Analysis
The Transaction
OpenAI completed a secondary tender offer worth roughly $7 billion on August 10, giving current and former employees a window to sell vested shares at an $852 billion company valuation, according to CNBC. The sale had been anticipated since OpenAI closed its record-breaking $122 billion primary funding round in March, and it gives employees a way to realize the value of stock compensation without waiting for a public listing, according to TechCrunch. Coverage continued into the following morning as Dataconomy detailed the mechanics: current and former staff could sell a portion of their holdings to a group of institutional buyers at the $852 billion price, the same structure OpenAI has used in prior tender rounds going back to 2023.
Why a Tender, Not an IPO
Tender offers have become the release valve of choice for AI labs sitting on paper wealth they aren't ready to convert into public shares. OpenAI has now run multiple rounds of employee share sales rather than filing an S-1, even as speculation about a public listing has built for more than a year. The practical logic is straightforward: a tender offer lets staff cash out enough to cover taxes, mortgages and life expenses without forcing the company to open its books to public markets, accept quarterly earnings scrutiny, or lock in a valuation that public investors might price differently than private secondary buyers do. For a company still burning significant cash on compute and model training, avoiding that scrutiny a while longer has real value.
The Valuation Gap With Anthropic
The timing is notable because it lands just as Anthropic has pulled ahead of OpenAI on paper. Anthropic closed a $65 billion Series H round in May at a $965 billion valuation, and secondary-market pricing tracked by Nasdaq Private Market now puts the company above $1.1 trillion -- roughly $250 billion higher than OpenAI's fresh $852 billion tender mark. Both companies are still private, so neither number is a market-tested price the way a public listing would produce; they're both a function of which buyers show up to secondary auctions and what they're willing to pay that week. But the crossover is new: for most of 2025 and early 2026, OpenAI held the larger valuation of the two labs.
Numbers in Context
An $852 billion valuation on a $7 billion tender is a modest step up from OpenAI's roughly $500 billion mark from its late-2025 secondary sales, but it's well short of the trillion-dollar figures some bankers floated earlier this year for a potential 2027 listing. Set against Anthropic's $1.1 trillion secondary price and SpaceX's roughly $1.75 trillion S-1 target, OpenAI's tender price suggests private-market buyers are pricing in real uncertainty about margin and path-to-profitability that hasn't fully resolved even as revenue keeps climbing.
What Founders and LPs Should Watch
For LPs with exposure to either lab through secondary funds or fund-of-funds vehicles, the valuation crossover is a reminder that private AI marks move on sentiment and buyer appetite as much as on fundamentals -- an $852 billion tender price today says less about OpenAI's intrinsic worth than about what a specific pool of institutional buyers agreed to pay this week. Founders raising in the current environment should treat both numbers as data points on investor risk appetite for frontier AI bets, not as a fixed ceiling or floor.
The Counterweight
The risk in reading too much into the crossover is that neither valuation has been tested by public markets, and secondary pricing can be thin and easily swayed by a handful of large trades. Critics of both marks note that OpenAI and Anthropic remain unprofitable at the scale they're now valued, and a tender offer completing smoothly says more about employee demand for liquidity than about long-term enterprise value. Anthropic's higher mark could just as easily compress if its own next tender or funding round comes in below expectations.
Ahead
Neither company has set a public IPO date, and a completed tender offer, if anything, buys OpenAI more time to stay private. The next real test is whether Anthropic's $1.1 trillion secondary price holds up in its own next liquidity event, or whether the two labs' valuations converge again once one of them actually files to go public.
