Alphabet shares climbed more than 65% in 2025 after investors embraced the company’s turnaround from AI laggard to generative-AI frontrunner. The launch of Gemini, its advanced large language model, and the rapid deployment of AI-powered features in Search and Workspace drove revenue acceleration. In Q4 2025, Alphabet reported 23% year-over-year revenue growth in Google Cloud and a 19% rise in overall ad revenue, underscoring how AI innovation has translated into stronger monetization across its core businesses.

A decade of in-house chip development paid off as Alphabet’s Tensor Processing Units (TPUs) became central to its AI infrastructure strategy. By relying on its own ASICs rather than third-party GPUs, Alphabet avoided the so-called ‘Nvidia tax’ and achieved up to 30% lower per-training-run costs. In 2025, Google Cloud’s TPU revenue doubled, contributing $8.5 billion to the division’s top line and helping Cloud grow 40% faster than the industry average for hyperscale providers.

In late 2025, a landmark court ruling upheld Alphabet’s right to remain the default search engine on Chrome and Android devices, preserving an estimated $12 billion annual benefit in mobile search ad revenue. The decision removed a major regulatory overhang and cemented Google’s status as the primary internet gateway for more than 2 billion monthly active users, safeguarding the company’s dominant market position against rivals and potential policy changes.

Alphabet now trades at roughly 30 times forward earnings—broadly in line with peers—after its prior discount evaporated over the course of its 2025 rally. Wall Street consensus projects 12% annual EPS growth over the next three years, underpinned by further AI platform roll-outs, international ad market expansion, and ongoing Google Cloud momentum. While outsized short-term gains are unlikely at current multiples, investors can still expect mid-teens total returns driven by accelerating free cash flow and share-repurchase programs.
