OpenAi prepares for a $1 trillion IPO by September

OpenAI, the Parent company of ChatGPT, is preparing for a massive $1 trillion Initial Public Offering (IPO) by September, making good on the company’s plans to leverage public funds in its pursuit of AI dominance.

The AI company is reportedly preparing an S-1 filing with Goldman Sachs and Morgan Stanley, targeting a stock market debut by September at a valuation exceeding $1 trillion. This comes a few days after Anthropic became the most valuable privately held AI company on the planet, following a Series H round that put its latest valuation at $965 billion. If OpenAI pulls off its planned IPO, it will succeed in knocking off Anthropic from its newfound perch.

A planned $1 trillion IPO for an AI company underscores the relevance of Artificial intelligence in the global tech ecosystem at the moment. This will put OpenAI in the same range as Nvidia, another AI juggernaut with a $4.5 trillion market capitalization. NVIDIA is the world’s largest AI chipmaker and the most valuable AI company following its 1999 IPO.

OpenAi reportedly choosing Goldman Sachs and Morgan Stanley as facilitators of its IPO suggests that the process is being prepared for maximum institutional participation. The S-1 filing is reportedly confidential, giving the AI company some measure of privacy around sensitive information such as company financials. Confidential S-1 filings are increasingly adopted by large companies to manage information and maintain privacy.

Ai investment is at an all-time high with major technology companies investing in infrastructure, platforms, and publicly traded AI firms. Big tech firms are big on AI infrastructure, following the lead of Nvidia, which has become one of the world’s most valuable companies from chip-making. Amazon, Google, Microsoft, and Meta poured an estimated $320 billion into AI Infrastructure in 2025 alone.

Amazon’s Project Rainier is one of the largest AI data centers in the world, costing over $11 billion and spanning about 1,200 acres. Google Cloud is scaling gigawatt-level AI capacity, powered by more than 2,000 liquid-cooled TPU pods, backed by a reported cloud backlog of around $240 billion. Meta operates 30 data centers globally and aims to achieve more than 10 GW of total capacity by the end of 2026. Microsoft is deeply aligned with OpenAi and is committed to building a $1 billion Data center in Kenya.

A successful $1 trillion IPO for OpenAi would mean a return to industry leadership for the pioneer AI company, which started the AI race with its flagship ChatGPT product. At a prospective $1 trillion valuation, OpenAI will become the second AI company to reach the $1 trillion milestone, cementing Artificial intelligence as a core pillar of today’s global tech ecosystem.
