AI supply chain term

TCO (Total Cost of Ownership)

TCO is the full lifetime cost of running AI compute — hardware, power, cooling, networking, real estate and financing — not just the sticker price of the chips.

What it means

TCO (Total Cost of Ownership) is the total cost of owning and operating AI infrastructure across its useful life. For an AI data center that means the capital cost of GPUs and servers plus the ongoing bills for electricity, cooling, networking, real estate, maintenance and financing. Electricity price — the cost per kilowatt-hour — is one of the largest recurring inputs, and it propagates upward into cost per token and application margins. TCO sits at the economics layer of the AI supply chain: it is where chip prices, power prices, utilization and depreciation combine into the single number that decides whether an AI service is profitable. Because power and hardware depreciation dominate the total, small changes in energy price or GPU useful life swing TCO a lot — making it both a constraint on margins and a lever for anyone who can secure cheaper power or higher utilization.

Why it matters to investors

TCO decides who captures the economics of the AI trade. Operators that lock in cheap, reliable power and keep expensive hardware highly utilized run the lowest cost base, while those exposed to volatile electricity prices and fast depreciation see margins squeezed.
