How big is Stanley Druckenmiller's portfolio?

The latest 13F discloses $2.9B across 65 positions in Q1 2026. 13F filings cover US-listed long positions only; cash and short positions are not disclosed.

How up to date is this?

Funds file 13Fs up to 45 days after each quarter ends, so this portfolio reflects Q1 2026, the latest disclosed quarter. The filing date is shown with every table.

Where does the Duquesne Family Office LLC portfolio data come from?

Non-rejected, non-superseded SEC Form 13F filings for Duquesne Family Office LLC provide the Q1 2026 holdings, disclosed values, and filing date shown here. WhoBought prefers filings whose value units validate and labels a sparse filing when validation is unavailable. Industry labels come from the local company classification record.

How is performance calculated?

Performance uses daily closing prices for holdings with available market-price history. It covers the priced share of disclosed value (67%); holdings without sufficient price history are excluded from the calculation.

Who is Stanley Druckenmiller?

Stanley Druckenmiller is an American investor who founded Duquesne Capital in 1981 and later became the lead portfolio manager for George Soros's Quantum Fund.

How did Druckenmiller enter investing?

After studying English and economics at Bowdoin, he left an economics PhD program to become an oil analyst at Pittsburgh National Bank. He founded Duquesne a few years later.

What was Druckenmiller's role in Black Wednesday?

Druckenmiller and George Soros took a large short position against the British pound in 1992 after concluding that the Bank of England could not sustain its defense of the currency.

Does Stanley Druckenmiller still run a hedge fund for outside clients?

No. He returned outside investors' money and closed Duquesne Capital in 2010. This page instead follows the later Duquesne Family Office filing.

What was Duquesne Capital's historical record?

Wikipedia reports an average annual return of about 30 percent with no money-losing year during the fund's run. That historical figure is separate from the current family-office holdings shown here.

What is Druckenmiller's investment style?

He is a top-down investor who has combined long and short stock positions with leverage, futures, and currency trades. That makes a stock-only 13F an incomplete picture of his approach.

Is this Druckenmiller's personal portfolio or net worth?

No. It is the Duquesne Family Office 13F filing. It does not calculate his personal wealth or disclose every asset held by the family office.

Can a reader reproduce Druckenmiller's strategy from the 13F?

No. The filing can reveal selected long equity positions, but it leaves out the shorts, currencies, futures, leverage, and timing decisions central to his style.
