Cosmos Club membership requirements

Every criterion Cosmos Club publishes, with its source, the date it was verified and how confident we are in it, plus superseded figures, so you can see how the tests have moved.

Read a requirement as the organization's published floor, not as a promise. A revenue test may have alternative versions for different business types, chapters can set stricter local tests, and invitation-only bodies publish criteria that describe members rather than admit them.
