TSMC pledged an additional $100B for its Arizona manufacturing complex, bringing total US investment to $265B. Chairman CC Wei cited surging AI chip demand for the expansion targeting 2nm and below nodes plus advanced packaging.
Key facts
- TSMC pledges additional $100B for Arizona expansion.
- Total US investment reaches $265B.
- Net income jumped 77% to $22B in Q2 2026.
- Targets 2nm and below nodes plus advanced packaging.
- Original 2025 commitment was $165B; first fab started volume output in early 2026.
TSMC chairman CC Wei said the firm planned to proceed "as fast as possible" with the new Arizona investment but declined to provide a timeline, noting that progress would "depend on the market situation and our customers' demand." According to SCMP
The US$100 billion is on top of the US$165 billion the company pledged for its Arizona complex in March 2025. At the time, TSMC boosted its original commitment of US$65 billion to US$165 billion, pledging to build three more fabrication plants, alongside two advanced packaging facilities and a research and development centre in Phoenix.

The additional investment was for "2-nanometre and below technologies, as well as advanced packaging fabs to support the strong multi-year demand from our leading US customers," Wei said at the firm's earnings conference on Thursday, after reporting record-high profits for the second quarter. Riding on the AI boom, the Taiwanese chipmaker's net income jumped 77 per cent to NT$706.6 billion (US$22 billion) in the second quarter.
Why this matters more than the press release suggests
The $265B total commitment represents a bet that US-based leading-edge manufacturing can compete with TSMC's Taiwan stronghold, even as geopolitical risk around the Taiwan Strait persists. The move also pressures Intel, which is investing $100B+ in its own US fabs and recently won Google's EMIB-T business for 9th-gen TPUs [as previously reported]. TSMC's Arizona ramp is now the largest single foreign direct investment in US history, but the company has a history of delays — its first Arizona fab, originally slated for 2024 production, began volume output only in early 2026.
What to watch
Watch for the timeline of the new fabs — Wei declined to commit to a date, and any slippage past 2028 would give Intel and Samsung more room to capture AI chip foundry customers. Also track whether TSMC's Arizona advanced packaging capacity can match its CoWoS output in Taiwan, as Nvidia and AMD increasingly demand US-based packaging for security-sensitive AI chips.
