Anthropic's terms update does something structurally different from a typical policy revision: it moves age and identity verification out of the optional-best-practice category and into a contractual obligation binding on every downstream user of the API. That means the compliance decision is no longer Anthropic's to make — it is the deployer's, and it must be made now. Developers building consumer products on Claude who have not implemented age gates face a terms violation, not a best-practices gap. Enterprise buyers who assumed their master agreements were stable will need to revisit them. The update surfaces as the latest in a pattern of unilateral policy tightening from Anthropic that distributes risk to customers rather than absorbing it centrally — and it lands while Claude's enterprise integration footprint is actively expanding, which makes the timing of the compliance requirement particularly sharp.
