The Gambling Regulatory Authority of Ireland (GRAI) has issued warning letters to prediction market operators, threatening High Court action if they do not block Irish users from accessing their platforms. According to GRAI head Anne Caulfield, the regulator is targeting sites that allow users to wager cryptocurrency on political events, financial fluctuations, and global news, citing concerns over unregulated betting and potential money laundering.
Regulatory Crackdown on Cryptocurrency Betting
Ireland’s gambling regulator is actively intervening to force prediction markets to geoblock Irish IP addresses. Anne Caulfield, speaking on RTÉ’s This Week programme, confirmed that the GRAI enforcement team has already successfully compelled one major platform to restrict access. A second operator is currently in the process of implementing similar measures.

The authority has made nearly 30 interventions to date, with the vast majority of sites withdrawing from the Irish market shortly after receiving notice. In some instances, operators restricted access within 35 minutes of the regulator’s intervention. If platforms refuse to comply, Caulfield stated the authority is prepared to seek High Court orders to block both site access and the associated funding channels.
Did you know?
Prediction markets often host “event contracts” on topics ranging from the outcome of local by-elections to speculative events like the existence of aliens or individual tweets from high-profile figures like Elon Musk.
The “Wild West” of Unregulated Digital Betting
The regulatory pressure follows heightened scrutiny from the Irish government regarding the influence of decentralized betting platforms. In May, Tánaiste and Finance Minister Simon Harris expressed “grave concerns” regarding the “Wild West” nature of these markets. Harris specifically highlighted the risks of money laundering and the secretive, unregulated manner in which cryptocurrency is used to place bets.
Government concern intensified after reports surfaced of approximately $1 million in bets placed on the Dublin Central by-election via the platform Polymarket. A significant portion of that volume was directed toward wagers on the defeat of specific candidates. While there was no suggestion of wrongdoing by any candidate, the scale of the activity triggered a government request for police and regulators to examine the platform’s operations.
Global Landscape for Prediction Markets
Prediction markets currently face a fragmented regulatory environment. While some platforms like Kalshi explicitly list 55 restricted countries in their membership agreements, others operate with varying degrees of compliance.
- Polymarket: Currently restricts users in over 30 countries, including the UK, France, Germany, Italy, Belgium, and Poland. It maintains specific compliance measures for its US operations.
- Kalshi: Prohibits Irish users from trading event contracts as part of its global membership compliance.

What happens if a site ignores a GRAI warning?
The regulator has confirmed it is prepared to go to the High Court to obtain blocking orders that would prevent Irish internet users from accessing the site and potentially cut off the financial infrastructure supporting the bets.
Are all prediction markets blocked in Ireland?
Not all sites are blocked, but the GRAI has confirmed it has already forced several to implement geoblocking. Users should expect continued enforcement actions as the regulator continues its review of the sector.
