Google parent company Alphabet expects to invest approximately $75 billion in capital expenditures in 2025, according to a statement from CEO Sundar Pichai in Alphabets Q4 2024 earnings release.Capital expenditures have become a hot topic as of late as big tech companies race to build infrastructure to support their growing AI ambitions, and todays announcement from Alphabet is clearly meant to keep the company in that conversation. Alphabet spent $32.3 billion on capital expenditures in 2023, so $75 billion in 2025 would be a big jump. And while Googles press release today doesnt specifically say that the upcoming capital expenditures are all for AI, given the amount of money flowing into AI infrastructure across the industry, it seems likely that a good amount of the expense will go toward benefitting Googles AI work. AI continues to benefit Googles business as well. Overall revenues are up 12 percent year-over-year to $96.5 billion. Google Cloud revenues are up 10 percent to $12.0 billion, which Google says is led by growth in Google Cloud Platform (GCP) across core GCP products, AI Infrastructure, and Generative AI Solutions.During the quarter, the company made some big news about its AI products, including revealing Gemini 2.0, an AI agent called Project Mariner that can complete tasks in a Chrome browser, and its Deep Research tool that can research things on the web for you. It also demoed a new Android XR mixed reality OS.Alphabet-owned Waymo had a pretty good 2024 overall, though todays earnings report shows that Other Bets, which includes Waymo, had lower revenue and higher losses year-over-year.In Q4, the Department of Justice also proposed that Google potentially divest itself of Chrome as a remedy for Judge Amit Mehtas August ruling that the company is a monopolist in the search and advertising markets. The final outcome of those remedies could have a big impact on Google / Alphabets future.Alphabets investor call is happening now, and well update this story with anything notable from the call.
