01What it does

What The Salk Institute for Biological Studies does

Mission

Unlocking the secrets of life itself is the driving force behind the salk institute. Our team of world-class, award-winning scientists pushes boundaries of knowledge in areas such as neuroscience, cancer research, aging, immunobiology, plant biology, computational biology, and more. Founded by jonas salk, developer of the first safe and effective polio vaccine, the institute is an independent, nonprofit research organization and architectural landmark: small by choice, intimate by nature, and fearless in the face of any challenge.

As stated on its FY2025 Form 990.

Program

  1. The Salk Institute for Biological Studies is a world-renowed, independent research institute dedicated to advancing our understanding of life sciences and improving human health. Its programs bring together leading scientists across disciplines to explore fundamental questions in biology, from the molecular mechanisms of disease to the complexities of the brain and the impact of climate change on living systems. Through collaborative, curiosity-driven research and innovative technology, salk's programs aim to translate scientific discoveries into real-world solutions that benefit society. Below are highlighted scientific achievements during july 2024 through june 2025. Study reveals key gene protecting plants from harmful metals in soil - the excessive use of manure and sewage sludge can increase heavy metal concentrations in agricultural land where vital crops are grown. One of these heavy metals is zinc, a micronutrient necessary for plant and animal health. In excess, however, zinc can be extremely damaging to sensitive plant species. Salk researchers identified a gene, called trichome birefringence or tbr, that helps plants manage excess zinc by trapping it in their root cell…

The organization over time

Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

How it's funded, over time

Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.

03Who funds it

Who funds it, year by year

2017 → 2023: the base broadened from 53 funders to 77 funders, grant income rose $19M → $26M.

34 of 212 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 38% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

From the IRS filings of The Salk Institute for Biological Studies’s funders (the co-funder graph). Top 30 of 212 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

How concentrated its funding is

The Salk Institute for Biological Studies has a broad base — no single funder exceeds 11% of grant income, and it takes 11 funders to reach half.

the vertical line marks half of all grant income — 11 funders to its left

73% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund The Salk Institute for Biological Studies.

How long its funders stay

51% of The Salk Institute for Biological Studies's funders are still giving 3 years after their first grant; 67% give in more than one year at all.

first grant+1y+2y+3y+4y+5y+6y

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.

Funder states come from each funder’s own filing. $88M arriving through sponsors registered in 18 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2025 (financials across 2017–2025), and the filings of 212 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
