Nvidia recently made history as the first publicly traded company to reach a $4 trillion market cap, briefly becoming the world's most valuable company. This milestone reflects Nvidia's transformation from a gaming hardware maker to the dominant provider of GPUs and software powering AI technologies. Since ChatGPT's launch in late 2022, Nvidia's stock has surged 871%, with its data center division driving a 73% year-over-year revenue increase. The company's valuation now rivals the GDP of major nations like Japan and India, far outpacing competitors AMD and Intel. Despite emerging competition from tech giants developing in-house solutions, experts believe Nvidia will maintain its leadership position in AI hardware for the foreseeable future.
