Topline
Anthropic filed paperwork for an initial public offering (IPO) before the stock market opened on Monday. The company makes Claude, an AI assistant, and is moving closer to what could become one of the biggest stock market debuts in history. The filing also revealed many previously unknown details about how the company operates and how it sees AI’s role in society.
Key Facts
Anthropic privately filed its IPO paperwork with the Securities and Exchange Commission in June. It plans to trade under the stock symbol “ANT” and could go public as early as mid-November.
The filing did not reveal the company's target valuation or how many shares it plans to sell.
The filing shows that Anthropic earned about $16.3 billion in revenue during the first half of the year, up from $1.2 billion during the same period a year earlier. However, it also reported a net loss of $80.7 billion for the first half of the year.
According to the filing, Goldman Sachs and Morgan Stanley are leading the IPO.
Technology stocks rose after the news on Monday. Nvidia shares climbed 2.4%, Microsoft rose 1.5%, Tesla gained more than 5%, Micron increased 3%, Broadcom rose 2.3% and CoreWeave gained 1.8%.
HOW ANTHROPIC THINKS AI COULD BE APPLIED WITH “INCREDIBLE POTENTIAL”
Anthropic's filing explains that the company wants investors to understand both the benefits AI could bring and the dangers it could create. It describes four main ways AI could help: improve biology and medicine, grow the economy, make important services available to more people, and improve government services. In health care, Anthropic believes AI could help cure cancer, Alzheimer's disease, heart disease, rare genetic diseases and major infectious diseases. The filing says Claude has already helped make biological discoveries, including the discovery of a molecular machine that might be used for gene editing. For the economy, Anthropic believes AI could help solve the problem of slow productivity growth in developed countries by making existing work more efficient and finding new ways to do things. It also believes AI could increase economic growth around the world and help bring medicine and services to communities that lack important health care. Better data and access to a wider range of expertise could help make this possible. Finally, Anthropic believes AI could greatly improve tax services, social services, medical services, and government planning and permit processes. The company plans to keep working with governments to make these processes more efficient. These goals are similar to ideas shared by Anthropic co-founder and CEO Dario Amodei in his major October 2024 essay, “Machines of Loving Grace.” In that essay, he wrote that five areas of AI—biology and physical health, brain science and mental health, economic development and poverty, peace and government, and work and meaning—had “the greatest potential to directly improve the quality of human life.”
WHERE ANTHROPIC THINKS AI POSES THE GREATEST RISKS
“Anything so powerful can be used for ill as well as good,” the filing says. It describes four main risks: people could use AI to cause harm, AI could act independently, authoritarian governments could misuse it, and AI could cause major economic disruption. To reduce the risk of people misusing its technology, Anthropic says it has safety rules and programs that give trusted users access to its systems while trying to prevent harmful uses. The company also warns that AI acting on its own could become “a global security threat of the first order.” Authoritarian governments could use AI to build advanced surveillance systems, increase repression and strengthen their control. Anthropic also says it will study the economic disruption AI may cause. It has already promised $200 million to work with governments on studies that could help them prepare possible responses.
CRUCIAL QUOTE
“We believe that Al is one of the most consequential technologies in human history. If managed well, it could rapidly accelerate scientific innovation, greatly increase economic growth rates, bring cures for major diseases within reach, and solve problems that have resisted generations of human effort,” the filing says. It adds, “Anthropic aims to realize these benefits while navigating and preventing the risks that come with a technological revolution this fast and this powerful.”
BIG NUMBER
Anthropic reported total liabilities of $117 billion as of June 30, 2026. However, its balance sheet does not include lease obligations until the leases officially begin. This means many of the company's large future commitments are not included in that total. As of June 30, 2026, its estimated future lease obligations that had not yet been recorded totaled $321 billion. The company listed many contracts that are due to begin later this year. Anthropic committed to spending at least $45 billion with Microsoft between November 2026 and May 2033, $114.5 billion with Google between April 2026 and July 2033, and $110 billion with Amazon between May 2026 and April 2036. It also committed to spending up to $120.5 billion with SpaceX under agreements running through 2029, up to $44.6 billion with subsidiaries fully owned by Nscale Global Holdings Limited under agreements running through 2033, and about $41 billion with Lambda, Inc. under agreements running through 2034.
ANTHROPIC’S MASSIVE CAPITAL EXPENDITURE
Since it was founded, Anthropic has spent more than $19 billion on AI infrastructure, including the computing systems and other technology needed to run AI. Its total commitments could reach about $1 trillion through 2045. That would equal about 3% of the $31.6 trillion that PwC estimates will be spent on AI development worldwide by 2050. If Anthropic cannot grow its revenue fast enough to cover its spending, its IPO and the wider technology industry could face a major slowdown.
FORBES VALUATION
According to Forbes' calculations, each of Anthropic's co-founders owns about 1.4% of the company. The shares held by Dario Amodei, Anthropic's co-founder and CEO, are estimated to be worth $13.6 billion. Daniela Amodei, his co-founder and the company's president, has a stake estimated at $13.7 billion. Dario Amodei's estimated net worth was $15.5 billion on Monday, placing him at No. 178 on Forbes' Real-Time Billionaires list. He was tied with Daniela Amodei. Jack Clark, Anthropic's head of public benefit, and Jared Kaplan, its chief science officer, each have stakes estimated at $13.7 billion. Anthropic has not disclosed the valuation it is seeking. However, if the company is worth between $1.5 trillion and $2 trillion, as some estimates suggest, each co-founder's net worth would exceed $20 billion, according to Forbes' calculations.
KEY BACKGROUND
A group of former OpenAI employees founded Anthropic in 2021. The company created Claude, a group of AI models that compete with products such as OpenAI's ChatGPT and Google's Gemini. Amazon, Google and Nvidia have invested billions of dollars in Anthropic. These investments help fund spending on computer chips, data centers and other work needed to develop and sell AI technology. Anthropic reported its third-quarter earnings in October, showing that quarterly revenue had grown 45% to $16.8 billion. The company has committed to spending $518 billion over ten years on cloud services, computing and infrastructure. In the first half of the year, it reported spending nearly $9 billion on computing capacity and infrastructure, compared with $2.3 billion during the same period a year earlier.
TANGENT
Anthropic's IPO comes as investors become more concerned about whether the large amounts of money being spent on AI will produce enough returns. The latest worries followed earnings reports from Meta and Tesla. Their reports showed high and low capital spending, respectively, and helped trigger the latest drop in AI-related stocks on Thursday. These concerns, along with rising interest rates, are creating difficult conditions for many technology and semiconductor companies. They have also influenced other AI companies, including Switch and Nscale, to delay their IPOs until later this year. Reuters reported this, citing people familiar with the matter.
SURPRISING FACT
Anthropic is committing at least 5% of its shares to a new public benefit fund after it goes public. The Anthropic Public Benefit Fund must be approved by shareholders. It is intended to give the company more “flexibility and scale” in making donations to nonprofit groups or providing money directly to certain groups of people. The fund will not support political donations or lobbying. Hours after Anthropic announced the plan, Elon Musk said that he would give every child in America one SpaceX share next year.
