based contracts fall under MiFID II and existing bans on binary options, as noted in the wider European analysis of Frances ISP order.

For crypto prediction platforms, the key risk is that national authorities treat them primarily as gambling rather than as financial markets, allowing fast ISP blocks and criminal penalties without waiting for new securities or derivatives rules. That tension increases compliance uncertainty for cross-border, blockchain-based markets that rely on open access and pseudonymous participation.

3. What To Watch Next

Frances action could encourage more EU regulators to follow with ISP blocks, stricter enforcement against advertising odds, or formal guidance that event contracts are either gambling products or banned binary options for retail. ESMA has already signaled that some event contracts may qualify as financial instruments, which would invite securities-style oversight.

Platforms are likely to respond with tighter geofencing, stronger KYC and IP checks, and potentially redesigned products that avoid simple binary payoffs or focus on jurisdictions with clearer rules. Users should watch for:

1. New national announcements on prediction markets in the EU and UK.
2. Changes in platform terms, KYC, and regional restrictions.
3. Efforts to obtain licenses or reclassify contracts as financial products rather than gambling.

Conclusion

Frances ISP block on Polymarket shows how quickly national gambling rules can be used to restrict access to crypto prediction markets, even when the underlying protocol remains live. For crypto users and builders, the key implication is that regulatory risk now includes front-end access and local advertising rules, not just token classification, making jurisdiction choice, compliance design, and product structure increasingly important for event-trading platforms.
