Capex vs. Opex in AI
The distinction between capital expenditure (buying GPUs, building data centers) and operational expenditure (cloud API costs, ongoing compute) in AI deployment, shaping business strategy and financial planning.
Big Tech companies are spending $650+ billion in AI capex for 2026, buying GPUs and building data centers as capital assets. In contrast, most enterprises consume AI through operational expenditure — cloud API pricing and SaaS subscriptions. Cloud AI API costs have dropped 280x in 18 months, shifting the economics toward opex. Companies must choose between investing in owned infrastructure (higher upfront cost, lower per-unit cost) and cloud consumption (lower risk, higher per-unit cost). The capex-heavy approach of hyperscalers creates a massive infrastructure moat.

AI Compute
The computational resources — primarily GPU and TPU processing power — required to train and run AI models, typically measured in FLOP (floating-point operations) or GPU-hours.
Capex (Capital Expenditure)
Long-term investment spending by companies on physical assets like data centers, GPU clusters, and networking infrastructure — the backbone of AI deployment at scale.
Data Center
A facility housing computer systems and infrastructure used to process, store, and distribute data — increasingly built specifically for AI training and inference workloads.
Enterprise AI Adoption
The rate at which businesses integrate AI technologies into their operations, measured across functions like customer service, software development, marketing, and supply chain management.
Fine-Tuning
The process of further training a pre-trained AI model on a specific, smaller dataset to specialize it for a particular task or domain, requiring far less compute than training from scratch.
Foundation Model
A large AI model trained on broad data that can be adapted to a wide range of downstream tasks — examples include GPT-4, Claude, Gemini, and Llama.
