Artificial intelligence giant Anthropic has confidentially filed for an initial public offering (IPO) in the United States, signaling a potential landmark event for Wall Street's intense focus on artificial intelligence.

The move, announced on Monday, represents a critical evaluation of whether investor enthusiasm for the AI revolution, which has significantly altered white-collar work globally, can sustain the high expectations surrounding the rapidly expanding sector.

Anthropic, the company behind the AI chatbot Claude, did not reveal the size or specific terms of the offering. Confidential filings allow companies to progress with IPO preparations while keeping crucial financial data shielded from competitors and the public.

This significant step toward a public listing follows SpaceX's substantial IPO, which is poised to set new records with its potential $75 billion offering at a $1.75 trillion valuation. Both Anthropic and SpaceX, alongside rival OpenAI, are expected to eventually become publicly traded companies, though all three are currently operating at a loss, raising concerns about a potential AI market bubble.

Anthropic, established in 2021 by former OpenAI executives, has become a prominent face of the AI boom. This surge has reshaped corporate strategies, fueled a global competition for computing power and talent, and propelled AI-related companies to become some of the most highly valued firms in the market.

The company reported in late May that it had secured $65 billion in its latest funding round, achieving a post-money valuation of $965 billion, surpassing its rival OpenAI. At that time, Anthropic also stated it was generating $47 billion in annualized revenue from selling its technology to individuals and organizations utilizing Claude for various work and personal tasks, including coding.

Anthropic's rapid ascent in early 2026 caused market jitters, leading to significant sell-offs in software and IT stocks. Investors expressed concerns that the company's increasingly autonomous AI tools could disrupt established business models and accelerate industry-wide changes.

"OpenAI and Anthropic are in a race to go public before capital runs out," noted analyst Gil Luria from investment firm DA Davidson. He also suggested that Anthropic's motivation to precede OpenAI in the public market might stem from a desire to "set the agenda for how a frontier model reports financials and do so in a way that is favourable to their financial model."
