"In 2023, arXiv received a $5 million grant from the National Science Foundation (NSF Grant 2311521 | “Frameworks: arXiv as an accessible open access research platform”). Distributed over five years (performance conclusion: 2028) this grant’s goal is to create a more discoverable and accessible arXiv to advance scientific innovation."
That's $1 million/year.
Total revenue in 2023 was $2,690,592.
Edit: my mistake. I’ve always heard it referred to as a “state school” which is true given its land grant status and SUNY affiliation, but it is private.
Engineering, Arts and Science, Architecture, Hotel Administration
are private, while:
Industrial & Labor Relations, Agriculture and Life Sciences, Human Ecology
accept public funding. That info might be ~20 years out of date though.
"Cornell is a privately endowed research university and a partner of the State University of New York."
