Mid-August 13-F filings showed Stanley Druckenmiller, David Tepper and Peter Thiel leaning into AI-exposed mega-cap technology stocks in the second quarter of 2026, collectively putting well over $1 billion into Amazon and Alphabet while Appaloosa's portfolio centered on Amazon, Micron, Taiwan Semiconductor, Meta and Alphabet. Duquesne Family Office opened a new Alphabet position of about 336,300 shares valued at roughly $120 million at the end of Q2, while Thiel Macro reported a new $118 million stake in Amazon that accounted for 28% of its roughly $419 million portfolio after reportedly remaining out of equities for several previous quarters. Appaloosa kept Amazon as its largest holding and reduced Micron shares by more than 41%, underscoring a selective tilt toward the biggest AI infrastructure beneficiaries rather than a narrow single-name bet. The disclosures are backward-looking snapshots as of June 30 and may not reflect current holdings, but they reinforce a shared preference for the cloud and data-center platforms underpinning AI demand. The case for Amazon was bolstered by AWS reporting 37% revenue growth in Q2 2026 and a backlog that rose to $496 billion, signaling accelerating demand for AI-related cloud services.
