A note on the separate status of the Wikimedia Endowment
The Wikimedia Endowment, held from 2016 to 2023 by the Tides Foundation and now a standalone 501(c)(3) nonprofit, is not and has never been included in Wikimedia Foundation assets, even though Wikimedia Foundation fundraising staff solicit donations to the Endowment and the Wikimedia Foundation itself made donations to the Endowment.[1]
The Endowment was set up in 2016 and was originally expected to reach $100 million in 2026; it reached the target five years sooner than expected.
- ^ "The Foundation has an agreement with the Tides Foundation that established the Wikimedia Endowment as a Collective Action Fund to act as a permanent safekeeping fund to generate income to ensure a base level of support for the Wikimedia projects in perpetuity. The Endowment is independent from the Foundation. From fiscal years ended June 30, 2016 through June 30, 2021, the Foundation provided irrevocable grants in the total amount of $30 million ($5 million per fiscal year) to the Tides Foundation for the purpose of the Wikimedia Endowment. The amounts are recorded in awards and grants expense." Quoted from Financial Statements 2021/2022, p. 15.
