Ark’s Cathie Wood and Duquesne’s Stanley Druckenmiller both still own Amazon and Alphabet in latest 13F

Two of Wall Street’s best-known managers, Cathie Wood and Stanley Druckenmiller, appear aligned on one practical point in their most recent regulatory filings. Both ARK Investment Management and Duquesne Family Office disclosed holdings in Amazon and Alphabet in their quarterly 13F reports for the second quarter, according to a market report published by Yahoo Finance.

The 13F form is a mandatory filing with the U.S. Securities and Exchange Commission for certain large investment managers, reporting equity positions by issuer at a quarterly cadence. While 13F filings do not provide trading intent or full details on strategy, they offer a window into what large funds hold at quarter-end.

In the Yahoo Finance report, the managers are described as agreeing on ownership of Amazon shares, traded in the U.S. as AMZN, and Alphabet shares, traded as GOOGL. The article frames the overlap as notable because Wood and Druckenmiller have long been associated with different portfolio philosophies and approaches to risk, even as both have frequently focused on large-cap platform companies.

The same report places the disclosures in the context of the managers’ latest filing period, indicating that the overlap is based on second-quarter holdings rather than a longer-term estimate. That timing matters for investors because 13F positions can change quickly as funds rebalance, hedge, or react to performance over the quarter.

Amazon’s business spans online retail, subscriptions and digital services, advertising, and Amazon Web Services (AWS), its cloud computing unit that provides storage, data processing, and other infrastructure services to businesses. Amazon also publishes regular company and newsroom updates through AboutAmazon, which explains how AWS and other segments fit into its overall platform strategy.

For Alphabet, the core business drivers typically include advertising tied to search and YouTube, along with a growing set of technology bets. In market terms, Alphabet and Amazon are often treated as “platform” companies, where a combination of advertising, cloud or infrastructure services, and consumer ecosystems can reinforce demand.

Even so, the Yahoo Finance report as summarized here does not provide position sizes, cost bases, or whether the holdings were increased, reduced, or newly initiated during the quarter. It also does not indicate whether either manager held other related positions at the same time, such as exchange-traded funds, derivatives, or non-equity exposures that a 13F would not fully capture.

For readers trying to interpret what the overlap might mean, the safest takeaway is that both managers were willing, at quarter-end, to keep exposure to two of the market’s most liquid growth and infrastructure names. What remains unclear from the reported filing headlines is whether the managers’ theses for Amazon and Alphabet were unchanged, or whether they adjusted for sector trends, earnings expectations, or valuation swings in the second quarter.

The next watch items are straightforward. 13F updates again in subsequent quarters will show whether either manager adds to or trims AMZN or GOOGL, and whether the overlap persists. Meanwhile, investors will typically look to each company’s earnings releases and forward guidance to understand how fundamentals align with what managers are holding at the filing dates.
