Woofun AI reports that Google Cloud product revenue is now primarily driven by TPU system sales, establishing TPUs as a significant income source. In the current quarter, cloud business profit growth significantly outpaced revenue growth, indicating that AI infrastructure investments are generating high capital returns. The quarterly capital expenditure of $44.9 billion is projected to support revenue and cash flow contributions in coming years, with spending levels expected to remain high amid sustained demand. Market attention is shifting from search advertising to a valuation framework centered on AI investment capital requirements and after-tax cash returns, while progress on the Gemini large model and Agentic Coding products remains a key focal point.
