The business of Esports is flourishing. Nine of the top 12 Esports companies listed by Forbes are valued above $100 million each.

The esports industry world over is expanding at a galactic pace and is poised to cross $1.5 billion mark in global revenues with a fanbase of 600 million gaming enthusiasts by 2020, according to an estimate by Deloitte.

The growth drivers of the industry, without a speck of doubt, are esports companies that are constantly buying and selling teams and players to compete in the best leagues around and build audiences on various social media and streaming platforms, including Youtube and Amazon’s Twitch.

Cloud9, with estimated net worth at $310 million, is the most valuable professional esports company around the world, boasting of 92 players across 12 owned teams and annual revenues crossing $22 million per annum.

The five-year-old company, owned by Jack and Paullie Etienne, has raised $50 million in Series B funding this month. A chunk of that will go toward building a 20,000-to-30,000-square-foot training facility and home base for its operations in Los Angeles, scheduled to open in 2019.

The US-based company is also leading other counterparts from a competitive standpoint as well. Its North American LOL team made its sixth-consecutive appearance this year at the World Championships, the longest streak of any team in the esports. In July, its London Spitfire became the first-ever champion of the Overwatch league. In January its Counter-Strike: Global Offensive team became the first North American squad to take top honours at a major tournament.

Team SoloMid, at $225 million, is the second-most-valuable company and the only one known to be with positive cash-flow. In terms of revenue, the company tops the chart with $25 million raked in annually. It also has the most successful North American team in League of Legends with six titles. Founder and former player Andy Dinh has plans for TSM to be the Dallas Cowboys of esports.

Team Liquid is close behind SoloMid at the third spot with net worth estimated at $200 million. The other companies estimated to be worth over $100 million in the top 12 roster are Echo Fox, OpTic Gaming, Fnatic, Gen.G Esports, G2 Esports and Immortals.

Forbes’s report suggests that player costs tend to exhaust half of an esports company’s operating budget, with the vast majority of gaming organisations still making losses as they continue to spend money to build their rosters and brands.
