Samsung profit surges on AI chip demand

Samsung is expected to report an 18-fold increase in profit, driven by surging demand for its memory chips used in artificial intelligence. The company's strong performance has boosted confidence among chip stock investors, who see Samsung as a key player in the AI trade. Meanwhile, Samsung's union leader saw a $26 billion bonus victory turn into disappointment. The company is also preparing for a new battle with LG in China over robot vacuums.
