The analysis suggests that while NVIDIA, AMD, and Broadcom are performing exceptionally well in the AI chip sector, TSMC is ultimately the biggest winner. The reason is that all AI chip designers, including hyperscale data centers like Amazon and Alphabet that develop their own chips, rely on TSMC for wafer fabrication and packaging. TSMC is the world's largest contract chip manufacturer, accounting for 73% of third-party manufacturing spending in Q1 2026, and plans to invest $60 billion to $64 billion in capital expenditures this year to maintain its technological leadership and mass production capabilities.
