The xETFs AI Bottlenecks ETF (NYSE:NECK) is an actively managed fund targeting companies linked to supply constraints across the artificial-intelligence ecosystem. Its focus includes memory, optics and photonics, networking, power and infrastructure, semiconductors and compute. Unlike broad AI ETFs, NECK emphasizes the physical and technological infrastructure required to scale AI and can adjust its holdings as bottlenecks shift. Companies are assessed using supply-and-demand imbalances, the durability and economic importance of constraints, pricing power, competitive positioning and valuation. xETFs CEO Johnny Wu said AI development can advance only as quickly as its scarcest inputs allow. Exchange Traded Concepts, LLC is the investment adviser, while WallStreetX ETFs, Inc. dba xETFs is the sub-adviser.
