AI Mania Reshapes Stock Market Three Years After ChatGPT
Three years ago, OpenAI launched ChatGPT, which sparked a huge interest in artificial intelligence (AI) on Wall Street.
This excitement has changed the stock market a lot.
Big tech companies like Nvidia, Microsoft, and Apple have become even more valuable, and their stocks have gone up a lot.
Nvidia, which makes chips for AI, has seen its stock rise by almost 1000%.
But not all companies are doing well.
Some, like LivePerson and Chegg, have lost a lot of value because people think AI might replace what they do.
The stock market is now more dependent on just a few big companies, which some people worry could be risky.
Overall, AI has become a big part of the stock market's success.
ChatGPT's release in 2022 sparked a significant AI investment frenzy in the stock market.
Big Tech companies like Nvidia, Microsoft, and Apple have seen substantial stock increases, driving the S&P 500's 64% jump.
Nvidia's stock has surged 979% since ChatGPT's launch, with projected revenue exceeding $200 billion this year.
Electricity providers like Vistra Corp. have also seen significant stock increases due to AI's high energy demands.
Some companies, particularly in software, staffing, and advertising, have struggled, with stocks like LivePerson and Chegg falling over 97%.
