Jan 2026Series ENVIDIA; Fidelity; StepStone Group; Qatar Investment Authority; Cisco Investments; Baron Capital; Manhattan Venture Partners (MVP); Valor Equity Partners; Tesla$20B$230BxAI, Elon Musk's AI company behind the Grok chatbot, raised $20 billion in an upsized Series E funding round announced on January 6, 2026, exceeding the $15 billion target. Investors include Valor Equity Partners, Fidelity, Qatar Investment Authority, Nvidia, and Cisco as strategic investors, though the query lists additional investors like Baron Capital, Cisco Investments, Manhattan Venture Partners, StepStone Group, and Tesla which align partially with reported participants. The round valued xAI at approximately $230 billion post-money. During the first nine months of 2025, xAI generated $210 million in revenue while burning through $9.5 billion in cash, highlighting the capital-intensive nature of AI development with monthly expenditures exceeding $1 billion primarily on chips and data centers. The funding will support expansion of data centers and Grok models, amid xAI's reported 600 million monthly active users across X and Grok. This round follows high cash burn and positions xAI behind competitors like OpenAI ($500B valuation) and Anthropic ($350B), with subsequent developments including a $2B Tesla investment and a merger with SpaceX valuing xAI at $250B in February 2026.
Dec 2025SecondaryNeptune Digital Assets (lead)$300K-xAI is an artificial intelligence company developing advanced AI systems, including the Grok large language model and the Colossus supercomputer cluster, with a mission to accelerate human scientific discovery. Neptune Digital Assets Corp., a blockchain infrastructure and frontier technology company, entered into an agreement on December 11, 2025, to invest US$300,000 in xAI by acquiring 3,601 shares, providing early exposure to AI innovation. The investment closed in early 2026, aligning with Neptune's strategy to diversify into high-growth technologies like AI alongside its existing SpaceX holdings and digital assets. Following the investment, SpaceX announced plans to acquire xAI, with xAI shareholders expected to receive 0.1433 SpaceX shares per xAI share. Neptune's 3,601 xAI shares are anticipated to convert into approximately 516 SpaceX shares, enhancing Neptune's exposure to space and AI integration. This positions Neptune at the intersection of AI, space exploration, and blockchain.

Feb 2025Undisclosed stageMichael Baßler$28M$1.5BxAI is Elon Musk's artificial intelligence company focused on developing frontier AI models and capabilities. The company raised $27.7 million in a venture round on February 25, 2025, led by investor Michael Baßler, at a post-money valuation of $1.5 billion. This funding round preceded a much larger development in early 2026 when SpaceX acquired xAI in an all-stock deal that valued the combined entity at $1.25 trillion, with xAI valued at $250 billion and SpaceX at $1 trillion. The acquisition reflects Musk's ambitions to create an integrated stack spanning space launch, orbital bandwidth, and frontier AI models. Prior to the February 2025 round, xAI had raised $70 million in a Series B round in February 2024 at a $318.25 million valuation, and $25 million in Series A funding in April 2022 at a $121.76 million valuation. The company's burn rate has been substantial, with reports indicating approximately $1 billion in monthly cash burn as of early 2026.

Investors included Andreessen Horowitz, Sequoia Capital, Valor Equity Partners, Qatar Investment Authority, and others aligning with the queried list such as Fidelity and Blackrock in related reports. The funds support AI infrastructure like purchasing 100,000 Nvidia chips and building the 'Colossus' supercomputer with 100,000 H100 GPUs. This round positions xAI as a top AI contender behind OpenAI, with product advancements like Grok-1.5 featuring improved contextual and image understanding integrated into the X platform. Total funding raised by xAI in 2024 reached $11 billion.
