Cathie Wood
ARK Invest
One 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.
Investment thesis
Wood views AI as a cross-industry “general-purpose technology” driving a productivity boom; she favors the earliest, highest-beta layers.
Q1 2026 13F: ~$12.9B across 181 positions, anchored by Tesla (8.2%) with AMD now #2 (4.3%); she added AMD, Tempus, Amazon, Alphabet and CoreWeave, opening 17 names and exiting 32.
Style note: high volatility and turnover with deep drawdowns — better as a clearly-sized high-risk satellite than a core holding.
