Grok is not an independently valued company; it is an AI product developed by xAI, founded by Elon Musk. In February 2026, SpaceX acquired xAI in a deal valuing xAI at approximately US$250 billion, while SpaceX was valued around US$1 trillion. However, this does not mean Grok itself was worth US$250 billion.

The valuation covered xAI’s entire business, including its technology, infrastructure, employees, intellectual property, and AI models. Following the acquisition, xAI became part of SpaceX rather than remaining independently valued.

Later private-market activity reportedly valued SpaceX at about US$1.54 trillion, with higher valuations discussed ahead of its planned public offering.
