Executive summary

Reporting across investigative outlets identifies a cadre of billionaire and executive donors who have funneled large sums into AIPAC-affiliated political vehicles — most prominently the United Democracy Project (UDP), Democratic Majority for Israel (DMFI) and AIPAC PAC — but public accounts disagree on exact rankings and amounts and point readers to FEC records for definitive tallies [1] [2].

1. Who the reporters say are the biggest individual givers

Multiple investigative articles single out hedge‑fund and private‑equity figures as leading individual backers: Paul Singer is cited repeatedly as a top donor to AIPAC‑linked groups, with coverage putting his UDP contributions in the seven‑figure range (Truthout cites Singer at $1 million to UDP in the current cycle) while other outlets report different round numbers for Singer across cycles [3] [4]. Jonathan Gray, the Blackstone executive, is reported as having pledged roughly $1 million to AIPAC’s network according to Truthout’s reporting [3]. Marc Rowan of Apollo is named as a recurring UDP donor (Truthout reports $250,000 to UDP) [3]. Investigative sites also highlight a donor identified simply as “Marcus” who has given multi‑million dollar totals across cycles — LittleSis reports roughly $3 million in the current election cycle plus prior gifts [5].

2. High‑profile donors beyond Wall Street: Miriam Adelson and Jan Koum

Some outlets expand the list beyond financiers to include politically prominent givers: PressTV’s compilation lists Miriam Adelson as providing $5 million to an AIPAC‑affiliated Republican group (RJC) and names Jan Koum as a $2 million donor to the UDP in 2022, underscoring that wealthy tech and casino‑industry philanthropists figure in AIPAC’s donor base [4]. These claims are reported by the outlet but should be cross‑checked against FEC filings and other investigative databases for confirmation [2].

3. How these donations are routed and why totals vary across reports

AIPAC’s electoral spending is routed through multiple vehicles — AIPAC PAC, UDP, DMFI PAC and allied conduits — and journalists note that parse issues arise because some donations go to intermediaries or are earmarked by donors to specific PACs, producing inconsistent public totals across investigations [1] [5]. Sludge and related outlets analyzed FEC filings to compile donor lists but also caution that timing (donations in 2022 vs 2024 cycles), reporting categories, and conduit transfers can make headline figures appear to conflict [1].

4. Scale: the organization’s electoral muscle and its funding sources

Reporting establishes that AIPAC and its electoral affiliates have spent at least tens of millions and, by some estimates, more than $100 million in recent cycles, positioning the group among the top outside spenders; this scale makes even single seven‑figure gifts materially important to campaign operations and messaging efforts (LittleSis cites more than $100 million in spending and specific multi‑million expenditures in primaries) [5] [6].

5. Conflicting numbers, hidden agendas and what to verify next

Coverage comes from outlets with distinct perspectives and agendas — investigative left‑leaning outlets emphasize the role of corporate executives and critique AIPAC’s primary targets [1] [5], while international outlets like PressTV use harsher framing and list donors with different totals [4]. Given these editorial slants and reporting inconsistencies, the definitive source for donor names and amounts remains the Federal Election Commission’s receipts database; researchers should consult FEC records and cross‑reference databases like OpenSecrets and TrackAIPAC for reconciled totals [2] [7] [8].

6. Bottom line: who to list as the largest individual donors since 2022 — and why the list is provisional

Based on the assembled reporting, the most frequently named large individual donors since 2022 include Paul Singer, Jonathan Gray, Marc Rowan and a donor identified as “Marcus,” with additional high‑value names reported such as Miriam Adelson and Jan Koum; exact rankings and dollar amounts differ across sources because donations flow through multiple PACs, pledges differ from processed FEC receipts, and some outlets report pledged versus reported transfers [3] [5] [4] [1]. For a conclusive, audited list of top individual donors and precise totals, the FEC’s receipts search and reconciliations on OpenSecrets/TrackAIPAC should be consulted [2] [7] [8].
