He left in May amid a fight with Trump. In November, Tesla shareholders approved a new pay package for Musk.The firm said 75% of shareholders with voting rights backed Musk's 10-year pay deal, which could net him $1 trillion over that time by boosting his stake in Tesla by more than 423 million shares. Though shares dropped significantly in the first quarter of 2025, they are back on track with an all-time closing high of $489.88 last month, after Musk said it had been testing driverless vehicles in Austin, Texas.
