Who Owns Walmart (WMT)? Institutional Ownership Map

Who owns the most Walmart?

The largest disclosed Walmart holders are the index giants. This is the single most important fact about WMT ownership and the one most "who owns Walmart" answers get wrong by leading with a hedge fund: the biggest holders are the funds that have to own Walmart because it is a large weight in the S&P 500 and other broad 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 Walmart 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 WMT's holder list as two layers.

The passive core is the top of the table: Vanguard, BlackRock, State Street, and Geode. These managers hold Walmart 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" 1.0%, that is mostly new money flowing into total-market and S&P 500 funds, not a Vanguard analyst turning bullish on retail. The same goes for Geode, which runs Fidelity's index sleeves, and for State Street's index franchise.

The active money is everyone making a position-sizing decision. That is where the signal lives, and it is mostly further down the list. On the buy side last quarter, Goldman Sachs added roughly 13% to its disclosed WMT long and Royal Bank of Canada added about 7%. On the sell side, the clearest active de-risking came from traditional stock-pickers: Franklin Resources cut its position about 25%, Fidelity (FMR) cut about 20%, UBS Group trimmed about 15%, and Ameriprise Financial trimmed about 10%. 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.

One number deserves a caveat. The single largest percentage "add" in the data is Barclays at about +135%, which looks dramatic, but a triple-digit jump from a bank's broker-dealer book usually reflects market-making inventory and client flow rather than a conviction bet, so we do not headline it as active buying. The honest active signal here is the spread between the broker-dealer adds and the active mutual-fund trims, not one outsized percentage.

Walmart positions are also sometimes expressed through options, and 13F reports put and call positions as flagged rows valued against the underlying. A naive aggregator that sums every WMT 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 WMT 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 WMT ownership from raw EDGAR right now, you will see multiple Vanguard entities reporting Walmart: Vanguard Group plus newer entities (Vanguard Capital Management LLC and Vanguard Portfolio Management LLC) that began filing separately after an internal reorganization. Sum all of them and you double-count billions of dollars of the same shares. 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 inflate Vanguard's true position. (Background: 13F amendments and restatements.)

What 13F does and does not tell you about WMT

Four limits to keep in mind before treating any "who owns Walmart" 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. WMT can move meaningfully 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 WMT" 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. Walmart's own officers and directors, including the Walton family's reporting persons, report their trades on Form 4 within two business days, a different and faster feed than 13F. See insider activity for WMT and the filing-type comparison.

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

How to track Walmart 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:

For an AI agent, the same data is exposed through MCP tools so the assistant can answer "which funds added Walmart last quarter" directly, with each figure carrying its source filing and quarter. Start with the MCP quickstart, the 13F data layer, or the live Walmart 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 Walmart's largest institutional shareholder?

Among institutional 13F filers, Vanguard Group reports the largest Walmart position, around $49 billion at its latest filing, followed by BlackRock at around $44 billion. Both are index-fund managers holding Walmart in line with its weight in major indexes, not active stock-pickers. (Note that this 13F view covers institutional managers, not the Walton family's direct and trust holdings, which are reported separately.)

How many institutions own Walmart?

1,059 institutional managers disclose a Walmart long position in their most recent 13F filings in our dataset, totaling roughly $369 billion in reported value. 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 funds are buying or selling Walmart?

On the buy side last quarter, Goldman Sachs added about 13% to its disclosed WMT position and JPMorgan Chase added about 6%. On the sell side, active managers led the trims: Franklin Resources cut about 25%, Fidelity (FMR) about 20%, and UBS Group about 15%. Screen the full list, weighted by manager quality, on the investors leaderboard rather than reading one fund in isolation.

Is Walmart mostly owned by index funds?

At the top of the cap table, yes. The largest disclosed institutional holders are 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 Walmart'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.
