Current case
- Strongest support
Broadcom Targets $58B in FY26 AI Revenue as ASIC Adoption Accelerates
As the leading pure-play foundry, TSMC is a primary beneficiary of increased demand for custom ASICs, regardless of the designer. Hyperscalers securing multi-year custom silicon capacity directly translates to higher wafer orders and advanced packaging demand for TSMC.
· Moves foundry utilization rates, advanced process technology demand, long term revenue growth
- Open question
TSMC maintains 72.5% fabrication share with $265B Arizona capex pipeline
Direct investment and market share confirmation. High capex could strain short-term free cash flow but secures long-term revenue and strategic importance.
· Moves long term growth rate, capital intensity, market share stability
