An amended SEC filing shows the Claude maker's net loss shrinking to $23.3 billion while quarterly revenue reached approximately $17 billion
Anthropic’s third-quarter net loss narrowed sharply as revenue climbed, according to an amended IPO filing with the US Securities and Exchange Commission, Reuters reported on Monday, November 2.
The AI company filed to go public only last week, and its offering could become the biggest IPO on record.
The numbers inside the amended filing
Anthropic, the developer behind the Claude models, brought in approximately $17 billion in the third quarter of 2026. That marks growth of over 1,100% year-over-year.
The net loss also improved, shrinking to $23.3 billion from $66.3 billion in the prior quarter. The filing indicates the loss stemmed mainly from non-cash accounting adjustments rather than money actually leaving the building.
The operating line tells a less flattering story. Anthropic posted a $567 million operating loss in the third quarter, a reversal from the $974 million operating profit it recorded in the second quarter. Escalating computing costs drove that swing.
Sequential revenue growth slowed to 47% in the latest quarter.
The road to a record listing
Anthropic plans to list Class A shares on the Nasdaq under the ticker ANT. The debut could potentially arrive in the week of November 16, 2026.
Early discussion around the deal points to a possible valuation between $1.5 trillion and $2 trillion, with the company potentially raising as much as $100 billion. The company has not yet disclosed share count or pricing.
Anthropic’s last private valuation was $965 billion post-money, set during a Series H funding round in May 2026. Even the low end of the discussed IPO range would sit well above that mark.
Anthropic has lined up roughly $895.4 billion in computing and infrastructure commitments running through 2033, with partners that include Amazon and Google.
