The purchase was made by a foundation on Friday, the documents show. It was made at the same time as Tesla's chairman Robyn Denholm said in a Bloomberg interview that he saw great benefits with a replacement program aimed at Musk that can become worth up to 1,000 billion dollars if Tesla achieves a number of milestones when it comes to market value and profitability.
Tesla's share rises by over 7 percent in futures trading after the news of Musk's share purchase. If the increase persists, Tesla has regained the entire decline that the share has had this year.
