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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $6.3M to $8.2M (+30%).
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 3% · 2019 4% · 2020 6% · 2021 3% · 2022 2% · 2023 2% · 2024 1%. Grants only. Government contracts and fees sit inside program revenue.

the vertical line marks half of all grant income — 2 funders to its left
55% 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 BOSTON CELTICS SHAMROCK FOUNDATION INC.
Largest funder’s share by year: 2017 48% · 2018 29% · 2019 26% · 2020 36% · 2021 65% · 2022 29% · 2023 31% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $4.8M arriving through sponsors registered in 10 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. 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.
