Key takeaways
- Anthropic files publicly for Nasdaq listing under ANT
- First-half revenue surges to $16.3 billion
- Noncash accounting charges dominate $80.7 billion net loss
Anthropic, the artificial intelligence company behind Claude, publicly filed for an initial public offering on October 26, revealing an extraordinary $80.7 billion net loss during the first six months of 2026 despite rapidly growing revenue.
The company plans to list on the Nasdaq Global Select Market under the ticker ANT, according to its official IPO announcement.
However, most of the headline loss resulted from accounting adjustments rather than cash spent developing AI models, raising an important question for investors preparing to value one of the world's largest AI startups.
Anthropic Reports $80.7 Billion Loss as Revenue Surges
Anthropic generated $16.3 billion in revenue during the six months ended June 30, compared with approximately $1.2 billion during the same period in 2025.
That represents more than thirteenfold year-over-year growth, reflecting increasing demand for Claude and the company's enterprise AI products.
Yet its reported net loss reached $80.7 billion, compared with $13 billion a year earlier.
Approximately $72.4 billion of that amount came from changes in the fair value of convertible notes and related financial instruments, largely reflecting Anthropic's rising private-market valuation.
These were primarily noncash accounting charges, meaning they did not represent $72.4 billion in payments to employees, suppliers or data-center operators.
The company's actual operating loss was approximately $693 million, according to financial details in its registration documents.
That distinction matters because Anthropic previously reported an operating loss exceeding $8 billion in 2025, when infrastructure costs exceeded annual revenue.
Nevertheless, computing and infrastructure expenses approached $9 billion during the first half of 2026, demonstrating the substantial cost of operating frontier AI systems
ANT Stock IPO Could Test a $1.5 Trillion Valuation
Anthropic's public filing represents a major step beyond the confidential IPO application submitted earlier this year.
The company has not disclosed how many shares it will sell or established an official offering price.
Goldman Sachs and Morgan Stanley are leading the proposed offering, while reports suggest trading could begin in November.
Some investors have considered valuations between $1.5 trillion and $1.75 trillion, below earlier expectations approaching $2 trillion.
Coinpaper previously examined how Anthropic's potential valuation reduction could reflect growing scrutiny of AI infrastructure spending.
The company's private valuation reached approximately $965 billion in May, meaning even a $1.5 trillion public valuation would represent a substantial premium.
Can Anthropic's Revenue Growth Justify Its AI Spending?
Anthropic's listing comes as investors increasingly question whether rapid AI adoption can produce sustainable profits.
The Claude developer previously reported third-quarter revenue of $16.8 billion, highlighting continued expansion but also enormous infrastructure requirements.
Its growth has attracted attention from semiconductor suppliers, including Nvidia, which reportedly considered participating in Anthropic's offering.
The company has also disclosed substantial long-term commitments for cloud services and computing infrastructure.
Coinpaper previously compared Anthropic's potential debut with SpaceX's record-setting IPO, which demonstrated both enormous investor appetite and the risks of ambitious public valuations.
