Samsung Electronics has reached a $1 trillion market valuation after booming demand for chips used in artificial intelligence saw the world’s largest memory maker’s stock more than quadruple over the past year.The milestone came as the South Korean company’s shares rallied 11% early on Wednesday, making it only the second Asian firm after Taiwan Semiconductor Manufacturing Co. to hit the mark.Samsung, alongside memory peer SK Hynix and TSMC, sits at the heart of a transformation that has made Asia a cornerstone of the global AI ecosystem, pairing chipmaking dominance with expanding data infrastructure. That shift has fueled a powerful rally in regional tech stocks — SK Hynix and TSMC also reached record highs this month — as investors bet on sustained demand for advanced chips and computing capacity.
