Alphabet Surges Past Amazon on AI Race

Alphabet has emerged as a top performer in the mega-cap tech sector for 2025, with its stock price climbing nearly 60%. This impressive growth is attributed to a significant shift in investor sentiment, rebranding the company from an AI laggard to a potential leader. Key to this transformation are its Gemini foundational large language model and proprietary artificial intelligence chips.

The Gemini model has been integrated across Alphabet's products, notably enhancing its core search business with features like AI Overviews. Concurrently, its custom Tensor Processing Units are gaining recognition as a strong alternative to Nvidia's GPUs. These chips are crucial for Alphabet's internal operations, providing a cost advantage and attracting external commitments, such as Anthropic's $21 billion purchase agreement.

In contrast, Amazon's performance has been more modest, with AWS trailing competitors in growth. However, AWS recently reported a 20% revenue acceleration and indicated capacity limitations. In response, Amazon is substantially increasing its capital expenditure to meet the escalating demand for its cloud services in the coming year.
