Market cap is not relevant to cash flow concerns. Not to mention that Amazon no longer has a $1T+ market cap.

Which is frankly ridiculous for a company with a yearly revenue of about $500bn and a growth rate topping 10%, even at that scale.

Revenue is not the whole picture either, or growth rate.

If it is all loss making or tiny low single digit profit margin, then a $10B loss is still a $10B loss.

Amazon is making money, it's only lost a small amount over its entire lifetime.

Several of its divisions are making a ton of money and even retail could be making more, but it's constantly reinvesting to grow + it's a loss leader.
