Google's parent company Alphabet Inc (GOOGL.O) is reported to have generated $11.2 billion in revenue in 2019 through the Google Play Store app store.
This figure was revealed for the first time in a trial in which Google was sued for alleged antitrust violations on its app store.
The attorney general for Utah and 36 other US states that sued Google for alleged antitrust violations with app stores also said in a new filing that the business in 2019 had a gross profit of $8.5 billion and operating income of $7 billion for an operating margin of more than 62%.
The figure includes app sales, in-app purchases, and app store ads. Google told Reuters the data was used in an unsubstantiated lawsuit.
The company and its plaintiffs said in separate filings on Saturday, a trial in late 2022 was possible as to whether Google abused its alleged monopoly in the sale of apps for Android devices.
In its quarterly financial disclosures, Google grouped Play app revenue with other services and accounted for store ad revenue as part of another broader category.
The attorney general, as well as mobile app developer Epic Games and others separately sued Google, argued that it made a huge profit through the Play Store by taking 30% of the cost for every digital item sold in the app.
The plaintiffs say Google's cuts are so high that it sucks app developers' profits.
Google argues that there are alternatives to Google's stores and payment system, although critics say those routes are not viable and are sometimes blocked.
The plaintiffs allege that Google through anti-competitive deals extended benefits and imposed restrictions on major developers such as League of Legends creator Riot Games to prevent them from leaving the Play Store.
A filing by Epic Games that opened this month says Google, according to internal documents, is concerned about losing $1.1 billion in annual app store profits if the Play Store is successfully bypassed.
