Tesla

Tesla is the world's most valuable automaker and one of the most important AI companies, founded in 2003 and led by Elon Musk. Tesla designs and manufactures electric vehicles, energy storage systems, and solar products, while simultaneously developing some of the most advanced AI systems in the world.

Tesla's AI efforts span two major domains. First, Full Self-Driving (FSD) is one of the largest real-world AI systems, using a neural network-based approach that processes data from cameras and sensors to enable autonomous driving. Tesla's fleet of millions of vehicles generates enormous training data, giving it a data advantage that traditional automakers cannot match. Second, Optimus is Tesla's humanoid robot project, designed to perform dangerous, repetitive, or boring physical tasks. Cybercab, Tesla's purpose-built robotaxi with no steering wheel, pedals or mirrors, entered production in April 2026 and began carrying paying riders in Austin on September 3, 2026. The same day the National Highway Traffic Safety Administration opened an audit query covering an estimated 1,000 vehicles into how Tesla self-certified a car with no manual controls against federal safety standards written for cars that have them; Zoox's comparable audit ran for years before ending in a capped exemption, so the outcome governs how quickly the service can spread beyond Austin.

Tesla operates one of the world's largest AI training clusters (using both NVIDIA GPUs and custom Dojo chips) and employs a massive AI team. The company's vertically integrated approach — designing its own AI chips, building its own training infrastructure, collecting data from its own vehicles, and deploying AI in its own products — makes Tesla unique among both automakers and AI companies.

In March 2026, Tesla announced Terafab — a joint venture with SpaceX, xAI, and (as of April 7, 2026) Intel to build a vertically integrated chip foundry. Terafab targets one terawatt of AI compute output per year — roughly fifty times current global AI chip production. In August 2026 Tesla and SpaceX confirmed the production site as Grimes County, Texas, about an hour northwest of Houston, committing $16.8 billion to a first phase covering more than 100 million square feet and at least 3,000 workers, with later phases projected to reach roughly $119 billion; a smaller Terafab research facility broke ground at Giga Texas earlier in the year. The pilot line plans 3,000 wafers per month by 2029, scaling toward 1 million wafer starts per month and 100-200 billion chips per year on Intel's 18A and 2 nm nodes. Tesla taped out its AI5 chip on April 15, 2026 (powering FSD v15 and the next-generation Optimus), with AI6 tape-out planned for December 2026. AI5 is dual-sourced at Samsung's Taylor, Texas fab and TSMC Arizona — Musk has explicitly framed this as breaking the foundry monopoly. Terafab, combined with the restarted Dojo3 program (repositioned in January 2026 for space-based AI compute), cements Tesla's move from single-foundry reliance toward a fully in-house silicon stack.
