Nvidia has reported record sales of $30 billion, surpassing Wall Street's earnings estimates, as the demand for its chips continues to grow. This surge is driven by nations building their own artificial intelligence models, which require Nvidia's advanced chip technology. The company's performance highlights the ongoing momentum in AI technology, despite some concerns about a potential bubble in the market. Nvidia's results underscore its pivotal role in the AI boom, as more countries invest in developing AI models in their own languages.
