Greek Gambling Market Gross Gaming Revenue Rises 6.74% in 2025

The Hellenic Gaming Commission (EEEP) has released its annual report. According to the report, the gross gaming revenue of the Greek Gambling Market has increased 6.74% in 2025.

More than half of Greek adults (54.5%) participated in at least one form of gambling in 2025, while the online market continued to outpace land-based gaming, according to the report.

The regulator said people aged 25-34 and 45-54 accounted for a disproportionately high share of online gamblers relative to their representation in the general population, reflecting, among other factors, greater familiarity with digital technology and online platforms.

Industry revenue

Gross gaming revenue (GGR) from Greece’s regulated gambling market rose 6.74% year-on-year to 3.073 billion euros in 2025, the report said.

Land-based gambling accounted for 61.2% of total GGR, while remote gambling increased its market share to 38.79%. Online gambling revenue grew by 11.75% during the year, compared with a 3.8% increase for land-based gaming, underscoring the continued shift towards digital channels.

Total revenue generated for the Greek state from gambling reached 1.169 billion euros in 2025, up 11.24% from 2024.

Online betting operators accounted for 63.05% of state gambling revenue, followed by OPAP with 27.95%, casino operators with 5.28% and other licensed providers with 3.72%.

The report also said 3.25 million euros was collected from instalment payments made by licensed online gambling operators as part of the fees for their operating licences.

Illegal market

According to the report, 10.6% of the population participated in unlicensed gambling at least once during 2025.

Participation in illegal gambling was significantly higher online, where 70.5% of respondents reported using unlicensed websites, compared with 56.4% who gambled in unlicensed land-based venues.

Among illegal land-based gambling venues, private gambling clubs were the most common locations, accounting for 63% of participation, followed by temporary “pop-up” venues such as bars or clubs operating gambling events (57%). Internet cafés accounted for 31%.

Slot machines ranked as the second most popular form of illegal gambling, overtaking other casino games compared with 2024.

The main reasons cited for using unlicensed online gambling platforms were more attractive odds or bonuses (38.7%) and the absence of, or less stringent, identity verification requirements (27.6%).

Average spending also varied by age group. Players aged 55-64 recorded the highest average expenditure on illegal gambling at 3076 euros, while those aged 18-34 spent the least, averaging 1223 euros.
