Capital One Financial Corporation

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 2,040 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 Discover acquisition has closed and Discover is excluded from holdings. Per the 8-K filed 19 May 2025, effective 18 May 2025 (the Closing Date) Capital One completed its acquisition of Discover Financial Services pursuant to the Merger Agreement dated 19 February 2024: Merger Sub merged into Discover, then Discover merged into Capital One, with Capital One as the surviving entity. Discover is therefore a wholly owned part of Capital One, not a holding, and the brief excludes wholly owned operating subsidiaries. This is also why Capital One's share count is far larger than a pre-deal base: each Discover share converted into 1.0192 Capital One shares (per the 2026 proxy), and shares outstanding grew to 613,484,836 at 30 June 2026 (10-Q cover), 621,925,120 at 18 February 2026 (proxy denominator) and 625,102,271 at 31 December 2025 (10-K/10-Q balance sheet). Register percentages below do not sum past 100 percent of any of these counts.
• Capital One does not currently file Form 13F. Its complete EDGAR filing history under CIK 0000927628 (submissions JSON and the SEC 13F browse-edgar feed, both checked 17 August 2026) shows only five 13F-HR filings, the most recent for the quarter ended 31 March 2022 (filed 13 April 2022); none since. So the client-assets trap that removes JPMorgan's, Bank of America's, Goldman's, Wells Fargo's, Morgan Stanley's and Citigroup's own 13F from their holdings does not currently apply to Capital One: there is no current Capital One 13F to exclude, and none of the 13F rows in the register below are Capital One's filing, they are seven other managers' 13Fs reporting on Capital One stock.
• Brex is also a wholly owned subsidiary, excluded from holdings. Per the Q2 2026 10-Q, Capital One agreed on 22 January 2026 to acquire Brex, Inc. (business corporate-card and expense-management fintech); total consideration to Brex shareholders was approximately $4.5 billion ($2.6bn cash plus 10.6 million Capital One shares worth $1.9bn). The acquisition closed within the quarter: Brex's $1.1bn of outstanding debt was paid off immediately on completion, integration expenses of $96 million were incurred in Q2 2026, and Brex's results are now included within the Domestic Card segment (part of Credit Card). This is an acquisition, not a stake.
• Holdings is empty and that is the sourced finding, not a gap. Both the Q2 2026 10-Q (period ended 30 June 2026, filed 28 July 2026) and the FY2025 10-K (period ended 31 December 2025, filed 19 February 2026) were searched in full for 'equity method', 'equity securities', 'non-marketable', 'measurement alternative', 'affordable housing', 'investments in', 'strategic investment', 'ownership interest', 'minority stake', 'joint venture' and 'equity interest in'. No named investee company, public or private, with a sized equity stake was found in either filing.
• The one figure that exists is a combined balance covering many investees, so per the brief none of them is sized individually. The FY2025 10-K states the carrying value of investments included in other assets, excluding tax-advantaged investments, totaled $1.3 billion at 31 December 2025 ($1.2 billion at 31 December 2024), which primarily comprised equity investments measured using the alternative measurement method ($764 million at 31 December 2025, $757 million at 31 December 2024) and equity-method investments, described only as 'variable interests in companies that promote renewable energy sources and other equity method investments'. No investee is named and the equity-method-only portion is not separately stated, so this entire balance goes to notes and unknowns rather than into any holding row.
• Affordable housing and low-income/rural-community tax-credit vehicles were found and deliberately excluded, per the brief's guidance that these are structured tax-equity investments rather than strategic stakes in named operating companies. Capital One discloses unconsolidated 'Affordable housing entities' VIEs (private investment funds making equity investments in multifamily affordable housing, generating tax credits, accounted for by the proportional amortization method) with a carrying amount of assets and maximum exposure to loss of $6,947 million at 30 June 2026 ($6,485 million at 31 December 2025), plus 'Entities that provide capital to low-income and rural communities' at $40 million (30 June 2026) and $48 million (31 December 2025). None of this is recorded as a holding.
• No Visa legacy shareholding was found for Capital One, unlike JPMorgan's disclosed Visa Class B-3/C stake from the 2008 member-bank IPO. The Q2 2026 10-Q and FY2025 10-K mention Visa only in the context of interchange-fee litigation and network competition; no equity holding is disclosed.
• Vanguard and BlackRock register reconciliation, recorded rather than resolved. The 2026 proxy's 5 percent beneficial-ownership table, sourced to Schedule 13D/13G filings and computed against 625,102,271 shares outstanding at 31 December 2025, shows The Vanguard Group at 63,618,145 shares (10.2 percent, reflecting combined pre- and post-Discover-transaction ownership per the proxy's own footnote, based on a Schedule 13G/A for Capital One and an April 2025 13G/A for Discover) and BlackRock, Inc. at 44,226,407 shares (7.1 percent, based on a Schedule 13G/A reporting BlackRock's position as of 31 December 2023, over two years stale). The register above instead uses each manager's own most recent Form 13F-HR, which is more current: Vanguard's quarter ended 31 December 2025, BlackRock's quarter ended 30 June 2026.
• JPMorgan's row is JPMorgan Chase & Co. acting as an asset manager holding Capital One stock in its own Form 13F, unrelated to Capital One's holding of anything. As with the Morgan Stanley and FMR rows, this is very likely overwhelmingly client wealth-management and market-making inventory rather than a conviction stake in a competitor; labelled 'active' here for lack of a more precise category, following the same convention used in the JPMorgan and Broadcom research files for bank-manager rows.
• Capital One has a single class of common stock, one vote per share; no dual-class structure. Founder, Chairman and CEO Richard Fairbank's beneficial stake is small in voting terms (proxy marks it with an asterisk, meaning less than 1 percent), despite his tenure since 1994 and a reported approximately $40 million in 2025 performance-year compensation per the same proxy.
• Denominators used across this file: 613,484,836 shares outstanding at 30 June 2026 (10-Q cover page) for the current-quarter 13F register rows; 625,102,271 at 31 December 2025 (10-K/10-Q balance sheet) for the Vanguard 13F row, which is dated to that quarter; 621,925,120 at 18 February 2026 (the proxy's own beneficial-ownership-table denominator) for the two insider rows. Market capitalization of $139.47 billion as of 14 August 2026 (stockanalysis.com) implies a share price of about $227.34, consistent with 613,484,836 shares times that price.
