Key Takeaways
- Elon Musk's xAI has been acquired by SpaceX (SPCE) in a landmark $250 billion deal, creating a combined entity with an estimated valuation of $1.25 trillion.
- Prior to the acquisition, xAI successfully closed an oversubscribed Series E funding round, raising $20 billion and achieving a $230 billion valuation.
- The acquisition is strategically designed to integrate xAI's advanced AI capabilities with SpaceX's (SPCE) infrastructure, aiming to address compute limitations and accelerate AI development.
- Funds from the recent capital raises are earmarked for massive infrastructure expansion, including building large AI computing clusters in Memphis, Tennessee, equipped with Nvidia (NVDA) H100 GPUs.
Elon Musk's artificial intelligence startup, xAI, has been acquired by his aerospace company, SpaceX (SPCE), in a monumental $250 billion transaction announced on February 3, 2026. This strategic merger creates a formidable combined entity with an estimated valuation of $1.25 trillion, positioning Musk's ventures at the forefront of AI and space technology integration. The deal utilized a "triangular merger" structure, designed to protect SpaceX from potential legal liabilities and debts associated with xAI.
The acquisition follows a significant period of capital raising for xAI. In early January 2026, xAI successfully closed an oversubscribed Series E funding round, securing $20 billion in investment. This round exceeded its initial target of $15 billion and propelled xAI's valuation to approximately $230 billion. This latest funding round saw participation from investors including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, Baron Capital Group, Nvidia (NVDA), and Cisco Investments.
The substantial capital infusion is primarily directed towards expanding xAI's compute infrastructure, a critical component for advanced AI development. xAI is actively building large AI computing clusters, including a third data center located near Memphis, Tennessee. These facilities are being equipped with a massive supply of Nvidia (NVDA) H100 GPUs, with plans to expand capacity to 50 million H100 equivalent units within the next five years. The company also deployed over 165 Megapack energy storage systems from Tesla (TSLA) at its Memphis site to mitigate power fluctuations.
The integration of xAI into SpaceX is driven by a clear financial rationale. While xAI reportedly incurred a burn rate of approximately $1 billion per month through the first nine months of 2025, SpaceX generated an estimated $8 billion profit on $15-16 billion revenue in 2025. This acquisition provides xAI with access to SpaceX's cash-generating capabilities, crucial for funding its extensive infrastructure buildout and competing with other AI giants.
Previously, in September 2025, xAI had reportedly sought $10 billion in funding at a $200 billion valuation, following an earlier $10 billion debt and equity round that valued the company at $150 billion. These efforts underscore xAI's aggressive pursuit of capital to fuel its rapid growth in the highly competitive AI sector. The company's flagship AI model, Grok, is central to its offerings, with Grok 5 currently in training.
