The European Union is investigating whether Google's agreement with Samsung restricts the availability of rival chatbots on Samsung smartphones.

Google contends that breaking up its business would hinder AI development and innovation, particularly as it competes against technological advancements from China.

As of March 2025, Google's AI platform Gemini boasts 350 million active monthly users, with 35 million engaging daily, a notable increase from 90 million monthly users and 9 million daily users in October 2024.

During the trial, it was revealed that Google has a two-year agreement with Samsung, involving substantial payments for pre-installing Gemini on Samsung devices, indicating a strategic partnership.

Despite this growth, Gemini still lags behind competitors like OpenAI's ChatGPT, which has around 600 million monthly active users, and Meta AI, which is nearing 500 million.

The ongoing antitrust trial is scrutinizing Google's search monopoly, with potential outcomes including significant changes to its business practices, such as divestitures of its Chrome browser.

Gemini's rapid user adoption is attributed to its deep integration into Google's services, including Samsung devices, Google Workspace, and the Chrome browser.

Regulatory concerns have emerged regarding Gemini's integration, as the U.S. Department of Justice argues it could extend Google's dominance into the AI sector and stifle competition.

The trial highlights the broader implications of Google's practices on competition in the online search market, with the U.S. Justice Department advocating for a breakup to foster a more competitive environment.

In response to regulatory scrutiny, Google proposed a three-year plan to allow more flexibility for partners in distributing the Gemini Assistant chatbot in the U.S.

Google has introduced advanced features for Gemini, including a video generation model called Veo 2 and AI-generated podcasts, enhancing its competitive edge against ChatGPT.

A ruling from U.S. District Judge Amit Mehta is expected by the end of summer 2025, following a three-week hearing focused on potential penalties for Google.
