How much has AIPAC and its affiliated PACs donated to other congressional members since 2018?

1. A sharp shift since 2021 — AIPAC moves from behind‑the‑scenes to big public spending

AIPAC historically worked behind the scenes, relying on members’ contributions rather than directly funding candidates, but beginning in 2022 it began directly funding congressional campaigns and outside efforts; sources say AIPAC spent about $13 million in the 2022 midterms and then emerged as one of the largest outside spenders in 2024, with its combined program — AIPAC PAC plus affiliated super PACs like the United Democracy Project (UDP) — accounting for roughly $100 million in election‑related spending that cycle ^{[1] [3]}.

2. What the PAC numbers show: tens of millions to candidates

AIPAC’s bipartisan political action committee reported being the largest PAC contributor in the 2023–2024 cycle, giving more than $55.2 million to federal candidates, and AIPAC’s own site says it provided over $53 million in direct support to 361 candidates in 2024 — figures that align in showing AIPAC’s PAC funneled tens of millions directly into congressional campaigns during and after 2018 (p2_s1; ^[7] referencing PAC totals; p1_s7).

3. Super PAC and outside spending roughly doubles the picture

Counting super PAC activity and related outside spending changes the aggregate significantly: reporting and FEC filings cited by multiple outlets conclude AIPAC‑affiliated groups and pro‑Israel outside spenders poured roughly $100 million into the 2024 cycle — a sum that includes UDP and other outside spending beyond the AIPAC PAC’s direct donations ^{[1] [3]}.

4. Month‑by‑month spikes and noteworthy transfers

Investigative filings reviewed by outlets found concentrated bursts of giving — for example, AIPAC’s PAC delivered more than $3.7 million in one November filing and sent six‑figure or larger sums to dozens of lawmakers in compressed periods tied to legislative fights over aid to Israel ^{[4] [5]}. These monthly spikes reflect AIPAC’s strategy of timing contributions when congressional leverage is highest ^{[4] [5]}.

5. Broader pro‑Israel PAC landscape and contrasting totals

OpenSecrets and other aggregators separate “pro‑Israel” PACs overall from AIPAC specifically: one OpenSecrets industry table showed pro‑Israel PACs gave about $5.43 million to federal candidates in 2024, a different tally reflecting methodology and which committees are included ^[6]. That discrepancy highlights how totals vary depending on whether you count only AIPAC PAC, include UDP and other affiliated super PACs, or aggregate all organizations self‑identified as “pro‑Israel.” ^{[6] [2]}

6. Ongoing activity beyond 2024 — continued large donations in 2025

Post‑2024 filings show the AIPAC PAC and its affiliates continued large contributions: AIPAC’s PAC gave more than $12.7 million in PAC contributions in the first half of 2025 alone, and UDP and related groups reported mid‑year fundraising in 2025 ^{[7] [8]}. This indicates AIPAC’s electoral spending has not been confined to a single cycle ^{[7] [8]}.

7. Limits and caveats in available reporting

Direct, single‑number answers are elusive because different sources count different entities: AIPAC PAC’s direct candidate donations, UDP’s super PAC ad buys, other AIPAC‑aligned outside spending, and aggregate “pro‑Israel” PAC totals are reported separately and use different windows and FEC classifications ^{[1] [6] [2]}. The federal FEC database remains the primary raw source for receipts and disbursements; one can browse contributor‑level filings there to assemble a precise year‑by‑year congressional recipient list ^[9].

8. How to get a precise, itemized total since 2018

For an exact sum to individual members since 2018 you will need to (a) extract AIPAC PAC disbursements from FEC records, (b) add UDP and any named super PAC transfers tied to AIPAC (using FEC and mid‑year/annual reports), and (c) decide whether to include third‑party “pro‑Israel” donors tracked by OpenSecrets and trackers like Track AIPAC; the FEC receipts/search tool is the recommended starting point ^{[9] [6] [10]}.

Conclusion: available sources document that AIPAC’s PAC gave tens of millions to federal candidates (more than $53–$55 million in 2024 alone) and that AIPAC‑affiliated groups and outside spending pushed the total electoral footprint toward roughly $100 million in 2024; ongoing filings for 2025 show continued large giving, but assembling an exact, member‑by‑member total since 2018 requires compiling FEC itemized disbursements and deciding which affiliated committees to include ^{[2] [1] [3] [9]}.
