Alphabet dominates global search with 91% market share and runs the world's largest digital advertising platform, generating $307 billion in revenue from businesses that pay to reach its 4 billion daily users. The company's moat stems from proprietary data advantages that improve ad targeting accuracy and search relevance with every query, creating a self-reinforcing cycle competitors cannot replicate. Google Cloud revenue surged 35% last quarter to $11.4 billion, finally gaining meaningful traction against AWS and Azure in the $500 billion cloud infrastructure market. At 25x forward earnings, shares trade at the lowest valuation in five years despite 18% revenue growth and 35.7% ROE, while the company sits on $111 billion in cash to fund AI investments that should accelerate both search innovation and cloud adoption.
