Apple's market value crossed the $4 trillion mark for the first time in trading on Oct. 28. This record was the result of a strong rise in the company's stock price in recent weeks, with the iPhone 17 models released in September showing higher sales than their predecessors, CNBC explains.

Apple has long remained one of the outsiders of the S&P 500 index: in April, the fall reached 31% since the beginning of the year, recalls Bloomberg. Since then, however, its value has risen more than 50%, and last week its share price hit its first record high in 2025. Investors and analysts reacted to signs of higher-than-expected demand for the new iPhone lineup - reinforcing hopes that the company's long-awaited device refresh cycle had begun.

Apple shares rose by 0.3% at the beginning of the session, after which they lost some of this growth. They have gained in price in 11 of the last 12 trading sessions, the channel notes.

At the same time, Microsoft's capitalization soared back above $4 trillion after the deal with OpenAI was announced. Microsoft's shares gained about 3% on this news.
