ELI5:how can Amazon lose millions year after year and stay in business?
gpt
Investors believe that Amazon is temporarily losing money in order to expand and control a lucrative market in the future.

Amazon isn't in the red because nobody's buying from them, in fact their sales are higher than ever before.  They are in the red because they are spending a lot and growing rapidly.  Once their growth slows then they'll be in a much stronger and will easily make up for a few years of negative profit (so the thinking goes).
