Semicon Briefing

Samsung announces an investment program worth $648 billion in chips and AI – a volume equivalent to roughly one-third of South Korea's GDP. The market reacted skeptically to negatively: chip stocks fell after hours, and community comments warn of structural overinvestment in a sector that can barely produce enough DRAM to meet CPU demand.

TSMC is raising wafer prices for all Advanced Nodes, which account for 74% of wafer revenue – Nvidia, AMD, Apple, and Qualcomm are directly affected. New is the strategic side effect: Intel Foundry moves into focus as an alternative supplier, which could unexpectedly accelerate Intel's ongoing repositioning as a contract manufacturer.

ON Semiconductor (onsemi) signed a merger agreement on June 25, 2026, to acquire Synaptics (SYNA); Synaptics shareholders receive 1.35 onsemi shares per share. The deal strengthens onsemi's portfolio in touch and display ICs and further intensifies consolidation in the mid-range semiconductor segment.

China's state-owned semiconductor fund (Big Fund) became SMIC's third-largest shareholder via a record buyout on the Star Market, solidifying state control over China's most important wafer foundry. The move signals further nationalization of China's chip industry and increases geopolitical pressure on Western export control regimes.

SK Hynix intends to raise up to $29.4 billion through a Nasdaq listing of American Depositary Receipts – one of the largest tech fundraisings of the year. Proceeds are to finance capacity expansions and HBM development and position SK Hynix in direct competition with Samsung and Micron on the US capital market.

A widely noted Reddit analysis (935 upvotes, 272 comments) shows that seven Chinese companies – most of which went public in the last six months – are already shipping AI chips at H100/H200 level; Alibaba offers servers with 1.5 TB VRAM in one box. This demonstrates that US export controls have not stopped Chinese AI chip development but accelerated it – with immediate consequences for the competitive position of Nvidia and AMD.
