At this valuation this is a very risky investment because the current price already accounts for future growth, so there is very little margin for safety or meaningful upside left. The sole purpose of this IPO is for early investors and employees to cash out. I wouldn't touch this stock with a 10 foot pole.
Other stocks have routinely priced in future value and the market has forgotten. Uber and Tesla both priced in full self driving cars. No talks about that any more, barely a thing.
What if they build superintelligence?
