MAYO CLINIC
MAYO CLINIC (Minnesota) receives grants from 1722 organizations whose IRS filings report $1,189,817,667 to it, the largest being FIDELITY INVESTMENTS CHARITABLE GIFT FUND ($82,617,352). 1052 of them have funded it in more than one year. MAYO CLINIC administers funds for other donors, so those contributions arrive into funds it holds rather than supporting a program it runs itself.
Hosts funds for others
MAYO CLINIC administers funds on behalf of other donors. The grants recorded as coming in are contributions into those funds, so they count custody rather than support for a programMAYO CLINIC runs itself. This page therefore states the flows and does not draw the comparisons it would draw for an operating charity: concentration, funder retention, grant dependency and the peer field are all left out, because each of them would read a vehicle as if it were a program.

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.
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 4% · 2018 4% · 2019 4% · 2020 6% · 2021 4% · 2022 5% · 2023 5% · 2024 5%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 361 funders to 715 funders, grant income rose $55M → $172M.
166 of 1722 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 30% 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: $11.2B from one payer (the payer shares this organization's board, largest Mayo Clinic Group Return); $28k from one payer (the same organization on both sides, largest Mayo Clinic); $5k from one payer (an institutional transfer, not a grant programme, largest Nbi Inc). These are real filings, and they are not money MAYO CLINIC raised.
From the IRS filings of MAYO CLINIC’s funders (the co-funder graph). Top 30 of 1722 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.
Where its funders are
MAYO CLINIC draws 87% of its grant income from funders outside Minnesota, across 50 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $355M arriving through sponsors registered in 37 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.
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 1722 funders put you well-backed among the 400 organizations that share them.
