Transparency is a core principle of the Wikimedia Foundation, and we are proud to be recognized as one of the most transparent non-profit organizations in the world. Our annual plan and operating budget are developed through open processes, subject to community feedback and Board approval, and always available to the public for full review.

We show our financial activity in three key areas of effort: how donor contributions support the Wikimedia websites, the Wikimedia community, and the free knowledge ecosystem.

These efforts are supported by our organization’s administrative and fundraising activities.

Direct support to websites

Keeping the Wikimedia websites online is about more than just servers. It also includes ongoing engineering improvements, product development, design and research, and legal support.


Direct support to communities

The Wikimedia projects exist thanks to the communities that create and maintain them. We strengthen these communities through grants, projects, trainings, tools to augment contributor capacity, and support for the legal defense of editors.


Administration and governance

We manage funds and resources responsibly to recruit and support skilled, passionate staff who advance our communities and values.


Support of free knowledge

Wikimedia is part of a larger free knowledge movement. Part of our operating expenditure supports policy, advocacy, education, and partnerships to strengthen and further access to open knowledge.



Wikimedia is supported entirely by donations. The fundraising team engages with millions of remarkable individuals and institutions to ensure that we have the necessary resources to continue our global mission.
