Anthropic<\/a>, the developer behind the AI chatbot<\/a> Claude, has taken its first major step toward becoming a publicly traded company. On June 1, the company submitted a confidential draft S-1 registration statement to the U.S. Securities and Exchange Commission (SEC)<\/a>, formally initiating the process for an initial public offering. The move comes just four days after the company closed its Series H funding round at a valuation of approximately $965 billion \u2014 roughly 153 trillion Japanese yen \u2014 marking the beginning of a new era in which frontier AI companies test the public markets.<\/p>\n

Confidential S-1 Filing Signals Intent<\/h2>\n

Anthropic confirmed the filing in a public statement, noting that the number of shares to be offered and the price range have not yet been determined. The company emphasized that the actual IPO timeline remains subject to market conditions and other factors, a standard caveat in confidential filings.<\/p>\n

Confidential filing, also known as confidential submission, is a procedure permitted under the JOBS Act that allows companies to keep their registration documents private while the SEC conducts its review. The approach has become routine for large technology IPOs in recent years. SpaceX followed the same process before moving to a public filing in May, and multiple reports indicate OpenAI also submitted a confidential S-1 around the same period. Under normal procedure, the public version of the S-1 will be released several weeks before the company begins its roadshow to pitch investors.<\/p>\n

The speed of Anthropic’s move is noteworthy. On May 28 \u2014 just four days before the S-1 submission \u2014 the company raised $65 billion in its Series H round, bringing its post-money valuation to $965 billion. That funding round featured Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital as co-lead investors, with participation from Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN, among others. For all practical purposes, the Series H functioned as a pre-IPO round, setting the stage for the public offering that now appears imminent.<\/p>\n

From $10 Billion to $470 Billion ARR in 15 Months<\/h2>\n

Anthropic’s growth trajectory has broken every convention in the software industry. The company’s annualized recurring revenue (ARR) stood at roughly $10 billion at the end of 2024. By the end of 2025, that figure had climbed to $90 billion. In February 2026, it reached $140 billion. By April, ARR hit $300 billion, and in May, it surged past $470 billion \u2014 approximately 74.9 trillion yen. That represents a roughly 47-fold increase in just 15 months.<\/p>\n

To put this in perspective: Salesforce took roughly 20 years to reach $300 billion in annual revenue. Anthropic achieved that milestone in a fraction of the time, reflecting the unprecedented demand for frontier AI capabilities in the enterprise market.<\/p>\n

The primary driver of this growth is Claude Code, the company’s AI-powered coding assistant. Launched publicly in May 2025, Claude Code crossed $10 billion in ARR within six months. By February 2026, it had exceeded $25 billion. Enterprise contracts now account for more than half of total revenue, and the rapid expansion of enterprise customers is directly reflected in the revenue curve.<\/p>\n

Perhaps more striking than the top-line growth is the improving profitability picture. Anthropic generated $48 billion in revenue in Q1 (January through March 2026). In Q2 (April through June), revenue more than doubled to $109 billion, and the company is projected to report an operating profit of approximately $5.9 billion for the quarter. If realized, this would mark the first quarterly profit for a frontier AI lab. However, analysts note that this profit includes what is described as a “ramp-period discount” on a large compute contract with SpaceX (xAI), and the company’s ability to sustain full-year profitability remains uncertain.<\/p>\n

What the Valuation Timeline Reveals<\/h2>\n

The trajectory of Anthropic’s valuation tells a story about the scale of capital flowing into the AI sector. In March 2025, the company’s Series E round valued it at $615 billion. By September 2025, the Series F had pushed that figure to $1.83 trillion. In February 2026, the Series G reached $3.8 trillion. And in May 2026<\/a>, the Series H closed at $9.65 trillion. In just 14 months, the valuation expanded more than 15-fold.<\/p>\n

Anthropic has not yet crossed the $1 trillion mark, but if its IPO prices at or above the Series H valuation, the company would debut with a market capitalization rivaling Apple, NVIDIA, and Microsoft \u2014 all within five years of its founding.<\/p>\n

How Does Anthropic’s IPO Compare to SpaceX and OpenAI?<\/h2>\n

Anthropic’s filing is one component of a larger wave of AI and technology IPOs expected in 2026. SpaceX filed its S-1 publicly on May 20 and is targeting a Nasdaq listing around June 12<\/a> under the ticker “SPCX,” with a target valuation between $1.75 trillion and $2 trillion. If achieved, it would be the largest IPO in history. However, the company carries significant debt from its merger with xAI, and reports indicate it posted a net loss of $49 billion in 2025 \u2014 raising questions about the financial profile it will present to public investors.<\/p>\n

OpenAI is also reported to have filed a confidential S-1 on May 22. Goldman Sachs and Morgan Stanley are serving as lead underwriters, and the company is reportedly targeting a listing as early as September 2026 at a valuation exceeding $1 trillion. Its most recent funding round \u2014 a $1.22 trillion raise completed in March at an $852 billion valuation \u2014 served as its own pre-IPO round.<\/p>\n

The combined fundraising target of these three companies could potentially exceed the total capital raised in the entire U.S. IPO market since 2022. Whether the public market can absorb this volume of AI-linked equity remains one of the most consequential questions for the broader market.<\/p>\n

Anthropic’s Unusual Governance Structure<\/h2>\n

One feature that distinguishes Anthropic from most IPO candidates is its corporate governance model. The company is registered as a Public Benefit Corporation (PBC) in Delaware, which means its board of directors has a legal obligation to pursue both shareholder returns and public benefit purposes.<\/p>\n

More distinctively, Anthropic has established a Long-Term Benefit Trust (LTBT). The LTBT is an independent body composed of AI safety and public policy experts. It holds a special class of Class T shares and has the authority to progressively appoint a majority of the board of directors. Unlike the typical dual-class structure where founders retain voting control, Anthropic’s model is designed to eventually transfer governance power to this independent “mission guardian.”<\/p>\n

For Anthropic, which has built its brand around responsible AI development and safety, the LTBT is a core element of its credibility. For investors focused on short-term returns, however, the structure introduces a governance discount \u2014 a potential drag on valuation stemming from the fact that ultimate control does not rest with shareholders. How Anthropic explains this arrangement in its public S-1 will be central to its IPO narrative.<\/p>\n

What the IPO Means for Claude Users in Japan and Beyond<\/h2>\n

Becoming a publicly traded company carries implications that extend beyond investors and analysts. For Claude users, the most immediate effects are likely to involve pricing and service stability.<\/p>\n

Until now, Anthropic’s revenue figures have been self-reported, and some analysts have questioned their consistency. As a public company, Anthropic will be required to report financial results under SEC oversight, which will bring greater transparency to its numbers. That same scrutiny, however, will also create pressure to demonstrate consistent profitability \u2014 pressure that could lead to API price adjustments or changes to subscription plans. The risk of price increases is non-zero, particularly if the company needs to show margin improvement to public market investors.<\/p>\n

On the positive side, the capital raised through the IPO could fund infrastructure expansion, model training, and product improvements. Faster response times, better model quality, and broader availability are all plausible outcomes if the company deploys its public market proceeds effectively.<\/p>\n

What is certain, as of now, is only what has been confirmed: the draft S-1 has been submitted to the SEC. The timing and pricing of the IPO remain undetermined. But the speed of the filing \u2014 just four days after a $65 billion funding round \u2014 signals that Anthropic intends to move decisively while the window for technology IPOs remains open.<\/p>\n","protected":false},"excerpt":{"rendered":"
