A four-month-old regulator just made two of the biggest prediction-market names back out of Ireland — without going to court. That is a statement of intent.
Prediction markets Polymarket and Kalshi have restricted access in Ireland after the country’s new gambling regulator, GRAI, warned it would seek court orders. The regulator says the platforms require a licence to operate legally in Ireland. Both restricted the market rather than face enforcement, in one of GRAI’s first major actions since gaining powers in March.
- What GRAI Did

Prediction markets Polymarket and Kalshi have restricted access in Ireland under regulatory pressure. Ireland’s Gambling Regulatory Authority, GRAI, warned it would pursue court orders against them. According to the regulator, both platforms need a licence to operate legally in the country. Neither held one. Rather than face enforcement, both restricted Irish access. So the outcome came without a courtroom. GRAI confirmed it had engaged both operators over their unlicensed activity. However, the action is more significant than a single market withdrawal. It is one of the first major moves by a regulator that only gained its enforcement powers in March.
What GRAI Did
The regulator’s logic was straightforward. GRAI holds that prediction-market contracts on real-world events constitute gambling under Irish law. Offering them to Irish consumers therefore requires a licence. Neither Polymarket nor Kalshi held Irish authorisation. So both were operating unlawfully in the regulator’s view. GRAI said it contacted the operators about the activity. It warned that continued unlicensed operation could bring court orders compelling compliance. According to the regulator, both platforms then moved to restrict Irish users. That restriction is the practical result. Irish consumers can no longer freely access the markets. However, the source noted the compliance was not identical across both. The operators restricted access under the threat rather than conceding the underlying legal question. So the classification dispute itself remains unresolved, even as access ends. The same core question runs through our report on the Dutch KSA’s Polymarket ruling.
Why Prediction Markets Keep Losing These Fights
The pattern is now familiar across jurisdictions. Prediction markets argue they list financial or event contracts, not gambling. Regulators keep reaching the opposite conclusion. In Ireland, GRAI treated the contracts as gambling requiring a licence. The Dutch regulator took a similar view of Polymarket. Several US states have moved against these platforms too. So the classification argument is losing repeatedly outside the US federal framework. That consistency is the story. A prediction market on who wins an election looks, to many regulators, like a bet on an outcome. However, the operators have a real argument in their favour. Under US law, some of these contracts fall under federal commodities regulation, not state gambling law. That distinction does not travel. Ireland applies Irish gambling law, and the US commodities framework carries no weight there. As a result, a platform lawful in one regime can be unlawful in another. Trade coverage of prediction-market enforcement, including AGBrief, tracks these cases. The US front features in our report on Google’s prediction-market ad ban.
A New Regulator Flexes Early
The bigger signal is about GRAI itself. Ireland’s Gambling Regulatory Authority is new. It only received its enforcement powers in March 2026. So this is an early demonstration of what it intends to do with them. Making two prominent international operators withdraw, without a court battle, is a strong opening. It tells the wider market that GRAI will act on unlicensed activity. The choice of target matters too. Polymarket and Kalshi are among the most visible names in prediction markets. A new regulator taking them on signals it will not shy from large or novel operators. However, the restraint is also notable. GRAI secured compliance through a warning, not a prolonged legal fight. That is an efficient use of a young regulator’s resources. According to the regulator, it will continue engaging operators offering unlicensed gambling to Irish consumers. So this is likely a template rather than a one-off.

Frequently Asked Questions
Why did Polymarket and Kalshi restrict Ireland?
Ireland’s Gambling Regulatory Authority, GRAI, warned it would seek court orders because the platforms offered unlicensed gambling. GRAI treats prediction-market contracts as gambling requiring an Irish licence. Rather than face enforcement, both operators restricted Irish access. The underlying classification dispute remains unresolved despite the withdrawal.
What is GRAI?
GRAI is Ireland’s Gambling Regulatory Authority, a new body that received its enforcement powers in March 2026. Its action against Polymarket and Kalshi is among its first major moves. It oversees licensing and enforcement for gambling offered to Irish consumers, including newer products like prediction markets.
Are prediction markets considered gambling?
It depends on the jurisdiction. Operators argue their event contracts are financial products, and some fall under US commodities regulation. However, Ireland, the Netherlands, and several US states have treated them as gambling. National gambling law does not defer to the US classification, so the same platform can be legal in one country and not another.
Did GRAI take the operators to court?
No. GRAI warned it would seek court orders if the platforms continued unlicensed operation, but both restricted Irish access before that step. The outcome came through a compliance threat rather than litigation, an efficient early result for a regulator that only gained enforcement powers in March 2026.
How does this compare to other countries?
Regulators are using different tools toward the same end. The Netherlands issued a formal sanction against Polymarket, Google banned prediction-market ads in several US states, and US tribes and states have sued operators. Ireland used a court-order threat to secure voluntary withdrawal, all reflecting a shared view that the contracts are gambling.
Can Irish users still access the platforms?
Both Polymarket and Kalshi have restricted access for Irish users following GRAI’s intervention. Irish consumers can no longer freely use the markets. The operators restricted access under the threat of enforcement rather than conceding the legal question, so the position could change if the classification is challenged.
