ESRI Study: 54% of Irish Online Gamblers Hold a Second Account, 4 in 10 Drift to Casino

New ESRI research commissioned by the GRAI finds that 77% of Irish gamblers bet online, 54% of online account holders have opened a second account, and almost four in ten people who signed up to bet on horses or sport went on to casino games, slots or scratch cards. The study, published on 4 November 2026, is the most detailed picture of day-to-day gambling behaviour in Ireland since the regulator was established.

The Numbers

Patterns of online and in-person gambling in Ireland (Robertson, Ó Ceallaigh, Timmons and Lunn, ESRI Behavioural Research Unit) is based on an anonymous online survey of 1,000 adults who had gambled in the previous twelve months. The headline findings:

FindingShare of respondents
Gambled online in the past year77%
Gambled in person in the past year59%
Gambled both online and in person44%
Hold at least one online gambling accountabout 80%
Online account holders who opened a second account54%
Online gamblers with four or more accountsabout 10%
Opened an account for horse/sports betting, later tried casino games, slots or scratch cardsalmost 4 in 10
Trying, or intending, to reduce their gambling25%

The reasons given for opening a second account were practical rather than dramatic: better odds on a particular event, easy registration, and sign-up or reload offers. Around one in five online sessions interrupted another activity such as work or family time, and roughly one in ten online gamblers said they had bet during working hours.

Why the "Second Account" Figure Matters

For the regulator, multiple accounts are a consumer-protection problem: deposit limits, time-outs and self-exclusion set with one operator do nothing at the next one. GRAI chief executive Anne Marie Caulfield said the research confirms the need for the new obligations on licensed operators, particularly around account opening and closing, the ability to set spending limits, and advertising restrictions. The National Gambling Exclusion Register, due in 2027, is designed to close exactly this gap by applying one exclusion across every licensed operator.

For punters there is a second, less obvious point. The study found that many accounts opened for sports betting end up being used for casino-style products through cross-selling — free spins offered alongside a football bet, for example. That is where the current licensing regime stops. As of 7 November 2026 the GRAI register lists 41 online betting licences (37 remote betting and 4 betting intermediary) held by 39 companies, and no casino or gaming licence of any kind. Gaming licences are not expected before 2027–2028. A second account opened for slots or roulette is therefore, by definition, with an operator licensed somewhere other than Ireland, and the GRAI's new account and advertising rules do not reach it.

What the Regulator Said

Launching the report, Minister for Justice Jim O'Callaghan called it the latest instalment in the ESRI's research series on the Irish gambling landscape. Pete Lunn, head of the ESRI's Behavioural Research Unit, noted that most people gamble for entertainment without harm, but pointed back to the institute's earlier estimate that one in 30 adults in Ireland experiences problem gambling. The ESRI added that further work is needed to establish whether expanding from betting into other products is itself linked to harm.
