From the IRS filings of MIRRORBOX THEATRE’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
MIRRORBOX THEATRE leans on a few funders — its largest provides 43% of grant income and the top three 95%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
28% 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 MIRRORBOX THEATRE.
Largest funder’s share by year: 2020 75% · 2021 97% · 2022 59% · 2023 100% — growing more concentrated.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $48k arriving through sponsors registered in 3 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.
