APAC market cap rankings reshaped by AI, memory chips and Chinese banks
AI infrastructure and memory technology propelled new leaders while Chinese tech giants fell, according to GlobalData data for Q3 2026.
By Felo News Desk · Published
GlobalData says the third quarter of 2026 saw a dramatic reshuffle of Asia‑Pacific corporate market capitalisation, with AI infrastructure and memory technology driving the biggest gains and Chinese internet firms losing ground.
What happened
TSMC remained the region’s most valuable company at a $2.02 trillion market value, up 2.8% from June and 81.6% year‑on‑year, reflecting strong demand for advanced AI processors and advanced packaging. The total market capitalisation of the 50 largest APAC firms reached $13.74 trillion, a 4.7% rise from June and 49.5% higher than a year earlier.
What the reports add
GlobalData highlights that $555 billion of the $620 billion quarterly gain came from a single newcomer, ChangXin Memory Technologies (CXMT), which listed in Shanghai in July. Samsung Electronics grew to $1.27 trillion, up 225.6%, while SK Hynix surged to $956.3 billion, up 432.8%, driven by high‑value DRAM and HBM demand. MediaTek’s market value jumped 257.7% to $247.8 billion and Seagate rose 320.2% to $211.3 billion, reflecting AI‑related storage needs.
What was said
Murthy Grandhi, Company Profiles Analyst at GlobalData, said, “The market capitalisation of the 50 largest APAC companies was $13.74 trillion at the end of Q3, up 4.7% from the end of June and 49.5% on a year ago. But $555 billion of the quarter’s $620 billion gain came from one newcomer: ChangXin Memory Technologies (CXMT)… Without it, the group rose just 0.5%.”
How it came about
The surge aligns with broader AI‑driven demand noted in Felo’s recent coverage of AI‑related market moves, such as the bond‑yield swing story on 1 Oct 2026 that highlighted AI‑focused shares gaining on Wall Street. The rise of memory‑intensive workloads and the rollout of HBM4 chips have amplified the value of memory producers, while Chinese internet platforms like Tencent and Alibaba saw valuation declines as investors shifted toward hardware and banking sectors.
