Anthropic, one of the world's most valuable artificial intelligence companies, has formally moved toward the public markets. The company said it filed confidential paperwork with the US Securities and Exchange Commission (SEC) to hold an initial public offering, joining a wave of technology companies that could make the coming period a landmark stretch for Wall Street listings.

Confidential IPO filings, made under the Jumpstart Our Business Startups (JOBS) Act, allow companies to submit draft registration statements to the SEC while keeping the details hidden from the public and competitors. This process has become increasingly popular for late-stage startups and high-growth technology firms because it gives them flexibility to test the market without immediate disclosure pressure. For Anthropic, the filing does not reveal the number of shares to be sold, the expected price range, or the proposed exchange. Those details are likely to emerge if the company accelerates toward a formal public offering.

The move comes at a time of intense investor enthusiasm for AI infrastructure and applications. Aerospace firm SpaceX, which holds a virtual monopoly on space launches in the US, has also filed for what is expected to be a record-breaking IPO. Meanwhile, Anthropic's main competitor OpenAI is reportedly preparing an offering of its own later in 2026. The prospect of multiple multibillion-dollar technology debuts has fueled speculation about a new era of public listings, particularly in sectors tied to artificial intelligence, cloud computing, and advanced hardware.

Key Facts at a Glance

• Anthropic has filed confidentially with the SEC for an IPO.
• The company was founded in 2021 and has grown rapidly.
• Claude Opus 4.5 and Claude Mythos models have driven recent adoption.
• Revenue is reportedly on track to more than double in the June quarter.
• Anthropic is paying $1.25bn per month for SpaceX data center capacity.
• The company's most recent private valuation stands at $965bn, ahead of OpenAI's $852bn.
• Gartner estimates it could take two to five years before AI models become productive in everyday business tasks.

From 2021 Startup to AI Powerhouse

Anthropic was founded only in 2021, making its IPO filing unusually quick by traditional standards. The company was created with an explicit focus on AI safety and reliability. From the outset, its founders argued that advanced AI systems needed to be built with careful safeguards to avoid harmful outcomes. That positioning helped Anthropic attract long-term investors who wanted exposure to AI without the risk profile associated with some other companies.

For its first few years, Anthropic operated largely as a research organization. It released a series of models under the Claude name, each iteration improving on the previous one in reasoning, coding, and safety. The company's relatively narrow focus on tools for programmers and businesses, rather than consumer chatbots, allowed it to build a strong niche in the enterprise market. Software developers began using Claude for tasks such as code generation, code review, automated testing, and security auditing. This specialization helped differentiate Anthropic in an increasingly crowded field.

Revenue Surge and Model Momentum

The business accelerated sharply in late 2024 and throughout 2025. Anthropic's Claude Opus 4.5 model, released in the autumn, began to gain significant popularity among coders. Its ability to handle complex programming tasks, explain code, and flag potential vulnerabilities made it a preferred assistant for many software engineering teams. Adoption spread through word of mouth and through direct enterprise deals, leading to a surge in API usage and subscription revenue.

More recently, the company drew widespread attention after claiming that its Claude Mythos model was significantly more capable than other tools at finding security flaws in computer systems. Anthropic said it worked with banks and governments to help secure their systems before the model's release. This security-focused positioning has become an increasingly important part of the company's pitch. By framing Claude Mythos as a defensive tool that could identify weak points before malicious actors could exploit them, Anthropic tapped into growing demand for AI-enhanced cybersecurity.

Financial results have reflected this momentum. According to financial press reports, surging revenue may see Anthropic record its first profitable quarter during the period ended in June. Income for that quarter was on track to more than double over the previous quarter, a sign of how quickly demand for advanced AI models is translating into actual dollars. However, the company reportedly does not expect to maintain profitability in future quarters. Anthropic is deliberately ramping up spending on compute infrastructure, data centers, and model training. Profitability is likely to fluctuate as it invests aggressively to compete with OpenAI, Google, and other large AI labs.

Massive Compute Spending and Valuation Milestones

Anthropic's spending commitments have grown to extraordinary levels. The company recently struck a deal with SpaceX to use capacity at its Colossus 1 and Colossus 2 data centers. According to reporting, Anthropic is paying $1.25 billion (£930 million) per month for that capacity. The arrangement underscores the extent to which AI companies now depend on massive computing clusters to train and deploy models. Data center costs have become one of the largest line items for leading AI firms, often exceeding personnel expenses and research budgets.

The scale of this spending is noteworthy because neither SpaceX nor OpenAI is profitable. Yet investors have been willing to value these companies on future potential rather than current earnings. Anthropic's most recent funding round valued the company at $965bn, surpassing OpenAI for the first time. OpenAI was most recently valued at $852bn. These valuations are extraordinary for companies that have existed for only a few years and that face ongoing questions about the long-term economics of AI.

Investor Enthusiasm and Analyst Caution

Investor enthusiasm for AI has been a defining theme in recent markets. Startups backed by major technology companies have been able to raise enormous sums without demonstrating sustained profitability. The logic is that generative AI will transform software, healthcare, finance, and many other industries, creating companies as large as the biggest technology conglomerates. Proponents point to the rapid adoption of tools like Claude by businesses as evidence that the transformation is already underway.

But industry analysts warn that the technology has not yet progressed to the stage of being useful for day-to-day tasks for the broader population. While specialized applications such as code completion and vulnerability scanning are valuable, many consumer and enterprise use cases remain experimental. Gartner estimates it could be two to five years before technologies such as foundational models or AI agents become productive in everyday business operations. The gap between current capabilities and the vision of autonomous, reliable AI systems remains a central risk for investors.

For Anthropic, the road to a public listing will test whether the company can convince traditional public investors that its growth is durable. The confidential filing gives it time to prepare while the market environment remains favorable. It also sets up a potential head-to-head comparison with OpenAI and SpaceX in what could be one of the busiest years for IPOs in US history. Whether Anthropic ultimately completes the offering this year or waits for better conditions, the move marks a major milestone for a company that did not exist before 2021.
