Alphabet shares climbed 65.4% over the course of 2025, handily surpassing the S&P 500’s 16.4% gain and matching only by Nvidia among the so-called Magnificent Seven. This rally reflected strong revenue growth in core advertising and cloud services, where Alphabet expanded search ad impressions by 18% year-over-year and grew Google Cloud revenue by 45% in the fourth quarter. Analysts highlight that Alphabet has successfully integrated generative AI capabilities into its search engine without cannibalizing existing ad monetization, setting the stage for sustained top-line acceleration in 2026 and beyond.
