Tesla’s recent proxy statement has sparked confusion by listing Elon Musk’s AI company, xAI, as standing for “eXploratory Artificial Intelligence.” However, there is no public evidence that Musk or xAI officially uses or endorses this definition. In a 16-page filing dated September 5, 2025, Tesla described Musk’s major ventures as including “Space Exploration Technologies Corp., Neuralink Corp. and eXploratory Artificial Intelligence or 'xAI.'” The document referred to the company by its legal name, X.AI Corp., and simply as xAI in other sections. But despite this mention, no official source—such as xAI’s website, securities filings, Nevada articles of incorporation, legal documents, press releases, or public statements—defines the name as standing for “exploratory artificial intelligence.” A search of public records and online content reveals that the phrase “exploratory artificial intelligence” or “exploratory AI” does not appear in any official xAI materials. While the term “XAI” has been used in academic papers to refer to “explainable AI” or “exploratory AI,” these are distinct concepts and not linked to Musk’s company. Some niche blogs have claimed the name means “exploratory AI,” but none provide verifiable sources. Notably, Musk’s AI chatbot Grok used the phrase “exploratory AI” in nine posts on X between July and August 2025, accounting for nearly all such usage on the platform during that period. However, these posts did not equate the term with xAI. The company was formed in Nevada in March 2023 and officially announced by Musk in a July livestream. At the time, Musk stated that xAI’s goal was to build artificial general intelligence (AGI) “to understand the universe.” He has also emphasized his affinity for the letter “X,” which appears in SpaceX, the Tesla Model X, his child’s name X Æ A-12, and the domain X.com—originally a fintech startup that became PayPal and was later reclaimed by Musk. Despite Tesla’s reference, there is no indication that xAI’s name is meant to stand for “exploratory artificial intelligence.” The company has not clarified the meaning, and no authoritative source supports the claim. Tesla and xAI have not responded to inquiries about whether the acronym is intended to mean “eXploratory AI.”
