Tesla’s stock declined after its recent second-quarter earnings due to a pincer-like movement on gross and operating margins caused by rising costs, including raw material costs and increased costs of providing financing, and increased research and development in connection with robotaxi and Optimus. Revenue expectations from the robotaxi rollout have been pushed out because Tesla isn't meeting expectations previously laid out by CEO Elon Musk in terms of the scale of the rollout. Management's commentary on the rollout during the earnings call also dampened enthusiasm over a massive scaling in 2026. However, progress is being made on the next version of full self-driving (FSD) software, v15. In April, Musk outlined that "it wouldn't be right for us to go to like very large scale unsupervised FSD when we know that there are software improvements in the pipeline." Musk believes v15 will be released in late 2026 or early 2027. On the recent earnings call, Tesla's vice president of AI, Ashok Elluswamy, told investors that "The currently operating robotaxi fleet is already running early versions of the v15 FSD software." Elluswamy noted that Tesla had "seven major improvement tracks" for v15, developed in parallel, with "40% of those tracks merged together, and that's what's running in the fleet right now." Unsupervised robotaxi had notched up 380,000 miles without any notable incident.
