GRAI Confirms Prediction Markets Stirring Trouble in Ireland

Key Points

• GRAI CEO Anne Marie Caulfield confirmed the regulator could pursue High Court blocking orders against one of the world’s largest prediction market platforms still targeting Irish consumers without a licence.
• Both Polymarket and Kalshi restricted access to Irish users as of 21 July 2026, with a second platform geoblock confirmed on that same date following direct GRAI intervention.
• Nine European countries have signed a collective agreement against prediction markets, while Gibraltar moved in the opposite direction, launching the world’s first dedicated predictions regulatory framework.

GRAI Names No One, But the Warning Is Unmistakable

Something is stirring in Ireland’s gambling landscape, and the regulator wants it on record. The Gambling Regulatory Authority of Ireland confirmed it is weighing High Court proceedings against a major global prediction market operator that has been serving Irish consumers without a valid licence. Speaking on RTÉ’s This Week on 19 July 2026, GRAI Chief Executive Anne Marie Caulfield stopped short of naming the platform but left no doubt about the scale of the target.

“One of the largest prediction market operators in the world,” she said, had been operating in Ireland without proper authorisation. The GRAI has issued warning letters. One unnamed platform had already moved to geoblock Ireland after what Caulfield described as an intervention that moved at speed, in one instance, as quickly as 35 minutes.

A second platform was confirmed by Gambling Insider on 21 July to have agreed to implement a geoblock by that same date. Both Polymarket and Kalshi now restrict access to Irish users, with the latter having listed Ireland in its Member Agreement as a restricted jurisdiction and Polymarket updating its Geographic Restrictions list on the day the news broke.

What the GRAI Can Actually Do?

The authority’s toolkit, at least for now, is leaner than many would assume. GRAI cannot directly compel internet service providers to block access to sites, a power several European regulators already have. Instead, it relies on legal pressure, warning letters, and the threat of court proceedings to force non-compliant platforms to cut off Irish users themselves.

Caulfield was direct about the consequence of resistance: “In the instance where they don’t do so, we can go to the High Court and get a blocking order for them, a blocking order for access to the site and also in relation to the funding involved.”

That process takes time, and it costs the regulator resources, which softens the immediate danger for any platform that decides to dig in. Still, the GRAI confirmed to Gambling Insider that it has several ongoing investigations into black market gambling activity, with prosecutions described as a distinct possibility. The regulator is also working with Irish media regulator Coimisiún na Meán to acquire “trusted flagger status,” which would eventually allow it to request the removal of non-compliant domains without going through the courts each time.

Under the Gambling Regulation Act 2024, prediction market platforms offering betting services to Irish consumers must hold a GRAI licence. The regulator formally began issuing licences on 1 July 2026, when it took over from Revenue as the licensing authority for remote gambling operators. Fines for non-compliance can reach the greater of €20 million or 10% of annual turnover, and the GRAI has made clear that prediction markets sit squarely within its remit.

Suspicious Bets and Political Scrutiny Came First

The regulator’s move against prediction markets did not come from nowhere. In May 2026, Finance Minister Simon Harris raised what he called “grave concerns” about unregulated betting activity on platforms like Polymarket, pointing to a reported million dollars in trading volume tied to the outcome of the Dublin Central by-election. A significant portion of that activity was wagered against Gerry Hutch securing a seat, which is exactly what occurred.

Harris described the situation as the “Wild West” of online betting and said he would direct gardaí, regulators, and government departments to examine potential money-laundering activity. No wrongdoing was suggested on the part of any candidate. But the scrutiny planted a flag, and the GRAI’s recent intervention appears to be the operational follow-through.

France and Czechia Escalate, Ireland Watches

Ireland’s regulatory posture arrived in the same week France took a harder step. Polymarket was entirely blocked by the Autorité Nationale des Jeux as of 16 July 2026 after being designated an illegal gambling site. France’s internet service providers had done this based on the fact that Polymarket featured addictive features and lacked self-exclusion options, and there were French citizens who managed to bypass the transaction restriction, which had existed since December 2024. Regardless of the existence of the restriction, in June, Polymarket registered 578,751 visits from 205,000 distinct French people.

In Czechia, Polymarket was also blocked on the same date. In Canada, Polymarket left Alberta, British Columbia, and Quebec on 6 July. These joined Ontario, which had been part of the withdrawal process earlier.

The Nine-Country Agreement Europe Built

The pressure on prediction markets in Ireland reflects a wider European pattern that has been building since early 2025. In June 2026, nine countries formally committed to a shared surveillance framework; Spain, France, Germany, Italy, Portugal, Belgium, the Netherlands, Poland, and Switzerland all signed a collective agreement to monitor and counter prediction market platforms targeting their populations. The agreement came with a direct warning to sports federations and clubs across Europe to verify whether commercial partners operate in compliance with local gambling law.

Prediction markets are effectively banned across all nine signatory nations. Belgium moved against them in early 2025. Germany hardened its position later that year. France became openly hostile in the first months of 2026. The coalition urged that cross-border coordination continue beyond the FIFA World Cup, which had served as a focal point for enforcement concerns given the volume of event trading on platforms like Kalshi and Polymarket.

Italy tells a particularly sharp story. Polymarket was once again included in the blacklist by the Customs and Monopolies Agency in July 2026. However, in December 2025, the ADM allowed Polymarket to operate again due to a lawsuit. But this second ban has added another burden; now ADM must provide a report to the Public Prosecutor’s Office of Rome. The Italian betting industry welcomed the move, with Betsson’s Southern Europe Managing Director Stefano Tino writing on LinkedIn that licensed operators deserve to compete on a level playing field — a sentiment that captures the mood of regulated incumbents across much of Europe.

Gibraltar Sits on the Other Side of That Line

Not every European jurisdiction is pushing prediction markets out. Gibraltar moved decisively in the opposite direction, becoming the first territory in the world to announce a dedicated regulatory framework exclusively for prediction markets on 13 July 2026. The British Overseas Territory had already licensed two platforms, ADI Predictstreet under a betting intermediary licence, and Wire Markets, approved in principle. Both now fall under the new standalone Gibraltar predictions regime, which will be overseen by a dedicated supervisory authority covering market integrity, participant protections, digital asset usage, and anti-money laundering obligations.

Gibraltar’s Minister for Justice, Trade and Industry Nigel Feetham KC MP said the framework prioritises “effective supervision and robust standards of market integrity, transparency, participant protection and financial crime prevention” over definitional debates about whether predictions are gambling or financial products.

The divide is getting sharper. On one side sit the nine-country coalition, Ireland, and France, jurisdictions treating predictions as unlicensed gambling until proven otherwise. On the other sits Gibraltar, carving out a licensed path for an industry that the rest of Europe is currently trying to wall out. Kalshi’s valuation sits at $22 billion; Polymarket is chasing a revised $15 billion. Neither figure has buckled under regulatory pressure. But the list of markets where they cannot operate keeps expanding.

Expert Analysis

Ireland’s enforcement move against prediction markets carries a particular weight precisely because the GRAI is new. The authority was established under the Gambling Regulation Act 2024 and only began formal licensing operations in July 2026, which means this intervention is one of its earliest public signals about where it stands on offshore operators. Threatening the High Court against one of the world’s largest prediction platforms, within weeks of taking over from Revenue, is a pointed statement of intent.

The structural weakness, no direct ISP-blocking power, is real, and any platform that chooses to call the GRAI’s bluff knows that legal proceedings take months and cost money on both sides. But the broader European picture makes that gamble riskier than it looks on paper. With nine countries coordinating, France ordering direct ISP blocks, Italy reopening criminal proceedings, and Czechia following suit, the cost of staying in non-compliant European markets is rising on every front. Ireland may lack the technical reach France has, but it is not operating in isolation. The GRAI’s warning letters now sit inside a continent-wide enforcement momentum that prediction platforms cannot simply ignore.
