In less than a week, Fortnite has become a bona fide sensation on mobile, topping the iPhone download charts in more than 40 countries despite still being invite-only. Now, thanks to Sensor Tower Store Intelligence data, we have a first measure of how successful the game has been so far on the revenue front. According to our estimates, Fortnite has already grossed more than $1.5 million worldwide on iOS, with $1 million of that earned during the first 72 hours after IAPs went live. This places the game well ahead of its primary rivals in the burgeoning mobile survival game genre during the same post-launch period.
As the chart above illustrates, Fortnite has out-grossed NetEase’s Knives Out and Rules of Survival by a factor of more than 25 in its first four days of IAP availability, compared to the same period after both those titles began monetizing.
Fortnite’s revenue is also impressive when put into perspective against some of the largest mobile game launches from the past two years. Purely based on cosmetic IAP, it has managed to gross about one third as much as both Pokémon GO ($4.9 million) and Clash Royale ($4.6 million) made in their first four days of availability on iOS. We’ll have more on the game’s launch as it progresses.
