Anthropic has taken a significant step toward entering the public markets, confirming that it has filed confidential paperwork with the U.S. Securities and Exchange Commission for an initial public offering. The move positions the artificial intelligence company among a group of highly anticipated tech listings that could make 2026 a banner year on Wall Street.
The exact timing and size of the IPO have not been disclosed because the filing is confidential, allowing the company to avoid public scrutiny until it is ready to market its shares. Under U.S. securities rules, companies with revenue below a certain threshold can confidentially submit draft registration statements, a process designed to help emerging growth companies gauge investor appetite without revealing sensitive data prematurely.
An unpublished route to the public markets
Anthropic's announcement comes as market watchers expect a wave of multibillion-dollar listings. SpaceX, the aerospace company with a dominant position in American space launches, has also filed for what many expect to be a record-breaking IPO. Meanwhile, OpenAI, one of Anthropic's closest competitors, is reportedly preparing its own public offering later in 2026. The combined activity points to a climate in which investors are eager to back deep-technology companies that have moved from research projects to real revenue engines.
Confidential filings are common among high-profile startups. They allow companies to begin the SEC review process quietly and delay the release of financial statements, business models, and risk factors until just before a formal roadshow. For companies like Anthropic, whose data and security practices may receive intense regulatory scrutiny, this approach gives executives more control over the narrative.
From startup to AI contender in three years
Anthropic was founded in 2021, but its ascent has been unusually rapid even by the standards of the AI industry. The company has concentrated on building AI systems that are useful to professional users, especially programmers and large enterprises, rather than chasing a broad consumer audience. This narrower focus has allowed it to deploy its resources on what it calls Claude models, which are designed for tasks such as code generation, document analysis, and complex reasoning.
The company first gained widespread popularity with programmers last autumn, when its Claude Opus 4.5 model became widely used. Developers appreciated its ability to work through complicated coding problems, review large codebases, and produce reliable outputs. Positive word-of-mouth helped Anthropic become one of the preferred AI providers in software development circles, despite intense competition from OpenAI, Google, and other large technology companies.
More recently, Anthropic has drawn attention for claims about its upcoming Claude Mythos model. According to the company, Mythos is significantly more capable than competing tools at identifying security flaws in computer networks. Anthropic said it has worked with banks and government agencies to use the model to test and protect critical systems before its official release. The security angle is likely to be important in its IPO story, because it suggests a path to revenue that does not depend only on general consumer chatbots.
Revenue surge and the profitability question
The company's decision to go public comes at a moment when its financial trajectory is improving. Last month, the Wall Street Journal reported that Anthropic's revenue was on track to more than double in the quarter ending in June. At that pace, the company would record its first profitable quarter during that period. The milestone has been seen as validation for Anthropic's strategy of embedding its AI tools into business workflows, where customers are willing to pay for tangible productivity and security improvements.
Still, the company has reportedly warned that future quarters may not show the same financial result. Anthropic is increasing spending on the massive computing infrastructure needed to train and operate advanced AI models. Those costs are among the largest in the technology industry, and they tend to grow quickly as models become larger and more capable. For Anthropic, the path to sustainable profits may rely on achieving economies of scale and on negotiating favorable access to computing resources.
Data centre deals and AI infrastructure costs
One of Anthropic's most striking recent agreements is with SpaceX. The company has reportedly agreed to use capacity at SpaceX's Colossus 1 and Colossus 2 data centres for a reported $1.25 billion per month, or about 930 million pounds. The arrangement underscores how far the AI industry has moved in its reliance on specialized computing power. Data centres are no longer just warehouses of servers; they have become strategic assets that can determine whether an AI company can compete at the frontier of model development.
SpaceX, like Anthropic, is not currently profitable, despite its dominance in the space launch market. That has not prevented investors from valuing SpaceX highly, nor has it deterred the company from seeking a public listing. Similarly, OpenAI is understood to be not profitable. The willingness of major AI and space companies to go public without strong bottom lines is a reminder that this era of public-market investing is often driven by growth expectations and market positioning rather than current earnings.
A valuation race with OpenAI
Anthropic's most recent private funding round valued the company at $965 billion. That number puts it above OpenAI, which was most recently valued at $852 billion. The reversal is notable. OpenAI had long been considered the leader of the AI startup pack, especially after ChatGPT made generative AI a mainstream phenomenon. Yet Anthropic's steady progress with professional users, combined with a perceived focus on safety and security, has narrowed the gap and, in the eyes of some private investors, moved Anthropic ahead.
Valuations of this scale have generated debate about whether private market expectations are too high. Anthropic is still a young company with significant costs and a limited operating history. If public-market investors do not accept the price set in private funding rounds, the company could face an awkward adjustment during its roadshow. However, the surge in demand for AI tools, particularly among large enterprises, suggests that investors may be willing to look past short-term losses.
Wall Street's uneven embrace of AI
Anthropic's filing will also be tested by an important reality: while there is broad enthusiasm for AI, the technology has not yet proven itself in many everyday tasks. Industry analysts have pointed out that many foundational models and AI agents still make mistakes, require careful human supervision, and are not easily integrated into legacy systems. Gartner, a research firm, has estimated that it could take two to five years before foundational models or AI agents become broadly productive for routine business use.
That prediction has not stopped venture and public investors from pouring hundreds of billions of dollars into AI-focused companies. But it does raise concerns for a company like Anthropic, which will need to convince shareholders that it can continue expanding revenue rapidly enough to justify its huge valuation. The company's focus on security may help it win high-value contracts from governments and financial institutions, as those buyers tend to be less sensitive to price and more concerned about reliability. Government contracts also place great importance on trustworthy technology, giving Anthropic another possible avenue for durable growth.
As Anthropic moves toward Wall Street, observers will be watching a handful of key dates. The SEC review process is confidential, but details about the company's financials will become public once it files a formal prospectus. If market conditions remain strong, Anthropic, SpaceX, and possibly OpenAI could turn 2026 into a turning point for technology investing, with a new generation of infrastructure-heavy companies testing whether public investors have the same appetite for risk that private investors demonstrated. Anthropic's own journey from research startup to IPO candidate in just a few years shows how rapidly the center of gravity in technology has shifted toward artificial intelligence.
