Gambling has always fascinated people in every corner of the world, from the US to the most distant parts of Australia. It generates excitement and gives players a chance to win money, a combination that can be difficult to resist. As iGaming has enabled everyone to place bets and try their luck, people have grown to be picky, so now they have many expectations from the platforms they frequent. 

The ability to access money quickly is one of the key requirements of gamblers, especially Australians.

That’s why in 2025, organizations capable of meeting the demand for friendlier gambling opportunities enjoy absolute leadership in the market. 

It’s time to discover the biggest online gambling companies in the world and learn what they offer. 

Flutter Entertainment

Flutter Entertainment appeared in 2016 as a result of the merger of two iGaming giants, Paddy Power and Betfair. By 2025, it stands as one of the biggest gambling companies in the world, and it owns multiple popular brands. Let’s take a quick look.

• Betfair. This brand is known for its innovative approach to betting: its users can bet against each other, which raises the stakes and makes the whole process socially oriented.

Flutter Entertainment consistently enhances its market leadership by acquiring well-known brands with an excellent reputation. Its revenue reached 14.05 billion dollars by the end of 2024. This is an increase by two billion from 2023, which underlies the popularity of this company. 

Entain

Extensive game selections are a strong point of attraction for gamblers, as people are interested in trying different games before choosing their favorite. This is something Entain ensures. It’s one of the world’s biggest gambling companies with an excellent portfolio and licenses in 18 countries. 

Founded in 2004, it has never stopped evolving, earning a place on the London Stock Exchange and acquiring multiple respectable brands. The most noteworthy examples include:

Bet365

Bet365 is one of the oldest and biggest online gambling companies in Britain and beyond. It is privately owned, a fact that hasn’t changed since its emergence back in 1974. While the company shifted to the online industry in 2000, it stayed just as independent.

In March 2025, Bet365 stopped operating in China, but despite the loss of such a profitable slice of the market, it maintains its popularity as a gambling leader with a significant global reach. 

MGM Resorts and BetMGM

Many people, especially those located in North America, know the name MGM Resorts. This company operates in the hospitality and entertainment sectors, and it has almost 40 years of stellar experience. 

BetMGM is a child of MGM Resorts and the aforementioned Entain. While it appeared only in 2018, it has already become a leader in the gambling industry, relying on MGM Resorts’ luxury name and Entain’s technologies. Right now, it offers:

• A developed sportsbook. BetMGM has partnerships with several major sports leagues, and it supports multiple events that every sports betting fan is interested in. 

• Online casino games. There is an impressive selection of casino games on this platform, from common titles to lesser known but equally entertaining options. 

• Constant portfolio expansion. BetMGM keeps expanding its live dealer options to appeal to an even wider audience.      

There are many rising Australian athletes in 2025, and with BetMGM, it’s possible to place bets on any of them. Also, BetMGM has just entered a partnership with Push Gaming, intending to redefine the gambling markets in Canada and the US. Such a bold step underlines its reputation as a developing global leader.

Focused game development helps Evolution stay relevant and keep many iGaming operators well-stocked with its exclusive titles.
