The Czech Republic has ordered internet service providers to block access to Polymarket, a decentralized prediction market platform, citing violations of the country's gambling laws. The move is one of the first direct state-level actions against a blockchain-based betting service in Europe.
What the order says
Czech authorities determined that Polymarket's operations constitute illegal gambling under national regulations. The platform lets users place bets on real-world events using cryptocurrency, without a central operator or traditional licensing. Regulators argue that such activities fall under existing gambling prohibitions, even when conducted through smart contracts and decentralized infrastructure.
The order targets ISPs rather than the platform itself, reflecting the difficulty of shutting down a decentralized network. By blocking domain names and IP addresses at the service provider level, the Czech government aims to prevent residents from accessing Polymarket's website and app.
Why decentralized platforms are hard to regulate
Polymarket runs on the Polygon blockchain and uses smart contracts to settle bets. There is no single company to fine or shut down. That makes enforcement tricky. Traditional gambling laws were written for centralized operators with physical premises or bank accounts. Decentralized platforms operate across borders, often with no clear legal entity in any jurisdiction.
The Czech action highlights a growing tension. European regulators are increasingly scrutinizing crypto-based prediction markets, but their tools are limited. Blocking websites is a blunt instrument — users can still access the platform via VPNs or decentralized domain systems. The effectiveness of the order remains uncertain.
What comes next
Polymarket has not publicly commented on the Czech order. The platform continues to operate globally, and it's unclear whether it will challenge the block or comply in some way. Other European countries may watch the Czech move closely. If similar actions follow, decentralized prediction markets could face a patchwork of bans across the EU.
For now, Czech users who try to visit Polymarket will likely see a block page from their ISP. Whether that stops betting or simply pushes it further into the shadows is an open question.
