AI Chip Competition Heats Up: Marvell-Google Deal, Etched Threatens Nvidia's Moat

Marvell struck a custom chip deal with Google, directly challenging Broadcom's TPU dominance in AI inference. Goldman Sachs argues market overreacted, citing Broadcom's mass production moat and networking growth. Meanwhile, Michael Burry warns of Etched, a startup delivering specialized ASICs for transformers with 10x performance and 44-day turnaround, challenging Nvidia's moat beyond CUDA. These developments signal fragmentation in AI chip supply chain and potential threats to incumbents. Nvidia's response includes exploring a $20B investment in AI data supplier Mercor, expanding its vertical integration. Investors should monitor competitive dynamics and their impact on NVDA, AVGO, MRVL, and GOOGL.
