TSMC should benefit as CoWoS packaging is relieved, because the extra volume flows back into its front-end fabs. Per TrendForce, TSMC is taking CoWoS from about 130k wafers a month at end-2026 to 260k by end-2028, while 2nm and 3nm also grow. C.C. Wei said outside packaging capacity helps the wafer business, still most of TSMC. OSATs can win packaging while TSMC owns the bigger upstream prize. The view fails if CoWoS alternatives ramp and TSMC's HPC wafer growth stalls. x.comÂ
TSMC's record revenue shows AI demand still steepening, with supply, not demand, the binding constraint through 2027. August revenue hit NT$514.8 billion, up 53.3% year over year and the first month above NT$500 billion, with the quarter tracking up 49%, yet the ADRs opened down 2% on fears AI spending has peaked. Street checks show Q3 above guidance and CPUs becoming a second driver on agentic workloads, and easier comps should improve year-over-year prints through year-end. x.comÂ
TSMC captures more value as advanced nodes and packaging expand revenue beyond wafer volumes. In Q3 2026, N2 rose from 3% to 8% of wafer revenue, HPC reached 68%, and revenue grew 50.9% in TWD versus 9.6% wafer-shipment growth. N2 ramping squeezed gross margin, yet TSMC generated nearly $15B in free cash flow after $13.8B of capex. TSMC expects 2026-28 capex significantly above the prior three years; Wendell Huang says revenue growth should outpace capex growth if they do their job right. x.com … Show more
TSMC remains a long: Intel winning foundry business is only Intel picking up work where TSMC lacked capacity, partly because TSMC wasn't aggressive enough adding capacity, rather than a competitive threat. x.comÂ
TSMC may lose pricing power as performance gains shift from shrinking transistors to stacking, interconnects and optics, while logic folding could make older processes competitive. Despite strong leading-edge demand, investors may overestimate the profit share its node leadership can retain. Its cautious expansion and past reluctance toward advanced packaging suggest a risk-averse culture that protects returns but could leave it late to disruptive technologies and key customers. x.comÂ
Leading-edge wafer demand is bullish for semiconductor equipment makers because TSMC is already at over 100% utilization on those nodes. Per Ben Bajarin, rack-scale pods drive more wafers across categories. Close collaboration at the leading edge also gives equipment makers and TSMC visibility into plans years ahead. x.com x.comÂ
TSMC's conversion of 4nm/5nm capacity to 3nm to clear a backlog stretching to 2028 shows 3nm is the bottleneck, and TSMC controls the queue. Broadcom flagged the constraint publicly. The mix shifts toward 3nm premium pricing, with AI accelerator growth guided in the mid-to-high 50s% over five years, so every conversion is margin expansion disguised as logistics. TSMC is trading handset volume for HPC and AI margin, leaving Qualcomm, MediaTek and other non-Apple customers to absorb the squeeze. … Show more
TSMC's conservative delay in high-NA adoption will be its downfall as Intel's stitching advances sooner. TSMC's larger-mask alternative requires changing the entire stage and is projected for production by 2033; Intel's stitching is substantially derisked and could be ready for volume production in 2027 at the earliest. TSMC's CoWoS and CoPoS shortcomings add to the concern. x.comÂ
TSMC's strong AI demand is straining supply, while solid company fundamentals and attractive semiconductor valuations make an abrupt stop to its advance unlikely. TSMC's Wendell Huang expects 2026-28 capex to be significantly higher than in the previous three years to support customer growth; he says most capex is tied to long-term demand. x.comÂ
TSMC sits at the end of the money trail as agentic AI reprices the chip supply chain, and Google's $40 billion Anthropic deal is the clearest proof. That deal is effectively a prepaid inference contract for 5GW of TPU capacity over five years, and every TPU flows through TSMC, where advanced-node demand runs about 3x supply. Agentic AI burns 10-100x more compute per session than a chatbot. CoWoS packaging is the tighter bottleneck, with prices rising 10-20% a year, double logic wafers. x.com … Show more
TSMC's shifting cost structure is pressuring gross margin despite revenue and EPS beats. TSMC reported Q3 gross margin of 66.4%, down from 67.7% in Q2, and another decline is guided next quarter; Arizona is expected to drag gross margin by 2-4%. TSMC is checking AI data-center progress as it plans wafer capacity, while reiterating long-term AI demand strength. Price hikes may be next, given management's commitment to protect shareholder interests. x.com x.comÂ
TSMC's capacity-constrained growth is holding margins through its costly 2nm ramp. Its Q4 revenue guide of $52.3-54.3B beats $49B consensus, implying 14% sequential growth, with 65-67% gross-margin guidance; planned Q4 capex is $19-23B versus $13.8B last quarter. World Trade Securities maintains Overweight and a $620 target. TSMC is also in talks to run Elon Musk's proposed Texas Terafab; additional fab and equipment demand depends on a deal. x.com x.comÂ
