Dark Money Spending
Election spending by organizations that do not disclose their donors. Dark money flows through 501(c)(4) social welfare organizations, 501(c)(6) trade associations, and similar entities that are not required to reveal their funders. Figures below are never combined with disclosed-donor totals.
IRS 990 Schedule I Grant Chain
Grants between nonprofits reported on IRS Form 990 Schedule I. These inter-organizational transfers are a key pathway in dark money flows — a nonprofit may receive a grant from one entity and then spend that money on election ads.

IRS 990 data lags a year or more behind filing. Grants shown are for the stated tax year and do not establish current-cycle funding.
Methodology Disclosure
Dark money figures are derived from FEC Form 5 (independent expenditures by non-committee organizations) and Form 9 (electioneering communications). These filings capture spending on ads and election communications but do not reveal the identity of the organization's donors. QPQ totals may differ from benchmarks like the Brennan Center's estimates because QPQ includes all Form 5 filers, while some benchmarks count only a subset of non-disclosing nonprofits. Grant chain data is from IRS Form 990 Schedule I and may not include all years or all grantee organizations.
