Memory chipmakers Micron and SK Hynix surge past $1 trillion market cap
Micron and SK Hynix have each surpassed $1 trillion in market capitalization, driven by surging demand for AI memory chips, highlighting the semiconductor sector's growing weight in global equity markets.

Memory chipmakers Micron and SK Hynix have each surpassed $1 trillion in market capitalization within days of each other, marking a milestone for the semiconductor industry. The surge reflects the AI boom's insatiable demand for high-bandwidth memory chips, which are critical for training large language models and other AI workloads.
SK Hynix, a South Korean company, saw its shares climb more than 250% since the start of the year, crossing the trillion-dollar valuation line last week. The firm has emerged as a key supplier to Nvidia, the dominant AI chip designer, cementing its position at the center of the global AI supply chain. Micron, the US-based rival, followed closely, also breaching the trillion-dollar mark. The rally in memory chip stocks has broader implications for foreign exchange markets, as South Korea's won and the US dollar are influenced by capital flows into the semiconductor sector.
