Tesla, valued at $830 billion, faces skepticism about its ambitious revenue projections from autonomous ride-hailing and humanoid robots, with estimates reaching up to $10 trillion. Despite a 44% stock drop, the company relies heavily on EV sales, which are declining amid increasing competition, particularly from low-cost producers like BYD. Analysts predict further earnings declines, potentially leading to a 50% drop in stock value over the next year, challenging Musk's vision of surpassing the market caps of major tech companies.
