What are the largest itemized PAC contributions to Indivisible Action in the 2023–2024 FEC filings and who listed them?

1. What the public summaries do confirm

Indivisible Action’s cycle-level totals are published: OpenSecrets reports $9,922,930 raised in 2023–2024 ^[1], and the FEC lists Indivisible Action as an active hybrid PAC with filings spanning the 2023–2024 period ^[2]; OpenSecrets also documents that there were thousands of large individual ($200+) donations reported to the PAC in 2024 (2,413 such contributions) rather than identifying large PAC-originated receipts ^[4].

2. What the question specifically asks — and why the supplied sources fall short

The user asked for the largest itemized PAC contributions to Indivisible Action and who listed them — a request that requires committee-level itemized receipts showing “contributor committee name / date / amount” entries. The FEC maintains an itemized committee contributions file and a receipts/browse-data interface that contain those line items ^[3], and Indivisible Action’s FEC committee page is the landing point for browsing receipts ^[2]. However, the supplied snippets and OpenSecrets pages in the search results do not include the actual itemized PAC-to-PAC contribution lines or a ranked list of “largest” PAC contributors to Indivisible Action, so those specifics cannot be asserted from the material provided ^{[2] [3] [4]}.

3. How to resolve the gap — where and how to get the definitive answers

To answer the question precisely, one must download or browse Indivisible Action’s itemized receipts on the FEC site (the committee page and the FEC’s itemized contributions file) and filter for contributions where the “contributor” is a PAC/super PAC/hybrid PAC, then sort by amount to surface the largest entries; the FEC’s “itemized committee contributions” file and the committee’s receipts tab are designed for that use ^{[2] [3]}. OpenSecrets aggregates donor data and is useful for summaries or for seeing large individual donors, but OpenSecrets’ donor pages in the snippets supplied show aggregate totals and counts rather than an explicit ranked list of PAC contributors to Indivisible Action ^[4].

4. Related context that matters to interpreting any large PAC donations

Indivisible Action is identified in outside summaries as part of the broader Indivisible ecosystem and is characterized as a Carey Committee/hybrid PAC in third‑party profiles ^[5], which affects the kinds of transfers and independent expenditures it can make and receive; additionally, public summaries show the PAC itself gave $18,500 to federal candidates in 2023–2024, a separate line of reporting that differs from incoming PAC receipts ^[6]. These structural details matter because “largest PAC contributions” could include transfers from affiliated entities, independent-expenditure funds, or corporate/super PAC checks — each of which is reported differently on FEC forms ^{[2] [3]}.

5. Balanced conclusion and next steps for verification

Given the available snippets, it is not possible to name the largest itemized PAC contributions to Indivisible Action in 2023–2024 or to identify which PACs listed them without consulting the FEC itemized receipts for committee C00678839; the authoritative path is to pull the FEC committee receipts or the FEC itemized contributions dataset and filter for contributors that are committees, then rank by amount ^{[2] [3]}. OpenSecrets and InfluenceWatch provide cycle totals and contextual reporting that help frame the PAC’s activity but do not substitute for the FEC’s line‑by‑line itemized receipts when the question is “which PACs, which amounts, who listed them” ^{[1] [5]}.
