OpenAI’s quarterly revenue increased approximately 50% to $10 billion in the third quarter of 2026, but the company continued to report substantial operating losses, highlighting the financial challenges associated with expanding its artificial intelligence business.
According to a report by The Wall Street Journal, which cited documents shared with investors, the ChatGPT developer’s operating losses widened to $10.9 billion in the July–September quarter, compared with $10.1 billion in the previous quarter.
The results reflect strong commercial growth alongside significant spending requirements as OpenAI continues investing in AI development, computing infrastructure and its expanding range of products and services.
Revenue Growth Fails to Translate into Lower Overall Losses
OpenAI’s revenue growth of approximately 50% between the second and third quarters demonstrates increasing demand for its AI products and services.
However, its operating losses increased by $800 million during the same period, indicating that the company continues to face substantial costs despite generating higher sales.
The company’s adjusted operating margin improved to negative 109% in the third quarter, compared with negative 150% in the previous quarter, according to the documents reviewed by the Journal.
The improvement suggests that revenue grew faster than the costs reflected in the adjusted margin calculation. Nevertheless, the widening operating loss shows that OpenAI remains far from achieving profitability.
OpenAI did not immediately respond to a Reuters request for comment.
Competition with Anthropic Intensifies
The financial disclosure comes as competition between leading artificial intelligence companies intensifies, particularly between OpenAI and its rival Anthropic, the developer of Claude.
Anthropic reported third-quarter revenue of $17 billion, compared with OpenAI’s $10 billion, according to figures cited in the Journal’s report.
Anthropic also reported an operating loss of $567 million for the period, significantly below OpenAI’s reported figure. However, the financial measures used by the two companies may not be directly comparable.
The contrast highlights the growing importance of revenue generation and financial sustainability as AI companies compete for enterprise customers, investment and market share.
Anthropic’s planned initial public offering has also brought greater attention to the financial performance of major AI businesses, with investors closely examining their revenue growth, operating costs and long-term profitability prospects.
Heavy Investment Requirements Continue to Challenge AI Companies
The development and operation of advanced AI systems require substantial computing resources, specialised hardware, data infrastructure and technical talent.
As companies expand their AI models and services, the costs associated with training and running these systems remain a major financial consideration.
OpenAI’s latest results underline the challenge of converting rapid adoption into sustainable earnings. Although its revenue has increased considerably, its operating losses indicate that expenditure continues to outpace the income generated by its business.
The company is also competing in an increasingly crowded market, where rivals are expanding their enterprise offerings and investing in advanced AI capabilities.
Investors Closely Monitor Long-Term Financial Sustainability
The latest figures arrive at a time when investors are increasingly scrutinising the economics of the artificial intelligence industry.
The sector has attracted significant capital on expectations that AI applications will transform business operations, productivity and consumer technology. However, the scale of infrastructure investment required has raised questions about how quickly leading companies can turn growth into profits.
OpenAI’s third-quarter performance presents a mixed picture: revenue has reached a new milestone, and its adjusted operating margin has improved, but its overall operating losses have continued to widen.
The company’s ability to maintain revenue growth while controlling infrastructure and operating expenses will remain central to its long-term financial outlook.
As competition with Anthropic and other AI developers intensifies, OpenAI faces the challenge of demonstrating that its growing commercial reach can eventually translate into a sustainable and profitable business model.
