ChatGPT’s $8 Trillion Birthday Gift to Big Tech

Saturday marks two years since OpenAI posted an oddly named widget called ChatGPT to the web. Its staffers placed bets on how many users it would accumulate, the highest estimate being 100,000. How wrong they were.

ChatGPT quickly became the fastest-growing app in history, with about 200 million active users today. When it first came out, social media was ablaze with examples of how this fluent little text box was a leap ahead of Amazon Inc.’s Alexa or Apple Inc.’s Siri. It could write poems and high school essays. It would probably reshape Hollywood and the education system. Some of that has come to pass, with schools rethinking how they assign homework, for instance, while its impact on other areas of life and business is still an open question.

What’s clear is that in two years, the biggest beneficiaries of the kind of AI that will one day “benefit all humanity,” according to Sam Altman, are a handful of tech firms. The six biggest have seen their market capitalizations grow in aggregate by more than $8 trillion since ChatGPT’s launch.

The tech sector has driven a 30% gain in the S&P 500 since January 2022, while small-cap companies have seen a more modest 15% return. That defies the trend of small- and mid-cap companies outperforming their larger counterparts over the two decades prior to ChatGPT’s launch.

Nvidia Corp. has meanwhile leapfrogged Advanced Micro Devices Inc. and Intel Corp. to become the world’s top chip company.

And cloud revenue has accelerated for Microsoft Inc., Amazon and Alphabet’s Google.
