On Monday, Tesla surpassed GM in market value, making it the most valuable U.S. automaker. It’s also the first time in modern history that this title was held by a car maker not based in Detroit. The gravitational pull to Silicon Valley is immense, today.

I subscribe to Alan Murray’s CEO Daily newsletter and his overarching comments were as follows: GM sold 10 million cars last year. Tesla sold 76,230 cars (albeit high value cars – my 2 cents). And Tesla lost three quarters of a billion dollars last year. Are we partying like it’s 1999?

This is an expectations game.

Elon Musk crafted an electric sports car that was actually cool and Tesla is certainly one of the leaders when it comes to autonomous vehicle technology. If Tesla is the company that transitions our economy to both electric and autonomous vehicles, then is a current market cap > $51 billion justified?

I don’t know.

But given how often we talk about electric and autonomous vehicles on this blog (in the context of city building), I thought it would be worthwhile to also talk about where Wall Street is putting its money and placing its bets.
