OpenAI Files for IPO One Week After Anthropic Submits Confidential S-1

AI Giant Submits Confidential Filing to Securities Regulators

OpenAI announced Monday afternoon that it has confidentially submitted an S-1 filing to the Securities and Exchange Commission, setting the stage for a potential initial public offering. The ChatGPT maker joins rival Anthropic, which filed its own confidential IPO paperwork just one week earlier. The artificial intelligence company carries a valuation of $852 billion following its March funding round, making it one of the most closely watched potential public offerings in the technology sector.

The company posted a candid announcement on its website acknowledging the filing. “We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it,” OpenAI stated in its Monday post. The firm emphasized it has not locked down a specific timeline for going public, noting that “it may be a while because there are things we want to do that are likely easier as a private company.” OpenAI characterized the decision as involving complicated tradeoffs while maintaining that the filing gives executives the option to pursue a public debut sooner if circumstances warrant.

The confidential filing mechanism allows OpenAI to submit its financial documents to regulators for review before making them available to the public and prospective investors. This approach typically gives companies flexibility in timing their market debut. Executives at OpenAI plan to take the company public as soon as the fourth quarter of this year, according to sources familiar with the matter, though no firm date has been set.

OpenAI Chief Financial Officer Sarah Friar told CNBC in April that maintaining public-company standards represents “good hygiene” for a business of OpenAI’s size. Friar explained that the company should “look and feel and act” like a public company, though she declined to comment on any specific IPO timeline during that April interview.

Company Plans Employee Liquidity Event Alongside Public Offering Preparations

OpenAI plans to facilitate a tender offer that will allow employees to sell shares at the latest valuation of $852 billion post-money, according to a person familiar with the plans who requested anonymity because the details remain private. This move addresses near-term pressure for liquidity among staff members who hold equity in the rapidly growing artificial intelligence firm. Tender offers have become increasingly common among late-stage private companies seeking to provide liquidity to employees without immediately pursuing a full public market debut.

The company has worked with major investment banks including Goldman Sachs and Morgan Stanley on the filing preparations, as CNBC previously reported. These two firms also appear at the top of SpaceX’s recent IPO filing, suggesting coordinated efforts among major technology companies preparing to enter public markets. The selection of these banking partners signals OpenAI’s intention to execute a high-profile offering when it ultimately chooses to proceed.

Sarah Friar recently stated that because “AI needs to garner trust in everything that we do,” OpenAI plans to reserve a portion of its eventual stock offering for average retail traders and investors. This approach mirrors the strategy that SpaceX announced for its own public offering, which aims to democratize access to shares beyond institutional investors.

ChatGPT Launch Propelled Company into Mainstream Recognition

The company rocketed into mainstream prominence following the launch of its ChatGPT chatbot in late 2022, fundamentally changing public awareness of artificial intelligence capabilities. ChatGPT now supports more than 900 million weekly active users, demonstrating unprecedented adoption rates for an AI application. The free app connects users to OpenAI’s advanced language models, enabling conversations, content creation, and problem-solving assistance that captured global attention.

OpenAI raised $122 billion in fresh capital during its March funding round, pushing its valuation to $852 billion. The company deploys this cash to develop increasingly advanced AI models and build the extensive physical data center infrastructure required to run these systems. Cloud computing capacity represents a critical bottleneck for AI companies, with training and inference operations consuming massive amounts of electrical power and specialized hardware.

However, recent reports indicate OpenAI has missed multiple internal revenue and user targets after facing fierce competition from Anthropic and Google. The competitive landscape has intensified dramatically, with Google’s Gemini AI model gaining increasing popularity among users and enterprise customers. Company executives have acknowledged internally that they need to reduce the number of “side quests” and avoid missing “this moment” in the rapidly evolving AI market.

Anthropic and SpaceX Create Competitive IPO Environment

Anthropic announced its confidential IPO filing on June 1, just one week before OpenAI’s Monday disclosure. The rival AI startup closed a funding round at a $952 billion valuation, surpassing OpenAI’s March valuation by a substantial margin. This competitive dynamic creates pressure for both companies to execute successful public offerings that maintain investor enthusiasm for the artificial intelligence sector.

SpaceX kicked off a roadshow last week for its highly anticipated public offering, which executives have scheduled for Friday. Elon Musk’s rocket company listed OpenAI, Anthropic, and Google as key competitors in the AI space within its filing documents. SpaceX operates an xAI business that competes directly with standalone AI companies, adding another dimension to the competitive landscape as these firms prepare for public market scrutiny.

Regardless of when OpenAI and Anthropic begin trading this year, they will become the second and third mega IPOs to follow SpaceX’s trillion-dollar offering. The timing and reception of SpaceX’s debut could significantly influence how Anthropic and OpenAI structure their own public offerings and choose their market entry windows.

Legal Challenges and Controversies Shadow Public Offering Plans

OpenAI emerged last month from a contentious legal battle with Elon Musk, who sued the company as it attempted to convert from its original nonprofit structure. The lawsuit raised questions about OpenAI’s governance and whether its transformation into a for-profit entity violated the organization’s founding mission to ensure artificial general intelligence benefits all humanity. The resolution of this dispute removes a potential obstacle to the company’s IPO plans, though concerns about corporate structure remain among some observers.

The company has also faced numerous claims that ChatGPT has caused harm to some of its youngest users, creating potential liability concerns for prospective public investors. OpenAI has denied these allegations, stating in response to one recent lawsuit that it bore no responsibility for the alleged harm. These legal challenges highlight the unique risks associated with AI companies, which face evolving regulatory frameworks and unprecedented questions about product safety and societal impact.

Company executives must navigate these controversies while building investor confidence in OpenAI’s long-term business model and growth prospects. The confidential S-1 filing represents a significant milestone, but the path to a successful public offering requires addressing stakeholder concerns about competition, profitability, regulation, and the fundamental sustainability of current AI business models.
