Alphabet and Amazon reported significant first-quarter profits, largely driven by gains from AI-related equity investments. Alphabet recorded $37.7 billion in "other income," representing over half of its net profit for the period. Amazon, alongside Alphabet, reported a combined $53 billion in "other income," which accounted for nearly 60% of their quarterly profits. This income primarily stems from changes in the valuation of equity holdings in private AI companies like OpenAI and Anthropic, where Alphabet is the largest investor and Amazon is a major stakeholder. The substantial contributions from these investments underscore the growing financial interdependence within the AI technology sector.
