Nvidia still holds approximately 70% of the AI chip market share, but that share is projected to erode as Google, Amazon, Meta, Microsoft, and OpenAI invest billions in purpose-built chips designed for their specific workloads. ASIC-based AI server shipments are projected to reach 27.8% of the market in 2026, the highest share since 2023, which also forecasts that custom ASIC shipments will grow 44.6% year-over-year in 2026, nearly triple the 16.1% growth rate projected for merchant GPUs.
This is being enabled almost entirely by TSMC, which fabricates chips for all five hyperscalers and for Broadcom, the dominant custom AI chip architect. Broadcom alone carries a $73 billion AI backlog and is targeting $100 billion in annual AI chip revenue by 2027.
