Broadcom's CEO has projected $100 billion or more in annual custom AI chip revenue by 2027.1 The entire production pipeline runs through one place: Taiwan.
TSMC, the Hsinchu-based foundry that manufactures chips for Apple, Nvidia, and Broadcom alike, operates at advanced nodes no rival currently matches at scale. South Korea's Samsung and US-based Intel Foundry trail on both yield and capability for cutting-edge AI chip designs. Switching foundries takes years, not quarters.
Three converging threats now pressure that supply chain. Military conflict in the Taiwan Strait would halt TSMC production immediately — a disruption that would cascade through global AI infrastructure. Tightening US export controls on advanced semiconductor equipment could constrain TSMC's own tool supply. Chinese economic pressure or cyberattacks could create indirect production delays without military action.
A current risk assessment rates this scenario catastrophic in severity with medium likelihood.1 A prolonged disruption would stall deliveries across Broadcom's entire AI chip portfolio. No near-term alternative exists.
Broadcom's hyperscale customers — cloud providers across North America, Europe, and Asia building custom silicon for AI inference and training — have little recourse. These chips are engineered specifically around TSMC's process nodes. Redesigning for another foundry, if one existed at comparable capability, would take 18 to 24 months minimum.
The $100 billion revenue target sharpens the concentration risk. A multi-quarter TSMC disruption could erase a large portion of projected AI chip revenue. Neither Broadcom nor its customers have a short-term mitigation path.
Governments have responded with industrial policy. The US CHIPS Act funds domestic advanced node capacity. Japan attracted TSMC to build fabs in Kumamoto. The EU Chips Act targets expanded European production. None close the gap with Taiwan's current output on any near-term timeline.
TSMC's Arizona facilities run at lower volumes than Taiwan operations. The global AI industry's dependence on a strait separating Taiwan and China is a systemic risk embedded in every projected AI revenue figure — not a footnote.
For investors and enterprise customers pricing Broadcom's AI chip roadmap globally, the Taiwan variable remains the single largest unhedgeable risk in an otherwise strong demand story.
