Anthropic, the U.S. company behind the Claude artificial intelligence model, has begun the process of going public by submitting its public offering documents to the U.S. Securities and Exchange Commission (SEC). According to reports, the filing means the company's shares could start trading before the U.S. Thanksgiving holiday, which this year falls on November 26.
Context in the wave of AI-related listings
Several AI-focused companies prepared for public listings over the summer. In June, SpaceX opened the sequence with a record-sized initial public offering, and both OpenAI and Anthropic filed paperwork for listings earlier in the summer. Bloomberg estimated that those three companies together could add roughly $3,600 billion to U.S. stock exchanges.
Investor expectations and market risks
Anthropic's IPO is arriving amid heightened expectations, but investor views on valuation vary: some investors currently value the company at about $1,500 billion. The success of the offering could influence sentiment across the entire AI market, especially as OpenAI is also a candidate for a public listing next year.
Investors are increasingly focused on whether technology firms can generate adequate returns on the hundreds of billions invested in chips and data centers.
Financials: a large accounting loss and rising infrastructure spending
Anthropic reported a first‑half loss of $80.7 billion, up from $13 billion a year earlier. The filing clarifies that most of the increase was not from operating expenses but from a single accounting item: approximately $72 billion of the loss resulted from the revaluation of convertible notes the company had issued. As Anthropic's estimated market value rose, the book value of those convertible instruments increased, producing a reported loss.
Operational spending has also risen sharply: compute capacity and infrastructure expenditures jumped from $2.3 billion in the first half of last year to nearly $9 billion in the first half of this year.
Why this matters
Anthropic's public offering could be a significant milestone for AI companies on public markets. Beyond adding to overall market capitalization, the IPO will be watched as a test of investor appetite for AI firms that must deploy massive capital into infrastructure. The market will be monitoring the valuation, the terms of the offering, and how the listing affects sentiment across the AI sector.
