Coinbase Global, 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 1,160 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

• Coinbase has two classes of common stock. Class A common stock (ticker COIN, Nasdaq) is the ONLY listed class, one vote per share, 222,803,032 shares outstanding as of 23 Jul 2026 (10-Q cover page). Class B common stock is unlisted, 20 votes per share, 41,033,891 shares outstanding as of 23 Jul 2026, held almost entirely by founder Brian Armstrong and, to a lesser extent, co-founder Frederick Ernest Ehrsam III and their affiliated trusts; it is convertible at any time at the holder's option into Class A on a one-for-one basis and converts automatically on most transfers (FY2025 10-K).
• company.shares_outstanding is set to Class A common stock outstanding (222,803,032) alone, because that is the instrument 13F filers report against (CUSIP 19260Q107) and the instrument this register's institutional rows are denominated in. market_cap_usd, by contrast, uses TOTAL shares across both classes (222,803,032 Class A + 41,033,891 Class B = 263,836,923) times the 19 Aug 2026 Nasdaq close of $160.20, because that reflects total equity value; this is a deliberate, stated departure from using shares_outstanding for market cap. Every pct_of_company and pct_of_target figure in this file states its own pct_denominator explicitly.
• Control: per the FY2025 10-K, 'Mr. Armstrong and the independent trustee of trusts established by Mr. Armstrong, collectively, are currently able to exercise voting rights with respect to a majority of the voting power of our outstanding capital stock.' Per the 2026 proxy's beneficial ownership table, Armstrong personally controls 49.6% of total voting power and the separate Armstrong trusts administered by independent trustee Jeffrey Billings control a further 18.9%, a combined 68.5% concentrated in Armstrong's founder control despite his Class A (listed) stake being only 3.67% of that class. Co-founder Frederick Ernest Ehrsam III separately controls 10.6% of total voting power via his own Class B holding.
• Coinbase holds crypto assets on its own balance sheet (Q2 2026 10-Q: 'Crypto assets held for investment' $1,468,395 thousand, 'Crypto assets held for operations' $86,469 thousand, 'Crypto assets held as collateral' $1,645,051 thousand, 'Crypto assets borrowed' $229,076 thousand, all as of 30 Jun 2026). These were identified and are deliberately EXCLUDED from holdings: crypto assets are not equity stakes in companies, the same exclusion this project applies to treasury and money-market holdings.
• Coinbase also carries a 'Strategic investments' balance sheet line of $840,287 thousand as of 30 Jun 2026 ($622,985 thousand at 31 Dec 2025). The FY2025 10-K describes this as investments in 'primarily privately held companies in the form of equity securities without readily determinable fair values in which we do not have a controlling interest or significant influence' where Coinbase 'holds less than 20% ownership' and does not exercise significant influence, almost entirely carried under the ASC 321 cost/measurement-alternative method. No individual investee is named or sized anywhere in the 10-K or 10-Q; this is a single combined balance covering an unknown number of private companies. Per the project's rule against assigning a combined balance to any one investee, NO holdings row was created for this balance; it is recorded here and in unknowns instead.
• EDGAR full text search confirms Coinbase Global, Inc. (CIK 0001679788) has never filed a Schedule 13G or 13D as a REPORTING OWNER of any other public company (search for 'Coinbase Global, Inc.' across SC 13G/SC 13D/SC 13G-A/SC 13D-A forms, and a browse-edgar company search for a Coinbase-named ownership filer, both returned zero results as of 20 Aug 2026). The only SC 13G/13G-A filings found under Coinbase's own CIK are filings AGAINST Coinbase as the subject company (i.e. other institutions reporting their ownership of COIN), not filings BY Coinbase.
• Self-gate computed on this final file exactly as the chart computes it (raw shares summed, aggregate container reduced to its residual against its two named members Armstrong and Ehrsam, everything else at full value): 13 register rows, 83,798,863 shares, 37.61% of the 222,803,032-share Class A denominator. This sits within the project's expected 25 to 45 percent band for a concentrated top-13 register.
• T. Rowe Price was checked on both registrants per the project's standing instruction: T. Rowe Price Associates, Inc. (CIK 0000080255) holds 514,073 shares of Coinbase per its Q2 2026 13F-HR (values reported IN THOUSANDS on this filer, as flagged elsewhere in this project: the raw filing shows $75,153 which is $75,153,000, implied price approximately $146.19/sh, consistent with everyone else); T. Rowe Price Investment Management, Inc. (CIK 0001897612) holds ZERO Coinbase shares in its own Q2 2026 13F-HR. Neither entity is large enough (0.23% of Class A) to warrant a register row alongside the top holders included above; recorded here as the check performed.
