Tesla is discontinuing its luxury Model S and Model X electric vehicles in the second quarter of 2026 to focus on building its autonomous humanoid robot, Optimus. This decision, announced by CEO Elon Musk, marks a significant shift in the company's strategy, prioritizing the development of robots over its traditional vehicle lineup. The Model S and X, which have been instrumental in establishing Tesla's brand, will be phased out as the company aims to increase the autonomy of its products and move towards mass-producing robots. The sales of these vehicles have already seen a 40% drop in 2025, and the company has shifted its focus to cheaper models like the Model 3 and Model Y. This move is part of a broader transition to an autonomous future, with Tesla planning to produce a million units of Optimus robots in the space currently occupied by the Model S and X in its Freemont factory. The Optimus robot, currently in the early stages of research and development, is designed to learn by observing human behavior and can be trained to perform specific tasks. Tesla aims to begin significant production of Optimus around the end of 2026, with the long-term goal of having a million units in production. The company's focus on robots comes as it faces challenges in the automotive market, including a sales slump and competition from Chinese rival BYD. However, Tesla's ability to reach its autonomous goals is also hindered by geopolitical risks, limited chip production, and an industry-wide RAM shortage driven by generative AI workloads. Musk has hinted at a 'bigger announcement' regarding Tesla's semiconductor manufacturing capabilities, suggesting that the company may start manufacturing its own chips to address these challenges.
