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.
Government-grant reliance: 2017 3% · 2018 4% · 2019 5% · 2020 6% · 2021 28% · 2022 8% · 2023 19% · 2024 1%. Grants only. Government contracts and fees sit inside program revenue.
1% of Astrophysical Research Consortium’s revenue is contributions — more earned-revenue than three-quarters of its peers (68% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base held at 1 funder, grant income fell $5.0M → $1.8M.
From the IRS filings of Astrophysical Research Consortium’s funders (the co-funder graph). 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
Astrophysical Research Consortium leans on a few funders — its largest provides 91% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2017 100% · 2019 65% · 2020 100% · 2021 84% · 2022 100% · 2023 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.
Where its funders are
Astrophysical Research Consortium draws 100% of its grant income from funders outside Washington, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. 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.
Funders to approach
Grantmakers that don’t fund you yet, surfaced two ways: they back organizations that share your funders, or their grantees resemble your mission. The ones both signals agree on come first. Your 2 funders put you under-funded among the 400 organizations that share them.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2024 (financials across 2017–2024), and the filings of 2funders 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.
