Featured legendary investors
Drawn from public 13F filings and reporting, these profiles focus on each legend’s AI positioning and reasoning — not their entire portfolio.
Warren Buffett
CautiousQ1 2026 brought the “great pivot”: Berkshire exited Amazon entirely and boosted Alphabet by 225%, while leaving Apple untouched — shifting its AI exposure from e-commerce/cloud toward search + full-stack AI.
Cathie Wood
BullishOne of the most aggressive AI bulls. Bets on AI infrastructure and next-gen compute — CoreWeave, Cerebras — and on nuclear (X-Energy) as AI’s energy base layer.
Stanley Druckenmiller
CautiousA stunning Q1 reversal: exited Alphabet entirely and rotated into SanDisk, Seagate, Micron, Broadcom and Intel — betting on AI’s memory/storage bottleneck, with tech exposure doubling from 9.4% to 18.4%.
Bill Ackman
BullishHolds only a handful of high-conviction names. Gains AI exposure through quality compounders like Alphabet rather than speculation.
Duan Yongping
CautiousA value investor anchored in Apple and Berkshire who leaned hard into the AI chain in 2026 — adding 91% to Nvidia (now #3), opening Tesla and adding PDD in Q1 while exiting Alibaba. Especially relevant for Chinese readers.
David Tepper
BullishIn Q1 2026 he nearly doubled Amazon into his #1 position (AI angle = accelerating AWS), while trimming Nvidia and AMD and leaning into Micron — “betting on AI monetization and the memory cycle, not pure compute.”
Philippe Laffont
CautiousQ1 2026: $29.1B across 62 names, with the top five now TSMC, GE Vernova, Lam Research, Applied Materials and Broadcom — full-stack AI infrastructure (foundry + equipment + power) — while adding 18% to Microsoft.
Michael Burry
BearishThe “Big Short” investor and the AI trade’s starkest bear: after winding down Scion in November 2025, he disclosed in May 2026 that ~80% of his personal book sits in Nvidia and Palantir put options (~$1.1B notional).
