The biggest gambling companies in Europe and their regulatory challenges

The European gambling industry is rapidly growing. The online segment expands 11% every year and is expected to grow from nearly $30 billion in 2022 to more than $84.5 billion by the year 2032.

In 2024, the gambling industry in Europe reached about €123.4 billion GGR, which marks a rise of roughly 5%. The motors that drive this growth include the high mobile use, 5G networks, and the shift from land-based venues to online platforms.

This growth is especially present in liberalized gambling industry markets such as Germany, the Netherlands, Sweden, and Spain. However, regulation still is a major issue for this industry, and sites like casinobonuszok.com show us how rules vary across Europe and how operators adjust to different requirements.

Flutter Entertainment

Flutter Entertainment is one of the top casinos and sits basically in the center of the gambling industry in Europe. This casino operates from Dublin, Ireland, and trades on both the NYSE and the LSE.

Flutter Entertainment is a massive group that controls leading brands like Paddy Power, Betfair, Sky Bet, Sky Vegas, Tombola, PokerStars, Adjarabet, and FanDuel.

PokerStars is a leading platform when it comes to global poker tournaments. This allows Flutter online casino Europe to shape the online gambling market. The company runs charity programs across sports, including mental health initiatives and community projects.

As the largest betting group in the gambling industry, Flutter sets the pace for European bookmakers. However, its immense growth leads to many new challenges. These include tighter gambling regulations, higher compliance costs, and the need to create a gambling license in each market.

All these factors create pressure for Flutter Entertainment and other companies in the gambling industry that push for new markets.

Notable cases of Flutter Entertainment

Since it's one of the largest in the gambling industry, Flutter Entertainment is one of the busiest companies in the industry when it comes to regulatory cases.

• £184,500 penalty (2025): In 2025, its brand Tombola received a £184,500 penalty from the UK Gambling Commission for breaches of social-responsibility rules tied to marketing and self-exclusion. Flutter said that Tombola acted immediately to correct the issue.
• A Reprimand (2023–24): In 2023–24, the UK Information Commissioner’s Office issued a reprimand to Sky Betting & Gaming for sharing customer data with ad partners through cookies without clear consent.

Both of these cases highlight how major gambling companies in the gambling industry face growing pressure in these fast-developing markets like the online casino Europe niche.

Entain PLC (previously GVC Holdings)

Entertain PLC, based on the Isle of Man, is a leading force in the online casino Europe and the gambling industry in Europe as a whole. This giant, listed on the London Stock Exchange, possesses a lot of brands that include LadBrokes, Coral, bwin, PartyPoker, Sportingbet, BetCity, Neds, and Ladbrokes Australia.

PartyPoker specifically hosts many high-stakes poker tournaments, boosting Entain’s presence in online casinos in Europe. The company is growing steadily through the many acquisitions it makes. Entertain expands in many different markets and ensures full compliance with local gambling regulations.

Entain also frequently engages in charitable activities. The company supports many community initiatives and sports programs.

Overall, Entertain has a strong casino and betting offering. It is a major player across Germany, Italy, Spain, and other European markets, thus influencing the broader online gambling market and the strategies of other companies in the gambling industry.

Notable cases of Entain PLC

However, there are still some regulatory and legal challenges Entain faced in recent years.

•  £17m Settlement (2022): In 2022, the company agreed to make a settlement of £17m with the UK Gambling Commission for serious social-responsibility and AML failings, including weak checks on high-risk customers and ineffective safer-gambling measures.
• Bribery and Corruption Case (2011-2017): Between 2011-2017, they also had issues with their Turkish-facing online casino Europe business, where bribery and corruption occurred. Entain reached a DPA with the CPS, paying £585m in penalties, £20m in donations, and £10m costs for CPS/HMRC, while avoiding a criminal conviction.
• £100m Claims (2025): In 2025, a few former Entain/GVC executives were charged over the same operations. Investors have since launched claims exceeding £100m, and the UK Financial Reporting Council is investigating audits of Entain’s 2022 accounts.

Overall, it has been a rough few years for Entain in the gambling industry.

Kindred Group (formerly Unibet Group Plc)

Kindred Group, previously known as Unibet Group PLC, is a leading “pure play” online casino Europe operator with a digital-first strategy. This operator is registered in Malta and has major hubs in Gibraltar, London, and Stockholm.

Kindred Group has a very strong portfolio, one of the best in the gaming industry. This includes Unibet, 32Red, Maria Casino, Bingo.com, iGame, and Relax Gaming, covering both sports betting in Europe and online casino offerings.

From its portfolio, Unibet is the strongest name. This casino hosts well-known poker tournaments, enhancing its reach in the online gambling market.

Kindred Group is focused on expanding into regulated markets while still maintaining compliance with gambling regulations.

Despite being smaller than Flutter or Entain, Kindred remains influential in shaping the online casino Europe, by supporting responsible gaming initiatives in the gaming industry, and engaging in community and charitable programs.

Notable cases of Kindred Group

But still, there are some regulatory cases involving Kindred Group that you need to know about:

• £7.1m UKGC penalty (2023) – In 2023, the UK Gambling Commission fined Kindred subsidiaries 32Red Limited and Platinum Gaming Limited (Unibet UK) for failing to meet the social-responsibility and AML criteria. Some of these issues included a customer depositing £43,000 and losing £36,000 in seven days without proper checks, weak monitoring of long sessions, and allowing self-excluded 32Red players to open Unibet accounts.
• £10m UKGC fine (2025) – Also, a Kindred-owned bingo brand faced a £10m penalty for AML and social-responsibility failings. Customers lost large sums without interventions, including over £5,000 within 24 hours of registration and more than £31,000 over nine months despite repeated harm markers.

Overall, Kindred Group primarily focused on regulatory challenges concerning social responsibility. These fines helped Kindred become more socially responsible and implement fairer play in the gambling industry.

Betsson AB

Betsson AB is a long-standing player in the online casino Europe. This company is listed in Sweden and has been active since 1963. One of the oldest in the industry. This group runs several well-known brands in the gambling industry, including NordicBet and Betsafe, which hold strong positions in the Nordics and continue to grow across other European markets.

Betsson is very well-known for its strong blend of casino with sports betting, giving it a broader reach in both verticals and helping it compete with larger operators in the online gambling market.

This operator hosts poker events through its brands and supports many sports and community projects as a part of its charitable events.

In recent times, Betsson AB has started to focus on expansion into regulated regions outside the Nordics, along with selective acquisitions that strengthen compliance with gambling regulations.

Although Betsson is smaller than Flutter or Entain, it remains a key regional force and influences how online casinos in Europe evolve.

Notable cases of Betsson AB

Betsson, like many other companies in the gambling industry, has some notable cases. Here are some of them:

• Swedish Supreme Court refund ruling (2025) – The court in Sweden ordered Betsson’s Malta-based BML Group to repay about €500,000 to a player who gambled between 2009–2014. The ruling of the court stated that Betsson should not have accepted wagers from a player who was showing clear addiction markers under Swedish consumer-protection standards.
• Dutch customer refund case (2025) – The court in Rotterdam ordered Betsson to repay roughly €385,000 to a Dutch player. The court decided that Betsson held no licence in the Netherlands during the period when the Dutch customer gambled, making those gambling contracts unenforceable.

888 Holdings PLC

888 Holdings PLC is a major player in the European gambling industry. This casino operates from Gibraltar and runs several very well-known brands such as 888casino, 888sport, and 888poker.

This company has a strong reputation in the online casino Europe. Especially when it comes to poker. With 888poker hosting regular tournaments, they attract players from various markets.

The strategy of 888 Holdings PLC focuses on digital growth and expansion into regulated markets, supported by acquisitions like the purchase of William Hill’s non-US assets. This move boosted its reach in retail and online sports betting while still keeping casino and poker at the core of its offer.

888 also has a strong community and responsible-gaming programs through its various charitable efforts. Although it is smaller than Flutter and Entain, it is still influential in the gambling industry and continues to shape how online casino Europe evolves.

Notable cases of 888 Holdings PLC

Similar to other companies, 888 Holdings also has its own fair share of cases with regulators:

• £19.2m UKGC penalty (2023) – Three of the William Hill entities owned by 888 (williamhill.com, mrgreen.com, and retail shops) were fined a combined £19.2m for major social-responsibility and AML failings. The UKGC called these breaches “widespread and alarming,” marking the largest fine issued at that time.
• £9.4m UKGC fine (2022/23) – The UKGC fined 888 UK Limited £9.4m for weak AML and safer-gambling controls. Some of the failings included allowing deposits in the casino up to £40,000 before checking source of the funds, accepting verbal income claims, and letting one customer spend more than £65,000 in five months without proper oversight.
• £7.8m UKGC fine (2017) – 888 previously faced a £7.8m penalty for failing to implement self-exclusion after customers blocked from casino products were still able to gamble on other 888 platforms.

Overall, although smaller in size in the gambling industry, 888 Holdings PLC had its fair share of issues with the UKGC.

The future of the European market

So, what does the future hold for online casinos in Europe? Well, this market rests on two strong forces. Number one is the rapid technological progress, and the second is the strict oversight.

Large operators drive change as they expand into regulated markets, buy local brands, and invest in safer-gaming tools, AML systems, and AI risk models.

These large casinos in the gambling industry also push for new formats such as live casino, instant games, and cross-platform betting. These features shape how players interact with online platforms.

These gains come with heavy pressure from tough licensing rules, high fines, and tighter affordability checks that make risk control central to long-term success. Still, the overall outlook is positive. Having clear regulations, active supervision, and strong compliance standards creates a stable environment for growth in the gambling industry in Europe.
