Woofun AI reports that the Czech Republic has enforced a digital blockade against Polymarket, driven by the Czech Finance Ministry’s decision to classify the platform under the national Gambling Act. This regulatory action compels internet service providers (ISPs) to sever access to the site, marking a decisive enforcement step against unlicensed online gambling operators targeting domestic users.

The blacklist publication occurred on Monday, triggering a strict 15-day compliance window for ISPs to implement the technical restrictions. Polymarket, a prediction market where users trade contracts based on future event outcomes, had previously garnered significant attention during the 2024 US presidential election for its role in gauging political sentiment. Alongside rival Kalshi, the platform now faces mounting operational constraints as authorities scrutinize its business model.

Structurally, this move reflects a broader European Union regulatory consensus, with restrictions already active in France, Germany, Poland, Romania, and Spain. On July 3, the European Securities and Markets Authority (ESMA) issued a warning that many prediction market contracts likely fall under existing binary options prohibitions if they qualify as financial instruments. ESMA emphasized that marketing products as "event contracts" does not exempt firms from EU financial rules, noting that retail offerings may already violate the 2018 binary options ban while professional client services require authorization under MiFID II.

Per Woofun AI, similar regulatory pressures extend beyond Europe, with Australia, Indonesia, and Singapore imposing restrictions on prediction markets. In the United States, a jurisdictional conflict persists: state regulators allege that event contracts constitute illegal gambling, whereas the Commodity Futures Trading Commission asserts exclusive jurisdiction over these products as federally regulated derivatives. This divergence has led to conflicting court rulings and intensified calls for Congress to clarify the legal status of sports and political event contracts.
