The move follows a similar decision against Polymarket back on July 13, 2026, when Czech authorities first added the prediction market to the same blacklist and gave ISPs 15 days to cut access. The Institute for Gambling Regulation, a trade group representing the country’s licensed gambling industry, had said at the time that Polymarket wouldn’t be an isolated case, and that other international platforms would keep facing the same enforcement under Czech gambling rules.
Jan Řehola, Director of the Institute for Gambling Regulation, commented:
“The inclusion of Kalshi shows that this approach is now being reflected in practice. What matters should not be the name of the product, but its actual substance. If a person puts money at risk on the uncertain outcome of a real-world event, it should not be possible to circumvent the rules simply by calling the bet a contract or a financial instrument.”
According to the decision, Kalshi also has 15 days to stop its operations, meaning that its platform will be unavailable to local users from October 15, 2026. Additionally, Czechia joins a growing list of countries restricting prediction markets, with Polymarket already facing limits or blocks in France, Germany, Poland, Romania, and Spain.
