Fortnite and Unreal Engine maker Epic Games has almost doubled in value in the last year
That's according to figures from Bloomberg, which say the North Carolina based games giant is now worth $8.5bn - up from 2017's $5bn.
To the surprise of no-one, Fortnite is behind this massive growth. The game's free-to-play model is also credited with helping Epic out, with analysts telling Bloomberg that this is responsible for some of the highest revenue-per-user figures in the market. Additionally, this has meant operating margins are more than 50 per cent.
The growth will be particularly good news for both CEO and controlling shareholder Tim Sweeney - who has become a billionaire off the back of this boom.
Additionally, Chinese tech and entertainment giant Tencent snapped up 48.4 per cent of Epic's shares for $330m back in 2012. That stake will now be worth in the region of $4.1bn.
At last report, Fortnite had been played by a massive 125m people at the start of 2018 - meaning it's likely much higher at this point - with research firm SuperData reporting that users around the world had spent a total of $300m in the game in May 2018.
“On the revenue side, they’ve done something that’s really unique, which is come up with a perception of exclusivity,” said Wedbush Securities analyst Michael Pachter.
“If you see another player in a leopard skin and go to the store and see it’s no longer available, you think, Shoot, I’ve got to move on it next time.”
