Anthropic Files for IPO, Citing AI's Promise to Improve How People Live and Work

Anthropic, the company behind the Claude artificial intelligence platform, filed for an initial public offering on Monday, moving closer to a market debut that has been widely anticipated and that is expected to serve as a major test for the fast-growing AI industry.

In its S-1 filing with the Securities and Exchange Commission, the company laid out its outlook for a world deeply shaped by AI. "We believe the diffusion of AI through the global economy represents one of the largest opportunities in history to improve how humans live and work, and it is just beginning," Anthropic wrote.

The filing shows rapid financial growth. Anthropic took in $16.3 billion in revenue during the first half of 2026, compared with $1.2 billion in the same period a year earlier. The company said it expects that growth rate to decline over time. It has not yet turned a profit, reporting a net loss of $80.7 billion for the first six months of the year, more than six times the loss of nearly $13 billion in the first half of 2025.

Much of the spending went toward computing power. Anthropic put $8.9 billion into chips and other infrastructure to run its platform in the first half of 2026, up from $2.3 billion a year earlier.

Market analysts expect the offering as early as November. Reports suggest it could raise as much as $100 billion, which would surpass the record $86 billion raised by Elon Musk-owned SpaceX. Anthropic was valued at $965 billion in May, and its value could climb to $1.5 trillion or even $2 trillion, though no final valuation has been set. The shares will list on the Nasdaq under the ticker symbol "ANT."

The company's seven co-founders, including CEO Dario Amodei, addressed prospective buyers in a letter within the filing. "We encourage you, as a prospective owner of our stock, not to think of your purchase in purely transactional terms," they wrote, adding that they hoped investors would see it as a chance "to be part of something greater."

Analysts say the stakes reach well beyond one company. Nigel Green, CEO of investment firm deVere Group, called the IPO "a referendum on the entire AI trade." He said a strong debut could bring a wave of AI listings and more capital, while a stumble could quickly reset valuations across the technology sector. Analysts at advisory firm Lightshed offered a starker view: Anthropic "could become the most valuable company in the world. It could also end up in bankruptcy."

The filing also lists risks. Anthropic's growth depends on access to enough capital, including debt financing. The company also said it must use its existing AI models to design and train newer ones, a process known as recursive self-improvement. Failing to devote enough compute and research to that effort, or being outpaced by rivals who use AI better, could leave it "progressively further behind," the filing states. AI experts warn that this approach to building more powerful models raises safety risks.

Anthropic confidentially filed for an IPO with the SEC in June, ahead of a rival that filed just over a week later. Both companies are proceeding despite continuing concerns about the threats AI could pose to humanity. Amodei has said the pace of technological growth should serve as a warning sign, while arguing for continued AI development.
