Citigroup Inc.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 2,418 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• The 13F exclusion, read this first. Citigroup Inc. itself files a Form 13F: the filing for the quarter ended 30 June 2026 (accession 0000831001-26-000040, filed 3 August 2026) contains 11,343 information table rows. This is client, custodial, brokerage and wealth-management inventory managed by Citi's asset management and private bank arms, not Citi's own strategic equity book, the same reasoning that excluded JPMorgan (34,064 positions), Bank of America (18,318), Goldman Sachs (14,070) and Wells Fargo (18,984). None of these 11,343 rows are converted into holdings here.
• Banamex, read this second. As of the Q2 2026 10-Q (period ended 30 June 2026, filed 6 August 2026), Grupo Financiero Banamex, S.A. de C.V. remains a CONSOLIDATED subsidiary of Citigroup, not a holding. Sequence established from the filings: the FY2025 10-K (filed 20 February 2026) describes 'completing the sale of a 25% equity stake in Banamex in 2025'. The Q2 2026 10-Q describes a further, separately announced 24% stake sale, of which 22.6% closed on 29 April 2026 to 'several prominent institutional investors and family offices' and the remaining 1.4% was expected to close in Q3 2026, subject to customary closing conditions (not yet closed as of the 10-Q's filing date). The 10-Q states the cumulative CTA-loss reclassification to date is 'from the 47.6% stake sales' (25% plus 22.6%), meaning Citi retained approximately 52.4% of Banamex's voting stock at 30 June 2026, still comfortably majority-owned. The 10-Q explicitly states: 'Citi will deconsolidate Banamex when it owns less than 50% of Banamex's voting stock and does not have substantive participating rights in Banamex.' A Banamex IPO is referenced only as 'the proposed Banamex initial public offering (IPO)', with timing and structure of any subsequent transaction still to be decided; no listing has occurred. Per the brief, a wholly or majority owned, consolidated operating subsidiary is excluded from holdings, so no Banamex row is recorded. If Citi's stake later falls below 50% and Banamex is deconsolidated, that stake would become a holding at that point, likely first at basis 'announced_transaction' / confidence 'contingent' until a filing confirms deconsolidation.
• No other named equity-method or non-marketable equity investee was found. The Q2 2026 10-Q and FY2025 10-K were searched for 'equity method', 'equity securities', 'non-marketable', 'measurement alternative', 'significant influence', 'joint venture', 'equity interest in', 'minority interest in' and 'strategic investment'. Every equity-securities disclosure found is a combined balance covering many unnamed investees: non-marketable equity securities carried at cost of $6.0 billion (30 Jun 2026) versus $5.1 billion (31 Dec 2025); non-marketable equity securities measured using the measurement alternative of $1,707 million (30 Jun 2026, FY2025 10-K comparative period figures shown as $1,707m / $1,574m); non-marketable equity securities carried at fair value of $446 million / $427 million; and marketable equity securities carried at fair value of $475 million / $151 million. None of these notes name a single counterparty, so per the brief none is distributed across individual holdings; the combined figures are recorded here, not as sized positions.
• Citi is not a legacy Visa member bank in the way JPMorgan, Bank of America and Morgan Stanley are. A full-text search of the Q2 2026 10-Q for 'Visa' returned only litigation references (Visa/Mastercard interchange settlement) and a glossary definition of 'closed loop' payments; no Visa Class B, B-3 or C common stock position was found anywhere in the filing.
• Citigroup has a single class of common stock (plus non-voting preferred series C-PN and C-PR), one vote per share. There is no dual-class structure and no founder or controlling shareholder. Insider ownership is immaterial: the proxy states that at 23 March 2026 no Director or Executive Officer individually held more than 1% of outstanding common stock, and all 30 Directors and Executive Officers as a group held approximately 0.11%.
• Register reconciliation on Vanguard and BlackRock. Citi's 2026 proxy 5% table gives BlackRock, Inc. 129,265,958 shares (6.9%), sourced to a Schedule 13G/A filed 24 April 2025, and The Vanguard Group, Inc. 166,504,200 shares (8.7%), sourced to a Schedule 13G/A filed 13 February 2024. Both are older and, for BlackRock, both lower than the register's 13F-based figures used here (BlackRock's own Q2 2026 13F-HR: 149,509,189 shares). Vanguard's own most recent 13F-HR under CIK 0000102909 is for the quarter ended 31 December 2025 (filed 29 January 2026, 163,239,926 shares); no Vanguard Group 13F-HR for the March or June 2026 quarters was found under that CIK, consistent with the pattern seen in prior research files where Vanguard's holdings for a given complex are reported by other, differently named Vanguard reporting-manager entities in some quarters. The register uses each manager's own most recent 13F-HR rather than the proxy's older 13G data.
• Register percentages use 1,677,436,783 common shares outstanding as of 30 June 2026, from the Q2 2026 10-Q cover page. Vanguard's row is dated to its own 31 December 2025 13F-HR (the most recent one on file for that CIK) but is divided by the same 30 June 2026 denominator for comparability with the other rows; this slightly understates Vanguard's percentage relative to using a 31 December 2025 share count.
• The market capitalisation of $233.72 billion is the figure published on stockanalysis.com as of 14 August 2026. Cross-check: 1,677,436,783 shares outstanding at a share price near $139 implies roughly $233bn.
• The Jane Fraser and aggregate insider rows overlap: the 'Total (30 Directors and Executive Officers as a group)' row of 1,864,086 shares (0.11%) contains Jane Fraser's 332,827 shares and must not be added to them.
