Apple

Apple holds the top spot with a market capitalisation of approximately $3.5 trillion, driven by its unrivalled ecosystem of hardware, software, and services. The iPhone maker's Services division — encompassing the App Store, Apple TV+, Apple Music, and iCloud — now generates over $100 billion in annual revenue with gross margins exceeding 70%, making it the most profitable segment in corporate history. Apple Intelligence, the company's on-device AI suite launched with iOS 18, added a wave of iPhone upgrade demand heading into 2026, enabling Apple to outperform #2 NVIDIA by nearly 6% in market cap growth over the past quarter.
