18 Oct 2026 Read update The Ministry of Finance added Kalshi.com to the List of Unauthorised Internet Games on 30 September 2026, with the ISP-blocking obligation under Sections 84d and 84e of Act No. 186/2016 Coll. taking effect on 15 October 2026. This follows the same statutory treatment applied to Polymarket in July 2026, establishing a repeated enforcement pattern against US-domiciled prediction-market platforms. The enabling Act is the instrument behind the power; the blacklist listing itself is an administrative application of that power rather than a new rule. The consistent application of this mechanism to a second platform within a single year signals a settled enforcement theory rather than an isolated action, creating accessory-liability exposure for Czech-facing payment processors or affiliate intermediaries servicing such platforms once listed. No criminal referral has been evidenced in connection with either listing; the mechanism as evidenced is administrative blocking under the unauthorised-games catalogue.

11 Oct 2026 Read update The Ministry of Finance added Kalshi.com to the List of Unauthorized Internet Games on 30 September 2026, with ISPs required to block the site within fifteen days of the prohibition order's publication, setting a block date of 15 October 2026. This follows the Ministry's identical action against Polymarket on 13 July 2026, with blocking effective from late July 2026. The two actions, roughly ten weeks apart against comparable outcome-based wagering platforms, establish a settled enforcement pattern applying the Gambling Act's blocking-register mechanism to prediction markets on a substance-over-form basis: as one commentator on the Kalshi action put it, what matters should not be the name of the product but its actual substance. The enabling statute behind this power is the Gambling Act (186/2016 Coll.) itself; a primary Ministry notice confirming the specifics of the order was not directly retrieved, so the facts rest on trade-press reporting of the Ministry's action rather than the Ministry's own published notice. The revocation and exclusion risk this pattern evidences is concentrated in the prediction-market and event-contract product class: any platform of this kind entering the Czech market should expect the same classification and blocking treatment already applied twice.

## Full section analysis

## Regulating bodies

Ministry of Finance, General Directorate of Customs, Customs Office, Municipalities and for AML also the Financial Analytical Office.

## Supervision by Regulator

Supervision is conducted via ongoing monitoring by the regulators and third party complains addressed to the regulator usually by players or operators. There is also a rigorous reporting regime in place established by Ministry’s Decree nr. 10/2019 Coll., on the method for gambling operators to notify and transmit information and transfer data, the scope of the data transfer and other technical parameters of data transfer. Through such reporting the regulators have ongoing access to the relevant data about the operations of licence holders.

## Enforcement against licensed operators

Enforcement action can be of administrative or criminal nature.

Administrative actions can be taken by authorities under the Gambling Act as well as various other acts. In this chapter we only address actions and sanctions which can be imposed by authorities under the Gambling Act, They are as follows:

Revocation of a licence

Administrative fines up to CZK 50,000,000

Injunction on the operation of the administrative offender

Either monitoring by the regulators or third-party complaints addressed to the regulator usually by one of the licensed operators.

Blocking of unauthorised online games - Internet connection providers on the territory of the Czech Republic are obliged to prevent access to any of the webpages and applications included in the list of the webpages with unauthorised online games (“Blacklist”). The Blacklist is maintained and entries in it decided on and made by the Ministry. It is available on the Ministry’s website and contains addresses of webpages offering (or facilitating offering) unlicensed online games and where available also details of payment accounts used for the purposes of operating unlicensed online games. The internet connection providers are obliged to prevent access to a webpage included in the List within 15 days from the publication date of the webpage on the Blacklist

Blocking of payments related to unauthorised online games - payment service providers are forbidden to execute payment transactions, whether credited or debited, to the payment accounts included on the Blacklist. They are obliged to comply with this prohibition within 15 days from the publication date of the payment account details on the Blacklist.
