Fewer than two weeks after it hit iOS devices as an invite-only "event" and only 10 days after it began offering cosmetic in-app purchases to players, Fortnite from Epic Games has grossed approximately $5.3 million worldwide, according to Sensor Tower Store Intelligence estimates.
The chart below shows how this compares to the first 10 days of gross revenue from Fortnite's largest monetizing competitors, Knives Out and Rules of Survival, both published by NetEase. Note that their figures are for iOS only and the same countries where Fortnite is currently available, i.e., revenue from China is not included in their totals.
Fortnite currently ranks in the top 10 for overall iPhone revenue in three countries: Switzerland (No. 2), Luxembourg (No. 6), and the United States (No. 7). It's in the top 100 in another 28 countries, but in Japan, where Knives Out is currently the No. 4 grossing app overall, it's all the way down at No. 498.
Meanwhile, the world's current mobile battle royale download king, Tencent's PUBG Mobile, has yet to begin monetizing. Fortnite has surpassed its monthly microtransaction revenue on console and PC, so it should be interesting to see how the two games stack up on mobile once both are offering items for purchase.
