AIPAC's money works to elect and defeat candidates through two channels, and different donors dominate each. Its super PAC, United Democracy Project, has taken in $217.8 million since 2022, including $51.5 million transferred from AIPAC's own treasury (its single largest funding source), and spends independently, without contribution limits. Its top private contributors (individuals and entities) are national names: Jan Koum ($7.0M), Jonathon Jacobson ($5.6M), Paul Singer ($5.5M), Bernard Marcus ($4.0M), Haim Saban ($4.0M), the Kraft Group ($3.0M), and Marc Rowan ($2.5M). The FEC bulk files examined (2022-2026 cycles) show no itemized contributions to UDP from Miriam Adelson.
Separately, thousands of donors have routed $85.9 million to hundreds of congressional candidates through AIPAC's PAC as earmarked ("bundled") contributions capped at $3,300 per candidate per election, a channel dominated by prolific check-writers rather than billionaires. The investigation ranks the top 50 donors in each channel, with location, profession, totals, and candidate counts, built from FEC bulk filings.
Neither list covers donations to AIPAC's lobbying arm, which are not publicly disclosed.
Key takeaways
United Democracy Project (UDP), AIPAC's super PAC, has raised $217.8 million since 2022. Its single largest funder is AIPAC itself, which transferred $51.5 million from its own treasury.
UDP's top private contributors are Jan Koum ($7.0M), Jonathon Jacobson ($5.6M), Paul Singer ($5.5M), Bernard Marcus ($4.0M), Haim Saban ($4.0M), the Kraft Group ($3.0M), and Marc Rowan ($2.5M).
Separately, 14,721 donors have routed $85.9 million to 413 congressional candidates through AIPAC's PAC as earmarked ("bundled") contributions, capped at $3,300 per candidate per election. That channel is dominated by prolific check-writers rather than billionaires.
The top 50 donors account for about 43% of UDP's private money but only about 10% of bundled money, reflecting how differently the two channels concentrate.
The largest private contributors to United Democracy Project, AIPAC's super PAC, are Jan Koum ($7.0 million), Jonathon Jacobson ($5.6 million), Paul Singer ($5.5 million), Bernard Marcus ($4.0 million), Haim Saban ($4.0 million), the Kraft Group ($3.0 million), and Marc Rowan ($2.5 million), according to FEC filings covering the 2022–2026 election cycles. The single largest source of UDP's money, however, is AIPAC itself, which transferred $51.5 million from its own treasury.
Does Miriam Adelson donate to AIPAC's super PAC?
Not according to FEC records: the bulk filings examined (2022–2026 cycles) show no itemized contributions from Miriam Adelson to United Democracy Project, even though she is among the largest pro-Israel political donors in the United States. Her disclosed election giving runs through her own committees instead, most notably roughly $100 million to Preserve America PAC, her pro-Trump super PAC, in the 2024 cycle. United Democracy Project also operates in a different lane, spending heavily in Democratic primaries. Whether she donates to AIPAC's lobbying arm directly cannot be determined, because those donations are not publicly disclosed.
What is the difference between AIPAC's PAC and United Democracy Project?
AIPAC's PAC collects earmarked ("bundled") contributions from individual donors and passes them to specific candidates, with each donor capped at $3,300 per candidate per election. United Democracy Project is AIPAC's super PAC: it accepts unlimited contributions and spends the money independently on advertising for or against candidates, rather than giving to campaigns directly. Different donors dominate each channel: billionaires fund the super PAC, while prolific check-writers dominate the bundled channel.
How much money has AIPAC given to its own super PAC?
AIPAC has transferred $51.5 million from its own treasury to United Democracy Project since 2022, making the organization itself the super PAC's single largest funding source, larger than any individual donor.
