Tesla Inc. captured investor attention Monday with a series of cryptic social media posts, driving its shares higher.

The first post featured a video of a black, hubcap-like object with the Tesla logo spinning, ending with the numbers “10/7,” likely hinting at a product reveal scheduled for Tuesday. A second post showed a car in near-total darkness, with only its headlights visible.

Tesla’s stock climbed as much as 4% shortly after the market opened in New York, rebounding from a late-week slump following a record quarter of vehicle sales—a performance now difficult to repeat since U.S. federal EV subsidies have expired.

Tesla’s last major product addition was the Cybertruck nearly two years ago, which received a mixed reception. Executives have indicated a more affordable version of the Model Y is forthcoming to support sales in the absence of federal EV tax credits. Another anticipated release is the second-generation Roadster, whose prototype debuted in late 2017. CEO Elon Musk stated in February 2024 that Tesla aims to begin delivering the Roadster this year.
