Well it’s just the S&P. Other big indices may include it eg the Russell 3000. But it’s not quite as big of a deal as it seems because the market cap on which they scale is the float not the whole value of the company.

Thanks for pointing this out!

It seems obvious in retrospect, but the fact that SpaceX will be "valued" at $1.75 trillion after the IPO is irrelevant when only $75 billion worth of its stock will be publicly traded.

$75 billion in float-adjusted market cap puts it around 180-190th in the S&P 500. So sure, it will likely get in there eventually, but there's no rush to bend the rules to get it in right away.

Wait until you hear about float multiple Nasdaq is doing.

Spoiler alert - it's 5X for this.
