With probabilities clustered near 50% for most contenders and Apple leading at 41% implied odds, traders see a tight race shaped by AI scaling, semiconductor demand, and cloud growth through late 2026. NVIDIA’s position at 19.5% reflects sustained GPU leadership and data-center expansion, though competition from custom silicon could cap gains. Alphabet at 31% benefits from search dominance and Gemini integration, while Microsoft and Amazon trail on Azure and AWS momentum. Key near-term catalysts include upcoming earnings, AI model releases, and regulatory moves on antitrust or export controls that could shift market-cap trajectories before year-end resolution.
