Elon Musk is in line for a trillion-dollar pay day, but only if he reaches ambitious targets. Protesters have hounded car dealerships selling Teslas after Musk appeared to do a Nazi salute at an inauguration event last January.

The deal also requires him to sell 20 million electric cars, 10 million self-driving subscriptions, a million humanoid robots and a million robotaxis over 10 years.
