OpenAI Surpasses SpaceX to Become the Most Valuable Private Company Globally
OpenAI has recently overtaken SpaceX to claim the title of the world’s highest-valued private company, now boasting a valuation comparable to that of Elon Musk, its longtime rival and the wealthiest individual on the planet.
Record-Breaking Stock Sale Elevates OpenAI’s Valuation
According to recent reports, OpenAI completed a significant transaction where current and former employees sold approximately $6.6 billion worth of shares to prominent investors such as Thrive Capital, SoftBank, and T. Rowe Price. This deal catapulted OpenAI’s valuation to an unprecedented $500 billion, surpassing SpaceX’s $400 billion and pushing ByteDance, TikTok’s parent company, to third place with a $220 billion valuation. Notably, OpenAI’s worth was estimated at $300 billion just months earlier in 2025.
Massive Investment in AI Infrastructure: The Stargate Initiative
This surge in valuation coincides with OpenAI’s aggressive funding efforts for its ambitious Stargate project-a $500 billion, four-year plan to develop cutting-edge data centers across the United States. Collaborating with industry giants like Oracle and SoftBank, OpenAI aims to establish a robust AI infrastructure capable of supporting the next generation of artificial intelligence advancements. The initiative was initially unveiled during a high-profile White House event earlier this year.
Expanding Capacity and Strategic Partnerships
Last month, OpenAI revealed plans to add five new Stargate data centers, including a flagship facility in Abilene, Texas. These expansions will bring the project’s total planned capacity close to 7 gigawatts, backed by over $400 billion in investments over the next three years. CEO Sam Altman emphasized the critical role of computational power in realizing AI’s full potential, stating, “AI’s promise hinges on building the compute infrastructure that powers it, ensuring equitable access and enabling future breakthroughs.”
Altman further highlighted on his personal blog that the AI industry must reach at least 10 gigawatts of compute capacity to avoid having to prioritize certain AI applications over others, underscoring the scale of resources required for continued innovation.
Securing Advanced Hardware Through Key Collaborations
To support its data center expansion, OpenAI has forged partnerships with leading semiconductor companies including Nvidia, Samsung, and SK Hynix. Nvidia alone has committed up to $100 billion in investments to supply the necessary chips, reinforcing the strategic importance of hardware in AI development.
Elon Musk’s Wealth Milestone and Ongoing Disputes with OpenAI
Coinciding with OpenAI’s valuation milestone, Elon Musk briefly became the first individual to reach a net worth of $500 billion, though his wealth has since slightly decreased to around $499 billion. The majority of Musk’s fortune is tied to Tesla, where he holds approximately 12% ownership. Tesla remains one of the world’s most valuable publicly traded companies, with a market capitalization of $1.4 trillion. Recently, Tesla’s board proposed a $1 trillion compensation package to retain Musk’s leadership.
Fractured Relationship Between Musk and OpenAI Leadership
Despite Musk’s foundational role in establishing OpenAI in 2015, his relationship with the organization has deteriorated significantly. He has engaged in a public dispute with CEO Sam Altman, culminating in a federal lawsuit filed last year in Northern California. Musk alleges that Altman misled him by transforming OpenAI from a nonprofit research entity into a network of for-profit affiliates without proper disclosure.
The lawsuit accuses Altman of consolidating control over the nonprofit’s board, engaging in conflicts of interest, and diverting both talent and technology from the nonprofit to benefit financially from the for-profit ventures.
Disparity Between Company Valuation and Leadership Wealth
While OpenAI’s market value continues to soar, Sam Altman’s personal net worth remains relatively modest, estimated at around $20 million according to recent financial assessments.
