OpenAI in Talks for Funding Round Valuing It at Over $100 Billion

OpenAI was discussing financing on August 28, 2024 that would value the company above $100 billion. The original Wall Street Journal report attributed the information to people familiar with the talks, placed Thrive Capital in the lead with about $1 billion and said Microsoft was expected to contribute.

There was no closing announcement from OpenAI, Thrive or Microsoft that day. “In talks” was the accurate description: a round can change size, price, participants and terms, or fail to close. The headline offers a durable lesson in reading private-company valuations without confusing an investor proposal with cash received, a public share price or an exact value for every shareholder.

The source is part of the data

The news came from original reporting based on sources who were not publicly identified, not a company release. The Journal page makes the headline, authors, summary and opening paragraphs visible, while the full text requires a subscription. That limit matters: the central claim and attribution can be checked, but an outside reader cannot inspect every detail supporting the exclusive.

Every element therefore keeps its degree of certainty. “OpenAI closed a round” would have been false on August 28. “Microsoft invested” would have anticipated a decision. “People familiar with the matter told the Journal that Microsoft was expected to participate” distinguishes negotiation from completion. Anonymous sourcing can produce legitimate information; it does not become corporate confirmation.

The first question attached to a financial number is which document supports it: a release, filing, audited account, contract or journalistic report. The second is which verb it uses. Exploring, negotiating, committing and closing are different milestones. Skipping that ladder converts expectations into balance-sheet facts.

Valuation is not cash in the bank

A valuation is a relationship between the agreed price of one capital unit and the set of units being counted. If an investor pays $50 for a new share and the company has two billion share equivalents after the transaction, the post-money valuation would be $100 billion. It does not mean anyone deposited $100 billion.

The difference between pre-money and post-money prevents another error. In a hypothetical $5 billion round at a $100 billion post-money valuation, the value before the cash is $95 billion and the new securities represent about 5% after the deal. If $100 billion were the pre-money figure, the result after financing would be $105 billion and the percentage would differ.

Public information on August 28 described several billion dollars and a value above $100 billion, but did not expose a complete contract resolving that convention. A careful reader does not fill the gap. They look for whether the figure is before or after the capital and keep the ambiguity visible when the source does not say.

Nor is this market capitalisation. The SEC defines market capitalisation for a public company as outstanding shares multiplied by an observable market price. OpenAI was private: no continuous exchange auction revalued every interest each minute.

Not every share has the same value

Venture rounds commonly issue preferred stock. The SEC glossary says it may carry liquidation priority, anti-dilution protection, rights to maintain ownership, dividends or votes on important decisions. An employee’s common share may lack those protections.

Multiplying the latest preferred price by every share therefore creates a headline valuation, not necessarily the cash each owner would receive in a sale. In a poor outcome, a preference may protect the new investor first. In an excellent one, conversion rights, caps and classes determine how proceeds are divided.

The capitalisation table, or cap table, records owners, classes, quantities, prices, options, convertible notes and other rights. Interpreting a round requires at least five columns: instrument, price, security count, preferences and fully diluted percentage. The large number without that table is a price signal, not a complete account of ownership.

Dilution does not necessarily mean existing owners lose economic value. Their percentage falls when new securities are issued, but the company receives resources that could make the remaining percentage more valuable. The question is what the company receives in exchange, at what price and under which obligations.

Primary round versus secondary sale

A primary transaction creates securities or instruments and sends money to the company. A secondary lets employees or existing investors sell their holdings; the money mainly goes to the seller. Both can set a valuation reference, but only the first directly finances data centres, research, payroll or commercial expansion.

The Journal compared the talks with an earlier OpenAI reference near $86 billion. A useful comparison asks whether both transactions had the same nature and rights. A tender for existing common shares and a new preferred round can use similar prices while sending cash to entirely different places.

Private interests are also illiquid. The Investor.gov bulletin on private placements warns of resale restrictions, limited public information and difficulty determining whether a price is fair. A small block traded among sophisticated parties does not prove the whole company could be sold tomorrow at the same multiple.

What Microsoft’s presence revealed

Microsoft was not merely a prospective financier. In January 2023 it officially described the third phase of the relationship as a multiyear, multibillion-dollar investment alongside Azure supercomputing, model commercialisation and cloud use. The release did not provide the $13 billion figure repeated in much coverage, so that number should not be presented as company-confirmed.

A strategic partner may supply capital, compute, distribution and customers while also selling services and buying products. Those roles create interdependence. Analysing its participation requires separating new cash, services sold, rights received and any consumption or revenue-sharing commitments. The label “investor” does not describe the whole economic circuit.

The value placed on a model company measures more than demand for ChatGPT. It packages expectations about future products, training and inference costs, chip availability, energy, competition and regulation. A high valuation is a price accepted by some investors under specified terms; it does not certify that their expectations will be met.

OpenAI’s structure added another layer

OpenAI had explained in 2019 that its capped-profit partnership was controlled by the nonprofit and that economic returns for investors and employees had negotiated limits. The official OpenAI LP description also said the mission obligation could take precedence over financial interests.

That makes a conventional valuation especially incomplete. A reader would need to know which entity issues the interest, which economic right each investor buys, which limits apply and who retains control. “OpenAI is worth X” compresses a legal architecture and several contracts into a convenient sentence.

The structure does not make price irrelevant. A round determines dilution, incentives and resources and can raise the reference for employees and investors. What changes is the inference: the price of a conditional interest does not automatically turn the entire organisation into a homogeneous $100 billion asset.

The six-question worksheet

For the next mega-round, readers can complete a worksheet: is it being discussed or closed; how much capital is raised; is the valuation pre- or post-money; is the transaction primary, secondary or mixed; which security and preferences are issued; and which source and document support it? Missing answers are marked “not disclosed” instead of guessed.

Next come the use of proceeds and each investor’s role. Capital may finance growth, cover losses, buy compute or provide employee liquidity. The same numerical headline can conceal different economics. Readers should also seek financial statements and risks, which a private company does not disclose as often as a listed one.

The transferable skill is to break a valuation into price, security count, timing, instrument and source. Applied to August 28, 2024, it requires saying OpenAI was discussing a round reported by the Journal, not that it had already received the money. Applied a year later, it will still prevent the same mistake: treating the headline’s largest number as cash, market and certainty at once.
