Uber has never once turned a profit, and is allowed to continue running their business. If you’re a small business owner running an ebay or ecom business, and you claim losses for 3 out of 5 years in a row, it’s likely that the IRS will audit you, and could deem you a hobby. Amazon is often cited as not generating a profit for many years, but is now profitable. For them, it was somehow okay to run a business making no profit! So like, how come small businesses can’t claim losses, but big corps can?
Because they manage to attract investment.
As long as investors are willing to give cash in exchange for equity, a company can operate on that cash and run at a loss.
