OpenAI Confidentially Files for IPO at Up to $1 Trillion Valuation

OpenAI has officially entered the race to go public. On June 8, 2026, the artificial intelligence giant behind ChatGPT confidentially submitted paperwork for a U.S. initial public offering, setting the stage for what could be one of the most significant tech listings in history.

According to sources familiar with the matter, OpenAI is targeting a valuation of up to $1 trillion — a figure that would place it alongside the most valuable companies ever to debut on public markets. The IPO could come as early as September 2026, though specific terms and a formal timeline have not yet been disclosed.

This move comes as the broader AI sector heats up in a rush toward public markets. Anthropic, OpenAI's key rival, has also confidentially filed for its own IPO, while SpaceX — led by Elon Musk — saw its own IPO become dramatically oversubscribed with more than $10 billion in institutional orders. The trio of listings signals a pivotal moment for investor appetite in AI and deep tech.

OpenAI acknowledged in a statement that certain strategic objectives may actually be easier to achieve as a private entity, hinting at the internal debate that has surrounded its transition from a nonprofit research lab to a for-profit corporation. The company has undergone significant restructuring over the past year in preparation for this milestone.

For investors and tech enthusiasts alike, the OpenAI IPO represents far more than a financial event. It is a referendum on the future of artificial general intelligence, the monetisation of large language models, and whether the biggest bet in tech history will pay off at scale.
