Apple

With a market cap that has hovered between $3 trillion and $3.5 trillion since 2024, Apple remains the world's most valuable company and the first ever to cross the $1T, $2T, and $3T milestones. Its iPhone generates over $200B in annual revenue, and Apple Intelligence — its on-device AI suite — launched in late 2024 to over 1.5 billion active devices globally. The company's services segment now contributes $100B+ annually, making it a software giant disguised as a hardware brand. Covered in Walter Isaacson's landmark biography 'Steve Jobs' and more recently the Apple TV+ documentary series.
