Druckenmiller Dumped Alphabet — And Bought 11 Chip Stocks Instead

Stanley Druckenmiller has spent four decades building a reputation as the investor who refuses to fall in love with a position. His Q1 2026 13F filing for Duquesne Family Office, filed May 15 for the quarter ended March 31, is a textbook example of why: 31 brand-new positions, 23 full exits, and a portfolio that looks meaningfully different from the one he reported three months earlier.

The headline move is the exit from Alphabet. Druckenmiller sold his entire GOOGL stake, along with full exits from Goldman Sachs, ON Semiconductor, Wolfspeed, and Philip Morris. In their place, he opened new positions in a cluster of semiconductor and AI-infrastructure names: Arm Holdings, Broadcom, Micron, Intel, Coherent, Celestica, Cloudflare, Jabil, Seagate, SanDisk, and Lumentum. That's eleven new hardware-adjacent names added in a single quarter — a rotation, not a trim.

Out With the Mega-Cap, In With the Picks-and-Shovels

The Alphabet exit is the part of this filing getting the most attention, and it's worth sitting with. Druckenmiller isn't calling AI a bad trade — quite the opposite. He's betting that the next leg of returns sits one layer down from the platform giants, in the companies that supply the physical infrastructure those giants depend on: chips, memory, optical components, and contract manufacturing.

Broadcom is the clearest expression of that thesis. It was reportedly his largest dollar purchase of the quarter, landing as a new position alongside Arm. Add in Micron and Intel for memory and foundry exposure, Coherent and Lumentum for optical networking, and Celestica and Jabil for the assembly side of the AI supply chain, and you get a fairly complete picks-and-shovels basket — built from scratch in three months, funded in part by selling the platform name everyone else is still holding.

You can see the full new-positions list, including share counts and position sizing, on the Stanley Druckenmiller profile page. It's a useful one to bookmark — Duquesne's 54% trailing-twelve-month turnover means this portfolio rarely looks the same two quarters in a row.

The Other Conviction Bet: Natera

While the AI-hardware basket dominates the new-position list by count, it's not actually Duquesne's biggest position. That distinction belongs to Natera, the genetic testing company, which Druckenmiller increased again in Q1 to roughly 18% of the portfolio — by far his largest single holding and more than double the weight of his second-largest position. He's now added to Natera in consecutive quarters, the kind of repeated buying that, per Duquesne's own portfolio-persistence metrics, signals a high-conviction, long-duration thesis rather than a trade.

That's an unusual pairing: a famously macro-driven, sector-rotating investor running an 18%-weighted single-stock bet on a mid-cap diagnostics company alongside a rapid-fire basket of semiconductor names. It's a reminder that "macro investor" doesn't mean "doesn't do stock-picking" — it means the stock-picking sits on top of a view about where capital needs to flow next.

A Quiet Argentina Trade

Buried below the headline moves is a smaller but telling pair of additions: YPF, Argentina's state-controlled energy company, and Vista Energy, a separate Argentine shale producer. Druckenmiller more than quadrupled his YPF stake in the quarter (+433% in shares) and opened a new position in Vista. Combined with a continued stake in BBB Foods, a Mexican discount retailer, it adds up to a real allocation to Latin American growth — a theme that gets far less coverage than AI infrastructure but has shown up in more than one top filer's book this cycle.

What Got Cut

The exit list is as informative as the buy list. Beyond Alphabet, Goldman Sachs, and Philip Morris, Druckenmiller also closed out Chipotle, DoorDash, DocuSign, Entegris, Zillow, and Delta and American Airlines — fully closing the airline trade that several other macro funds have also been winding down this year. He didn't just trim these; he zeroed them out, which per Duquesne's own filing pattern usually means the original thesis either played out or didn't, and the capital was needed elsewhere.

He also meaningfully reduced — without fully exiting — Amazon (-71% in shares), Coupang (-61%), Teva (-60%), and Woodward (-64%), alongside trims to Taiwan Semiconductor and Insmed despite both remaining top-five holdings. Even his "keepers" got lighter.

Reading This Filing the Right Way

A few caveats matter here. First, this filing reflects positioning as of March 31 — filed 45 days later, in mid-May. Markets have moved since then, and Druckenmiller is exactly the kind of investor who might have already unwound or expanded on any of these positions by the time you're reading this. Second, a $3.4 billion family office sizing an 18% position in a single stock is taking a risk most individual portfolios shouldn't mirror at that weight.

What the filing is genuinely useful for is the read on where smart money sees the AI trade heading next. If a macro investor with this track record is selling the platform layer to buy the supply chain underneath it, that's a thesis worth understanding — even if your conclusion after researching it is different from his.
