.org domain, explained
Public Interest Registry, a nonprofit created by the Internet Society, has operated .org since 2003. There is no eligibility test, but the extension's reputation shapes who buys: nonprofits, associations, foundations, open-source projects, communities and companies that want a public-interest feel. According to the Domain Name Industry Brief, .org was among the ten largest TLDs by registrations at the end of the second quarter of 2026.
For an investor, .org is a narrower market than .com. The strongest names are single words and short phrases tied to causes, professions, sciences and communities, and many of their buyers work with smaller budgets than commercial companies, so expect lower prices and longer holds. Avoid .org versions of company brands, which carry trademark risk and have few legitimate buyers. Watch the renewal fee as well: the 2019 .org registry agreement dropped the earlier cap on price increases, so the cost of a long hold can rise.
Example. An investor holding a one-word .org for a scientific field markets it to professional associations and research groups, and prices it below what the matching .com would command.
