Samsung on Course for Biggest Quarterly Profit in Tech History With an $80B AI Windfall
Samsung Electronics estimated its third-quarter operating profit at 107.4 trillion won ($80.2 billion), a 782.5% year-over-year increase, driven by AI memory chip demand. Sales rose 126.6% to 195 trillion won. This would be the largest quarterly profit in tech history, surpassing Nvidia's $63.7 billion. Analysts expected higher sales, but the profit beat estimates. Samsung's shares fell 2.42% despite the record. According to the company, memory chips are a key driver of the profit surge.
