Vendor Lock-In

Vendor lock-in describes the situation where an organization becomes so dependent on one AI provider's models, platform, or proprietary tools that switching to another provider becomes costly, slow, or technically impractical. For AI governance teams, it matters because lock-in can limit leverage in contract negotiations, expose the business to sudden price increases or service changes, and make it harder to meet obligations such as data portability, audit access, or exit planning. Compliance and risk leaders typically address it through contract terms, multi-vendor architecture, and documented exit strategies.

HHS Sole-Source Anthropic Award Puts AI Vendor Lock-In Under Federal Scrutiny

The U.S. Department of Health and Human Services disclosed its intent to award Anthropic a sole-source contract for Claude AI services, citing its existing enterprise deployment as justification. A government procurement law expert challenged the notice as an admission of vendor lock-in rather than a legitimate sole-source basis. The case is now a named federal example of the concentration and dependency risks that enterprise AI procurement programs must actively manage.
