“Individuals” covers both small-dollar (under $200) and large donors.
Who are the biggest donors?
Every donor ranked by how much they gave, from the candidate’s own FEC filings — individuals, PACs, and party committees all in one list. Expand a candidate to see theirs, then tap any name to learn more about the donor.
Why are so many gifts exactly $10,000? That’s the legal maximum a PAC can give one candidate for the whole cycle — $5,000 for the primary plus $5,000 for the general — so many PACs give the max. Individuals can give up to $3,500 per election.

Showing the 50 biggest of 6665 donors. The other 6615 gave $10.7M combined.
Plus $1.2M from small donors giving under $200 each — those aren’t itemized by name.
These figures come from the candidate’s own itemized FEC reports (2026 cycle, through the coverage date above), with amendments applied and refunds netted. Joint fundraising transfers are left out of the ranking: they’re pass-throughs, and the individual donations behind them are listed above. Bank interest, vendor refunds, and other non-donation receipts are excluded. Donor names are as reported — the same person can appear twice if their name was recorded differently. Independent spending on ads is never included here — see the Outside spending column.
Common questions

The funding chain behind Honest Choice Maine, the pop-up super PAC that spent $287K in Maine's Senate race ($195K against Democrat Troy Jackson, $38K for Republican Susan Collins), is now documented one level up. Its Pre-General report (filed Oct 22) itemizes a single receipt: $500,000 on Oct 5 from Conservative Americans PAC (FEC #C00855924), a super PAC run by treasurer Charles Gantt (Bulldog Compliance, Beverly, MA). Conservative Americans PAC's own filings show it is funded almost entirely by the American Prosperity Alliance — a 501(c)(4) 'dark money' nonprofit whose donors are not disclosed — including a $27.8 million contribution on Dec 24, 2025 and more than $30 million this cycle in total; the Senate Leadership Fund also gave it $895,000. The same Conservative Americans PAC bankrolled a network of sham 'progressive' PACs (Lead Left, Real Change PAC, California Blue, Progressive Champions) that meddled in Democratic primaries. Honest Choice Maine leaves PoliVion's donor watchlist; the trail ends at the Alliance's hidden donors.
Democratic-aligned 'Stronger Nation' spends $550,003 across eight Senate races in the final stretch
Stronger Nation (C00898999), a Los Angeles-based hybrid PAC registered in March 2025, reported $550,003 in independent expenditures across eight Senate races, all disseminated October 22 via Democratic digital firm Rising Tide Interactive: supporting James Talarico and opposing Ken Paxton in Texas ($216,868), and backing Sherrod Brown in Ohio, Abdul El-Sayed in Michigan, Annie Andrews in South Carolina, Josh Turek in Iowa, Adam Hamilton in Kansas, Dan Osborn in Nebraska, and Troy Jackson in Maine. The PAC had reported no contributions at all through October 14, so the money behind the ads is undisclosed until its post-general report, due December 3; its only disclosed funder ever is the Chicago 501(c)(4) Rapid Resist Action ($130,000 in 2025).
Established GOP super PAC Red Senate adds $150K across four Senate races
Red Senate (C00747121), a Republican super PAC active since 2020, added about $150,000 in new independent expenditures: in TX-Sen ($172,890 for Ken Paxton / $53,388 against James Talarico), MI-Sen ($94,409 for Mike Rogers / $80,188 against Abdul El-Sayed), ME-Sen ($13,163 for Susan Collins / $17,325 against Troy Jackson), plus $5,000 against Annie Andrews (SC-Sen). Recent buys ran through Disney Advertising and If It Is LLC (filed Oct 20). Its donors are disclosed (led by At-Bay Insurance and GOP law firms Holtzman Vogel and Jassy Vick Carolan).
New Maine super PAC 'Honest Choice Maine' spends $232K in the Senate race: $195K against Troy Jackson
The super PAC (registered Sep 28) spent $194,582 opposing Troy Jackson (D) and $37,511 supporting Susan Collins (R) in Maine's Senate race, both disseminated Oct 14, via Relay Media Group. It uses the same GOP compliance shop (Crosby Ottenhoff) and Bryant Bank account infrastructure that investigators tied to a documented sham-PAC network; no principal or funder is identified yet. Donors are undisclosed until the pre-general filing around Oct 22. UPDATE Oct 28: its Pre-General report's Schedule A (filed Oct 22) itemizes the money — the committee's only receipt was a single $500,000 contribution on Oct 5 from Conservative Americans PAC (C00855924), a Republican super PAC funded almost entirely by the dark-money 501(c)(4) American Prosperity Alliance. Honest Choice Maine is cleared from PoliVion's donor watch; the chain now dead-ends at APA's undisclosed donors.
