Google has launched its updated Google Finance service in France, following an initial rollout in the United States during the summer of 2025 and a global expansion to over 100 countries by spring 2026. The French version of the service is built on a tool previously tested in other regions, adapted to include local market data and translated into French. At the core of the new experience is the Gemini AI model, which powers a feature called Deep Search. This function allows users to ask complex financial questions, such as "how does the rise in interest rates affect technology stocks," and receive detailed, sourced answers within a few minutes. Deep Search works by performing hundreds of searches in parallel and then compiling a summary with a clear explanation of its search process. The new Google Finance platform is free to use and accessible through Google Search. However, some of the most powerful features, like Deep Search, are limited in usage for free users. Subscribers to Google AI Pro and Google AI Ultra, which are paid versions of Google's AI services, get higher usage limits. Users can manage their investments through a single dashboard, with detailed insights into their portfolio distribution. Visual tools such as graphs provide technical indicators and highlight "key moments" that explain daily stock price movements. The service also includes an upgraded news feed, expanded data on commodities and cryptocurrencies, and live updates on company earnings, including audio of conference calls, synchronized transcripts, and AI-generated summaries. Google aims to make financial information more accessible to people who might feel intimidated by traditional stock charts or financial jargon. However, the company emphasizes that its generative AI is still in an experimental phase. It can occasionally make errors, misinterpret data, or simplify information to the point of losing important details. As a result, Google advises users to double-check AI-generated responses before making financial decisions based on them. A mobile application for Google Finance is currently available only on Android devices, with an iOS version expected later in 2026. While Google Finance is entering a competitive market, it is not the first to offer similar tools. Neobanks like Revolut and Trade Republic already provide users with investment tracking and trading features within their apps. The key difference is that Google Finance focuses on information rather than allowing direct trading. In the same space, Yahoo Finance has long been a major player, offering stock prices and news. However, Google is differentiating itself by relying on its Gemini AI to process and synthesize financial information, rather than simply aggregating it.
