Immediate Context and AI Innovation

The immediate context largely explains the stock's progression. Google announced on Wednesday the launch of Gemini 3, its new generative artificial intelligence platform. The model offers enhanced capabilities in reasoning, multimodal processing, and autonomous task execution. It features a context window reaching one million tokens, allowing for a deeper understanding of text documents, images, and videos. Gemini 3 integrates directly into Google Search, the Gemini app, developer tools, and the group's Vertex AI platform. This announcement is part of a cycle of strong results for Alphabet. The group reported a record third quarter with revenue of $102 billion, up 16% year-over-year. Operating margins have improved, driven by stable advertising demand and the ongoing expansion of cloud services. Analysts highlight that Gemini 3 could accelerate the adoption of AI among consumers and businesses, two strategic segments for the group. The stock also approached the psychological barrier of $300, establishing unprecedented levels during intraday trading. This progression is accompanied by an upward reevaluation by analysts. Loop Capital notably upgraded its rating on Alphabet to 'strong buy'. These movements reflect the market's confidence in the group's growth prospects in artificial intelligence and cloud services. Alphabet has thus accumulated more than 50% gains since the beginning of 2025, benefiting from the interest in its technological innovations.
