Token-based billing exposed AI's ROI problem: what the real numbers say

In Q1 2026, OpenAI and Anthropic shifted enterprise customers from flat-rate plans to token-based billing, making AI costs transparent for the first time. This exposed significant overspending: Uber consumed its entire annual AI budget in four months after encouraging unlimited use of agentic tools like Claude Code and Cursor. The company responded with a $1,500/month cap per employee for such tools. Brex limited engineers to $500/week in tokens and non-engineering staff to $5/week. T-Mobile temporarily capped usage at $2,000/month per user, planning a tiered system. An unnamed company reportedly spent $500 million on Anthropic models in a single month due to absent spend controls. A KPMG survey reported by the Wall Street Journal highlighted these trends, reopening the debate on whether AI delivers measurable ROI.
