We believe in being open

The Wikimedia Foundation is a United States 501(c)(3) tax-exempt organization. Our mission to empower people worldwide to collect, develop, and share knowledge can only be achieved through a combination of trust and transparency. That is why we regularly share updates, including annual and biannual reports on our finances, content moderation requests, and more.
