TSMC and GlobalFoundries Sign $2B US Packaging Deal
On October 8, 2026, GlobalFoundries announced a multi-year, $2 billion manufacturing agreement with TSMC to produce silicon interposers at its Malta, New York fab. This deal establishes GF as the first US-based source of silicon interposers supporting TSMC’s CoWoS ecosystem, with production ramping expected in 2028. The move addresses critical bottlenecks in US domestic AI chip production by localizing a key component of the advanced packaging supply chain.
TSMC September Revenue Hits Record NT$511.86 Billion
TSMC reported net revenue of NT$511.86 billion for September 2026, a 54.6% year-over-year increase, signaling sustained robust demand for AI chips ahead of its Q3 earnings call on October 15. This record performance underscores the company’s ability to capitalize on the AI boom despite ongoing capacity constraints in advanced packaging. The strong monthly results have bolstered investor confidence, contributing to recent stock price records.
TAIEX Hits Intraday High on Packaging Moat Narrative
On October 6, 2026, the Taiwan Weighted Index (TAIEX) brushed an all-time intraday high of 49,968.92, driven largely by TSMC’s share price surge. Market analysts highlight that TSMC’s CoWoS advanced packaging capabilities—not just its chip fabrication—are the binding constraint for leading AI chip shipments, making packaging capacity the key metric for investors. This narrative has fueled a rally in TSMC and related packaging suppliers.
Local view
Local Taiwanese media is closely watching the implications of the GlobalFoundries deal and upcoming earnings. United Daily News (UDN) reports that TSMC’s Q3 earnings call on October 15 will focus on operational expansion, including potential new fab constructions in Texas and alliances with major tech players like Elon Musk’s ventures. CTWANT notes that TSMC’s latest revenue report sets new highs for both monthly and quarterly operations, with CoWoS capacity expansion remaining the central theme for suppliers.
Context & numbers
- CoWoS Capacity Targets: TSMC’s CoWoS capacity is projected to double from ~130,000 wafers per month (end-2026) to ~260,000 wafers per month by end-2028, with expansion centers in Arizona (AP9, AP10) and Taiwan (AP7).
- Supply-Demand Gap: Analysts estimate the CoWoS supply-demand gap will narrow from 20% to 10% by end-2026 as capacity expands, though lines remain fully booked for 2026.
- CapEx Guidance: TSMC’s 2026 capital budget was raised to $60–64 billion, with ~70–80% allocated to advanced processes like N2 and N3, and advanced packaging.
On the radar
- Q3 Earnings Call: TSMC’s Q3 2026 earnings conference call is scheduled for October 15, 2026, where management will provide updated guidance on 2nm ramp-up and Arizona fab progress.
- ASML Earnings: ASML’s earnings report on October 14, 2026, will serve as a key indicator for AI chip demand sustainability, given its role as the sole supplier of EUV lithography tools.
- Texas Expansion Rumors: Reports suggest TSMC is evaluating a new Texas chip campus beyond its current $265 billion Arizona buildout, which could further reshape US manufacturing landscapes.
