What this gap means
robots.txt disallows both ChatGPT-User and Claude-User for the whole site, so neither assistant will open its pages for a user who asks.
Control: robots.txt verdicts for ChatGPT-User and Claude-User. Rule: blocks_assistants over the census record (reachable sites only). Who buys this: AI-visibility vendors and digital agencies: these sites are closed to ChatGPT and Claude users.
The obligation it maps to
robots.txt and AI crawlers (RFC 9309): robots.txt is voluntary and only tells well-behaved crawlers what to fetch. The census records what each bank asks of GPTBot, ClaudeBot, ChatGPT-User, Claude-User, Perplexity-User and Googlebot, and whether any AI crawler is named explicitly. Source

Atom feed: banks that entered or left this list according to the live re-checks (every 6 hours a rotating slice, each domain at most once per 14 days; each entry says which way it moved and which field changed). blocks-assistants.top.json: the first 50 rows and the counts by state as JSON, CORS open. Fields watched: robots, robots.ChatGPT-User, robots.Claude-User.
Membership reflects the homepage and well-known files as fetched on 2026-09-30: a control that exists but was not found where the census looked counts as missing, and sites answering 403 to our one polite request count as reachable. Every domain links to its record with what to fix, a JSON twin, a badge and a changes feed. Data licence CC BY 4.0. Not legal advice.
