Semiconductors & AI Chips Weekly Briefing

January 23, 2026

TSMC warned Nvidia of capacity limits, Intel posted a Q4 loss, and Micron predicted memory shortages until after 2026; plus, Nvidia faced a piracy lawsuit, and more.

• TSMC warned key customers, including Nvidia and Broadcom, of capacity constraints due to surging demand for advanced AI chips, despite reporting strong Q4 results and accelerating their 2nm growth plans and US facility timelines. ¹²³⁴
• Nvidia, which CEO Jensen Huang claimed is now TSMC's largest customer, faced significant geopolitical friction as US restrictions led to H200 shipments hitting roadblocks in China, resulting in reports that Chinese firms might turn to the black market. ⁵⁶⁷⁸⁹
• The intense competition in the AI chip space continued, with Nvidia reportedly boosting the performance of its next-gen Rubin processors to defend against AMD’s Instinct AI accelerators; meanwhile, a class-action lawsuit accused Nvidia of using pirated books to train its AI models. ¹⁰¹¹¹²
• Intel reported a Q4 net loss of $600 million on $13.7 billion in revenue—a 4% decline—but still beat expectations, though the company cautioned that industry-wide supply chain constraints would limit growth moving forward. ^1314151617
• Micron indicated that the memory chip shortage, accelerated by AI demand, is expected to persist beyond 2026 as the company simultaneously progressed major US investments, including breaking ground on a $100 billion megafab, and acquired a Powerchip fab site in Taiwan for $1.8 billion. ^1819202122
• South Korean memory giants SK Hynix and Samsung faced pressure from the US, which threatened 100% tariffs if they did not meet investment requirements; both companies continued production expansions, with SK Hynix advancing its packaging plant in Indiana and Samsung improving 1c DRAM yields. ^23242526
• Other developments included Marvell receiving FTC approval for its $3.25 billion acquisition of Celestial AI and later announcing plans to acquire XConn Technologies, while AMD aggressively expanded its AI software ecosystem through releases like ROCm 7.2, Nitro-AR, and the Adrenalin AI Bundle. ^2728293031
