The stock of NVIDIA can buy the 230 smallest S&P 500 companies. Which are still quite big companies. I recently learned this fact and I think it is pretty wild.
The SP500 could merge into one company, regulation permitting.
It's the owners of the Nvidia stock who potentially could trade their Nvidia stocks for the other 230 companies stocks. But then they have no Nvidia stocks anymore, on the other hand.
Nvidia just made graphics cards, at a time when games were still being written for MS-DOS. Nobody was to imagine the real money to be made from repurposing these graphics cards for crypto and now this AI 'application'.
