Google’s parent reinforces itself through AI (Gemini), search dominance, YouTube growth, cloud services, and its self-driving startup Waymo—continuing to innovate beyond its core ad business .
6. Meta Platforms (≈ $1.4–1.8 T)
Facebook, Instagram, WhatsApp—Meta stays relevant through digital ads. Investments in metaverse (VR/AR), AI chatbots, and smart glasses push it into the next-gen social/web frontier .
7. Broadcom (≈ $0.9–1.1 T)
A semiconductor heavyweight riding the AI hardware wave. As part of the “BATMMAAN” bloc, Broadcom leverages AI-driven demand to climb market ranks.
8. Tesla (≈ $0.9–1.1 T)
Tesla remains a tech titanic brand—electric cars, autonomous driving, energy storage, and AI robotics. The rollout of FSD and Cybertruck ahead sustains its valuation around the $1 T mark .
9. TSMC (≈ $0.85–1.1 T)
As the key chipmaker for Apple, NVIDIA, AMD and others, TSMC’s node-leading fabs (2 nm and soon 1.4 nm) are critical to global tech infrastructure—making it Asia’s semiconductor backbone.
10. Tencent (≈ $0.55–0.60 T)
China’s digital behemoth excels in social (WeChat), gaming (the world’s biggest), payments, and cloud. Despite regulatory cycles, Tencent stabilizes around ~$600 B valuation .
🧭 What Drives These Titans?
- AI Explosion: NVIDIA, Microsoft, Alphabet, Apple, Broadcom—and even Tencent—are riding the AI wave. Cutting-edge chipsets, cloud ML services, and integrated AI features are core value enhancers.
