AI Costs Are the New Cloud Costs

The fastest-growing line item nobody's tracking

In 2023, most enterprises had near-zero AI spend. By mid-2025, the average mid-market company was running $500K+ annually across ChatGPT licenses, Copilot seats, API calls, and a growing list of point solutions. That's a trajectory that makes the early cloud adoption curve look gentle.

Cloud infrastructure took roughly a decade to go from experimental to the second-largest IT line item. AI is doing it in under two years. And unlike the early days of cloud, where at least someone in IT was provisioning the servers, AI adoption is happening everywhere at once — with nobody aggregating the bill.

Shadow AI is the new shadow IT

Here's what we're seeing in the field right now: a marketing director expenses a ChatGPT Team subscription on a corporate card. An engineering lead signs a Copilot Enterprise agreement through their existing GitHub contract. A data science team spins up an OpenAI API account on a departmental AWS bill. A product manager puts Claude Pro on their personal expense report.

Nobody in finance, procurement, or IT has a complete picture. There's no centralized procurement process because AI tools don't look like traditional software purchases. They're $25/seat subscriptions that start small and grow fast, or API accounts that bill by the token with no ceiling.

When we run AI spend analysis for clients, the total is almost always 2–3x what leadership thought they were spending. Not because anyone is hiding anything — because nobody is looking.

The overlap problem

Lack of visibility creates a second problem: redundancy. We routinely find organizations paying for four or five AI tools that do substantially the same thing.

• Two different teams paying for ChatGPT Enterprise and Claude Team for the same use case — internal content generation
• Engineering running both Copilot and a separate code-completion tool with overlapping functionality
• Customer support using one AI assistant while the product team builds another from scratch using API calls
• Multiple departments each paying retail for tools that could be consolidated under a single enterprise agreement at 30–40% lower cost

This isn't a technology problem. It's a procurement problem. Nobody has inventory, so nobody can spot the overlap.

The forecasting problem

Cloud costs are hard to forecast. AI costs are harder. At least with cloud, you can look at historical compute usage and project forward. With AI, you're dealing with consumption-based pricing where a single team's API usage can spike 10x in a month because they deployed a new agent or changed a prompt that increased token counts.

The pricing models don't help. Per-seat licenses look predictable until you realize departments are adding seats without approval. API-based billing is completely variable. And hybrid models — where you pay per seat for the interface and per token for the API — mean a single vendor can show up on your books in two completely different cost categories.

Finance teams that spent years building cloud cost models are starting from scratch with AI. The tools, the data, and the institutional knowledge don't exist yet.

Cloud costs took 10 years to get FinOps. AI can't wait that long.

The cloud cost management discipline — what the industry calls FinOps — emerged slowly. Companies spent years overpaying before the tooling and practices caught up. The industry collectively wasted hundreds of billions before someone said, "maybe we should track this."

AI costs are on the same trajectory but accelerated. The difference is that we now know what the playbook looks like. Visibility first: what are we spending, where, and with whom? Attribution second: which teams, projects, and use cases drive the cost? Optimization third: are we buying the right tools at the right tier with the right contract terms?

You don't need to wait for the industry to build new frameworks. The principles are the same ones that work for cloud — applied to a new category of spend.

Where to start

The first step is the same one that works for cloud: get a complete picture of what you're actually spending. Not what you think you're spending. Not what IT reports. The real number, across every team, every tool, every billing account.

Cloudsaver's free savings assessment now includes AI spend analysis alongside cloud infrastructure. We map your complete AI footprint — seats, API accounts, shadow subscriptions — and show you the overlap, the gaps, and the opportunities to consolidate.

The companies that get ahead of AI costs now will save millions over the next three years. The ones that wait will repeat every mistake the industry made with cloud — just faster.
