For example Volkswagen had $348 billion revenue in last year, while its market cap is only $66.5 billion.

Tesla, on the other hand had revenue of only $95 billion in the same period, but its market cap is a whopping $564 billion.

Now I understand that investors' expectations about the future potential of companies are priced in.

However, these discrepancies between market cap and revenue seem so huge, that I'm not sure if expectations for the future are enough to explain them.

Also, I would like to ask what metric is more relevant in determining the general economic importance of companies in the real world? Which company do you think is more economically important, Tesla or Volkswagen?
