TSMC is accelerating its $165 billion Arizona Gigafab expansion, confirming the 2026 groundbreaking of dedicated domestic advanced packaging plants (AP1 and AP2) to secure a full U.S. supply chain for AI-grade silicon.
- This strategic move eliminates the need to ship U.S.-made chips back to Taiwan for CoWoS packaging.
- Construction on Fab 2 for 3nm technology is also accelerating, targeting mass production by the second half of 2027.
- Despite the operational strength, TSM stock declined 1.43% to $337.42, tracking a broader tech sell-off.
