Google's earnings report is a pivotal moment, especially as it reflects the company's commitment to AI and its ability to sustain its spending spree. The focus is on the company's AI pipeline, with the launch of cheaper Gemini models and the delay of the flagship Gemini 3.5 Pro AI model. This raises questions about the sustainability of long-term demand for AI, as well as the competition from cheaper Chinese models and the rising costs of tokenization. The company's search business is expected to hit $63.4 billion, with YouTube advertising revenue and cloud revenue estimated to reach $10.8 billion and $22.3 billion, respectively. Google's cloud business has posted robust growth in recent quarters, outpacing rivals like Amazon and Microsoft. The acquisition of cloud security company Wiz and the deal with SpaceX for AI compute capacity are boosting cloud growth. However, the company's stock is facing a decline due to AI skepticism, with the company behind Apple and Nvidia for the year. The focus on AI spending is a key concern for investors, with Alphabet's capital expenditures skyrocketing in recent quarters. The consensus estimate for Alphabet's 2026 capex is $187.1 billion, with Amazon expected to spend more. The company's finance chief has warned that 2027 capex is likely to significantly increase, with analysts estimating a figure of $262 billion. The company's spending spree is a testament to its commitment to AI, but it also raises questions about the sustainability of its long-term growth.
