7 North American companies spending the most on AI
AI investments have become the defining business trend in North America. The largest spenders are no longer treating artificial intelligence as a software upgrade. They are funding data centres, chips, cloud capacity and foundation models at industrial scale.
1. OpenAI
OpenAI sits at the top because of Stargate, the AI infrastructure venture announced with an intended $500 billion investment over four years, beginning with $100 billion deployed immediately. The project is designed to build AI infrastructure in the United States and support OpenAI model training and inference.
2. Amazon
Amazon is one of the largest annual spenders. Its 2025 capital expenditure plan was expected to exceed $100 billion, with the vast majority directed toward AWS and AI capability. CEO Andy Jassy has linked the spending to demand for cloud based AI services and custom chips.
3. Microsoft
Microsoft committed about $80 billion in fiscal 2025 to AI enabled data centres, reinforcing Azure, Copilot and its OpenAI related ecosystem. Its spending reflects a clear enterprise strategy, with business AI positioned as a core driver of cloud growth.
4. Alphabet
Alphabet said it expected to invest about $75 billion in 2025 capital expenditure, mainly for technical infrastructure, servers, data centres and networking. Google Cloud, Gemini and search related AI features make this one of the most consequential AI investments in the market.
5. Meta
Meta raised its 2025 capital expenditure outlook to $64 billion to $72 billion, citing additional data centre investments to support artificial intelligence and higher infrastructure hardware costs. The company is spending heavily on Llama, AI assistants, advertising tools and smart devices.
6. Oracle
Oracle has moved from cloud challenger to AI infrastructure heavyweight. Executives said the company would spend roughly $50 billion in capital investments during its current fiscal year to expand cloud and AI compute capacity.
7. Anthropic
Anthropic is smaller than the hyperscalers, but its AI investment profile is rising quickly through major cloud and compute partnerships. Recent reports point to large funding rounds and expanded infrastructure commitments as demand for Claude grows across enterprise customers.
Why it matters
The AI race is now a capital spending race. For executives, the key question is no longer whether to adopt AI. It is which companies can turn infrastructure scale into durable margins, stronger customer products and defensible platforms. Stanford’s AI Index notes that business AI adoption is producing measurable savings, although many companies still report benefits below 10 percent.
