The field of nuclear security is experiencing a major shake-up. Last summer, the MacArthur Foundation announced that it was withdrawing, which some observers called "a big blow' and others said came at "the worst possible time".

With some new organizations (like Longview) stepping in, however, the actual level of funding shortfall, if any, is unclear.

This question is designed to provide guidance to potential philanthropists looking to assess the overall funding levels of nuclear security 3 years into future.

How much philanthropic funding will go to nuclear issues in 2025?

This question will resolve based on data from the Peace and Security Funding Index, for the total amount of funding in 2025, filtered by Subject Area to "Nuclear Issues." Government funding will be excluded.
