Google reportedly paid Apple $20 billion in 2022 to be the default search engine on iOS devices, according to documents in the U.S. Department of Justice's antitrust lawsuit against Google. This amount has increased over the years, with previous payments being around $15 billion in 2021 and $10 billion in 2020.
Google's market share of search queries on iPhone is not explicitly mentioned in the provided text. However, it states that Google has managed to make some progress, with a low-30% number of Google Search queries on iPhone coming from the company's own apps, up from around 25% five years ago. Google's goal is to move 50% of searches on iPhone to its own apps.
Google is under antitrust scrutiny due to allegations of using its dominant position in the search engine market to stifle competition, through practices such as paying billions of dollars to be the default search engine on devices like Apple's iPhone and web browser such as Apple's Safari and Mozilla's Firefox. The U.S. government contends that these practices make it harder for people to find the best search results as quickly as possible and limit consumer access to competing technologies.
