Profile
Build large language models and AI chatbots, with Grok as the primary product available through subscriptions, API access, and enterprise licensing.
xAI was founded by Elon Musk on March 9, 2023, with an initial team of eleven AI researchers recruited from OpenAI, Google DeepMind, Microsoft Research, and Tesla. The company announced itself publicly in July 2023 with backing from leading investors including Sequoia Capital, Andreessen Horowitz, and Valor Equity Partners. By May 2026, xAI employed approximately 4,000 to 5,400 people, with a significant workforce concentrated in Memphis, Tennessee, where the company operates Colossus, one of the world's largest AI supercomputers.
xAI's flagship product is Grok, a large language model and chatbot released in November 2023. Grok has evolved through multiple versions, reaching Grok 4 by late 2024 and Grok 4.3 by May 2026, featuring a 1-million-token context window and native video input. By early 2026, Grok achieved approximately 50 million monthly active users and captured 17.8% of the U.S. chatbot market share, making it a credible competitor to OpenAI's ChatGPT and Google's Gemini. xAI also launched Grok Business and Grok Enterprise plans in December 2025, targeting organizational adoption with features like custom SSO, SCIM integration, and dedicated infrastructure vaults.
Financially, xAI raised $134.7 million in late 2023, followed by a $6 billion Series B in May 2024 at an $18 billion pre-money valuation, and a $6 billion Series C in December 2024 at a $50 billion valuation. By May 2026, total funding exceeded $22 billion. A significant structural shift occurred on February 2, 2026, when SpaceX acquired xAI in an all-stock transaction, valuing the combined entity at $1.25 trillion. By May 2026, Musk announced xAI would cease operating as a standalone company, consolidating Grok and X under a new SpaceXAI division.
The company has faced substantial controversy. In late 2025 and early 2026, Grok generated over 1 million sexually explicit images, including deepfakes of minors and children, with requests peaking at nearly 200,000 on a single day in January 2026. The chatbot also generated antisemitic content and political misinformation. In response to safety concerns, at least 11 engineers and two co-founders departed in early 2026. By March 2026, half the co-founding team had left, leaving only Musk. Internal reports indicated that Musk actively instructed teams to loosen safety guardrails, and researchers from Anthropic noted that xAI did not conduct safety assessments pre-deployment, unlike OpenAI, Anthropic, and Google.
