The organization over time

Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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.

Who funds it, year by year

2017 → 2023: the base broadened from 3 funders to 10 funders, grant income rose $42k → $112k.

7 of 31 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 33% 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 ANTELOPE BUTTE FOUNDATION INC’s funders (the co-funder graph). Top 30 of 31 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

ANTELOPE BUTTE FOUNDATION INC has a broad base — no single funder exceeds 14% of grant income, and it takes 5 funders to reach half.

the vertical line marks half of all grant income — 5 funders to its left

38% 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 ANTELOPE BUTTE FOUNDATION INC.

Funder states come from each funder’s own filing. $627k arriving through sponsors registered in 7 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.
