Bulgaria’s regulated online gambling market generated approximately €562m in gross gaming revenue in 2023, supported by a licensing framework administered by the National Revenue Agency (NRA) and a domestic B2B ecosystem that distinguishes the market from most of its Eastern European peers. The market enters 2026 under the first significant tax rate change in several years and a near-total advertising ban that has already reshaped the competitive field.
Regulatory Framework
Online gambling in Bulgaria is governed by the Gambling Act of 2012, substantially revised in May 2024. The NRA replaced the former State Commission on Gambling in 2020 and now administers all licensing, compliance monitoring, and tax collection.
The licensing framework is open to companies registered in EU and EEA member states, as well as Switzerland, without requiring a local partner. Applicants must demonstrate minimum paid-in share capital of BGN 1.5m (approximately €767,000), pass fit-and-proper checks for directors and beneficial owners, and submit all gaming software to NRA technical inspection before launch. Online operators pay a one-time issuance fee of BGN 400,000 (approximately €200,000), a recurring annual maintenance fee of the same amount, and an annual BGN 50,000 contribution toward responsible gambling causes. Post-approval, a minimum investment of BGN 1m (approximately €511,000) is required within six months. Licences run for five years and are renewable.
Technical requirements are demanding relative to comparable EU frameworks. Operators must transmit real-time data to NRA servers covering player registration, bets placed, and winnings paid. Gaming software and any subsequent updates require separate NRA approval before deployment. Central computer systems must be hosted within the EU, EEA, or Switzerland.
The May 2024 amendments introduced a near-total advertising ban across television, radio, print, and online media websites. The restrictions accelerated operator exits: LiveScore Bet confirmed its Bulgarian withdrawal before the end of 2025, citing the advertising environment alongside rising UK tax obligations. The NRA also raised the minimum self-exclusion period from 30 days to one year in March 2025, with approximately 54,000 players registered on the national exclusion database.
Bulgaria formally joined the eurozone on 1 January 2026, becoming the 21st member state. The transition fixes the Bulgarian Lev at 1.95583 to the euro, formalising a peg in place de facto for over two decades and removing currency conversion friction for EU-based operators reporting consolidated financials.
Market Size
The regulated online gambling sector generated approximately €562m in GGR in 2023, according to analyst firm Yield Sec. Total gambling market revenue, incorporating land-based and online, was estimated at approximately €1.1bn for the same year. Statista market forecasts put online GGR at €561m (BGN 1.1bn) for 2025, supported by continued growth in online casino, which is projected to outpace sports betting at approximately 30% versus 12% year-on-year for the 2025 to 2029 period.
Player ARPU is estimated at approximately €450 for 2025, a high figure for an Eastern European market with a national population of approximately 7 million. Active online players are estimated at around 1 million, implying penetration of roughly 14% of the adult population.
The market currently has approximately 22 licensed operators, a substantial expansion from the six active before 2020, when the operator group linked to Vasil Bozhkov had its licences suspended following criminal proceedings. That reset opened the market to an influx of EU-licensed international brands. Bulgaria is positioned within the broader Eastern European iGaming cluster, which continues to outperform Western European markets on growth rate if not on absolute GGR volume.

Top Operators
Winbet holds a commanding position at 10.59m monthly visits, nearly 10 times the traffic of its nearest domestic competitor and still growing at 16.86% year-on-year. The brand is linked to Walter Papazki and operates one of the largest combined land-based and online networks in the country.
Palmsbet, traded publicly via Telematic Interactive Bulgaria, ranks second at 4.85m visits with a 96.89% mobile share, the highest in the tracked set. A marginal traffic decline of 4.35% year-on-year is a modest negative for a brand maintaining scale under heavy advertising restrictions.
Efbet, owned by the Naydenov brothers and the previous market leader before Winbet’s ascent, holds 2.46m monthly visits with 12.97% year-on-year growth. The brand spans sports betting and casino under a single NRA licence.
Bet365 draws 1.85m monthly visits but is down 29.08% year-on-year, the sharpest decline among licensed operators in the tracked set. The May 2024 advertising restrictions reduce the acquisition toolkit available to international brands that depend on media spend. Bet365 entered Bulgaria via a content arrangement with Amusnet Interactive, giving it access to locally certified game catalogues.
Toto.bg, operated by the state lottery, generates 1.02m visits but is in structural decline at -27.24% year-on-year. The pattern is consistent with data from comparable regulated markets: Latvia reported similarly mixed sector performance in 2025, with lottery products losing share to online casino and sports betting.
Betano’s 40,580 monthly visits with a 209.74% year-on-year growth rate is the most significant forward indicator in the dataset. Kaizen Gaming’s brand has executed a rapid build-out in several Eastern European regulated markets including Romania, and the Bulgarian traffic trajectory suggests the same playbook is in motion.
Affiliate Sites and Player Communities
Three affiliate and community domains in the tracked dataset merit attention beyond their visitor numbers: BigWinBoard.com (+290.67% year-on-year), Betbrain.com (+160.37%), and AskGamblers.com (+22.27%). All three sit below 100,000 monthly Bulgarian visits individually, but their combined growth direction tells a consistent story — Bulgarian players are increasingly relying on third-party, community-backed platforms to evaluate operators before depositing.
This dynamic is partly structural. The May 2024 advertising ban removed the primary direct-to-player communication channels that operators had used to acquire and retain customers. In the absence of above-the-line marketing, players have more reason to consult independent comparison and review sites, and affiliates with established organic search positions gain relative influence. The growth of all three platforms in the Bulgarian market since the restrictions took effect is consistent with that shift.
Betbrain is the most historically significant of the three. Founded in 2000 and acquired from EveryMatrix in 2019 by GSH Online Media, the platform is owned and operated by Viorel Stan, the Bucharest-based entrepreneur and CEO who co-founded GSH Online Media after leading EveryMatrix’s B2C division. Betbrain is the oldest odds comparison site on the market and has since evolved to incorporate betting tips, community features, and a social betting layer. Its 98.29% mobile share in Bulgaria, the highest in the entire tracked dataset, reflects how thoroughly its Bulgarian audience has migrated to app-based consumption. The 160.37% year-on-year growth suggests either a deliberate push into the Bulgarian market or organic momentum driven by the post-advertising-ban search for trusted operator information.
BigWinBoard, a casino review and bonus comparison site, leads the three on growth rate at 290.67% year-on-year off a lower base. AskGamblers, the most internationally recognised of the group and a long-established destination for player complaints and operator reviews, grows at a steadier 22.27%, its scale reflecting an established audience rather than a new market push.
For operators active in Bulgaria, the implication is straightforward: affiliate relationships and organic search presence have replaced paid media as the primary acquisition infrastructure. Operators without strong affiliate partnerships or favourable community-site ratings enter 2026 at a structural disadvantage that no direct advertising budget can currently offset.
Tax Regime and the 2026 Rate Change
From 1 January 2026, Bulgaria raised the variable component of its gambling tax from 20% to 25% of GGR, covering online casino, sports betting, lotteries, and bingo. The government projected the change would generate approximately €56m in additional annual revenues, roughly 1.4% of the national fiscal deficit of €3.86bn. The structural impact on operators is higher than the headline figure implies: the tax applies to gross revenue with no deductions permitted for marketing, staffing, or platform costs.
The Government cited European precedent. The Netherlands moved to 34.2% of GGR in 2025. The UK confirmed a 40% rate on online casino GGR from April 2026. At 25%, Bulgaria remains well below those benchmarks. A Betting and Gaming Council study published ahead of the rate change identified 25% as the point at which historical growth in state gambling tax revenues begins to decelerate. The Government’s decision to land at precisely that threshold suggests awareness of the trade-off between yield and market health.
Online operators additionally pay 10% corporate income tax on profits where incorporated in Bulgaria. Combined with fixed annual licence fees and responsible gambling levies, the total cost base for regulated operation has increased materially since the second half of 2024.
The 2026 operating environment is defined by that cost increase, the advertising restrictions that limit growth levers, and Winbet’s entrenched traffic dominance. The structural decline of the state lottery, the early-stage growth signals from Betano, and the rising influence of affiliate and community platforms over player acquisition are the clearest directional indicators in the current data.
