Alphabet shares jump close to 7% in morning trade to an all-time high after Google presented its latest model of artificial intelligence, Gemini 3. It marked the largest single-day gain for the company in two months and outperformed the broader market amid growing investor optimism over Google’s AI progress.
Industry experts and analysts praised Gemini 3’s performance; Bloomberg described the reaction as ‘overwhelmingly positive’. This is in contrast to the mixed reception received by OpenAI’s GPT-5 earlier this year. Colin Sebastian of Rober W Baird and Company added that the Gemini 3 launch, backed by strong early testing and reviews, gave investors the breakthrough they were hoping for.
After the introduction of Gemini 3, Loop Capital raised Alphabet's rating to ‘buy’, based on enhanced faith in Google’s AI tactics. Heavy trading and positive comments from the analysts show the investors' general sentiment about the company.
Alphabet’s stock outpaces the NASDAQ 100, returning over threefold of the NASDAQ 100’s gain this year. This is a true testament to market confidence, not only in Gemini 3 but also in Google leading the AI race. Berkshire Hathaway further fueled the momentum by disclosing its stake purchase in Alphabet during Q3, a major vote of confidence by Warren Buffett.

Along with Gemini 3, Google also announced the release of Nano Banana Pro-image generation model, the newest version of its popular Nano Banana, aka Gemini 2.5 Flash. It brings advanced image creation and editing capabilities powered by Gemini 3.
Alphabet CEO Sundar Pichai termed Nano Banana Pro ‘state-of-the-art’ in generating images with improved world knowledge, text rendering, precision, and controls.
Nano Banana Pro is particularly good at creating complex, context-rich imagery like product prototypes, infographics, and even converting handwritten notes into diagrams.
