OpenAI Targets September IPO Following Legal Victory

OpenAI is moving forward with plans for an initial public offering, with leadership aiming for a market debut as early as September [1]. The move follows a federal jury’s decision to dismiss a lawsuit brought by Elon Musk, which had previously cast uncertainty over the company’s structure and financial future [1].

Key takeaways

• OpenAI is working with Goldman Sachs and Morgan Stanley to prepare confidential IPO paperwork for the Securities and Exchange Commission [2].
• The company is reportedly eyeing a valuation of approximately $1 trillion for its public debut [2].
• SpaceX, a competitor led by Musk, has also filed IPO paperwork and is targeting a valuation between $1.75 trillion and $2 trillion [2].
• Anthropic, another AI rival, is also expected to pursue an IPO as early as late 2026 [2].

A Financial Showdown Between Tech Rivals

The push toward public markets sets the stage for a high-profile financial rivalry between OpenAI CEO Sam Altman and Elon Musk [1]. Musk, who co-founded OpenAI in 2015 before departing in 2018, had alleged that Altman and co-founder Greg Brockman betrayed the organization's nonprofit mission [2]. A federal judge in Oakland, California, threw out the case on Monday, ruling that Musk waited too long to file his claims [2].

As OpenAI prepares its draft prospectus, it faces a competitive landscape where rivals are rapidly gaining ground. Anthropic, the developer of the Claude chatbot, recently reached a valuation of $900 billion, surpassing OpenAI’s last private valuation of $852 billion [2]. In response to these pressures, OpenAI is reportedly shifting its strategy to focus on enterprise customers and improving ChatGPT, while moving away from previously hyped products like the Sora video generator [2].

Market Implications and Future Outlook

The potential IPOs of OpenAI and SpaceX represent a significant moment for the tech industry, as both companies prepare to test public markets within months of each other [2]. SpaceX’s recent filings revealed substantial capital expenditures, with the company spending $7.7 billion on AI-related costs in the first three months of 2026 alone [2].

Investors are expected to monitor these companies closely as they navigate the transition from private to public entities. While OpenAI’s plans remain fluid, the company may file its confidential paperwork with regulators within days or weeks [1]. If successful, the offering would follow a period of intense scrutiny regarding the company's pivot toward a for-profit model backed by Microsoft [2].

Why it matters

The upcoming IPOs signal a broader trend of major AI and space-tech firms seeking public capital to fuel their operations and compete for market dominance. With OpenAI, SpaceX, and potentially Anthropic all eyeing public listings, 2026 is shaping up to be a pivotal year for the valuation and transparency of the world’s most prominent private tech companies [2]. The resolution of the legal dispute between Musk and OpenAI removes a significant hurdle, allowing the company to focus on its financial trajectory and product strategy in an increasingly crowded market [1].
