Polymarket is reachable from the Czech Republic — the platform does not geoblock Czech IP addresses. The country has a notable crypto ecosystem anchored by Europe-based exchanges and a 2025 tax reform that is among the most crypto-friendly in the EU, exempting long-term holders. Here’s what Czech users need to know about using Polymarket.
Current Status: Blocked (Government ISP Block)
Polymarket is not on Polymarket’s own geoblocked countries list — the block is imposed by the Czech state, not by the platform. In July 2026 the Czech Ministry of Finance added Polymarket to its list of unauthorized internet games and ordered internet service providers (ISPs) to block the domain within 15 days.
This is a government/ISP-imposed block, not a Polymarket geoblock — the platform itself may still serve the site, and users have reported reaching it by switching DNS or using a VPN. Access can vary by provider and may change over time.
The Czech Republic has a moderate and active crypto community, with Europe-friendly exchanges and a tax reform effective from 2025 that exempts long-held crypto from personal income tax — a meaningful advantage for buy-and-hold users.
The Legal Landscape
The Gambling Act (Act No. 186/2016 Coll.)
Gambling and betting in the Czech Republic are regulated by the Gambling Act (Act No. 186/2016 Coll.), in force since 1 January 2017. The act imposes a structured licensing model:
- Ministry of Finance of the Czech Republic is the licensing and supervisory authority
- Internet games and technical games are a regulated, licenseable activity
- Operating without a license is unlawful, and regulators can list unauthorized operators
Prediction markets are not a named category in the Gambling Act. The Ministry of Finance has taken the position that an unlicensed platform offering event-based betting qualifies as an unauthorized game — which is the basis for its July 2026 action against Polymarket.
EU MiCA and the Czech National Bank
On crypto-assets, the Czech Republic applies the EU’s Markets in Crypto-Assets Regulation (MiCA), which has been in full effect across the EU since 30 December 2024:
- Czech National Bank (CNB) is the designated national supervisory authority for crypto-asset service providers (CASPs)
- CNB issued its first authorizations under MiCA in February 2026
- A Czech digital finance act aligns national rules with MiCA and its supporting regulations (Travel Rule, DORA)
MiCA governs service providers (exchanges, custodians, issuers) rather than individual users transacting on overseas platforms. Uses of Polymarket by private individuals fall outside the MiCA licensing scope, though the underlying betting activity is assessed under the Gambling Act.
Where Prediction Markets Sit
Crypto-based prediction market platforms sit in an unregulated gap between the Gambling Act (which doesn’t name them) and MiCA (which governs providers, not users). The Ministry of Finance’s reading places Polymarket-style platforms under the gambling framework as unauthorized operators. Individual users are not directly prosecuted for trading, and there is no record of enforcement against Czech Polymarket users.
How to Deposit from Czech Republic
Czech users have solid on-ramp options, including a homegrown exchange built for the local market.
Step 1: Buy USDC on a Local Exchange
| Exchange | CZK Bank Transfer | Card Payments | Notes |
|---|---|---|---|
| Coinmate | Yes | Yes | Czech-founded exchange since 2014; strong CZK support; the largest Czech exchange |
| Binance | Yes (via P2P/cards) | Yes | Global leader; CZK pairs and fiat options |
| OKX | Yes | Yes | Low fees and broad CZK/P2P support |
Deposit Methods Explained
CZK bank transfer (domestic/SEPA): Most Czech-friendly exchanges accept CZK deposits via domestic bank transfer or the SEPA system. Coinmate is designed around CZK and is the most straightforward option for Czech users. This is the recommended deposit method.
Card payments: You can also buy crypto directly with a debit/credit card, though fees are typically higher than a bank transfer. This is convenient for smaller amounts.
Step 2: Transfer USDC to Polymarket
- Go to Deposit on Polymarket
- Select Use Crypto and copy your deposit address
- Send USDC from your exchange to the Polymarket address
- Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Tax Implications
The Czech Republic introduced notably crypto-friendly tax rules effective from 2025, governed by the Income Tax Act (Section 10) for individuals.
The 3-Year Time Test
Gains from crypto you held for more than three years before selling are exempt from personal income tax, subject to a combined CZK 40 million gross-income limit per year (shared with certain other assets). This is the key exemption for long-term holders.
The Turnover Exemption
Even for crypto held less than three years, gains may be exempt if your annual gross income from crypto sales stays below a CZK 100,000 threshold. Below this value-test ceiling, no tax is due.
If You Pay
When the exemptions don’t apply, crypto gains are included in your taxable income and taxed at the standard progressive personal income tax rates:
| Tax Band | Rate |
|---|---|
| Standard band | 15% |
| High-income band (above the annual threshold) | 23% |
- Tax is generally calculated on the gain (difference between sale and acquisition value)
- You are responsible for self-reporting on your annual tax return — there is no withholding on overseas platform trades
- Keep detailed records of deposits, trades, withdrawals, and conversion rates
What You Don’t Pay
- No special crypto tax for long-term holders — the 3-year time test fully exempts qualifying gains (up to the cap)
- No additional crypto surcharge as such — general income tax rules apply
