xETFs is launching the xETFs AI Bottlenecks ETF

, an actively managed fund built around companies positioned at critical supply-chain constraints across the AI industry.

Rather than concentrating on the sector's most visible names, NECK seeks to invest in the physical and technological chokepoints where the xETFs team sees supply struggling to keep pace with demand.

What NECK Targets

NECK invests in companies across four core areas: Memory; Optics, Photonics & Networking; Power & Infrastructure; and Semiconductors & Compute. The fund also leaves room for exposure to bottlenecks that may emerge as the AI landscape evolves.

“As powerful as AI has become and as great as its promise still may be, the AI buildout can only move as fast as its scarcest inputs allow,” said Johnny Wu, Co-founder and CEO of xETFs. “When demand outpaces supply, the companies at the most critical points of constraint in the supply chain can see growing backlogs, increased pricing power, and consistent revenue as they look ahead. With NECK, we are looking beyond the most visible names in AI and targeting companies positioned at the physical and technological bottlenecks limiting the AI buildout.”

How Companies Are Selected

xETFs evaluates prospective holdings on supply and demand dynamics, durability and barriers to entry, economic materiality and pricing power, and valuation. The underlying thesis is that companies sitting at genuine constraint points, rather than simply riding the AI theme broadly, are better positioned to see backlogs grow and pricing hold.

Why Active Management

Wu pointed to how quickly the bottleneck landscape can shift as the reason for building NECK as an actively managed fund rather than a fixed index product. “This is a fast-moving space, and bottlenecks may emerge, and ease, over time,” he said. “That was why we felt it was essential to make NECK an actively managed ETF and why we are so excited to bring this new fund to market.”
