Billionaire Stanley Druckenmiller Dumped 94% of His Amazon Fund Stake and Plunged into a Hot Chip Stock for the First Time in 8 Years.

While earnings season is a milestone for many investors each quarter, don’t overlook the value of filing Form 13F with regulators. 13F data that keeps Wall Street’s smartest money managers bought and sold in the most recent quarter. This includes Duquesne Family Office millionaire investor, Stanley Druckenmiller.

Duquesne’s 13F shows that Druckenmiller sent shares to the commerce goliath Amazon (NASDAQ: AMZN) at the cutting edge, while simultaneously piling on one of Wall Street’s red-hot chip stocks, Intel (NASDAQ: INTC).

Amazon almost got the heave-ho

In each of the last half of 2025, Duquesne’s billionaire manager was a buyer of Amazon stock. He opened a position by buying 437,070 shares during the quarter ended September, and picked up another 300,870 shares in the fourth quarter. When 2025 ended, Amazon was Duquesne’s seventh largest by market value.

But that is ancient history. Druckenmiller sold 692,140 shares of Amazon during the quarter ended in March, effectively trimming his holdings by 94%.

Druckenmiller is an active investor, which means something as simple as a stop loss may have started in the first quarter. Iran’s war-driven war on Wall Street dragged Amazon shares from $225 to $240 during the last six months of 2025 to nearly $200 in the first quarter. The average time held in the top 10 in Duquesne’s investment portfolio is just five months.

However, short-term price movements may not tell the whole story.

In a May 2024 CNBC interview, Druckenmiller pointed out that artificial intelligence (AI) “might be huge now, but under a long term.” The world’s No. 1 cloud infrastructure services platform, Amazon Web Services, has seen its high-margin sales accelerate following the integration of AI solutions. However, Amazon shares aren’t cheap by traditional fundamental metrics, such as the price-to-earnings ratio. Valuation may have been the impetus that prompted Druckenmiller to show most of his Amazon stake in the door.

Stanley Druckenmiller piled on Intel before its historic launch

On the other end of the spectrum, a Duquesne billionaire investor amassed 411,400 shares of central processing unit (CPU) kingpin Intel ahead of a jaw-dropping second quarter. If Druckenmiller still owns these shares, they are up more than 100%! This is the first time he has held Intel shares since the first quarter of 2018.

Another innovation of Intel is related to the evolution of AI. However Nvidia (NASDAQ: NVDA) continues to blow away analysts’ expectations, given the unwavering demand for its high-end graphics processing units, the demand for CPUs in AI data centers is rising rapidly.

Additionally, Intel has some very powerful investors in its corner. Nvidia officially invested $5 billion in Intel in December — and it’s not a bad idea to have Nvidia as an investor and operating partner. The Trump administration also invested $8.9 billion in Intel by August 2025, which is more than quintuples.

Finally, the Duquesne billionaire is often attracted to companies with company names involved in game-changing (AI) whose shares have risen to multi-year highs. Intel fits the bill as a replacement candidate, thanks to AI, but it’s far from a significant deal following its high move.
