We exist to move as much impact-adjusted money as possible to those working to reduce catastrophic and existential risks. In practice, we promote effective philanthropy that reduces the risk of a major global catastrophe through three main types of activities: advising, grantmaking, and events.
As stated on its FY2025 Form 990.

The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 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 $6.8M to $13M (+87%).
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.
99% of LONGVIEW PHILANTHROPY USA INC’s revenue is contributions — more reliant on donations than three-quarters of its peers (80% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 2 reported years ran a deficit.

Leadership and staff
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
Grant support over time, funder by funder — shade shows the grant size each year.
8 of 11 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 94% 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 LONGVIEW PHILANTHROPY USA INC’s funders (the co-funder graph). Top 10 of 11 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
LONGVIEW PHILANTHROPY USA INC leans on a few funders — its largest provides 39% of grant income and the top three 76%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
100% 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 LONGVIEW PHILANTHROPY USA INC.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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
94% of LONGVIEW PHILANTHROPY USA INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $1.0M that is directly attributable, 83% of it comes from Delaware funders.
Funder states come from each funder’s own filing. $17M 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.
