Anthropic filed for an initial public offering on Monday, bringing the maker of artificial intelligence platform Claude one step closer to its highly anticipated public market debut and providing a key test for the rapidly emerging AI sector.
In the filing, Anthropic outlined its vision for a future deeply shaped by AI, and the technology’s potential to transform the global economy and improve life worldwide.
“We believe the diffusion of AI throughout the global economy represents one of the greatest opportunities in history to improve how people live and work, and it’s just beginning,” the company said in its S-1 filing with the Securities and Exchange Commission.
The filing highlights Anthropic’s rapid growth, with the company generating $16.3 billion in revenue in the first half of 2026, up from $1.2 billion in the same period last year. That breakneck rate of expansion is likely to be slow, with Anthropic noting that its revenue growth will slow over time.
The company has yet to make a profit. Anthropic reported a net loss of $80.7 billion for the first half of the year, more than six times the net loss of nearly $13 billion for the first two quarters in 2025.
Anthropic’s founders, including Anthropic CEO Dario Amodei, pitched the IPO to investors in part as an opportunity to be part of a history-defining moment.
“We encourage you, as a potential owner of our stock, not to think about your purchase in purely transactional terms,” the company’s seven co-founders said in a letter included in the S-1. “We hope you’ll see it instead as an opportunity to be part of something bigger. The emergence of machine intelligence is one of the seminal moments in human history.”
Referendum on AI
The IPO, which market analysts expect as early as November, could immediately rank Anthropic among the world’s largest publicly traded companies. The offer could raise as much as $100 billion, according to reports. That would slingshot it past Elon Musk-owned SpaceX, which raised a record $86 billion as of went public in June.
Anthropic, which was valued at $965 billion in May, could see its value rise to $1.5 trillion or possibly $2 trillion, although its final valuation has not been established.
Anthropic shares will list on the tech-heavy Nasdaq Composite Index, according to the company’s filing. The AI company will trade under the ticker symbol “ANT”.
More broadly, the transaction will measure the strength of investor demand not only for Anthropic shares, but also for the expanding constellation of data center builders, chipmakers and other companies involved in the development of critical infrastructure AI services.
“This IPO is a referendum on the entire AI trade,” Nigel Green, CEO of investment firm deVere Group, said in an email. “If it rises, expect a queue of AI listings and even more capital pouring into the issue. If it stumbles, valuations on tech can reset quickly.”
The flood of capital flowing into AI has helped lift the stock market to record highs. The question is whether AI can maintain its momentum amid signs that investors are worried about when — and if — their money will eventually pay off and deliver the returns they’re banking on.
Anthropic’s prospectus shows that the company has invested massive amounts of money to build the computing resources needed to develop its AI models. The company spent $8.9 billion on chips and other infrastructure to run its platform in the first half of the year, compared to $2.3 billion in the same period last year.
“Anthropic could become the most valuable company in the world. It could also end up in bankruptcy,” analysts with Lightshed, an investment advisory firm, said in a research note ahead of the IPO filing.
Potential obstacles to growth
Anthropic’s IPO filing also describes several risks that could hinder its growth or cause it to fall behind competitors. Much of the company’s future growth will depend on whether it has access to sufficient capital, including debt financing, which more companies are using to finance the AI build-out.
To maintain its competitive edge, Anthropic also said it must use its existing AI models to design and train next-generation platforms, a process known as “recursive self-improvement,” or RSI.
“If we do not direct sufficient computing and research efforts to AI-assisted development, or if our competitors leverage AI more effectively to improve their own innovation cycles, we risk falling progressively further behind…” Anthropic said in the filing.
AI experts warn that using AI to build increasingly powerful border models increases the risk of people losing control of technologylikely to lead to disasters such as deadly pandemics or cyber attacks that cut off the internet, electricity or water.
Barreling ahead despite safety concerns
Anthropic filed for a confidential IPO with the Securities and Exchange Commission in June Rival OpenAI, which was submitted just over a week later. Both companies are pushing ahead with plans to go public despite concerns about the potential threats AI poses to humanity.
Reports of AI agents going rogue continue to mount, fueling concerns that the technology could escape human control and Conduct cyber attacks. In September, Amodei for one Slowing down of AI development according to one of his companies former researchers said that there is a 10% chance that technology could wipe out humanity in the next decade.
And and Interview with CBS NewsAmodei said the pace of technological growth should serve as a warning sign while making a case for further development of AI.
