Where this list came from

**Source**

[Exempt Organizations Business Master File Extract](https://www.irs.gov/charities-non-profits/exempt-organizations-business-master-file-extract-eo-bmf), Internal Revenue Service (IRS) (2026-09-07)

**License**

A work of the United States federal government. Not subject to domestic copyright (17 U.S.C. § 105).

**How we filtered it**

501(c)(3) organizations ranked by the total revenue on their most recent Form 990 (REVENUE_AMT), excluding entities filing a group return, whose revenue is not one organization's. The population is the true top 100 — we do not skip down the list to find rows with a website, which would select for fame rather than size. The BMF carries no web address, so the URL comes from Wikidata (see the wikidata source) joined on EIN, and roughly half the cohort has none and says so. Hospital systems and universities are not excluded even though they have cohorts of their own: the IRS's own NTEE codes put Northwestern under recreation and Dana-Farber under research, and a leaky filter that drops the wrong organizations is worse than an overlap the comparison can state.

**Instead of**

The Forbes and NPT 'largest charities' lists, both copyrighted compilations.

**Built**

2026-09-08

The filtering is ours and is disclosed as ours. The source published a list; the decision about which rows of it belong in a cohort was a judgment call, and it is written down so somebody can disagree with it.

How much of each site we read

The cap is 32 URLs and it is a ceiling, not a promise. A portal whose every link points at a different host yields one page; a university yields the full sample. The median here is **32**, the range 1–32 — published so that "we sampled 32 URLs per site" cannot become a claim the data does not support.

2 sites in this cohort served a certificate we could not verify. They were read anyway and scored normally — reporting no response for a site every browser loads would describe our TLS stack rather than the site — and each one carries the finding in its row.
