AI bottleneck moats

Query: AI bottleneck stocks with deep moats · data as of 2026-10-12

Built an "AI Bottleneck" screen of 43 US-listed deep-moat supply-chain chokepoints (compute/GPUs, foundry & CoWoS, HBM, semicap, EDA/IP, networking/optics, power/grid, generation, cooling, data centers, cloud), each filtered on business_model_score >= 7 or quality fundamentals (ROE>15%, GM>40%, positive FCF) and tagged with its constraint segment; sorted by moat score then market cap, with gross/net margin, ROE, revenue growth, 1M/6M/1Y returns, % from 150D SMA, P/E, forward P/E and momentum potential. Added a second table of 8 AI supply-chain ETFs (returns, expense ratio, top holdings) and a narrative mapping why each supply-chain layer is a bottleneck. Row-level commentary added for all names, framed around current market dynamics (platform owners vs. second-derivative hardware).
