Anthropic, the artificial intelligence company behind the Claude chatbot, has filed its S-1 paperwork with US regulators, offering a rare glimpse into its finances ahead of a planned initial public offering. The filing, made public on Monday, shows a company growing at breakneck speed but still burning through cash at an extraordinary rate.
For the first half of 2026, Anthropic reported revenues of approximately $16.3 billion, a figure that underscores the explosive demand for generative AI tools. Yet the same period saw net losses of $80.7 billion, a stark reminder that the AI industry's race for dominance comes at a heavy price. The company's costs, driven by massive computing infrastructure and talent acquisition, continue to outpace its income.
The IPO is expected to be one of the largest in recent memory. According to The Wall Street Journal, citing people familiar with the matter, the offering could raise as much as $100 billion, valuing Anthropic at upwards of $1.5 trillion. That would represent a significant leap from the $965 billion valuation the company commanded in May 2026.
AI's promise and peril
In its S-1 filing, Anthropic struck a dual tone, celebrating AI's potential while cautioning against its dangers. "We believe that AI is one of the most consequential technologies in human history," the company wrote. "If managed well, it could rapidly accelerate scientific innovation, greatly increase economic growth rates, bring cures for major diseases within reach, and solve problems that have resisted generations of human effort."
But the company also issued a stark warning: AI could bring "catastrophic or existential risks to humanity" if it is not "developed, deployed, and operated with appropriate safeguards, oversight, and security measures." This acknowledgment of risk is unusual for a company seeking public investment, and it reflects the growing scrutiny facing the AI sector.
Anthropic also flagged political and regulatory headwinds. "The political environment and our engagement with policymakers and public positions on AI regulation and safety could subject us to heightened scrutiny, political backlash, or disproportionate regulatory action," the filing noted. This comes as European regulators, including those in Brussels, are crafting comprehensive AI rules under the EU AI Act, and as national governments from Paris to Berlin debate how to balance innovation with oversight.
The company's warning echoes broader concerns raised across the continent. In recent months, European policymakers have grappled with the implications of AI for democracy, as seen in Anthropic's Claude slipping past a paywall to reach Georgia voter data, a development that raised eyebrows about AI's role in political processes. Meanwhile, the Elvis estate's lawsuit against Anthropic over AI training on 274 songs highlights the legal and ethical battles brewing over intellectual property.
Critics question the numbers
Not everyone is convinced by Anthropic's narrative. Gary Marcus, an emeritus professor at New York University and a vocal critic of the AI industry, took to X to accuse the company of "skirting the truth" in its filing. "Anthropic ducked Q3 in its S-1," he wrote. "That omission tells you all you need. Demand has dropped, economics haven't gotten worse. And a company that is allegedly built around trust is trying to skirt the truth."
Marcus's critique points to a broader debate about transparency in the AI sector. As companies like Anthropic and OpenAI race to scale, investors and regulators alike are demanding more clarity on how these technologies are developed and deployed. The omission of quarterly data, whether strategic or accidental, is likely to fuel further skepticism.
For Europe, the implications of Anthropic's IPO are significant. The company's technology is used by millions across the continent, from businesses in Frankfurt to startups in Tallinn. Its success or failure could shape the competitive landscape for European AI firms, which are already struggling to keep pace with US giants. As the EU pushes for digital sovereignty, the outcome of this IPO will be watched closely in Brussels and beyond.
The filing also comes at a time when AI's impact on daily life is under intense scrutiny. From climate disinformation emerging as a public health threat to concerns about job displacement, the technology's reach is vast. Anthropic's own warnings about existential risks add a layer of urgency to these debates.
As the IPO process unfolds, investors will have to weigh the company's soaring revenues against its staggering losses and the broader risks it has itself highlighted. For Anthropic, the path to public markets is a test of whether the AI boom can sustain its momentum—and whether the industry can convince the world that its benefits outweigh its dangers.
