According to the sources, Micron Technology reached a $1 trillion market capitalization for the first time after rising from about $70 billion 12 months earlier, while a newer report says the company doubled from $500 billion to $1 trillion in just 48 days. Gate data also shows SK Hynix gained more than 10% and moved above the $1 trillion mark. The surge is linked to investor enthusiasm for artificial intelligence infrastructure and strong demand for memory chips used in AI systems, highlighting a broader repricing of semiconductor companies seen as critical to AI buildouts.
