The Open Society Foundations (OSF) is a US-incorporated 501(c)(3) private grantmaking network headquartered at 224 West 57th Street in New York and operating globally through offices in Africa, Asia Pacific, Europe and Central Asia, Latin America and the Caribbean, the Middle East and North Africa, and the United States. It describes itself as "the world's largest private funder of independent groups working for rights, equity, and justice," and reports $1.2 billion in 2024 expenditures, $24.2 billion in cumulative grantmaking to date, and an average 10.2% annual increase in expenditure since 2016. The Foundations were established in their current US form in April 1993 as the Open Society Institute, building on George Soros's prior philanthropic infrastructure — the Soros Foundation/Budapest (1984) and a wider eastern- and central-European network established through the late 1980s and early 1990s — and were renamed the Open Society Foundations in 2010. Soros has given more than $32 billion of his personal fortune to OSF over its lifetime, including a $18 billion transfer in 2017 that consolidated his philanthropic commitment into the Foundations' endowment; OSF reports total assets of approximately $23 billion. Alexander Soros chairs the Board of Directors; Binaifer Nowrojee took over as President on 1 June 2024, succeeding Mark Malloch-Brown (2021–2024) and becoming the first woman from the Global South to lead the network; Nowrojee was previously OSF's Vice President of Programs, East Africa Foundation Director, and Asia Pacific Regional Director, with earlier roles at Human Rights Watch and the Lawyers Committee for Human Rights.
OSF's structural shape is unusual within the funder slice of this corpus. Unlike the Ford Foundation or the MacArthur Foundation, which are US-headquartered endowed foundations with international programmes, OSF is itself a network of regional and thematic foundations operating with substantial decentralised authority; unlike the Nuffield Foundation it is global rather than national, and unlike the Mozilla Foundation it is not anchored in a parallel commercial-technology nonprofit. The closest structural analogue in the funder slice is the African Digital Rights Fund, to whose pooled re-granting infrastructure OSF has been one of the named historical supporters alongside European bilateral aid agencies and other large US foundations — but ADRF is a small grant programme, where OSF is one of the field's largest single sources of capital. Following the 2023 announcement of an approximately 40% staff reduction and a deliberate shift toward a smaller number of "Open Society Programs" focused on democratic practice, rights and dignity, equity in governance, and future worlds, OSF has continued to be a globally dominant funder of digital-rights and AI-accountability work, with its 2024 spending concentrated in the United States ($242 million), Latin America and the Caribbean ($117 million), Europe and Central Asia ($84 million), Africa ($70 million), Asia Pacific ($26 million), and the Middle East and North Africa ($19 million).
AI-good footprint
OSF's most legible co-anchor role in the corpus's AI-good field is its co-launch of the Public Interest AI initiative. On 1 November 2023, OSF announced that it had joined the Ford Foundation, the MacArthur Foundation, the Mozilla Foundation, the David and Lucile Packard Foundation, Democracy Fund, Heising-Simons Foundation, Kapor Foundation, Omidyar Network, and the Wallace Global Fund in a ten-foundation collaborative committing more than $200 million toward "ensuring that AI advances the public interest." The announcement was timed to coincide with Vice President Kamala Harris's keynote at the global AI Safety Summit week and was organised around five focus areas Harris had identified: protecting democracy and rights, public-interest innovation, workers' rights and labour standards, transparency and accountability of AI models and companies, and the development of international AI rules and norms. Laleh Ispahani, then Executive Director of Open Society–U.S., framed OSF's entry into the coalition as turning on the field-level distribution of AI's benefits — that "AI tools could benefit people all over the world—but who they serve will depend on how they are developed, used, and overseen."
The Public Interest AI collaborative is the most visible single AI-grantmaking commitment but not the most distinctive of OSF's AI-good entries. Three other strands are characteristic. First, the AI in Journalism Futures programme — launched in February 2024 as OSF's inaugural scenario-planning workshop — convenes journalists, civil-society researchers, and academics to imagine how AI capabilities might restructure the global information ecosystem over a five-to-fifteen-year horizon, with the explicit aim of feeding that scenario work back into OSF's own field-shaping decisions in journalism and platform accountability. Second, OSF is one of the founding funders of the Spyware Accountability Initiative (SAI), a New Venture Fund-hosted pooled fund launched in 2023 alongside Apple, Luminate, the Limelight Foundation, Okta for Good, and Craig Newmark Philanthropies; SAI has since announced over $4 million in initial grants to civil-society research, litigation, and investigative work on mercenary spyware, and has grown into one of the field's largest pooled vehicles for advocacy on state-sponsored intrusion of activists, journalists, and human-rights defenders — work that increasingly overlaps with AI-driven surveillance tooling. Third, OSF is a founding philanthropic partner of the European AI & Society Fund (launched in 2020 as the European AI Fund), the Brussels-based Network of European Foundations-hosted re-granting fund that has awarded €13.6 million across 27 European countries to civil-society organisations working on AI policy, advocacy, and accountability; the European AI & Society Fund is a primary mechanism by which OSF's AI-good capital reaches Continental European civil society at scale.
Direct grantees in the corpus
OSF's AI-good footprint also runs through direct project grants to organisations the corpus already tracks. Big Brother Watch's funding-transparency page names OSF as a past grant-maker that provided project-specific funding for Poverty Panopticon, the July 2021 investigative report documenting UK councils' use of mass profiling, predictive risk scoring, and algorithmic systems to "citizen-score" welfare and social-care recipients — one of the corpus's earliest UK case studies in automated decision-making harm and a key public-record artefact for the wider UK Welfare Data Watch field. Through the Open Society Justice Initiative, OSF's standing public-interest litigation arm, the network has been an institutional supporter of strategic-litigation work on the rights implications of biometric and digital-ID systems: OSJI supported the Nubian Rights Forum's constitutional challenge to Kenya's National Integrated Identity Management System (Huduma Namba) and authored the public legal analysis of the resulting High Court ruling — the analysis cited in Katiba Institute's sourcing and the case in which the current Katiba Institute Executive Director Nora Mbagathi had previously worked as a strategic-litigation lawyer at OSJI before her October 2024 appointment.
Relationship to the broader AI-good movement
Within the funder slice of this corpus OSF fills the global multi-region funder slot — the first entry with a substantial pooled operating presence across Africa, Asia, Europe, Latin America, the Middle East and North Africa, and the United States, distinct from the country- or region-anchored portfolios of the corpus's existing US, UK, and pan-African entries. It is also the first funder entry whose AI-good footprint runs not only through direct grantmaking but through pooled-fund co-launches (the Public Interest AI initiative, the Spyware Accountability Initiative, the European AI & Society Fund), an in-house public-interest litigation arm (OSJI), and standing thematic-programme infrastructure on journalism, democratic practice, and rights and dignity. The wider AI-good landscape that the corpus documents — algorithmic-accountability research, biometric and digital-ID litigation, platform and content-moderation governance, anti-spyware advocacy, and the Continental European civil-society organising on the EU AI Act — sits inside a philanthropic field that OSF has co-anchored alongside the Ford Foundation for more than a decade, and OSF's distinctive contribution within that field is the combination of scale, regional reach, and its willingness to operate its own programmes (OSJI, AI in Journalism Futures) alongside its grantmaking.
