ArXiv Secures Multiyear Funding to Establish Independence as a Nonprofit

By Kat Boboris | September 23rd, 2026

arXiv has officially announced the receipt of significant multimillion-dollar contributions from three prominent philanthropic entities. These investments are designed to facilitate arXiv's transition from its current state to an independent nonprofit organization.

The total investment amounts to \text{Total Funding} = \17.2 \text{ million}$, distributed over a period of three to five years. This capital will be utilized to bolster technical infrastructure, maintain daily operations, and enhance the global services provided to the scientific community.

The Strategic Vision for Independence

For roughly 35 years, arXiv has served as a cornerstone for the dissemination of scientific research. It currently supports millions of annual users across a diverse array of disciplines:

• Physics
• Mathematics
• Computer Science
• Quantitative Biology
• Quantitative Finance
• Statistics
• Electrical Engineering and Systems Science
• Economics

Roadmap to Autonomy

Funding Breakdown and Donor Perspectives

The financial support comes from three primary sources, each aligning with arXiv's mission of open access.

Leadership Insights

"I am grateful for the commitments from Simons Foundation International, XTX Markets, and Siegel Family Endowment, which put arXiv on solid footing as we move into this next chapter. Their generous support provides a strong foundation and momentum for arXiv to continue to grow and serve the research community for the long term." — Penelope Lewis, CEO of arXiv

"For 35 years, arXiv has made math and science more open, transparent, accessible and collaborative. By growing into an independent nonprofit, arXiv will be positioned to evolve and modernize its systems to better serve the scientific community and to secure its future." — David Spergel, President of Simons Foundation International

"Now, with rapid advances in AI driving changes across academia, it is even more valuable to have robust, open-source infrastructure for science. XTX Markets is delighted to continue our support for arXiv in this important endeavor." — Simon Coyle, Head of Philanthropy at XTX Markets

"Open access to knowledge is a cornerstone of a healthy research ecosystem... We’re looking forward to supporting arXiv in its next chapter as essential infrastructure, enabling communities to share ideas, build on one another’s work, and sustain a living body of knowledge." — Joshua Elder, SVP Head of Grantmaking at Siegel Family Endowment

Core Objectives and Implementation

The new funding is earmarked for three primary pillars of development. arXiv has outlined these as a set of critical milestones:

• General Operations: Maintaining and refining existing services for the global research community.
• Technical Evolution: Developing the platform to handle AI-generated content and other modern scholarly communication hurdles.
• Institutional Strengthening: Investing in the governance and operational frameworks required for a standalone nonprofit.

A Sustainable Financial Model

While these major grants provide a massive boost, arXiv relies on a diversified funding strategy to ensure long-term viability. This model can be conceptualized as follows:

def sustainable_funding_model():
    sources = {
        "Major Philanthropic Grants": "Foundational Support",
        "Membership Program": "Community Contribution",
        "Sponsors": "Corporate/Institutional Support",
        "Affiliates": "Partner Support",
        "Individual Donors": "Grassroots Support"
    }
    return sum(sources.values())

Recent Milestones

This announcement follows a series of significant events for the organization in 2026:

1. July 9th: arXiv surpassed the milestone of hosting over 3 million articles.
2. July 28th: The community honored the memory of Ralph Wijers.
3. July 30th: The organization welcomed its first-ever CEO and Board of Directors.
