Samsung Electronics is reportedly working with TSMC to use TSMC's 3nm process to produce base dies for Nvidia's next-generation custom HBM chips, according to the Seoul Economic Daily, marking the first time Samsung has collaborated with TSMC at the HBM manufacturing stage. The base die integrates the memory controller previously housed on the GPU, and together with a 60% smaller physical layer, it is said to deliver up to 30% more memory bandwidth and 15% lower power consumption than standard HBM4E. Sources cited TSMC's yield on this process at over 90%, versus about 60% for Samsung's comparable 2nm process, supporting consolidation of production at TSMC. Demand is rising, with UBS projecting about 61.5 billion gigabits of HBM needed next year, up 91%, while supply is expected to fall short by about 10%.

- Taiwan Semiconductor Could Partner With Elon Musk’s Terafab, but It Has 1 Condition
- Taiwan Semiconductor Just Proved Why It's a Top AI Investment
TSMC reported a strong third quarter driven by AI chip demand, with revenue up 51% in New Taiwan dollars and 41% in US dollars, and profit up 69% year over year. The stock still fell during the trading day after earnings, which the author attributes more to the broader market outlook than to the results. CEO C.C. Wei said demand is very robust with no sign of slowdown, and that the earlier guidance of a 50% CAGR for AI-related chip revenue from 2024 to 2029 may be too low. The author notes the stock trades at 18 times next year's earnings and 27 times trailing earnings; if TSMC meets 2027 expectations and the valuation holds at 27 times, that math implies a 50% rise, though the author stresses this is only arithmetic and not a certainty.
- What Does Broadcom (AVGO) Face As AI Chip Supply Turns Into A Bottleneck?
Broadcom (AVGO), with a market value of US$1.6 trillion, is competing with other AI chip clients such as Nvidia and Apple for capacity at TSMC, which is expanding its advanced manufacturing and reporting record profits in 2026. The article argues that access to TSMC's leading-edge lines is key for Broadcom to keep its edge in custom XPU and networking chips while scaling its VMware-based Private AI Cloud. The bullish case is that securing long-term wafer supply would strengthen the outlook for multi-year demand for AI XPU and Ethernet products. The bearish side is that TSMC acts as a chokepoint for Broadcom's lowest-margin, most capital-intensive products, so any allocation shortfall or pricing shift could pressure gross margins.
- TSMC Is Spending up to $64 Billion This Year. Here's Why That's Great News for Investors.
TSMC plans to spend $60 billion to $64 billion this year on factories and equipment, about a third of trailing-12-month revenue, which the article presents as a sign of coming growth. CFO Wendell Huang linked the spending to long-term customer demand, including agentic AI, and said spending from 2026 through 2028 should be significantly higher than in the previous three years. Third-quarter revenue reached a record $46.7 billion, up 41% year over year, with fourth-quarter guidance of $52.3 billion to $54.3 billion, and profit margin rose to 51.1% from 45.7%. The article notes geopolitical risks in Asia and says overseas plants such as Arizona cost more to run and may weigh on future margins. The stock trades at 19 times 2027 earnings estimates, with consensus calling for 28% earnings growth next year.
- TSMC's (TSM) Record AI Demand Comes With a Growing Cost
TSMC (TSM) shares rose 13.14% over the six months to October 15, following a record quarter in which revenue grew 41.2% to $46.7 billion and net income jumped 68.7%, mainly on AI-related chips. The company guides next-quarter revenue to $52.3–54.3 billion and full-year revenue growth of about 44%, with demand also coming from CPUs for AI servers and networking chips. Capex is planned at $60–64 billion for 2026 plus $100 billion for US expansion, while gross margin slipped from 67.7% to 66.4% during the 2nm ramp. The article warns that if customers cut AI spending before new fabs reach full production, both earnings estimates and valuation could come under pressure.

Hai Phong Thermal Power (HND) disclosed an appellate ruling in a coal supply dispute with Dan Ka Mineral, under which the court accepted the plaintiff's appeal and ordered the company to pay nearly VND 115 billion, including a coal price difference of over VND 80.15 billion and interest of over VND 34.65 billion. The dispute stems from a 2021 contract, with disagreement over price adjustments after global coal prices rose sharply in 2022. Duong Son Ba, the company's general director, was arrested on 21 May 2026 over alleged forgery of documents of an agency or organisation, and the board dismissed him from the post on 13 October, with no successor yet announced. In the first half of 2026, the company reported net revenue of nearly VND 6,081 billion, up 8%, and after-tax profit of over VND 508 billion, up nearly 25%.
- Iran threatens to use the 'father of all missiles' to strike adversaries' energy facilities
Major General Mohammad Reza Naqdi, senior adviser to the IRGC commander, said at a rally in Sari on October 18 that Iran has prepared the most advanced missiles and will respond to any aggression. He warned that energy infrastructure and investments belonging to powers Tehran deems aggressive in the region could fall within Iranian missile range. His remarks answered US President Donald Trump's threat to use the GBU-43/B MOAB, often called the 'mother of all bombs' and weighing about 14 tons, against Iran's energy infrastructure and nuclear sites. Naqdi said Iran also possesses these bombs, having seized some that failed to detonate in the 12-day war, and called Trump's impatience a 'public admission of defeat'.
- Strategy on verge of golden cross, just weeks after bitcoin flashed same bullish signal
Strategy (MSTR) is about to form a golden cross, when its 50-day average rises above its 200-day average, possibly as early as Monday, just weeks after bitcoin showed the same bullish signal. The company holds $69.81 billion in bitcoin, and its stock has had two earlier golden crosses followed by big rallies: from $15.57 in September 2020 to $127.29 by February 2021, a 717% gain, and from $25.29 on March 2, 2023 to a peak of $473.83 in November 2024, up 1,774%. The article stresses the signal is unreliable, though: since 1999 MSTR has had 19 golden crosses, and only 10 were followed by a higher price 12 months later, a 50% hit rate, with a median 12-month return of just 3.3%. The two worst cases, in 2001 and 2007, were followed by a 61% loss.
- Director of the HCMC Institute of Economics, Natural Resources and Environment: Four major corporations have raised plans to invest in Vietnam, but pulled back when asked about power capacity
At a seminar co-organized by Tien Phong newspaper and the HCMC Department of Construction on October 16, TS. Phạm Viết Thuận said the city should treat infrastructure as an integrated system rather than focusing only on transport. He argued that 11 main and 13 secondary infrastructure categories, including power, water drainage, industrial zones and logistics, need to be synchronized for the city to develop its economy. To address flooding, he proposed surveying 159 flood-prone points and building ecological lakes at major spots. He also noted that four large corporations had considered investing in Vietnam but withdrew when asked about grid power capacity. Department director Trần Quang Lâm said capital mobilization and land policy need further study, while traffic congestion, flooding and pollution remain the city’s top priorities.
- Live updates: Bitcoin tags $83,000 and slips back as chip stocks lead a rebound
Bitcoin climbed from an overnight low near $80,700 to just above $83,000 early Monday, then slipped back to about $82,400 as sellers stepped in, and was up 0.3% over 24 hours. The bounce followed tech stocks, with Nasdaq 100 futures up 1.1%, snapping a weeklong 5.5% selloff, and an ETF tracking chipmakers jumping 3%. WTI crude recovered to $98.55 after touching $96.72, as the U.S. warned citizens across 12 Middle East locations of possible flight cancellations and airspace closures, raising fears of fresh strikes on Iran and disruption at the Strait of Hormuz. In Europe, the Stoxx 600 fell 0.8% after protests in France. Bitcoin would need to move through $84,000, its ceiling on October 13 and 14, to signal that the tech rebound is lifting it too.
- Baystreet . ca - When Might October Nasdaq Correction End ?
The Nasdaq Composite (QQQ ETF) is 6.96% below its 52-week high after falling 5.52% last week, close to the 10% threshold for a technical correction. The article says high oil prices, sustained by Iran's control of traffic through the Strait of Hormuz, keep September CPI and PPI rising, and that Iran wants higher oil prices to hurt the Republican Party before the midterm elections, so the correction in beaten-down stocks may continue. CoreWeave (CRWV) lost 25.21% last week, closing just 3% above its yearly low, while bears holding a 17% short float bet its $50 billion debt is unsustainable. Nebius (NBIS) fell 25% and Twilio (TWLO) dropped 15.6%, while Autodesk (ADSK), Salesforce (CRM) and Adobe (ADBE) drew buying. The article suggests volatility may ease after the midterms.
