OTF receives the majority of its funding from the U.S. government via the U.S. Agency for Global Media (USAGM). Funding is appropriated for OTF through the annual  Department of State, Foreign Operations, and Related Programs appropriations and provided to OTF via a grant agreement from USAGM.

For FY 2023, Congress allocated $90.5 million for programs to promote Internet freedom globally, representing a $13 million increase from FY 2022. Of the funds allocated for Internet freedom, $40 million was designated for OTF. Per the appropriations, all Congressional funding provided to OTF is used to support “programs to promote Internet freedom globally.” In addition to helping to further OTF’s mission, this funding increase is also further recognition of the increasing need for the tools and technologies OTF supports.

In addition to funding from USAGM, OTF also accepts funding from other mission-aligned donors for discrete Funds, Labs, or Fellowships. For example, OTF’s FOSS Sustainability Fund is supported in part by funding from Schmidt Futures’ Plaintext Group, Okta for Good, and the Github Foundation.
