Cornell University Library (CUL), the Simons Foundation, and a global collective of institutional members support arXiv financially. The financial model for 2013-2017 entails three sources of revenues:

• CUL provides a cash subsidy of $75,000 per year in support of arXiv's operational costs and an in-kind contribution of all indirect costs, which currently represents 37% of total operating expenses.
• The Simons Foundation contributes $100,000 per year in recognition of CUL's stewardship of arXiv. In addition, every year, the Foundation matches $300,000 of the funds generated through arXiv's membership fees.
• Each member institution pledges a five-year funding commitment to support arXiv. Based on institutional usage ranking, the annual fees are set in four tiers from $1,500-$3,000. Cornell's goal is to raise at least $300,000 per year through membership fees generated by approximately 208 institutions. Discounts for members paying through consortial agreements will be provided. 

Allen Institute for Artificial Intelligence provided a generous grant in 2017 to support the development of tools for automated quality control and improved search and retrieval experience.

We gratefully acknowledge the support of the following institutions for the arXiv membership model and their intentions for a five-year pledge, 2013-2017.  According to the arXiv's Principles , membership in arXiv and representation on the MAB is reserved for libraries, research institutions, laboratories, and foundations that contribute to the financial support of the service. Please see the arXiv Sustainability Initiative Website for information about the arXiv governance and business model.
