PANews reported on October 28th that Apple (AAPL.O)'s market capitalization surpassed $4 trillion for the first time on Tuesday, becoming the third major tech company to reach this milestone. Strong demand for its latest iPhone has eased concerns about its slow progress in the artificial intelligence race. Since the new phone was released on September 9th, Apple's stock price has risen by approximately 13%, marking its first positive return this year. Chris Zaccarelli, chief investment officer of Northlight Asset Management, said: "The iPhone contributes more than half of Apple's profits and revenue. The more phones it sells, the more users it brings into its ecosystem." Separately, OpenAI announced the completion of its long-awaited restructuring, pushing the market capitalization of its largest external shareholder, Microsoft (MSFT.O), back to $4 trillion, a milestone it reached in late July.PANews reported on October 28th that Apple (AAPL.O)'s market capitalization surpassed $4 trillion for the first time on Tuesday, becoming the third major tech company to reach this milestone.
