Alphabet (GOOG) (GOOGL) touched a market capitalization of $4T on Monday, riding a wave of AI boom.
Last week, Google surpassed Apple (AAPL) in market cap for the first time since 2019, becoming the second most valuable company in the world.
In the past one year, Alphabet’s stock has surged about 70%. In the last one year, the company has seen its AI service Gemini doing well, while also seeing a vital win in a Department of Justice, or DOJ, case.
Last month, Google globally launched its latest AI model called Gemini 3 Flash, making it the default model in the Gemini app, replacing 2.5 Flash. The November 2025 launch of Gemini 3 had caused renewed enthusiasm for Google among investors, organizations, and the broader tech community. Last week, analysts at BNP Paribas noted that even though OpenAI’s (OPENAI) ChatGPT is still more widely used, the gap between the two is closing fast.
Reportedly, Samsung Electronics (SSNLF) is planning to double the number of its mobile devices powered by Gemini in 2026.
On Monday it was reported that Apple (AAPL) has chosen Google’s Gemini AI models to run its next version of Siri. Last month, Wedbush (IVES) highlighted its top 10 tech predictions for 2026, which included Apple (AAPL) and Google announcing a formal AI partnership around Gemini.
In September, Alphabet’s stock had a major overhang removed after a federal judge ruled that the U.S. tech giant won’t be forced to sell its flagship Chrome web browser. The decision had seen positive reactions from analysts.
