Greek online gambling market faces shake-up
Greece's online gambling market is entering a new phase of competition as international operators target market entry, regulators tighten oversight of illegal gambling, and a new tax regime for online casino games comes into force.
Greece’s online gambling sector is undergoing significant change as new international operators prepare to enter the market, increasing competition in a sector currently dominated by a handful of major brands.
The developments come as the Greek government advances legislation aimed at curbing illegal gambling and prepares to introduce a new tax regime for online casino games from July.
Despite the presence of around 17 licensed operators, the market remains highly concentrated. Allwyn, through its Stoiximan brand and digital operations, is estimated to control close to 60 per cent of the market, while Novibet holds approximately 17 per cent.
However, the size and profitability of the sector continue to attract new entrants. Industry figures show that online gambling companies generated net revenue before tax of €1.2bn in 2025, while total online wagers reached €7.7bn during the year.
Two additional operators have entered the market in recent months. Romanian betting and gaming group Superbet launched its Greek platform in March, offering both sports betting and online casino products. The company is backed by international investors, including Blackstone. Regency has also begun operations in the market.
At the same time, regulators are seeking to strengthen controls on illegal gambling, which remains a major challenge for the sector. Unlicensed gambling activity is estimated to account for around €2bn in annual turnover, raising concerns over consumer protection and lost tax revenues.
The combination of new market entrants, regulatory reform and tax changes is expected to reshape Greece’s online gambling landscape over the coming months, as operators compete for market share in one of Southern Europe’s fastest-growing regulated gaming markets.
