Tesla's third-quarter earnings fell 37% to $1.4 billion despite a revenue increase, marking the fourth consecutive quarter of profit decline. Sales rose due to a federal EV tax credit, but concerns about future demand persist. Musk emphasized diversifying the business beyond cars, including robotaxi services and AI products. Analysts express uncertainty about EV demand, and gross margins have declined. Musk's previous sales growth predictions have not materialized, and investor reactions to new vehicle offerings have been lukewarm.
