Three years after OpenAI released ChatGPT on Nov. 30, 2022, Bloomberg reports that AI-driven investment has powered a 64% rise in the S&P 500 through Nov. 29, 2025. Nvidia leads gains — shares are up 979% and revenue forecasts top $200 billion — while Big Tech concentration (seven firms about 35%) and energy demand reshape market winners and losers.
