WASHINGTON, September 3, 2026, 07:27 EDT — The U.S. Justice Department has lent support to OpenAI’s use of fair-use arguments in a closely watched copyright court battle, helping to clarify the legal standing of its training model. The endorsement does not resolve pending claims against the company, currently valued at $852 billion.
- The Justice Department stated that the advantages to the public from model training are greater than the potential competitive damage.
- OpenAI was last valued at $852 billion post-money, with $122 billion in committed capital.
- The disclosed monthly revenue of $2 billion suggests a valuation-to-annualized-revenue multiple of 35.5 times.
- Microsoft continues to serve as OpenAI’s main cloud partner and holds a significant share in the company.
The valuation offers limited flexibility for expensive shifts in training costs. OpenAI reported in March that monthly revenue stood at $2 billion. Projected over a year, that totals $24 billion—amounting to 2.8% of its most recent valuation.
The government’s submission does not constitute a court decision, nor does it resolve disputes about outputs or market replacement. It bolsters OpenAI’s position regarding training inputs, the core of model construction.

The department stated that the “creative possibilities and public benefits” significantly surpass any potential competitive harm. Its lawyers maintained that developing models supports economic and national-security objectives. The filing was made on Tuesday, according to AP.
The New York Times contests that view of balance. A spokesperson for the newspaper stated AI firms ought to “pay fairly for the content.” The Times filed a lawsuit in 2023, and more publishers have now joined the legal action.
The valuation hurdle
Regulation is another factor weighing on valuation. Chief Executive Sam Altman described the administration’s Astra review as a “productive process” on Wednesday. OpenAI limited certain aspects of the model after designating its cyber capability as critical. Axios interview
Microsoft Corp. NASDAQ:MSFT stands as the most direct publicly traded exposure. The company is OpenAI’s main cloud supplier and holds a significant equity stake. Microsoft’s license to use OpenAI’s technology lasts until 2032, with revenue-sharing arrangements in place until 2030.
Microsoft’s recent closes

While this shift results from various factors and cannot be directly linked to the lawsuit, it indicates that the partner’s shares opened Thursday trading below their level on the prior Friday.
The transmission has both financial and operational aspects. A wider loss on fair-use could increase licensing expenses for model developers. These higher costs might impact OpenAI’s margins, funding requirements, and Azure consumption economics.
How copyright risk reaches investors

According to Axios on Wednesday, OpenAI is at an earlier stage in its IPO journey than Anthropic. Legal clarity remains helpful for both, but isn’t the determining factor. Investors also face the task of evaluating computing requirements, oversight of models, and the quality of revenue.
Risks: The judge might disagree with the government’s position or distinguish between training and output allegations. The expense of a settlement is still unclear. Private-company revenue figures are not audited, and IPO schedule and details are subject to revision.
The upcoming court ruling, rather than the initial filing, is the next actionable signal for investors. In the meantime, OpenAI’s revenue multiple of 35.5 introduces legal uncertainty into its valuation.
