Are you sure it's worth more than Porsche? Porsche is owned by VW and has a complicated equity structure.
According to Google Finance Tesla has 10.70 Billion in Market Cap, while Porsche is at 12.69. Last week Tesla was trading at around over 100 per share, so at that time it had a higher valuation. Surprised it didnt go up after they announced on Friday they were going to add more charging stations to allow cross country trips and the ability to use their stations to recharge in 30 minutes, and that they might be willing to sell the technology to other car companies since it wont work with their chargers.
