Bloomberg reports that ChatGPT’s launch didn’t just disrupt tech — it rewired Wall Street.
• Nvidia stock is up 979% since ChatGPT debuted.
• The seven biggest companies in the S&P 500 (Nvidia, Microsoft, Apple, Alphabet, Amazon, Meta, Broadcom) now make up 35% of its total weight.
• Nearly half of the S&P 500’s 64% growth since late 2022 came from AI-linked giants.
But even insiders see signs of a bubble. “Someone is going to lose a phenomenal amount of money in AI,” OpenAI CEO Sam Altman warned.
Huge upside — but huge fragility too.
