Alphabet (Google)

Alphabet, the parent company of Google, commands a market cap of approximately $2.4 trillion, powered by the world's most-used search engine, YouTube, and the Google Cloud Platform. After an initially rocky reception to its Gemini AI model, Alphabet regained its footing in 2025 as Gemini Ultra powered significant upgrades to Search, Google Workspace, and Google Cloud's enterprise AI services. Google Search still processes over 8 billion queries per day and remains the company's primary revenue engine. Despite a market cap that is 23% lower than #3 Microsoft, Alphabet's ad revenue grew by 12% in 2025, outpacing the average growth of digital advertising competitors by 4 percentage points.
