Who Owns Coinbase (COIN)? Institutional Ownership Map

Who owns the most Coinbase?

The largest disclosed Coinbase holders are the index giants. This is the single most important fact about COIN ownership and the one most "who owns Coinbase" answers get wrong by leading with a hedge fund: the biggest holders are the funds that have to own Coinbase because it is now a meaningful weight in broad US equity and financials indexes.

Values are each filer's reported long position as of its most recent 13F; live figures and the full holder list are on the Coinbase ownership page. The "as of" column matters: 13F filings arrive asynchronously, so one quarter's largest filer may be a quarter ahead of another's.

The passive core vs the active money

Read COIN's holder list as two layers.

The passive core is the top of the table: Vanguard, BlackRock, State Street, and Geode. These managers hold Coinbase in proportion to its index weight. Their quarter-over-quarter moves track fund flows and index rebalancing far more than any view on the stock. When Vanguard "adds" 0.7%, that is mostly new money flowing into total-market and S&P 500 funds, not a Vanguard analyst turning bullish on crypto exchanges. Even the "new" Vanguard Portfolio Management position is an entity artifact rather than fresh conviction (more on that below).

The active money is everyone making a position-sizing decision. That is where the signal lives, and it is mostly further down the list. Last quarter the standout active long move was Patient Capital Management, the value shop run by Bill Miller's former Legg Mason team, which grew its Coinbase stake by about 141% to roughly $75M, a genuine conviction-driven add rather than an index print. Ruffer LLP, the London multi-asset manager, added close to 95% to bring its position near $251M. On the other side, ARK Investment Management, long one of the most vocal COIN bulls, trimmed its disclosed long by about 6.7%, and managers including NATIXIS and IEQ Capital cut harder (down roughly 45% and 32% respectively). None of those is a verdict on the stock by itself, but a screen of who is adding versus trimming, weighted by manager quality, is the actual use of this data. The smart-money leaderboard is the practical starting view.

A note on the eye-popping percentages near the top of the "biggest adds" list: figures like a +285% jump from Credit Agricole or +194% from a multi-strategy desk are usually small-base or facilitation positions (market-making, swap hedges) rather than a directional bet, so we do not headline them as conviction. The cleaner read is a meaningful add on a meaningful base, which is why Patient Capital and Ruffer are the names worth watching here.

One nuance specific to COIN: managers frequently express Coinbase views through options, and 13F reports put and call positions as flagged rows valued against the underlying. A naive aggregator that sums every COIN row into a "long book" turns a protective put into a bullish bet. Our data separates option legs from the long-equity book, so a manager's reported COIN long is the share position, not a blended notional. (More on that trap: 13F options, puts and calls explained.)

A data-quality footnote: the Vanguard reorg

If you pull COIN ownership from raw EDGAR right now, you will see multiple Vanguard entities reporting Coinbase: Vanguard Group plus newer entities (such as Vanguard Portfolio Management LLC) that began filing separately after an internal reorganization. Sum them naively and you double-count the same shares, inflating Vanguard's true position by well over a billion dollars. This is the kind of identifier and entity-resolution problem that makes institutional ownership data hard to keep clean, and it is exactly what a sourced, deduplicated layer is for. We model the reorg so the combined view does not overstate Vanguard's real stake. (Background: 13F amendments and restatements.)

What 13F does and does not tell you about COIN

Four limits to keep in mind before treating any "who owns Coinbase" number as complete:

• It lags up to 45 days. A 13F reports positions as of quarter-end and is due 45 days later, so the picture can be a full quarter stale by the time you read it. COIN can move 30% in that window.
• It is long-only. 13F covers long positions in 13(f) securities. Short positions, cash, and most derivatives net exposure do not appear. A fund that looks "long COIN" on a 13F may be hedged.
• It misses smaller and foreign holders. Only managers with $100M+ in 13(f) securities must file a Form 13F, so retail, smaller funds, and many non-US holders are invisible here.
• Insiders file separately. Coinbase's own officers and directors report their trades on Form 4 within two business days, a different and faster feed than 13F. See insider activity for COIN and the filing-type comparison.

The honest summary: 13F tells you which large institutions disclosed a Coinbase long position at the last quarter-end and how it changed, not who owns Coinbase in real time.

How to track Coinbase ownership as it updates

The durable workflow is to resolve the entity once, pull the holder list, and diff across quarters rather than reading a single filing. With the REST API:

curl -H "Authorization: Bearer YOUR_KEY" \
  "https://arkolith.com/api/v1/stocks/COIN"

For an AI agent, the same data is exposed through MCP tools so the assistant can answer "which funds added Coinbase last quarter" directly, with each figure carrying its source filing and quarter. Start with the MCP quickstart, the 13F data layer, or the live Coinbase ownership page. Every figure on those surfaces is sourced to its SEC EDGAR accession, which is the point: an ownership claim without a filing date and quarter-end is incomplete.

Frequently asked questions

Who is Coinbase's largest shareholder?

Among institutional 13F filers, Vanguard Group reports the largest Coinbase position, around $6.0 billion across its entities at its latest filing, followed by BlackRock at around $2.9 billion. Both are index-fund managers holding Coinbase in line with its weight in major indexes, not active stock-pickers.

How many institutions own Coinbase?

362 institutional managers disclose a Coinbase long position in their most recent 13F filings in our dataset, totaling roughly $16.9 billion. That count covers managers with at least $100M in 13(f) securities; it excludes retail holders, smaller funds, and many foreign holders that do not file 13F.

Which hedge funds and active managers own Coinbase?

Most active managers hold far smaller stakes than the index giants and frequently use options. Recent standout active moves include Patient Capital Management roughly doubling its position (up about 141%) and Ruffer LLP adding close to 95%, while ARK Investment Management trimmed its long. Screen the full list, weighted by manager quality, on the investors leaderboard rather than reading one fund in isolation.

Is Coinbase mostly owned by index funds?

At the top of the cap table, yes. The largest disclosed holders are all index or quasi-index managers (Vanguard, BlackRock, State Street, Geode), whose stakes track index weight and fund flows. The active, conviction-driven positions sit lower in the list and are where quarter-over-quarter changes carry the most signal.

Is 13F ownership data live?

No. A 13F is a quarterly snapshot filed up to 45 days after quarter-end, so Coinbase's disclosed ownership can be months old by the time it publishes. Use it for institutional positioning and quarter-over-quarter changes, never as a live book.
