Nvidia briefly surpassed a $5 trillion valuation in October 2025, marking a historic moment for the company driven by surging demand for its AI chips. With an 81% market share in data center chips, Nvidia's stock skyrocketed 12-fold since the launch of ChatGPT in November 2022. The company reported over 60% growth in sales and profits for the October quarter compared to the previous year, exceeding Wall Street expectations. Nvidia now anticipates around $500 billion in revenue for 2026, buoyed by the unveiling of its next-generation Vera Rubin chip. Founded in 1993 by Jensen Huang, Nvidia initially focused on graphics processing units (GPUs) for video games. Its breakthrough into the AI sector gained momentum with the rise of ChatGPT. While Nvidia became the ninth company to reach a $1 trillion valuation in 2023, it continues to expand its offerings beyond GPUs. The company is now investing in full server racks and software to optimize AI workloads and is positioning itself as a leader in emerging fields like robotics and quantum computing. Nvidia’s partnerships include collaborations with Uber for self-driving cars and a $100 billion investment in OpenAI to enhance AI data center capacity. Despite its rapid growth, Nvidia faces challenges, including fierce competition from AMD and the need to demonstrate ongoing growth after several strong quarters. Concerns about an AI bubble linger, and US export controls have restricted sales in China, once a key market. Nevertheless, Nvidia is pushing ahead, with its new Rubin chips set to launch in late 2026 and major cloud providers like Microsoft and Google Cloud lined up for deployment. Huang's vision includes a future where every vehicle is autonomous, reflecting his broader ambition to diversify Nvidia's business into autonomous driving and robotics.
