By 11 October 2026 Anthropic had not narrowed who can use Claude beyond account bans; its 8 October policy change only banned abusive behaviour towards Claude, The Guardian reported, which limits conduct, not access.
The access market resolves YES if Anthropic publishes between 11 September and 11 October 2026 a restriction on who may use a Claude model, meaning a country or region block, a new identity or organisation verification requirement, or the withdrawal of a model or capability from general availability, recorded on anthropic.com, in its usage policy or in its transparency reporting. Banning named accounts, adding classifiers and publishing further threat reports do not count, while a restriction Anthropic announces under a government order does; if the company publishes nothing, the Financial Times and Reuters reports of its access rules on that date settle it.
We found seven such reports since February 2024. In each, a leading AI developer said publicly that state-linked or armed groups had used its own model for attacks or weapons work. We checked whether, within 30 days, the developer limited who may use the model: by blocking a country or region, by asking users or organisations to prove who they are, or by taking a model or feature off general release. Banning the named accounts and adding filters did not count.
