“vs prior closed” = post-money ÷ the prior closed round’s post-money. OpenAI has not stated a run-rate in any round announcement, so no multiples are shown. Rounds before October 2024 are not yet in this tracker.

Methodology & status definitions

How each row is labelled and calculated.

Closed round

A round OpenAI has announced as closed, with the post-money valuation it stated. Only these rows appear in the chart.

Reported talks

Figures reported by the press while a round was being negotiated or before OpenAI announced it, attributed to the outlet. The November 2026 rows describe money reported as raised in a round OpenAI has not announced; they stay here until it does. Talks figures are not valuations.

Tender

A sale of existing employee shares to investors. Amounts and prices are as reported by CNBC. A tender valuation is the price the sale was set at, not a new primary round, so it is not plotted and carries no multiple.

Valuation ÷ run-rate

Post-money ÷ the run-rate revenue the company stated in that round’s announcement (GNF calc.). None of OpenAI’s round announcements state a run-rate. The March 2026 announcement gives monthly revenue (“$2B in revenue per month”); GNF does not annualise it, so no multiple is shown. Run-rates reported by the press from unnamed sources are not used.

What is not a separate row

Debt and credit facilities (the revolving facility expanded to about $4.7B in March 2026). Microsoft’s earlier investments, and the 2024 round’s predecessors, are not yet in this tracker. A reported October 2025 Reuters story on IPO groundwork is omitted because GNF could not open the article to verify it.
