Yahoo Finance analysis indicates that despite Apple's late start in the AI sector, its Siri AI is poised to become its biggest growth opportunity. The article quotes Apple CEO Tim Cook, who described Siri AI as a "thoroughly rethought, powerful, deeply personal, and seamlessly integrated" competitive weapon, with monetization potential from 2.5 billion active devices and over $1.5 billion in paid subscriptions. Analysts believe that if Siri AI can drive an iPhone upgrade cycle, normalize memory costs, and scale iCloud Plus monetization, Apple's stock price could rise 38.2% from its current $325.65 to $450 by 2027. To date, Apple's stock has risen 19.92% this year and 40.58% over the past year.
