The nine states known or widely assessed to possess nuclear weapons.

Membership of a cultural or political grouping is not always settled, and different sources draw the line in different places. Stating the rule up front is the point: it lets you judge whether this list answers your question, instead of wondering why a country you expected is missing. Every figure in the table comes from the dataset described on the data page.
