OpenAI is set to confidentially file IPO paperwork in the coming weeks, potentially as early as May 22, 2026, with plans to debut on the public market in fall 2026, likely September [1, 2, 3, 4, 5, 6, 7, 8, 9]. The company is working closely with Goldman Sachs and Morgan Stanley on the filing process [1, 2, 3, 4, 5, 6, 7, 8, 9].
The move follows a recent legal victory for OpenAI as a federal jury dismissed Elon Musk's lawsuit against the company in late May, removing a key obstacle to the IPO plans [10, 1, 2, 6]. Industry reports estimate OpenAI’s IPO valuation could reach approximately $1 trillion, potentially making it one of the largest AI sector public debuts to date [1, 3, 5, 9]. Its latest private valuation stands near $852 billion based on a recent funding round [1, 4, 6, 7, 8, 9].
OpenAI faces several challenges ahead, including missed internal revenue and user growth targets, the departure of executives, growing competition from rivals such as Anthropic and Google, and ongoing lawsuits related to its products [2, 11]. There are also reported internal disagreements over the timing of the IPO, with CEO Sam Altman favoring a quicker timeline than Chief Financial Officer Sarah Friar [11, 9].
The company aims to raise capital from the offering to fund massive investment plans in chips, data centers, AI model training, and talent necessary to grow its infrastructure. OpenAI’s infrastructure spending could exceed $1.4 trillion in the coming years [1, 2, 9]. The need to access public capital is heightened by rising costs related to AI compute resources and cloud services [9].
OpenAI is competing in a broader wave of major tech IPOs in 2026. Its rival Anthropic is also preparing an IPO filing, while SpaceX expects to file imminently and target a June public listing [1, 2, 4, 6, 7, 8, 9]. Wedbush Securities analyst Dan Ives said, "Getting to public markets first is very important, given this arms race going on. It sets a valuation, you're the first one to meet with investors on the road, and there's an advantage" [11].
OpenAI has stated, "We regularly evaluate a range of strategic options. Our focus remains on execution" in response to questions about its IPO timing [1]. The next major milestone is the expected confidential IPO filing with the SEC around May 22, which would signal the start of the formal public offering process [1, 2, 3, 4, 5, 6, 7, 8, 9].
