xAI Acquisition
xAI was acquired by SpaceX for $250B on 2 February 2026.
Before the acquisition xAI had raised $36B across 5 funding rounds.
SpaceX announced on 2 February 2026 that it had acquired xAI in an all-stock transaction valuing xAI at $250 billion and SpaceX at $1 trillion, creating a combined company worth about $1.25 trillion in the largest merger ever completed and the largest acquisition of a private target on record. xAI became a wholly owned subsidiary, bringing the Grok family of large language models, the X social platform it had absorbed in March 2025 and the Colossus supercomputer campus in Memphis under the same roof as SpaceX's launch business and Starlink satellite network. Elon Musk framed the combination as a vertically integrated engine spanning rockets, space-based connectivity, direct-to-mobile communications and frontier AI, with plans for orbital data centres, and the deal was widely read as preparation for a SpaceX initial public offering. The $250 billion value was a modest step up from the $230 billion post-money set by xAI's $20 billion Series E four weeks earlier. xAI's revenue was reported in the low hundreds of millions of dollars annualised at the time against a monthly cash burn of about $1 billion.

|---|---|---|---|---|---|
| Jan 2026 | Series E | NVIDIA; Fidelity; StepStone Group; Qatar Investment Authority; Cisco Investments; Baron Capital; Manhattan Venture Partners (MVP); Valor Equity Partners; Tesla | $20B | $230B | xAI, 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 2025 | Secondary | Neptune 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. |
| Jul 2025 | Strategic investment | SpaceX (lead); Launchbay Capital; Natural Capital | $5.3B | - | xAI raised about $5 billion of new equity in July 2025 as part of a $10 billion financing that also included $5 billion of debt arranged by Morgan Stanley, with SpaceX committing $2 billion of the equity in its first investment in a sister Musk company, as reported by the Wall Street Journal on 13 July 2025. The raise followed xAI's all-stock merger with X in March 2025, which had valued the combined group at $113 billion, and funded the expansion of the Colossus supercomputer in Memphis and the training of Grok 4. Other equity participants included existing xAI backers such as Valor Equity Partners, Fidelity and Kingdom Holding together with secondary specialists including Launchbay Capital. Elon Musk said the investment reflected plans to integrate Grok into Starlink customer support and, potentially, Tesla's Optimus robots. xAI, founded in 2023 and headquartered in the San Francisco Bay Area, develops the Grok family of large language models and was reported to be spending about $1 billion a month at the time. |

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. |
| May 2024 | Series B | Redstone.VC; SquareOne Capital; Fidelity; Andreessen Horowitz; HOF Capital; Sequoia Capital; Driving Forces; Valor Equity Partners; Kingdom Holding; Vy Capital; Autopilot Ventures | $6B | $24B | xAI, Elon Musk’s generative AI startup focused on developing truthful and advanced AI systems to understand the universe, announced its Series B funding round of $6 billion on May 26, 2024.
