> AirBnB realized they can use this float in investing in low risk treasuries and generate a little revenue. (It is unlikely that equities is an asset class that is used) Yet the quote specifically states they're buying stocks: > He used a portion of capital from the balance sheet to buy stocks I have a hard time believing they're returning $5 million a month by holding just low risk treasuries. That's $60m a year which would take a consistent investment of $2.5b at an annual 2.5% interest rate (near the current 5-year yield). Bonds have been moving rapidly so they probably need to keep it shorter term than that which would require an even larger float.
