If SpaceX ($SPCX) was in the $SPX now, AI-related stocks would be 51% of the index. With Anthropic and OpenAI coming public, add them to the $SPX in 2027 and AI would be ~55% of the $SPX. The last time a single theme was >50% of the $SPX was the railroads in the 19th century. Here is the list (I use Michael Cemblast's list, it is as good as any list I've seen.) https://t.co/B9uvzTWQCO

Quoted context

These are the quoted author’s words.

AI-related stocks (defined by the JPM basket) now make up 49% of the S&P 500. Those same 41 companies account for about two-thirds of the S&P 500’s year-to-date market cap change. https://t.co/u2QfL0xvQH
