OpenAI reports steep losses despite quarterly revenue rise

Published on 11 November 2026 - 9:11 GMT+1

According to documents viewed by The Wall Street Journal, OpenAI told investors that its adjusted operating margin improved to -109% from -150% in the previous quarter.

The company's operating losses, however, widened to $10.9 billion (€9.72bn) from $10.1 billion (€9.01bn), the WSJ reported on Tuesday.

The disclosure comes as investors closely scrutinise the finances of AI companies, including rival Anthropic, which is preparing for an IPO that could value it at around $1.4 trillion (€1.25trn).

The stock market debut will be the first by one of the leading AI model developers and is being seen as a gauge of how long the AI spending boom lifting the US economy can last.

The maker of the Claude AI models said in a filing with the US Securities and Exchange Commission that it aims to sell 825 million shares at between $70 and $78 each (€62.44–€69.58). The shares will trade under the ticker "ANT."

Seven tech companies including Google, Nvidia, AMD and Microsoft have also agreed to buy $26 billion (€23.2bn) of non-voting shares at the IPO price in a separate private placement, the filing showed.

The companies are investors in Anthropic or major suppliers of its computing power.
