Greece iGaming Market Research Report

With a population of approximately 10.4 million, Greece has a very active gambling culture centered on lotteries, sports betting, and casino gaming that generates significant tax revenue for the Greek Government. The iGaming market has grown at an exponential rate, particularly during the second half of 2025, when demand increased by over 50% from June to December, outpacing growth in major European markets, which were experiencing economic slowdowns. One of Greece’s leading iGaming operators, OPAP, experienced double-digit growth rates for online gaming revenue, indicating a shift towards digital gaming platforms.

In addition to increased growth rates across all iGaming segments, there is also a recent tightening of regulations concerning illegal gambling, which was introduced by virtue of a presidential decree announced in 2026. This new law imposes penalties of up to ten (10) years in prison and €100,000 fines for unlicensed gambling operators. Online gaming has grown to now represent 70% of total gaming revenues and reached €28.3 billion for the first eight months of 2024, an increase of 14% when compared to the same period last year. The Hellenic Gaming Commission (HGC) will continue to issue licenses for internet gambling operations pursuant to Law 4002/2011; therefore, creating a regulated online gambling market will establish Greece as an attractive destination for stakeholders interested in converging traditional and technology-based growth in the online gaming market in Greece.

Market Overview

The Greek iGaming market has established itself as the leading market in Europe by 2025, thanks to strong growth in regard to technology and stable regulation. The growth of Gross Gaming Revenue (GGR) and Total Gaming Revenue (TGR) metrics reinforces this position, driven by the rapid growth of online channels.

Table 1: Market Overview

Market Size & Growth

Through the first two-thirds of 2020, the gaming industry achieved TGR of €28.3 billion, a 14% increase compared to last year. Projections for the entire year are expected to exceed €40 billion, primarily as a result of continued growth in the online segment. OPAP’s GGR for H1 2025 was €1.15 billion, a 6.5% increase over the same period last year, including €171.3 million in iGaming (22.1% increase). Based on the most recent prediction from Statista, user penetration will grow at a constant rate to approximately €350 – €400 ARPU by 2026.

Retail/physical lotteries (most OPAP’s H1 2025 revenue segment, €386.7 million) will include draws for Joker and Lotto and will use significant revenue from this draw.

Poker remains a revenue-generating gaming segment that has some revenue growth from poker tournaments, and VLTs/slot machines represent additional land-based gaming revenue (€1.3 billion).

• Top Categories:

• • Sports Betting: 70% online share​
  • Casino (Slots/Live): Rapid 20%+ growth​
  • Lotteries: €386.7M H1 OPAP (+stable)​

Regulatory Landscape

Greece has an organized government-regulated gambling system created to protect consumers and generate government revenue; the Hellenic Gaming Commission (HGC) is responsible for regulating the gambling industry in Greece.  Since 2011, there have been extensive reforms that have liberalized online gaming and reduced illegal activity.

Table 4:  Regulatory Landscape

Overview of Existing Gambling Regulations

All gaming is governed by the Law 4002/2011 (as amended), and distinguishes between land-based gaming (casinos, lotteries) and online gaming (betting, casino). Plants for online retailing are prohibited; only licensed platforms may operate, and unlicensed internet protocol addresses are blocked by HGC while responsible gaming tools (self-exclusion, reality checks, and 24-hour support services) are required to be implemented by all licensed operators. 

The following are prohibited: minors (under 21), using credit to place bets, and unregulated advertising; affiliates must register with the appropriate authorities to avoid being fined. The OPAP is in control of lottery tickets, while the government controls all sports and/or casino-type wagering through licensing.

Licensing Requirements and Regulatory Authorities

HGC, independent since 2006, issues licenses: Type A (online betting/casino, €3M fee + €17.5K annual), Type B (lottery/poker/VLTs, €2M). Applicants need €2M capital, clean records, tech audits (RNG certification), Greek-language sites, and business plans.

Process: Portal submission, 3-6 month review, suitability tests for owners. ~20-25 active online licensees as of 2025.

• Key Requirements:

• • Fees: €3M (Type A), €2M (Type B); €17.5K/year​
  • Capital: Min. €2M solvency proof​
  • Tech: RNG, geoblocking, AML/KYC​
  • Authorities: HGC primary; Finance Ministry oversight​

Taxation and Compliance Details

35% GGR tax headline, plus 24% VAT exemptions for licensed; operators remit monthly, with audits mandatory. Compliance includes quarterly reports, €10K app fee, anti-fraud tech, and player funds segregation.

2024 taxes hit €3.8B+ (13.5% up), funding state programs.​

Upcoming Legislative Changes

2026 decree escalates illegal penalties: 10-year prison, €100K fines, venue closures; municipalities revoke business permits. No liberalization; focus enforcement, potential affiliate tightenings, digital monitoring enhancements.

Table 5: Upcoming Changes

This regime balances growth with integrity.

Competitive Landscape

Greece’s iGaming arena blends OPAP’s monopoly dominance with competitive online licensees, fostering innovation amid 2025 growth. Traffic and revenue metrics highlight a dynamic, digitally skewed field.

Table 6: Competitive Landscape

Key Market Players

OPAP leads as the exclusive operator for lotteries, retail betting, VLTs (25,000 cap), and horseracing, with online via Stoiximan (full ownership post-2025 acquisition) and Pamestoixima.gr. H1 2025 GGR: €1.15B (+6.5%).

International/local licensees include Stoiximan.gr (17.54M monthly visits Dec 2025), Novibet.gr (11.11M), Bet365.gr (7.57M), Kwiff.com, and others like Kaizen Gaming. Suppliers: Pragmatic Play, CT Interactive, AbZorba Games.

• Top Operators:

• • OPAP/Stoiximan: Lotteries/iGaming leader
  • Novibet.gr: Strong casino/sports
  • Bet365.gr: Betting heavyweight
  • Others: Kwiff, Pamestoixima

Market Share Distribution

Around 50-70% of OPAP’s revenues come from lotteries and the retail market (being a monopoly), with only approximately 30-40% of revenue generated through online gaming (via Stoiximan or Pamestoixima). Stoiximan receives the highest volume of traffic (17.54M visits); Novibet and Bet365 follow closely behind in terms of volume of traffic. Online sports betting and casinos are very fragmented, with 20+ licensees, while VLTs are only operated by OPAP.

The digital shift has allowed international companies to strengthen their market presence in Greece; however, OPAP’s profitability of €233 million (H1) serves to maintain its dominant position in this space.

Partnerships and Strategic Alliances

OPAP (the Greek state lottery) increased its ownership of Stoiximan (191.6 million euros; full control) and launched a new version of Pamestoiximi to drive increases in Arcade Gaming revenues. Pragmatic Play has also expanded its operations by adding Bet365 (slots/live gaming; Drops & Wins). CT Interactive has partnered with Novibet to provide slots (e.g., Lucky Clover) to its customers.

The alliances being formed in Greece are focused on providing new types of content (also known as content/technology integrations) and can be characterized by all of the following: (1) Analytic capabilities (e.g., Blask); (2) Integrated Patents (for OPAP); and (3) OPAP’s acquisition of 100% of Brightstar (via OPAP Investments Ltd.) will lead to the government being able to conduct business with both parties after receiving the appropriate approvals from the Lottery Board.

These business arrangements indicate continued consolidation of companies and ongoing competition among digital companies.

Social and Cultural Influences on iGaming

These trends favor agile, localized operators.​

Opportunities & Challenges

The Greek market’s rapid growth in the iGaming and digital betting sectors (50%+) by 2025 is attracting new market entrants, especially with available licenses from the Hellenic Gaming Commission (HGC) at €2 to 3 million each. Investors can pursue hybrid opportunities similar to OPAP, as well as mobile/crypto integration, and increased female and Gen Z clientele.

There are several challenges facing prospective online betting operators in Greece, including a 35% GGR tax rate, strict and extensive compliance/audit requirements, and the risk of being unable to operate after illegal crackdowns in 2026 (impacting the ability to operate offshore).

In addition to regulatory challenges, operators must overcome operational challenges related to demographic profile (specifically male demographic), strong competition from OPAP, and using innovative technologies like blockchain payments, AI personalisation, and responsible gaming technology as potential investment opportunities, and collaborating with local operators to facilitate entry into the Greek market.

Table 10: Opportunities & Challenges

Conclusion & Recommendations

OPAP is leading the way in growing the iGaming market in Greece; its online presence accounts for 70% of the total gross revenue generated from this industry. And while regulations are tightening, there are still bright spots in Greece’s market—i.e., the growing number of under-30 individuals in Greece and the digital revolution—that point to continued growth further down the road.

There are some things operators can do to ensure a valid and reliable place within Greece’s iGaming market moving forward include acquiring Type B licenses, developing an infrastructure that allows for the use of crypto or electronic wallets, and promoting responsible gambling practices to remain compliant with HGC regulations.

To investors looking to enter Greece’s iGaming market: Partner with a local company, and focus on developing niche products within the iGaming space.

Long-term outlook through 2026 remains positive; once enforcement of HGC regulations begins, annual gross revenue generated from the iGaming industry in Greece could exceed €30 billion if digital continues to grow.
