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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $4.0B to $5.9B (+48%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base narrowed from 7 funders to 1 funder, grant income fell $243k → $48k.
3 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 66% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $1.8B from one payer (the payer shares this organization's board, largest Foundation to Promote Open Society). These are real filings, and they are not money OPEN SOCIETY INSTITUTE raised.
From the IRS filings of OPEN SOCIETY INSTITUTE’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
OPEN SOCIETY INSTITUTE leans on a few funders — its largest provides 37% of grant income and the top three 66%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
93% 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 OPEN SOCIETY INSTITUTE.
Largest funder’s share by year: 2017 38% · 2018 45% · 2019 63% · 2020 66% · 2021 56% · 2022 82% · 2023 100% — growing more concentrated.
“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.
How long its funders stay
22% of OPEN SOCIETY INSTITUTE's funders are still giving 3 years after their first grant; 46% give in more than one year at all.
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.
Where its funders are
66% of OPEN SOCIETY INSTITUTE's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $321k that is directly attributable, 94% of it comes from funders outside New York, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $618k arriving through sponsors registered in 1 state 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. 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.
