The UK’s gambling has changed a lot in the past ten years or so - thanks to tighter regulation, the growing popularity of online gaming, and the change of technology and trends. In 2025, savvy investors are starting to pay close attention to certain casino stocks that are in the best position to benefit from the ever-changing market conditions. Sites like FruitySlots.com are filled with the very best online casinos - but some of these sites are growing a lot quicker than others… and these are the ones potentially worth investing in.
Interested? Here are five UK casino-related stocks that are well worth watching in 2025.
1. Entain plc (LSE: ENT)
Market Cap (approx.): £7.5 billion
Entain is one of the biggest names in the gambling industry - the company behind some of the biggest names out there, including Ladbrokes, Coral, Bwin, and PartyCasino. The company has been right at the forefront of adapting to the online world and has become a major player all over the world, particularly in the U.S., thanks to its BetMGM joint venture with MGM Resorts.
In 2024, they faced a bit of regulatory pressure in the UK and experienced slower-than-expected growth in parts of Europe. However, they’ve made it clear that it’s now all about technology-driven growth, better AI-based player protection, and going into up-and-coming markets.
Why watch it in 2025?
With Entain’s commitment to responsible gaming technology, its potential U.S. partnerships, and new leadership, it really could be a turnaround year for the stock.
2. Flutter Entertainment plc (LSE: FLTR)
Market Cap (approx.): £27 billion
Then we have Flutter, another UK-based gambling giant - and the owner of huge names like Paddy Power, Betfair, Sky Betting & Gaming, as well as global brands like FanDuel and PokerStars.
The company really is riding the wave of global sports betting expansion, especially in North America. In 2025, investors are looking at Flutter's IPO of FanDuel in the U.S., which could well unlock serious shareholder value.
Why watch it in 2025?
Flutter’s impressive portfolio, strong presence in the U.S. and its leadership in sports betting and poker make it very high-potential, especially with sports betting being legalised in more and more U.S. states.
3. Rank Group plc (LSE: RNK)
Market Cap (approx.): £430 million
Rank Group owns and operates a number of big-name UK casino and bingo brands - including Grosvenor Casinos and Mecca Bingo. Although it’s definitely had its challenges, what with the pandemic and spending slowdowns, 2024 saw buds of recovery… and positive signs of a rebound.
Rank does so well because it manages to maintain a very solid land-based footprint, while still managing to actively grow its online offering.
Why watch it in 2025?
Rank could be a decent recovery stock to go for, as people start getting a bit more confident in the industry again… and their online efforts could really help to deliver growth.
4. 888 Holdings plc (LSE: 888)
Market Cap (approx.): £400 million
888 Holdings is probably one of the most well-known names in the online gaming space, with brands like 888casino, 888poker, and 888sport. In 2022, the company bought William Hill’s non-U.S. assets from Caesars Entertainment, which was a massive boost to its portfolio.
That being said, 2023 and 2024 were tricky years, thanks to executive reshuffling, regulatory issues, and challenges with integration. Despite this annoying turbulence, the company started to restructure, streamline their operations, and renew its focus on the main regulated markets.
Why watch it in 2025?
With more of a brand focus, we could see a pretty positive turnaround. Its reputation, recognition and the fact that it operates in the biggest markets could bode well for the upcoming year.
5. Gamesys Group / Bally's Corp. (U.S. listing, UK influence)
Note: Gamesys was bought out by Bally’s Corporation in 2021, but is still a hugely influential UK-based gaming platform provider.
Although it’s not listed in London, it still plays a huge role behind the scenes in online casinos like Jackpotjoy and Vera&John, which are incredibly popular in the UK and Europe.
Bally’s has very ambitious plans to use Gamesys’ technology to build up its name in U.S. online gaming - and it could become impressively profitable if U.S. online casino legislation starts picking up momentum in the upcoming year.
Why watch it in 2025?
It might be U.S.-listed, but its exposure to UK-developed platforms definitely gives it the edge. If the legalisation of online casinos keeps expanding in the U.S., it could well be right at the heart of a digital gold rush.
So, if you are looking to invest in UK casino stocks, these are the ones to watch!
