Access to knowledge is a fundamental human right. The Wikimedia Endowment is our enduring commitment to a world of freely shared knowledge, now and in perpetuity.
We believe that knowledge is a foundation. It is a foundation for human potential, a foundation for freedom, a foundation for opportunity. Wikipedia is the world’s largest free knowledge ecosystem — a public trust for the common good — built by people, for people.

Like other public trusts, such as universities and libraries, the Wikimedia Foundation is caretaker of an immense repository of knowledge—and thereby humanity and culture—with the imperative of increasing and ensuring access for all.
The Wikimedia Endowment will conserve and expand the world’s largest free knowledge ecosystem. We strongly believe that the Endowment is not only a necessary safeguard for the millions of articles, media, and resources created by Wikipedia contributors, but also a springboard for innovating the way we curate and deliver knowledge to the world.
Building the Wikimedia Endowment includes long-term strategic planning and investment in the Wikimedia vision, Wikipedia, the Wikimedia Foundation and our volunteers, donors, partners and affiliates around the world. When we reach our initial funding goal of $100 million, Wikimedia Endowment income will help realize a world in which every single human being can freely share in the sum of all knowledge.
"Wikipedia stands alone in the online world, providing information and knowledge to anyone, anywhere, without cost."— Annette Campbell-White, Wikimedia Endowment Advisory Board Member
Wikipedia was launched in 2001 with a big vision: “Imagine a world in which every single human being can freely share in the sum of all knowledge.” Now, with over 50 million articles in 300 languages and serving more than 500 million users every month, it is the only non-profit site in the top ten most visited on the web.
Wikimedia also supports a range of additional offerings to further enrich the commons, providing vital resources, knowledge and infrastructure.
A free and open storage for the structured data of all Wikimedia projects including Wikipedia, Wikivoyage, Wikisource, and others
A multilingual repository for free photographs, diagrams, maps, videos, animations, music, sounds, spoken texts, and other free media
"The Wikimedia Endowment is a springboard for growth and innovation in how we curate and deliver knowledge to the world for generations to come."— Jimmy Wales, Wikipedia Founder and Wikimedia Endowment Advisory Board Member
The Wikimedia Endowment Advisory Board – comprised of leaders from finance, education, technology, and business – is guiding the endowment as it grows and supports the Wikimedia projects in perpetuity.
