The first mover defines how markets value generative AI
Five years after its founding, Anthropic has stepped toward the public stage, filing confidential paperwork with the SEC to offer shares in what may become the defining financial event of the artificial intelligence era. Valued at nearly a trillion dollars, the San Francisco company joins a historic convergence of capital alongside SpaceX and rival OpenAI — a moment that will ask public markets to decide, for the first time, what the promise of generative AI is actually worth. The answer will set a yardstick not just for these companies, but for how humanity chooses to price its own technological future.
- Anthropic has filed confidential IPO paperwork with the SEC, targeting a 2026 listing at a staggering $965 billion valuation — edging past OpenAI's $852 billion and igniting a race to the public markets.
- The rivalry between Anthropic's Dario Amodei and OpenAI's Sam Altman — rooted in a personal falling-out — has transformed into a high-stakes contest over who defines how public investors value generative AI.
- Analysts are calling this the most scrutinized tech offering in history, warning that 2026 could either validate AI's trillion-dollar promise or deliver the most expensive lesson in narrative-versus-fundamentals public markets have ever seen.
- Anthropic is betting its credibility on a claim neither SpaceX nor OpenAI can match: it expects to turn a profit in the first half of 2026, driven by growing Claude sales.
- A shadow hangs over the listing — Anthropic's public clash with the Department of Defense over a $200 million contract that Amodei feared could enable mass surveillance or autonomous weapons deployment.
Anthropic, the San Francisco company behind the Claude chatbot, announced Monday that it has filed confidential paperwork with the SEC to go public this year — marking the first time a major AI-focused company will offer shares to ordinary investors. Founded just five years ago by Dario Amodei and a group of former OpenAI researchers, the firm carries a private valuation of more than $965 billion, placing it ahead of OpenAI's most recent $852 billion figure.
The filing intensifies an already fierce rivalry. Amodei departed OpenAI following disagreements with chief executive Sam Altman, and the two companies have since competed aggressively for the same customers and contracts. OpenAI is also reportedly preparing its own public offering, though Altman told CNBC on Monday the company was in no hurry. The race matters because, as one analyst put it, the first mover has a real chance to define how public markets value generative AI — setting the yardstick everyone else will be measured against.
The stakes extend well beyond the two companies. With SpaceX also expected to break valuation records, 2026 is shaping up as an unprecedented concentration of pre-IPO capital. Analysts have described Anthropic's offering as potentially the most scrutinized in tech history, with investors demanding answers about margins, profitability, and whether enormous AI valuations reflect financial reality or venture capital storytelling.
Anthropologic has tried to distinguish itself by projecting profitability in the first half of 2026 — a claim neither SpaceX nor OpenAI can currently make. Yet the company has not been without friction: a late-2025 dispute with the Department of Defense over a $200 million contract exposed tensions around government use of Claude, with Amodei publicly objecting to language he feared could enable surveillance or autonomous weapons. The coming months will reveal whether public markets share the confidence that private investors have already priced in.
Anthropic, the company behind the widely used Claude chatbot, announced Monday that it has filed confidential paperwork with the US Securities and Exchange Commission to go public this year. The move marks a watershed moment for artificial intelligence as a commercial sector—the first time a major AI-focused company will offer shares to ordinary investors on the open market.
The San Francisco firm, founded just five years ago by chief executive Dario Amodei and a small group of former OpenAI researchers, has been valued by private investors at more than $965 billion. That figure places it ahead of OpenAI, which most recently commanded a $852 billion valuation. Neither company has yet disclosed the price or number of shares it will offer, and Anthropic said those details would be determined as the process moves forward.
The race to the public markets reflects an intensifying rivalry between the two firms. Amodei left OpenAI after disagreements with its chief executive Sam Altman, and the two companies have since become fierce competitors, building similar technology and vying for the same customers and corporate contracts. OpenAI is also reportedly preparing to go public this year, though Altman told CNBC on Monday the company was not in a hurry. "We'll do it when it makes sense," he said.
What makes this moment historically significant is the sheer concentration of capital at stake. SpaceX is expected to break stock market records with its own valuation, and the potential listings of Anthropic and OpenAI are not far behind. Analysts describe the convergence as unprecedented. Troy Hooper, a leader in equity capital markets at Mergermarket, noted that neither company wants to be second. "The first mover has a real chance to define how public markets value generative AI, setting up the yardstick that investors will use to measure everyone else," he said.
Harrison Rolfes, a research analyst at Pitchbook, predicted Anthropic's offering would be "the most scrutinized public offering in tech history." Investors will scrutinize the company's margins, sales figures, and path to profitability—fundamental questions about whether the enormous valuations and steep costs of building AI systems actually make financial sense. Rolfes warned that 2026 could become either "the most consequential IPO cycle since the dot-com era or the most expensive lesson in narrative-versus-fundamentals that public markets have ever taught."
Anthropic has already signaled confidence in its business model. The company told investors it expects to turn a profit in the first half of 2026, driven by growing sales of Claude and related services. That claim distinguishes it from both SpaceX and OpenAI, neither of which is currently profitable. Yet the company has also faced scrutiny over its government relationships. Late last year, the Department of Defense insisted that Anthropic accept contract terms for a $200 million deal that would allow government agencies to use Claude for "any lawful use." Amodei publicly objected, expressing concern that the language could enable mass domestic surveillance or deployment in fully autonomous weapons systems. Despite that friction, Anthropic's customer base has continued to expand.
The coming months will test whether the market shares the enthusiasm of private investors. The 2026 IPO window will either validate the belief that generative AI represents a transformative technology worth nearly a trillion dollars, or it will expose a gap between the narratives venture capitalists have embraced and the financial fundamentals that public markets demand.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that Anthropic files before OpenAI, or vice versa?
The first one to list gets to set the valuation template. Once Anthropic's shares start trading, every other AI company gets measured against that price-to-sales ratio, that profitability timeline. It's like being the first restaurant to open on a new block—you define what people think a meal should cost.
But both companies are worth roughly the same amount right now. What changes when they go public?
Everything becomes visible. Right now, valuations are private opinions backed by venture capitalists who have skin in the game. Once shares trade publicly, thousands of investors with different time horizons and risk appetites start voting with real money. The price moves minute by minute. You find out if the market actually believes in the story.
Anthropic says it will be profitable this year. OpenAI isn't. Does that matter?
It matters enormously. Profitability is the thing that separates a company from a bet. If Anthropic can show it's making money while building cutting-edge AI, that's a different narrative than "we're spending billions hoping this works out." It gives the company a cushion if the market gets skeptical.
What's the Dario Amodei and Sam Altman tension really about?
They disagreed on how to build AI safely and how fast to move. Amodei wanted more caution; Altman wanted speed. Now they're both trying to prove their approach works by going public. It's personal and professional at once.
The Department of Defense contract controversy—does that hurt Anthropic's IPO prospects?
It could cut both ways. Some investors see it as a sign the government trusts the technology. Others worry about regulatory risk or the optics of AI being used in weapons. Amodei's public objection actually helped—it showed the company has principles, not just profit motive. But it's a live issue.
What happens if one of these IPOs flops?
Then the entire sector gets repriced downward. Right now, the market is betting on AI as the next transformative technology. If the first major company to go public disappoints—if the margins are thin, if growth slows, if the costs don't justify the revenue—then every other AI company's valuation gets questioned. It's all connected.
