One of the most important oil producers in the world is considering investment into Tesla Motors. https://www.bloomberg.com/news/articles/2018-08-12/saudi-fund-is-said-to-be-in-talks-to-invest-in-tesla-buyout-deal
Yeah, there is a lot of speculation floating around right now. Beside Saudi Oil, here are some others: Chinese government (this one makes the most sense to me) Norwegian National Retirement Fund (worth $125B) Apple Google Amazon
I hope not, they would utterly destroy any innovation Tesla is known for, and the company would be dead in water in 5 to 10 years imo.
