Nvidia's success in becoming the most valuable company in the world is a result of smart decisions made years ago that positioned it as a leader in the AI chips market. Founded in 1993, Nvidia initially focused on GPUs for gaming and design before shifting to AI, where its chips outshined traditional CPUs for data processing. CEO Jensen Huang's foresight in creating CUDA programming tools early on paved the way for Nvidia's dominance in AI chips, with its latest Grace Hopper Superchip boasting record-breaking speeds. Despite facing competition and geopolitical challenges, Nvidia has established itself as a go-to choice for large language models like ChatGPT due to its superior performance and software suite. While threats loom on the horizon, for now, Nvidia continues to soar, with its stock split and significant contributions to the S&P 500's success this year.
