Czech Republic Bans Polymarket, Orders ISP Blocking
Prague adds the crypto prediction market to its unauthorised list, mandating ISP-level enforcement.
The Czech Republic's gambling regulator added Polymarket to its list of unauthorised internet games this week, mandating ISP-level blocking of the prediction market platform across the country.
Why It Matters
Prediction markets occupy a regulatory grey zone in most European jurisdictions, and the Czech move sets a precedent for how authorities can act when operators decline to seek local licences. Jan Řehola, Director of the Institute for Gambling Regulation, stated plainly that player protection cannot bend to operator semantics — a direct signal that rebranding speculative contracts as "information markets" will not shield platforms from enforcement, per iGaming Business. For crypto-native prediction platforms operating across the EU, this raises the immediate question of whether complying with local licensing frameworks is cheaper than the reputational cost of outright bans. Operators that ignore the Czech precedent risk coordinated multi-market blocking as other regulators watch closely. Gambling always carries financial risk; unlicensed platforms add regulatory and fund-recovery risk on top.
Context
Polymarket is a decentralised, blockchain-based prediction market that allows users to trade outcome contracts on real-world events. As of July 2026, it operates without a European gambling licence, which Czech authorities argue places it squarely within the scope of unauthorised gaming under national law. ISP blocking is the Czech regulator's standard enforcement tool against unlicensed operators and has previously been applied to conventional offshore sportsbooks.
What's Next
The immediate milestone is enforcement at ISP level, which Czech law compels internet service providers to implement once a site lands on the unauthorised list. Polymarket has not publicly announced any intention to pursue Czech licensing or challenge the block as of this week.
