NVIDIA

NVIDIA became the most valuable company in the world in June 2024 at a market cap of $3.34 trillion, supplying the H100 and H200 GPUs that power virtually every major AI training run. Its CUDA ecosystem lock-in, Blackwell architecture promising 30x performance gains over the previous generation, and expansion into networking via InfiniBand positioned it as the indispensable infrastructure of the AI era. This performance leap outperforms #2 OpenAI's hardware reliance, as NVIDIA's chips are the backbone of 95% of AI model development.
