Czech Republic Blocks Polymarket as Unlicensed Gambling

The Czech Republic has become the latest European country to shut the door on Polymarket, after its finance ministry ordered internet providers to cut off access to the crypto-based prediction market and treat it as an unlicensed gambling operator.

The Ministry of Finance added Polymarket to its list of unauthorised online games on July 13, 2026 — the register the state uses to wall off betting sites that take money from Czech residents without a domestic licence. The operator had a short window to appeal the listing before it took effect, but the block now stands.

Landing on that list triggers a fixed sequence. Internet providers have 15 days to cut off the site once it is published, blocking it at least at the domain-name level, while payment firms are barred from moving money to or from the operator’s accounts. Providers that ignore the order face fines. It is the same machinery the Czech state already uses against unlicensed online casinos and sportsbooks — Polymarket is simply the highest-profile name yet to be caught by it.

Why the regulator calls it gambling

The reasoning is what makes the case notable. Czech authorities argue that Polymarket dresses betting up as finance: it presents itself as an investment tool, but for the user it works like a wager — money staked on an uncertain outcome, with “contract” standing in for “bet” and “return on investment” for “winnings.”

That framing matters because of how Polymarket is built. Launched in New York in 2020 and now domiciled in Panama, it runs on the Polygon blockchain and settles trades in the USDC stablecoin, and its international platform has historically let users connect a crypto wallet and trade without mandatory identity checks. To a gambling regulator, a service that takes largely anonymous money on the outcome of elections, sports and wars — with no licence, no age verification and no register of self-excluded players — reads close to a worst case.

Jan Řehola, who directs the Institute for Gambling Regulation, a Czech body that represents most of the country’s licensed operators, backed the ministry’s decision.

> “Prediction markets are not harmless technological novelties. They involve betting on real-world events, often without clear accountability to the state, without standard player-protection measures and without the rules that apply to legal gambling.”

His argument is not that innovation should be banned, but that the same obligations — player protection, anti-money-laundering checks, market supervision — should apply to anyone taking money on an outcome, whatever they call the product. The institute said it would keep examining whether other prediction-market platforms meet the Czech definition of illegal gambling, a signal that Polymarket may not be the last name added to the list. The pressure to act is domestic as well as ideological: by the institute’s own research, roughly 800,000 Czechs use unlicensed gambling sites, costing the state billions of korun a year.

A widening European crackdown

The Czech action fits a pattern that has spread across the continent in under two years. France was the first major market to force a geo-block, in late 2024; Spain ordered its providers to cut off Polymarket and rival Kalshi in May 2026; and Italy put Polymarket back on its blocked list in July 2026 after an earlier ban was lifted on appeal. Germany, Belgium, Poland, Portugal and Romania have taken similar steps, and outside Europe, Brazil, Australia and New Zealand have moved against the platform too. Almost every action rests on the same finding: a prediction market is gambling, gambling needs a licence, and Polymarket holds none in the markets shutting it out.

The timing sharpens the point. The Czech block lands during the 2026 World Cup, when sports contracts — the product regulators are most eager to police — draw heavy prediction-market volume.

Regulators also point to the integrity risks that licensed betting is built to catch. French investigators examined suspicious Polymarket positions tied to temperature readings near a Paris airport, where the measured result may have been physically manipulated to settle a market; in the United States, a service member was charged with trading on nonpublic government information about a military operation. Those are the scenarios — match-fixing, insider dealing, money laundering — that the licensing rules Polymarket has sidestepped are meant to police.

A divided map

The European bans sit awkwardly against how the same platform is treated elsewhere. In the United States, Polymarket now operates under federal oversight from the Commodity Futures Trading Commission, which regulates its contracts as financial products — even as states such as Nevada have gone to court to stop it from taking bets without a state gaming licence.

Europe is not entirely of one mind either. This month, Gibraltar went the opposite way, launching the world’s first standalone regime for prediction markets — regulating them as neither gambling nor a financial instrument, but as their own category. The split leaves Polymarket federally overseen in its home market, shut out of a growing share of Europe, and licensed as gambling almost nowhere its users actually trade. For a platform that has spent 2026 expanding its sports and political markets, each new name on a national blacklist narrows the ground it can defend by pointing to what it calls its product — and that is precisely the argument regulators keep rejecting.
