After watching the CW interview, I think that she is low-balling the Tesla market share in her bull case of 17.5% of the EV market.
In 1908 when Ford brought out the Model T, there were initially a lot of players in the new market but this quickly consolidated to what was known as the big three:
Automotive industry in the United States - Wikipedia
> The
motor vehicle industry began with hundreds of manufacturers, but by the end of the 1920s it was dominated by three large companies:
General Motors,
Ford, and
Chrysler, all based in
Metro Detroit. After the
Great Depression and
World War II, these companies continued to prosper, and the U.S. produced nearly three quarters of all automobiles in the world by 1950 (8,005,859 of 10,577,426).
We can expect a lot of new players to enter the EV space, and a lot of consolidation of EV/auto brands over the next 20 years. The initial lead Tesla has might manifest as something as high as 40% market share peak as their production manages to match demand. Having the best product at the cheapest price only serves to increase Tesla's lead with economies of scale. Ford was around 50% market share for quite a decade or so. There is a huge first mover advantage when it comes to new tech. Because Tesla has the best product at cheaper prices I expect them to be supply constrained for a decade. The pressure of switching to EVs is only going to go up for governments, consumers and automakers. I also expect a very steep growth rate for Tesla EVs in the next decade. Here are my estimates for the trajectory of Tesla's EV market share:
2020: ~20%
2025: 25%
2030: 35%
2035: 30%
2040: 20%
