Tesla has been growing revenues 50% on average for the past 10 years.
Most other car makers are roughly flat. This year ICE cars, globally, are in decline.
Tesla will grow 50% on average for at least next 5 years.
Also, there has been a ton of money looking for a place to invest for the past 20 years. And there are plenty companies that are investable. Just recently we had monster IPOs from DoorDash, AirBnb, Snowflake and others.
At the same time there are many more companies that one could invest in but doesn't so it's lazy to attribute "lost of money available" to outsized successes like Tesla or Snowflake.
