National Science Foundation

NSF is the federal government's main funder of basic science that doesn't have a company behind it yet -- research too early-stage for venture capital and too foundational for any one university to pay for alone.▸ Congress enacted $8.75 billion for NSF's FY2026 budget -- almost exactly what it got in FY2025 -- after the administration's own request had asked to cut that same year's funding to $3.903 billion, a reduction of more than half.

NSF exists because of one sentence: "To promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..." That's the purpose clause of the National Science Foundation Act of 1950 (Public Law 81-507) -- still the law that runs the place, compiled today at 42 U.S.C. § 1861 et seq.) Section 1861 sets NSF up as its own independent federal agency), run by a Director and a National Science Board -- not tucked inside a cabinet department.▸ Section 1862 spells out the job): fund basic research and science education across math, physical science, biology, social science, and engineering, and hand out fellowships to do it. NSF marked its 75th anniversary on May 10, 2025.

In FY2025, NSF evaluated 43,532 proposals through competitive merit review and funded 8,377 of them -- a 19% funding rate, down from 26% the year before.▸ That ran through 1,621 colleges, universities, and other institutions in 50 states, D.C., and 3 territories, scored by 30,858 outside scientists and engineers who volunteered for review duty and conducted 197,242 individual reviews. The average competitive award was worth $260,362.

Every proposal gets scored on two things: "Intellectual Merit" -- does it advance knowledge -- and "Broader Impacts" -- does it do anything for society beyond the lab.▸ NSF also runs the Graduate Research Fellowship Program -- 2,500 offers this year from nearly 14,000 applicants, part of a pipeline that's supported 71,500 students since 1952 -- a program NSF's own financial report credits with 274 Nobel laureates among its recipients.

NSF almost never runs its own labs.▸ About 25% of federal support for basic research at U.S. colleges and universities flows through NSF, which in an average year funds roughly 11,000 competitive awards across 1,900 institutions and supports about 350,000 researchers, entrepreneurs, students, and teachers. NSF is an independent agency, not part of a cabinet department -- run by a Director confirmed by the Senate, with a presidentially appointed National Science Board setting science policy and reporting to Congress and the President. Program officers pick the outside reviewers -- panel, ad hoc, or both -- and NSF aims to answer applicants within six months.

The clearest read on what NSF is worth showed up in its own paperwork this year.▸ The administration's original FY2026 request asked for $3.903 billion -- less than half of FY2025's $8.826 billion. Congress didn't go along: it enacted $8.75 billion instead, within 1% of the prior year. The FY2027 request repeats almost the identical ask -- $3.963 billion, a cut NSF's own budget table pegs at 55.1% against FY2025. Whatever the politics, the pattern says something: the people who actually write the check keep deciding NSF's baseline is worth protecting, even when the people proposing the budget don't. Without NSF, the 25% of federal university basic-research funding it supplies has no other single backer standing behind it at that scale.
