Amazon Was Q2's Most Widely Bought Stock. Here's What the 13Fs Actually Show

When you rank the Q2 2026 13F filings by how many funds bought a stock rather than how many dollars went in, one name sits at the top: Amazon. According to 13F.finance's consensus tally, 41 tracked hedge funds added AMZN during the quarter, ahead of Alphabet (38) and Meta (33). SpaceX drew far more net dollars, but that number is skewed by a handful of giant pre-IPO marks. Amazon's buying was different: it was broad.

Breadth matters. A single $2 billion purchase can be one manager's high-conviction bet. Forty-plus funds leaning the same direction in the same quarter says something about how the professional crowd is reading the market.

Who Bought, and How Big

The list of Q2 buyers cuts across investing styles that rarely agree on much:

• Peter Thiel (Thiel Macro) opened a brand-new position of about 495,000 shares, worth roughly $118 million. It's now reported as the fund's single largest holding.
• Stanley Druckenmiller (Duquesne Family Office) went from about 46,000 shares to roughly 542,000 — a more-than-tenfold increase.
• Viking Global more than tripled its stake, from 1.2 million to 3.7 million shares.
• David Tepper (Appaloosa) raised his position about 33% to roughly $1.19 billion.
• Coatue grew its holding to about $2.82 billion.
• Seth Klarman (Baupost) also added, which stands out given how rarely Baupost buys mega-cap tech.
• Renaissance Technologies added about 2.29 million shares, worth around $546 million.
• Citadel Advisors reported the largest AMZN position of any Q2 filer at about $2.59 billion.

You can see how these portfolios overlap — and where they don't — on the InvestorLens overlap tool. Compare Duquesne against Appaloosa, for example, and Amazon is one of the few names both managers raised hard.

Why a Macro Trader, a Value Investor, and a Quant Agree

The interesting thing isn't that hedge funds own Amazon. Almost everyone owns Amazon. It's that managers with very different playbooks moved in the same direction at the same time.

The likeliest explanation is valuation plus acceleration. Amazon's trailing P/E had compressed to around 21, and by enterprise value to operating cash flow, the stock traded near 17 — well below its 10-year average of about 26. For a value investor like Klarman, that's a margin of safety in a business that rarely offers one. For growth-oriented funds like Coatue and Viking, the pull was AWS, which reported 37% revenue growth to $42.2 billion — its fastest pace in 18 quarters — as AI workloads moved onto its infrastructure.

Druckenmiller and Tepper tend to buy when sentiment and fundamentals point in opposite directions. In Q2, the market was still focused on inflation pressure in retail while the higher-margin parts of the business — cloud, advertising, custom silicon — kept accelerating. When very different buyers all show up at once, that's usually the kind of gap they're betting on.

Renaissance's addition is a separate signal. RenTech's 13F is driven by systematic models, not stories. Its buying suggests the quantitative factors — momentum, earnings revisions, relative value — were lining up too.

What the Filings Can't Tell You

Before treating Amazon as a "smart money consensus" trade, keep the usual 13F caveats in mind:

The data is stale. Q2 filings show positions as of June 30. By the time they were published in mid-August, funds had already had six more weeks to trade, and we're now nearly through Q3. Any of these managers could have trimmed since.

Longs only. A 13F shows long equity positions and certain options, but not shorts or most derivatives. A fund might own AMZN as one half of a pair trade against another retailer or cloud provider. The filing won't show the hedge.

Size vs. conviction. Citadel's $2.59 billion position is enormous in dollars but a small slice of a multi-strategy book. Thiel's $118 million is smaller in dollars but his largest holding. Weight inside the portfolio tells you more than dollar size — which is why each investor's page on InvestorLens shows position weights, not just market values.

Consensus cuts both ways. When 41 funds pile into the same mega-cap, the stock becomes more crowded. Crowded trades can unwind fast when a shock forces funds to cut risk at the same time — something we saw with AI names in July.

How to Use This Signal

The Amazon story is a good example of why breadth-based 13F signals are worth watching alongside dollar-based ones:

1. Check who's buying, not just how many. A consensus built from value, macro, growth, and quant managers is sturdier than one driven by a single style.

2. Look at the change, not the level. Duquesne's tenfold increase says more than Citadel's absolute size. The InvestorLens flow page highlights the biggest quarter-over-quarter position changes across tracked funds.

3. Cross-check with the macro picture. If the same managers are bullish on growth and rates, a mega-cap tech bet fits. If they're positioned defensively elsewhere, the Amazon buy may be a relative-value call rather than a bet on the market rising. The Macro Consensus dashboard shows how top investors are leaning.

Q3 13Fs arrive in mid-November. The key question is whether Amazon's buyer list keeps growing, or whether the quarter's most popular trade quietly starts shrinking.
