Elon Musk’s xAI Raises $20 Billion in Series E Funding Round
Three weeks ago, Elon Musk’s artificial intelligence company, xAI, made headlines when it announced that it had secured $20 billion in a Series E funding round. The latest development in this story reveals that Tesla, the electric car giant, is among the investors in xAI.
In a recent letter to shareholders, Tesla disclosed that it had invested $2 billion in xAI, the startup responsible for the Grok chatbot and Musk’s social media company, X. This investment solidifies Tesla’s position as a key player in the AI space, alongside other notable investors like Valor Equity Partners, Fidelity, Qatar Investment Authority, Nvidia, and Cisco.
Interestingly, this investment by Tesla in xAI was not without controversy. Last year, Tesla shareholders voted against the proposal to authorize an investment in xAI, with a significant number of abstentions leading to the measure’s rejection. Despite this setback, Tesla proceeded with the investment, citing xAI’s alignment with its latest master plan as a key reason for the decision.
According to Tesla’s shareholder letter, the investment in xAI is part of the company’s broader strategy to bring AI into the physical world, as outlined in its recent master plan. The agreement between Tesla and xAI paves the way for potential collaborations in AI development, building on their existing relationship, which includes the use of Tesla’s Megapack batteries to power xAI data centers and the integration of xAI’s Grok chatbot into Tesla vehicles.
Looking ahead, xAI has ambitious plans to develop AI for humanoid robots, similar to Tesla’s Optimus, further solidifying the synergy between the two companies. Tesla also highlighted its ongoing efforts in physical AI and robotics, including the development of its Optimus robot, semitrucks, and autonomous capabilities.
