Just days after confidentially filing paperwork with regulators, Anthropic has chosen its lead banks for a public debut that could reshape how markets value artificial intelligence companies. Morgan Stanley and Goldman Sachs will head the offering, with JPMorgan Chase also playing a key role. The move, first reported by Bloomberg, signals the AI startup’s readiness to test public appetite after years of breakneck private fundraising.
The timing feels deliberate. Anthropic submitted its draft S-1 to the SEC on June 1, according to its own announcement. That filing gives the company flexibility. It can refine disclosures with regulators before any shares hit the market. Yet the decision to go public now comes amid fierce competition. OpenAI works with some of the same banks on its own plans. SpaceX prepares for its own listing. All three chase investor dollars in what bankers describe as one of the richest windows for technology debuts in years.
But size alone doesn’t capture the stakes. Anthropic’s latest private round closed at a $965 billion post-money valuation after it raised $65 billion in Series H funding. The round, announced on the company’s site, was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. Such a figure once seemed unthinkable. Now it serves as the baseline for what investors might pay when shares begin trading. Some analysts already float $1 trillion or higher at debut.
Revenue tells part of the story. The company’s annualized run rate jumped from roughly $4 billion in mid-2025 to $50 billion by July 2026. In one recent quarter it posted $559 million in operating profit on $10.9 billion of revenue. Much of that growth stems from demand for coding tools powered by its Claude models. Enterprises pay to automate software development. That use case has proven stickier than pure chat interfaces.
Yet profitability hasn’t quieted questions about spending. Corporate customers have begun to voice sticker shock over AI costs. Axios reported on that backlash just after the filing. OpenAI’s Sam Altman himself called the concern fair. For Anthropic the tension matters. Its IPO documents will need to persuade investors that current losses on infrastructure can give way to sustainable margins. The company burns cash on massive clusters of Nvidia chips. One contract alone highlights the scale.
SpaceX’s own IPO prospectus, referenced in recent coverage, reveals Anthropic pays $1.25 billion per month for compute through May 2029. The deal covers 325,000 Nvidia GPUs. Either party can end it after an initial three-month period with 90 days’ notice. The arrangement underscores how even well-funded AI firms depend on others for raw power. It also creates an interesting overlap. Elon Musk’s companies compete directly with Anthropic in chatbots and model development.
Founding history adds another layer. Dario Amodei left OpenAI in 2021 to start Anthropic with several colleagues. They emphasized safety and constitutional AI from the start. That positioning helped attract backing from Amazon and Google. Both cloud giants hold significant stakes and provide infrastructure. Amazon committed more than $8 billion in prior deals. Google sits as a top shareholder. Those relationships could appear in greater detail once the full S-1 becomes public.
Wall Street’s eagerness to underwrite the deal reflects more than prestige. Morgan Stanley led equity capital markets revenue last year but has faced pressure from Goldman. Securing the top spot here would deliver a win. Goldman, fresh off leading SpaceX’s underwriting, stands to extend its streak in marquee listings. JPMorgan rounds out the group. The trio already participated in Anthropic’s recent private rounds. Their familiarity with the business reduces execution risk.
Earlier this year the banks offered clients sharply different terms for access to a $30 billion raise. The Financial Times detailed how Morgan Stanley charged some wealth clients a 1% fee while Goldman’s pricing varied. Those disparities sparked quiet complaints about fairness. They also showed how demand for Anthropic shares outstripped supply even in private markets. The company’s valuation climbed from $61.5 billion in March 2025 to $183 billion by September, then $380 billion in February 2026. The latest round nearly tripled that mark again.
Such acceleration carries risks. Some early investors sat out the most recent round. They preferred to wait for the IPO, according to Forbes reporting. Bankers once projected a listing valuation between $400 billion and $500 billion. That math no longer holds. With private marks near $1 trillion, any public price below current levels could leave recent backers underwater. Lock-up periods only heighten the pressure.
Regulatory and geopolitical factors loom too. The Pentagon placed Anthropic on a supply-chain risk list, citing national security. That designation, noted in recent coverage, creates uncertainty for government contracts. It also highlights broader tensions. Lawmakers worry about AI’s dual-use potential. Anthropic has resisted calls to remove certain safety guardrails. CEO Dario Amodei drew a firm line against applications in autonomous weapons or mass surveillance. The stance cost business but reinforced the company’s brand.
Still, growth continues. Claude’s coding abilities drive adoption. Developers report higher productivity. Enterprises integrate the models into internal tools. If those gains persist, revenue could keep climbing even as training costs mount. The IPO will force greater transparency on exactly how those economics balance. Investors will scrutinize customer concentration, model performance metrics, and capital expenditure forecasts.
The filing also arrives as markets digest other AI-related debuts. SpaceX aims for a $1.8 trillion valuation in its own offering. OpenAI eyes a September listing that could top $1 trillion. The cluster creates both opportunity and fatigue. Too many massive tech floats might strain demand. Or they could validate the sector’s promise and draw fresh capital from pension funds and retail brokers.
Anthropic’s choice of banks suggests confidence. Morgan Stanley and Goldman Sachs bring deep networks of institutional buyers. Their research arms already cover peers in software and semiconductors. That expertise should help craft a narrative around long-term AI infrastructure spending. Yet the real test comes later. When the quiet period ends and executives begin roadshows, they must convince skeptics that today’s valuations reflect genuine earnings power rather than hype.
For now the filing itself changes little on the surface. No share count or price range appears yet. The SEC review could take months. Market conditions may shift. But the signal feels unmistakable. One of the highest-valued private companies in history prepares to enter public view. Its success or stumbles will influence funding for the next generation of AI startups. It will shape compensation for engineers. And it will test whether Wall Street can price a technology whose capabilities continue to evolve faster than accounting standards can measure.
So the banks line up. The documents move through regulators. And the industry watches. Anthropic’s debut won’t settle every debate about AI’s future. It will, however, set a very public benchmark for what the market thinks that future is worth.
