Case study ix · OpenAI and Anthropic · AI Enterprise Contracts · Fixed Fee

Global bank renegotiates its AI vendor contracts. Dual-vendor strategy, $4.8M saved.

A global investment bank held OpenAI and Anthropic enterprise contracts signed in the 2024 procurement rush — $8.2M combined, both renewing within four months. The CIO wanted single-vendor consolidation on cost grounds; the CDO and Chief AI Officer wanted dual-vendor resilience and model diversity.

The lesson

What the case teaches.

AI contracts signed in 2023–2024 carry significant unrealised leverage at renewal: the market has matured faster than the paper. Buyers negotiating from usage data and competitive intelligence typically achieve 25–40% improvements.
