What Historic Haymarket Milwaukee Inc does
Mission
Historic haymarket milwaukee hhm exists to invest in, receive, hold, use, and dispose of all property, real or personal, as may be necessary or desireable for the purpose of developing and constructing a permanent museum building.

Program
On its FY2025 return the organization reported a significant change in how it conducts a program.
In May of 2025, HHM entered into a cooperation and transfer agreement with Wisconsin Museum of Nature and Culture, Inc. ("WMNC"). . After the execution of the cooperation and transfer agreement, HHM's operations are limited to the raising of additional funds, collection of pledges, and transfer of funds collected to WMNC, which owns the museum property and will operate the museum upon completion of the museum building. HHM's primary sources of revenue are derived from contributions, pledges and government grants.
Its own explanation, from Schedule O of that return (Part III, line 3).

The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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 2024 to 2025, from $103M to $35M (−66%).
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: 2022 1% · 2023 7% · 2024 14% · 2025 84%. Grants only. Government contracts and fees sit inside program revenue.
100% of Historic Haymarket Milwaukee Inc’s revenue is contributions — more reliant on donations than three-quarters of its peers (58% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 4 reported years ran a deficit.

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
2021 → 2023: the base broadened from 3 funders to 25 funders, grant income rose $355k → $5.3M.
9 of 55 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 11% 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: $5.8M from 5 payers (the payer shares this organization's board, largest Greater Milwaukee Foundation Inc). These are real filings, and they are not money Historic Haymarket Milwaukee Inc raised.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.9M arriving through sponsors registered in 6 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.
