Greece online gambling drove 88% of market growth in H1 2026, HGC briefing

Online gambling accounted for 88% of the growth in Greece's regulated gambling market during the first half of 2026, the Hellenic Gaming Commission reported at a 6 October briefing. Total gross gaming revenue for H1 2026 reached €1.558 billion, an 8% increase on the prior period, with online gross gaming revenue up 18.7% to €647.2 million and land-based GGR at €910.6 million.

Greece online gambling: the headline numbers

Online operators contributed €102.1 million of the market's growth in H1 2026, leaving land-based channels responsible for only €13.9 million of the advance despite still holding the larger share of total GGR. The online segment increased its market share to 41.5%, up from 37.8% in the comparable period. GGR is calculated after player winnings and before operator costs and taxes, so it should not be conflated with total stakes or corporate profit.

State revenue and the regulatory context

Revenue flowing to the Greek state rose 14.4% to €627.3 million in the first half of 2026, up from €548.3 million in the prior period. The Hellenic Gaming Commission (HGC) presented these figures at a briefing held on 6 October that followed new legislation designed to strengthen the commission and tighten sector regulation. Minister of National Economy and Finance Kyriakos Pierrakakis spoke at the briefing and underlined enforcement activity.

“Popularity offers no immunity, and influence carries responsibility,” Pierrakakis said, in a translation from Greek, when announcing the filing of criminal complaints against 18 influencers for gambling promotion.

The HGC president, Antonis Vartholomaios, reiterated the regulator's position on market structure: a regulated market with clear rules for all providers is the foremost precondition for protecting the player, he said in a translated remark.

Enforcement tools: AI and influencer investigations

The Hellenic Gaming Commission now employs an AI platform to identify websites that may offer or promote unlicensed gambling. The system collects and analyses evidence intended to support regulatory action, according to the commission's briefing. The AI capability forms part of a broader compliance and enforcement push tied to the recent legislative changes.

The minister's announcement that authorities had filed criminal complaints against 18 influencers followed the deployment of these tools. The complaints relate to promotion of gambling outside the regulated framework; Pierrakakis' statement frames the action around accountability for influential online figures.

Market forecasts and longer-term outlook

Deloitte Business Solutions produced the HGC's market forecast, projecting that online gambling could represent roughly half of a €5.25 billion Greek gambling market by 2040. Its study, prepared for the HGC, forecasts average annual growth of 4.6% between 2026 and 2030.

Those projections place the current acceleration of online activity — an 18.7% rise in GGR in H1 2026 — into a multi-decade context where digital channels gain share but land-based venues remain significant. The HGC presentation contrasted the short-term surge in online revenue with the slower expansion of brick-and-mortar receipts.

What operators and suppliers should note

Operators and platform vendors should expect continued regulatory scrutiny tied to both the AI-driven monitoring the HGC now uses and the tougher legal framework enacted earlier in 2026. The briefing made clear that enforcement will include action against promotional channels outside the licensed ecosystem, including influencer activity. Commercial strategies that rely on heavy third-party promotion may face compliance risk if those channels fall outside regulated advertising rules.

Operators already active in Greece will monitor whether the HGC's enforcement activity affects traffic sources and acquisition costs. Suppliers of compliance tooling and content-monitoring services may see demand as regulators apply automated surveillance to the local digital ecosystem.

How the numbers break down

• Total regulated GGR, H1 2026: €1.558 billion (up 8%).

• Online GGR, H1 2026: €647.2 million (up 18.7%).

• Land-based GGR, H1 2026: €910.6 million (up 1.6%, adding €13.9 million).

• Contribution to growth: online €102.1 million, land-based €13.9 million (online = 88% of growth).

• State receipts, H1 2026: €627.3 million (up 14.4% from €548.3 million).

Where this sits in the regulatory calendar

The HGC briefing on 6 October followed legislation to strengthen the commission's powers and to regulate the sector more tightly. The combination of statutory change and new technical tools suggests Greek authorities plan to pair tougher rules with automated detection and more assertive enforcement.
