Greek Gambling GGR Hits €3.07bn as Online Growth Accelerates
The Greek regulated gambling market generated €3.073bn in gross gaming revenue during 2025, up 6.74% year-on-year, according to the Hellenic Gaming Commission’s annual report. Online revenue rose 11.75%, as player spending continued to shift toward remote operators. More than half of Greek adults participated in gambling during the year. The regulator reported that 54.5% of the adult population used at least one gambling product in 2025.
Online Gambling Gains Market Share
Land-based gambling remained the largest segment and accounted for 61.2% of total GGR. Remote gambling increased its share to 38.79%. By comparison, land-based revenue increased just 3.8%, versus 11.75% for online operators, a gap that continued to widen between the two segments.
People aged 25–34 and 45–54 represented a higher proportion of online gamblers than their share of the general population, the Hellenic Gaming Commission said. This was linked partly to greater familiarity with digital technology and online gambling services.
Gambling also generated €1.169bn for the Greek state in 2025, an increase of 11.24% from the previous year. Online betting operators contributed 63.05% of state gambling revenue. OPAP accounted for 27.95%, casino operators contributed 5.28%, and other licensed providers generated the remaining 3.72%. The state also collected €3.25m through instalment payments from licensed online operators, linked to operating licence fees.
Unlicensed Gambling Reaches 10.6% of the Population
According to the report, 10.6% of the population took part in unlicensed gambling at least once during 2025. Among respondents who used illegal gambling services, 70.5% said they used unlicensed websites, while 56.4% took part through illegal land-based locations.
Private gambling clubs were the most commonly reported land-based option, cited by 63% of participants. Temporary gambling events in bars or clubs followed at 57%, while internet cafés accounted for 31%. Slot machines became the second most popular illegal gambling product in 2025 and overtook other casino games compared with 2024.
Better odds or bonuses were the main reason cited for choosing unlicensed websites, reported by 38.7% of users. Another 27.6% cited weaker identity verification requirements or the absence of such checks. Players aged 55–64 recorded the highest average expenditure on illegal gambling at €3,076. Those aged 18–34 reported the lowest average spend at €1,223.
💡TGJ Take
Greece’s 2025 figures show that online operators now capture a larger share of growth, even though land-based gambling still retains most market revenue. The bigger concern for licensed operators is the 10.6% participation rate in illegal gambling, particularly since better bonuses and weaker identity checks remain the main reasons players choose unlicensed sites. Compliance costs alone will not protect the regulated market. Operators need competitive offers and faster verification processes that do not push players toward illegal alternatives.
