TSMC Posted $16 Billion in September and Tapped GlobalFoundries for a $2B New York Packaging Deal

NEW YORK — TSMC posted about $16 billion in September revenue and TSMC tapped GlobalFoundries for a $2 billion deal to make AI chip-packaging components in New York. Both were announced today, Oct. 8 — and together they say the AI hardware money train is still running at full speed.

The revenue numbers first. TSMC reported September revenue of NT$511.86 billion, up 54.6% from the same month a year earlier, according to the company's official monthly revenue report. That's roughly $16.03 billion. The only blemish in the report, per Barron's, is that September slipped 0.6% from August's all-time monthly high of NT$514.8 billion. Zoom out and the quarter is a record: third-quarter revenue reached NT$1.49 trillion — about $46.7 billion — up 51% year over year and above the NT$1.46 trillion analysts expected, according to FactSet data cited by Barron's. January-to-September revenue is up 41.1%. The quarter also beat TSMC's own guidance of $44.6 billion to $45.8 billion.

What makes the numbers matter is where the demand sits. For months, AI-bubble warnings have piled up next to genuine supply strain in memory chips, and the two stories have started to blur. TSMC's quarter separates them, per Startup Fortune: the money is flowing into the logic chips doing the actual computing. Memory is the tight market — Samsung and SK Hynix have spent 2026 warning that DRAM and NAND are stretched, with conventional DRAM contract prices expected to rise 10% to 15% in the fourth quarter. Meanwhile Samsung's own profit surged ninefold, per Barron's. The compute side of the AI buildout, the part TSMC owns, isn't short of buyers: Nvidia and Apple remain its two biggest customers, and neither has shown signs of pulling back orders.

The market, characteristically, yawned. TSMC's Taiwan-listed shares fell about 1.4% on Thursday, and its U.S.-listed ADR had dropped 2.1% in the previous session to $472.20, per Coinpaper. The reason wasn't the numbers — it was the backdrop: higher oil prices and elevated Treasury yields weighed on tech broadly, with AMD, Broadcom, Marvell and Intel all sliding in early trading, per Barron's. GlobalFoundries, by contrast, rallied: GFS rose roughly 6% in morning trading on the back of its own announcement, bucking the market's drawdown.

And that announcement is the other half of today's story. GlobalFoundries said it has signed a five-year manufacturing agreement with TSMC, valued at $2 billion, to produce silicon interposers at its Malta, New York, facility — establishing the first U.S.-based source of the components for TSMC's CoWoS advanced-packaging ecosystem. The component, as Reuters describes it, sits beneath processors and memory chips inside advanced AI packages and enables them to communicate at high speeds. "Advanced packaging is becoming increasingly critical to delivering the performance, power efficiency and scale required for next-generation AI systems," said Ed Kaste, GlobalFoundries' senior vice president of CMOS Business, in the company's announcement. The agreement gives GlobalFoundries a supplier role inside TSMC's packaging supply chain — not a second source for TSMC's full chipmaking, as RuntimeWire notes: GlobalFoundries makes one component of the package while TSMC remains the customer whose system integrates it.

Why this deal exists tells you what the bottleneck is. Advanced packaging has become a major constraint on AI chip production — demand for the technology exceeds available manufacturing capacity, per Reuters. When TSMC began producing Nvidia's Blackwell generation of GPUs at its Arizona plant last year, the final products still had to be round-tripped to Taiwan and back for final assembly, The Register reports. TSMC has contracted Amkor for CoWoS-compatible packaging services in the U.S. and broken ground on its own advanced packaging facilities in Arizona, but neither is expected online until 2028 and 2029. GlobalFoundries' Malta expansion closes the hole: volume production is expected to begin ramping in the first half of 2028, the agreement has an initial five-year term, and it provides a framework for future capacity expansion as demand grows.

Put the two announcements together and the picture is the money train in motion. TSMC's second quarter already showed the shape of it — revenue up 36% and net income up 77.4%, per Coinpaper — with high-performance computing accounting for 66% of revenue and advanced nodes of 7nm and below generating 77% of wafer revenue, including a growing contribution from the new 2nm process. Industry observers say TSMC may need as much as $64 billion in annual capital spending and could still be underbuilding for AI demand, per MarketBeat — which also notes multiple TSMC executives, including CEO C.C. Wei, recently made small open-market stock purchases. And Wall Street is already asking who pays for the AI boom, as Broadcom's $50 billion OpenAI financing scramble showed.

The New York angle is the one to watch. A Taiwanese giant spending record amounts on advanced chips and an American chipmaker expanding in Malta, New York to package them — that's a U.S. manufacturing and jobs story hiding inside a revenue report. The AI buildout runs on silicon from Hsinchu and, increasingly, from upstate New York.
