Is Polymarket Legal in Portugal?
Polymarket is currently accessible from Portugal. There is no specific Portuguese law that prohibits the use of blockchain-based prediction markets. Portugal has been known as one of Europe's most crypto-friendly countries, though recent tax changes have somewhat altered this reputation.
For a complete overview of Polymarket's legality across all countries, see our full country guide.
Portuguese Regulations on Prediction Markets
Portugal's regulatory environment involves several key authorities:
CMVM (Comissão do Mercado de Valores Mobiliários) — Portugal's securities market regulator oversees financial instruments and investment activities. The CMVM has not issued specific guidance on prediction markets. Polymarket is not registered with the CMVM.
SRIJ (Serviço de Regulação e Inspeção de Jogos) — Portugal's gambling regulator licenses and oversees online gambling operators. The SRIJ requires licenses for operators offering gambling services to Portuguese residents. While prediction markets share characteristics with betting, the SRIJ has not specifically classified them.
Bank of Portugal — The central bank has issued warnings about crypto risks but has maintained a relatively neutral stance compared to some European counterparts.
Crypto taxation changes — Portugal introduced crypto capital gains tax in 2023, ending its previous zero-tax policy on crypto. Short-term crypto gains (held less than one year) are now taxed at 28%. This change reflects a broader trend toward formalizing crypto regulation.
EU MiCA — As an EU member, Portugal is implementing MiCA regulations, which will create a more structured framework for crypto-related activities.
Portugal's tech-friendly culture and its history of crypto-friendly policies make it a relatively favorable jurisdiction for prediction market users.
How to Access Polymarket from Portugal
Portuguese users can access Polymarket without barriers:
- Visit Polymarket.com — no geo-restrictions for Portugal.
- Register with your email or a crypto wallet.
- Verify your identity with your Cartão de Cidadão or passport.
- Deposit USDC and start trading.
Risks and Considerations for Portuguese Users
Tax obligations — Since 2023, Portugal taxes short-term crypto gains at 28%. Crypto held for more than 365 days may qualify for exemption. Prediction market profits from short-term trading are likely subject to this tax. Report all gains to the Autoridade Tributária and consult a Portuguese tax advisor.
No regulatory protection — Polymarket is not regulated by the CMVM or SRIJ. Portuguese users have no access to local consumer protection or dispute resolution mechanisms for this platform.
SRIJ licensing requirements — The SRIJ could potentially classify prediction markets as gambling, which would require operators to hold a Portuguese license. This could lead to access restrictions in the future.
Platform and smart contract risk — Funds on Polymarket are held in blockchain smart contracts, not in regulated accounts. Users bear full risk of any technical issues.
