Apple (AAPL) closed above a $5 trillion market capitalization for the first time, marking a significant milestone for the consumer electronics giant. The company's quadrupled revenue under Tim Cook's leadership reflects its robust business model and market dominance, particularly in iPhone sales, which have grown from $47 billion to nearly $210 billion.
Microsoft (MSFT) introduced its Maia 300 custom AI chip, aiming to enhance its competitive edge in the artificial intelligence market. The move comes amid a broader selloff in AI-related shares, as investors reassess the sector's heavy debt burdens and valuation risks, which have hit stocks like Nvidia particularly hard.
