On August 30, 2024, TechCrunch reported that some secondary-market indications put OpenAI’s valuation above $100 billion: Rainmaker Securities had seen bids implying up to $143 billion, while data platform Caplight estimated more than $111 billion. Those figures were a reported bid ceiling and an analytical estimate—not a public share price or a valuation OpenAI had just secured in a funding round.
What did the 2024 headline mean?
The headline referred to a TechCrunch report published August 30, 2024. It described interest in OpenAI shares changing hands between investors, rather than a new investment made directly into OpenAI.
| Date and source | Reported figure | What it represents | Did OpenAI raise new capital? |
|---|---|---|---|
| August 30, 2024; Rainmaker Securities, as reported by TechCrunch | Up to $143 billion | Bid indications Rainmaker said it had seen; not a completed company financing or public-market quotation. | No; bids concerned shares held by existing investors. |
| August 30, 2024; Caplight, as reported by TechCrunch | More than $111 billion | Platform estimate based on secondary activity and previous traditional financing rounds. | No; this was an estimate, not a direct investment into OpenAI. |
| March 31, 2026; TechCrunch | $122 billion raised at an $852 billion valuation | Reported primary funding round, in which the company raised capital. | Yes. |
| August 10, 2026; TechCrunch; funding structure described by Dealroom | $7 billion employee tender at an $852 billion valuation | Employee liquidity transaction reported at the same valuation as the March round; Dealroom says OpenAI funded the buyback and no outside buyers participated. | No new outside capital, according to Dealroom’s account. |
These figures are not points in one clean price series. A bid indicates what a prospective buyer may offer; an estimate combines inputs according to a platform’s method; a primary-round valuation is negotiated in a company financing; and a tender price applies to a specific liquidity transaction. The last two can differ in who supplies the money and whether the company receives new capital.
How secondary-market transactions differ from funding rounds
In a secondary transaction, an investor buys shares from an existing shareholder. The company is not necessarily issuing new shares or receiving the purchase money. In a primary financing, investors buy newly issued securities from the company, which raises capital. A private company’s shares do not trade on a public exchange, so bids and private transactions can be limited, negotiated, and conditional rather than continuously quoted.
#1 Best Overall
That is why “OpenAI was valued at $143 billion” would overstate what the 2024 report established. Rainmaker described bids implying a valuation up to that level; the report did not say that a company-wide transaction closed at that price. Caplight’s figure was an estimate, not a direct observation of one completed deal.
How the later $852 billion figures compare
March 2026: a primary financing
TechCrunch reported on March 31, 2026, that OpenAI closed a $122 billion funding round at an $852 billion valuation. It named SoftBank, Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, T. Rowe Price Associates, Amazon, Nvidia, and Microsoft among participants. This was a company financing and should be distinguished from the 2024 bids and estimate.
Rank #2
August 2026: an employee tender funded by the company
TechCrunch reported an employee tender worth $7 billion at the same $852 billion valuation. Dealroom’s account says OpenAI used its own cash to fund the buyback and outside buyers did not participate. It is therefore more precise to describe it as an employee tender or company-funded buyback, not as a fresh external secondary-market price discovery event.
What the figures do—and do not—tell investors
Private-company valuation figures are tied to their date, source, and transaction structure. Even when two figures use the word “valuation,” they may reflect different evidence and circumstances. When comparing them, check:
- What kind of figure is it? A bid, an estimate, a primary-round valuation, or a tender price.
- Was there a completed transaction? A reported bid is not proof a deal closed at that implied value.
- Who bought the shares? An external buyer, the company itself, or a new investor in a primary round.
- Did the company receive capital? Secondary sales to existing shareholders generally transfer ownership; a primary round raises money for the company.
- When was it reported? A private-market indication from 2024 is not a live price in 2026.
Forge’s August 2026 private-market update, using data as of July 31, 2026, lists OpenAI as taking 8.3 years to reach a $100 billion valuation. That is a Forge dataset statistic, not an official company measure or a universal calculation. Forge also describes tenders and secondary transactions as ways private-market participants seek more frequent price discovery.
Was a $100 billion valuation “rich”?
In the August 2024 TechCrunch report, Rainmaker Securities co-founder and managing partner Glen Anderson said there was substantial investor interest. He offered a personal, conditional judgment: “So a $100 billion valuation, is it rich? Maybe. But, I mean, if OpenAI can live up to [its] potential, it may be a steal.” That was Anderson’s opinion about potential and price, not an objective finding that the valuation was cheap or fair.
Rainmaker co-founder and managing director Greg Martin likewise told TechCrunch that it was hard to put a proper valuation on OpenAI, while saying demand was strong. Demand alone does not establish what a buyer ultimately paid or what the shares would be worth in another transaction.

The cited reporting establishes the 2024 bids and estimate, the March 2026 primary round, and the August 2026 company-funded tender. It does not establish a live October 2026 external secondary-market price. Treat the $852 billion figures as valuations reported for those specific events, not as a guaranteed current price at which an outside investor can buy or sell shares.
