Largest Online Casinos Worldwide By Market Cap

Online crypto gambling is one of the largest sectors on the web. With more and more people gravitating towards the activity, the industry is set to expand to reach a value of 92.9 billion U.S. dollars by 2023. 

Although gambling has been around since the beginning of time, it only gained its true fame when it transitioned online, bringing the fun just a few clicks away at any given moment. The next big move was the integration of crypto, dominating significant sectors, like the Asian and Norwegian markets.

With the market currently valued at 59 billion U.S. dollars, the online gambling industry holds plenty of potential for players and providers. 

The Player Vs. The Providers

The gambling industry is often looked at from the player’s point of view, boasting the big wins and exciting games titles, but have you ever thought about the industry from the provider’s point of view?

Whether it be the casino itself or the software developer, the gambling industry is highly lucrative. An example of this is that the gambling industry makes more money than the theatrical movie industry ($10.9 billion) and the recorded music industry ($7 billion) combined.

As you can see, casino providers and gambling companies make themselves a pretty penny, but as the industry grows, so does the quality of companies out there.
