Message from the CEO

“Behind every Wikipedia article, every edit, and every fact is a human story of dedication, passion, and generosity.”

Maryana Iskander
CEO of the Wikimedia Foundation

This year, the Wikimedia Foundation celebrated the idea that “Knowledge is Human,” from recognizing the hundreds of thousands of humans who contribute free and reliable knowledge, to highlighting the essential role that humans will always play in our approach to artificial intelligence. Behind every Wikipedia article, every edit, and every fact is a human story of dedication, passion, and generosity.

This Annual Report for our 2022-2023 fiscal year spotlights the countless individuals who work tirelessly behind the scenes to make Wikimedia projects the success that they are today – at a time when the world needs access to reliable information online more than ever before. 

You will read about students and teachers learning about the value of Wikipedia in the classroom, to medical professionals committed to producing health and science articles that are accurate and up to date. Our donors are critical to preserving the mission of Wikipedia, and our staff remain fiercely dedicated to supporting an open platform that thrives thanks to volunteer contributors across the globe. Each story in this year’s Annual Report is a window into the human effort behind a Wikipedia article and its impact. 

As you read this report, I hope you will join me in celebrating this generous community of humans. At a time when technology is changing so rapidly around us, Wikipedia is becoming an even more valuable source of trusted information to everyone, everywhere. For free. 

I am more inspired than ever before that together we can secure the future of Wikipedia for generations to come. 

Thank you for your unwavering support.

A global community of people help the Wikimedia projects to thrive

For more than two decades, the process of freely creating knowledge — of sharing it and refining it over time, in the open, and with the help of hundreds of thousands of volunteers — has fundamentally shaped Wikipedia. Wikipedia contains trustworthy, reliably sourced knowledge because it’s created, debated, and curated by people. It’s also grounded in an open, noncommercial model, which means that Wikipedia and all Wikimedia projects are free to access and share, and always will be. In an internet flooded with machine-generated material the human-led content on Wikipedia has become even more valuable.

That value was apparent throughout the Wikimedia Foundation’s 2022-2023 fiscal year, when a global community of people — editors, writers, technical volunteers, and staff — made sure the Wikimedia projects thrived. They added new knowledge to the websites. They kept the websites operating at the highest levels. And they helped people to gain new knowledge, one edit at a time.

In this Annual Report, you’ll meet doctors from across the world who made sure that Wikipedia’s thousands of medical articles were accurate, current, and correctly sourced. You’ll meet teachers and students who use Wikipedia to learn and explore our world. You’ll meet two donors who believe that Wikipedia’s ability to provide quickly accessible knowledge is changing the world for the better. And you’ll meet engineers at the Wikimedia Foundation who improved the platform’s technical infrastructure to make it easier for everyone to access the Wikimedia projects from anywhere in the world.

We look back on this past year with inspiration and a sense of accomplishment. We think you will, too.  Thank you for being an essential part of our mission to bring trustworthy knowledge to everyone, everywhere.

Financial Accountability

Navigating the Numbers

Accountability and transparency are two principles that underpin the Wikimedia Foundation’s core values. We are committed to managing funds and resources so that every contribution furthers our mission of advancing knowledge for all.

In recognition of how we operate, we’ve been honored with the Platinum Seal of Transparency from Candid (formerly GuideStar), and Charity Navigator has awarded us their highest rating of four stars.


Nearly half of our budget is used to support the technology that makes Wikipedia and other Wikimedia projects possible. We continually work to improve the user experience for contributors and readers; enhance security for the sites; and ensure reliable, consistent access to the websites around the world. We provide this infrastructure and product support for one of the top ten most popular websites in the world at a fraction of the cost of popular for-profit websites.

The global impact of Wikimedia projects is made possible by the dedicated efforts of volunteers from around the world. We provide grants, legal assistance, and other resources for our contributors to build thriving volunteer communities. Additionally, we encourage community engagement through outreach events and advocate for the growth and protection of free knowledge.

Donor support forms the lifeblood of Wikipedia and our other free knowledge initiatives. Our team works tirelessly year-round to fundraise efficiently and effectively, ensuring that every contribution sustains our mission.

Operational costs are necessary for the effective management and governance of the Wikimedia Foundation. These administrative and people-related costs allow us to hire the best talent and support staff around the world to carry out the mission of the Wikimedia Foundation.

Wikimedia Endowment

Sustaining Impact

The Wikimedia Endowment launched in 2016 with an aim to create a permanent fund to support Wikipedia and other Wikimedia projects, sustaining our mission well into the future. This year, the Endowment reached an important milestone: a portion of its investment income was used to support the technical innovation of the Wikimedia projects. In a series of interviews with Endowment donors, we heard repeatedly about the desire to use their donations to support technical innovation to keep the Wikimedia projects relevant in a rapidly evolving world.

The focus on technical innovation also supports the Endowment’s long-term vision for maintaining the projects, including sustainable technical infrastructure. The projects chosen align with current and existing work being done to improve and innovate on Wikimedia projects in collaboration with volunteers. The recipients are:

Abstract Wikipedia aims to build a knowledge base independent of language, making it easier to share, add, translate, and improve knowledge across languages on Wikipedia. Wikifunctions is the underlying technical infrastructure that supports the project. Abstract Wikipedia’s technical development is led by the Wikimedia Foundation.

Kiwix is a non-profit that provides an offline reader for Wikipedia content, making knowledge more accessible to people around the world regardless of internet connectivity. Kiwix has over 10-12 million users spanning 200 countries.

Led by the Wikimedia Foundation’s Machine Learning team, this programmatic area of Wikimedia work focuses on building and strengthening AI and machine learning infrastructure on the Wikimedia projects. Machine learning tools make the work of volunteer editors more efficient, enabling them to focus time on edits that require complex human judgment. This work includes the development of algorithms to measure the quality of Wikipedia articles and machine learning models that help catch incidents of vandalism on Wikimedia projects.

Wikidata is the multilingual, structured knowledge base that powers knowledge on Wikipedia. With more than 100 million data items, it is the most edited Wikimedia project. Wikidata more easily connects knowledge from Wikimedia projects with machines, including voice assistants, websites, and other platforms that leverage Wikimedia content. The Endowment grant will fund the existing multi-year plan for the project, which is led by Wikimedia Deutschland in collaboration with the Wikimedia Foundation.

We are excited to see how Abstract Wikipedia, Kiwix, Machine Learning, and Wikidata strengthen our technical infrastructure and innovation.
