Polymarket is close-only in Ireland. If you’re a new visitor, you can’t start trading here — new positions cannot be opened on the Polymarket frontend, although the API itself is not restricted. This is a Polymarket compliance decision rather than a government-imposed block, and Irish IP addresses are not geoblocked. Ireland is a well-developed EU crypto market with solid SEPA deposit rails and clear capital gains tax treatment for crypto.

Current Status: Close-Only

Ireland is listed on Polymarket as close-only: existing Irish accounts can close the positions they already hold, but they cannot open new ones. The restriction applies to the Polymarket frontend — the underlying API is not restricted. For a new visitor, the practical result is that you can’t start trading from Ireland today, though there is no government block or ISP-level restriction in place.

Ireland itself has not ordered an ISP block, unlike some European jurisdictions. The status reflects Polymarket’s own compliance posture rather than active Irish regulatory enforcement against the platform.

Why Polymarket Restricts Ireland

Polymarket applies a close-only status to Ireland, meaning new trades cannot be opened on the frontend. The restriction is more limited than a full block — existing exposure can still be unwound rather than frozen.

Ireland’s regulatory environment for both gambling and crypto has been evolving rapidly, and prediction markets sit in a grey area between the two frameworks.

The Gambling Regulatory Authority of Ireland (GRAI)

Ireland’s gambling regulator is the Gambling Regulatory Authority of Ireland (GRAI), established under the Gambling Regulation Act 2024, which was enacted in October 2024. The GRAI replaces the previous regime and is responsible for licensing, regulating, and supervising gambling in Ireland, including online gambling.

  • The GRAI became operational with its licensing and regulatory powers coming into effect in early 2026
  • It focuses on public safety and wellbeing, with restrictions on gambling advertising, inducements, and credit-card use for gambling
  • Providers of gambling activities operating in Ireland must hold a GRAI licence

Prediction markets like Polymarket are not an explicitly licensed gambling product under the Gambling Regulation Act. Crypto-based, decentralized platforms fall outside the current licensing framework, leaving them in a regulatory grey area rather than a clearly authorised or clearly prohibited category.

Central Bank of Ireland and EU MiCA

Crypto activity in Ireland is regulated at the EU level under the Markets in Crypto-Assets Regulation (MiCAR), with the Central Bank of Ireland as the national competent authority. Ireland has chosen to follow EU developments rather than create a standalone domestic crypto regime.

Under MiCAR, crypto-asset service providers — including exchanges — must be authorised. Major exchanges such as Kraken have secured MiCA licences from the Central Bank of Ireland. However, MiCAR regulates crypto-assets and service providers; it does not specifically address prediction markets, which fall outside both the gambling and financial-instruments frameworks.

Where Prediction Markets Sit

Prediction markets in Ireland sit in an unregulated grey area between gambling law (GRAI, which targets licensed gambling operators) and financial/crypto law (Central Bank of Ireland under MiCA). There is no specific legal framework for event contracts or prediction markets, and no public enforcement action against individual Irish Polymarket users. This grey area is a key reason Polymarket approaches Ireland with its close-only compliance status.

How to Deposit from Ireland

Ireland has a well-developed crypto on-ramp ecosystem with reliable SEPA bank transfers. Note that because Ireland is close-only, a new visitor cannot open trades — these deposit steps apply mainly to existing account holders closing positions.

Step 1: Buy USDC on a Local Exchange

ExchangeSEPACardNotes
CoinbaseYesYesPopular in Ireland; strong EUR/USDC liquidity
KrakenYesYesMiCA-licensed via Central Bank of Ireland; low fees
BinanceYesYesGlobal leader; SEPA deposits available

Deposit Methods Explained

SEPA (Single Euro Payments Area): SEPA is the standard EU bank transfer system and the most reliable way to fund a crypto exchange from an Irish bank account in EUR. SEPA transfers to major exchanges are typically fast (often same-day or next-day) and low-cost. This is the recommended deposit method.

Card Payments: Most major exchanges accept debit/credit card purchases, which are instant but carry higher fees than SEPA transfers.

Step 2: Transfer USDC to Polymarket

  1. Go to Deposit on Polymarket
  2. Select Use Crypto and copy your deposit address
  3. Send USDC from your exchange to the Polymarket address
  4. Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Tax Implications

Crypto gains in Ireland are generally subject to Capital Gains Tax (CGT).

Capital Gains Tax (CGT)

The default treatment of profits from selling, trading, or spending crypto is a disposal for Capital Gains Tax purposes at 33%. Key points:

  • CGT applies to net gains (sale proceeds minus acquisition cost and allowable expenses)
  • There is an annual CGT exemption of €1,270 — gains below this threshold in a tax year are not taxable
  • Losses can be offset against gains in the same or future years

The Irish Revenue Commissioners (Revenue) take the position that most crypto disposals are capital gains. However, if your volume of trades is so high that it amounts to carrying on a trade, profits may instead be assessed as income under Income Tax rather than as capital gains — so frequent traders should confirm their status.

Reporting Requirements

  • Crypto gains must be reported to Revenue via your annual tax return
  • Capital gains are generally due within a set period after the tax year end; check current filing deadlines
  • There is no withholding tax on overseas platform trades — you are responsible for self-reporting
  • Keep detailed records of deposits, trades, withdrawals, and EUR values for each disposal

What You Don’t Pay

  • No VAT on buying or selling crypto for individuals
  • No wealth or net-worth tax on crypto holdings
  • Standard CGT rates apply — there is no specific crypto surcharge

Getting Started

If you already hold positions on Polymarket from Ireland and need to manage them, or you’re reviewing the platform:

  1. Sign up for Polymarket — under 2 minutes, no KYC required to view markets (Ireland is close-only, so new trades can’t be opened)
  2. Buy USDC on Coinbase or Kraken via SEPA — reliable EUR deposits
  3. Deposit or review funds — transfer USDC via Polygon
  4. Close out existing positions — as a close-only jurisdiction, unwind exposure you already hold
  5. Use limit orders to avoid taker fees — only taker orders pay fees on Polymarket

Frequently Asked Questions

Is Polymarket available in Ireland?
Not for new trading. Polymarket lists Ireland as close-only: existing Irish accounts can close their open positions, but new trades cannot be opened. The restriction applies to the Polymarket frontend — the API is not restricted. Ireland itself has not ordered an ISP block, and Polymarket does not geoblock Irish IP addresses.
Is Polymarket legal in Ireland?
There is a legal grey area. Ireland's new Gambling Regulatory Authority of Ireland (GRAI), established under the Gambling Regulation Act 2024, regulates licensed gambling and has been rolling out its licensing regime since early 2026. Prediction markets are not explicitly licensed, and crypto-based platforms like Polymarket fall outside the current gambling licensing framework. Crypto trading itself is regulated under EU MiCA by the Central Bank of Ireland, which does not treat prediction markets as its remit.
How do Irish users deposit on Polymarket?
Buy USDC on a crypto exchange like Coinbase, Kraken, or Binance using a SEPA bank transfer, then transfer the USDC to your Polymarket deposit address via the Polygon network. Keep in mind a new visitor cannot open trades from Ireland, so this matters mainly for closing out positions.
How is Polymarket taxed in Ireland?
Polymarket profits are treated as crypto gains, which are generally taxed as capital gains under Ireland's Capital Gains Tax (CGT) at 33%, with an annual exemption of €1,270. Keep records of all trades and report gains to Revenue on your annual tax return. If trading is so frequent it amounts to a trade, profits may instead be treated as income and taxed under Income Tax, so seek advice for active traders.
Can I deposit on Polymarket using SEPA or an Irish bank?
Not directly. You fund a crypto exchange with EUR via SEPA (the standard Irish/EU bank transfer system), buy USDC on that exchange, and then transfer the USDC to Polymarket. SEPA transfers to major exchanges are typically fast and low-cost.
