Leading AI companies like OpenAI and Anthropic are unlocking billions in private share sales ahead of planned 2026 listings, raising questions about valuation authenticity and market readiness.
OpenAI’s confidential preparations for a stock market listing are unfolding alongside a striking wave of private-market liquidity for staff and early backers, with The Information reporting that current and former employees of OpenAI and Anthropic have collectively sold about $14 billion in shares over the past five years.
That figure underscores how leading artificial intelligence companies have already built a market for their equity long before any public debut. In OpenAI’s case, more than $9 billion of that total has come through employee share sales arranged by the company itself via tender offers, according to The Information. Those transactions have allowed insiders to cash out without forcing OpenAI to surrender control or open its ownership to public investors.
The mechanism is straightforward. In a tender offer, the company sets a price and buys shares from existing holders. In a private secondary sale, current shareholders sell stakes to new buyers, but no new stock is issued by the company. Either route can ease pressure on employees who have accumulated paper wealth, while preserving the private-company structure and postponing the scrutiny that comes with a public listing.
The scale of these deals has turned private share trading into a kind of release valve for the AI boom. Reuters has previously noted that OpenAI’s October 2025 secondary transaction valued the company at about $852 billion on a post-money basis, giving sellers a reference point well ahead of any IPO pricing. That kind of mark can be lucrative for insiders, but it also raises a central question for investors: whether those private valuations reflect enduring business fundamentals or simply the appetite of a frothy secondary market.
Karthik Krishnan, an associate professor of finance at Northeastern University, told Reuters that it is difficult to know whether figures such as OpenAI’s should be treated as true valuations or as expectations about what shares might fetch later in resale markets. That distinction matters because public markets will eventually impose a harder test, with audited accounts, formal disclosures and daily price discovery replacing private negotiations.
The issue of access is just as important as valuation. Anthropic has warned investors against unauthorised secondary share platforms, highlighting the limits of private-company equity, which is not the same as freely traded public stock. Even when transfers are approved, they still depend on company permission, valuation work and a clean settlement process.
There is also a growing sense that the AI sector’s route to the public markets may be shaped by other high-profile listings. Axios has reported that OpenAI and Anthropic are both aiming for 2026 flotations, and that they may be studying SpaceX’s investor outreach as a model. That approach, which emphasises education and predictable pricing rather than a more volatile auction-style process, could appeal to companies whose businesses are unusually complex and whose disclosures are likely to attract intense attention.
But any listing will arrive under far more scrutiny than a private sale. According to Tom’s Hardware, a coalition of 42 US state attorneys general has opened a sweeping investigation into OpenAI’s advertising practices, data handling, safety policies and treatment of minors. That inquiry comes just days after reports of a confidential IPO filing and adds another layer of pressure as the company weighs its next corporate step.
For now, the broader story is less about a single float than about the way elite AI companies are already monetising equity behind closed doors. The public offering, when it comes, will not create that market; it will test whether the valuations formed in private can survive exposure to public investors.

This includes over $9 billion in employee share sales facilitated by OpenAI through tender offers. These sales have provided liquidity to employees and early investors, reducing the pressure for a public offering. However, the company has been cautious about unauthorized secondary share platforms, emphasizing the need for company approval and proper valuation for such transfers.

The subpoena targets various aspects of the company’s operations, including advertising practices, data handling—especially concerning minors and health information—user engagement strategies, safety protocols, and model behavior like sycophancy. This move follows OpenAI’s confidential filing for an IPO, potentially valuing the company at $1 trillion.

SpaceX, in collaboration with Goldman Sachs, began engaging with potential investors as early as January, emphasizing investor education due to the company’s complexity and frequent announcements, such as acquisitions and partnerships. This proactive and transparent approach contributed to a smooth IPO launch and is seen as a likely model for Anthropic and OpenAI. The article notes that these AI companies may follow suit with a fixed-price offering, deviating from the typical U.S. IPO auction method. As the year progresses, both Anthropic and OpenAI appear to be gauging public market interest in preparation for their own IPOs.
- https://www.axios.com/2026/05/20/openai-ipo-spacex-musk – OpenAI is preparing a confidential initial public offering (IPO) filing, according to sources close to the matter. This move, also reported by other media outlets, appears strategically timed to coincide with the upcoming IPO unveiling of Elon Musk’s SpaceX. Both OpenAI and SpaceX are engaging major financial institutions like Goldman Sachs, Morgan Stanley, and JPMorgan Chase to support their respective offerings. Industry speculation has long suggested that both OpenAI and its competitor Anthropic are targeting IPOs in 2026, likely between Labor Day and Thanksgiving. OpenAI recently prevailed in a legal challenge from Musk, who has expressed intentions to appeal. An OpenAI spokesperson emphasized that while the company is exploring various strategic options as part of its governance process, the primary focus remains on execution.
