Why Did Tesla Stock Jump Today?

Tesla’s robotaxi momentum is driving the stock’s jump after the company expanded its driverless rollout and teased a major announcement for tomorrow. Shares rose about 6% near 2:27 p.m. ET, adding roughly 5.95% on the day. Tesla said it officially launched its driverless robotaxi service in Miami, Florida, starting July 3, marking the third U.S. state beyond Texas and California. The company’s post showed a limited geofenced service area. Investors also linked today’s gains to comments from Tesla vice president of vehicle engineering, Lars Moravy, who said July 7 would bring “cool news” tied to scaling efforts at Giga Texas. The competitive context is Tesla’s effort to build an AI-powered autonomous taxi and related robotics ecosystem.
