Anthropic, maker of the Claude artificial intelligence platform, filed for an initial public offering on Monday, bringing the company a step closer to going public and providing a test of investor demand for the rapidly expanding AI sector. The company said in its Securities and Exchange Commission filing that it believes artificial intelligence diffusion through the global economy represents one of the largest opportunities in history to improve how humans live and work. Market analysts expect the IPO to happen as early as November.
The filing reveals extraordinary growth in Anthropic's revenue, which reached $16.3 billion in the first half of 2026, compared with $1.2 billion for the same period in 2025. However, the company is not yet profitable. Anthropic reported a net loss of $80.7 billion for the first half of 2026, more than six times its net loss of nearly $13 billion in the first two quarters of 2025. The company spent $8.9 billion in the first half of 2026 on chips and infrastructure to power its platform, up from $2.3 billion in the same period last year.
The offering could raise as much as $100 billion and instantly rank Anthropic among the world's largest publicly traded companies, surpassing SpaceX, which raised a record $86 billion when it went public in June. Anthropic was valued at $965 billion in May, and analysts suggest its value could reach $1.5 trillion or possibly $2 trillion, though final valuation has not been established. The company's shares will list on the Nasdaq Composite Index under the ticker symbol ANT. Investment advisory firm Lightshed noted that while Anthropic could become the most valuable company in the world, it could also end up in bankruptcy.
Anthropic's filing identifies significant risks to its growth, including the need for continued access to capital and debt financing to compete with rivals. The company said it must use existing AI models to design and train next-generation platforms through a process called recursive self-improvement, warning that failure to do so could cause it to fall behind competitors. Separately, AI experts have warned that using AI to build increasingly powerful models raises the risk of losing control of the technology, potentially leading to cyberattacks or pandemics.
The company is proceeding with its public offering despite safety concerns about AI development. Anthropic CEO Dario Amodei called for a slowdown in AI development after one of his company's former researchers said there is a 10 percent chance the technology could wipe out humanity in the next decade. In an interview, Amodei said the pace of technological growth should serve as a warning sign, while making a case for continued AI development.
For US investors and savers, Anthropic's IPO outcome will signal whether the market believes AI companies can eventually turn massive capital spending into sustained profits.
