The Next Mega-IPO Is an AI Lab: Anthropic Moves Toward a Public Filing
Key Points
- Anthropic confidentially filed draft IPO paperwork on June 1, 2026, and may publicly file as soon as this month.
- The company carries a roughly $965 billion valuation after a $65 billion funding round, reportedly surpassing OpenAI for the first time.
- Expected Q2 2026 revenue reached about $10.9 billion, more than double the prior quarter.
- Annualized run-rate revenue is projected to exceed $50 billion by the end of July 2026, up from roughly $4 billion a year earlier.
- Goldman Sachs, JPMorgan, and Morgan Stanley are lined up to underwrite the listing.
- A Pentagon supply-chain-risk designation looms as a genuine threat to future government revenue.
Anthropic Nears a Landmark Filing
Anthropic has moved with unusual speed toward the public markets. The company filed confidential draft paperwork on June 1, 2026, and reporting now indicates it could flip to a public filing this month — the trigger that would set a fall debut in motion. Moreover, that timing matters competitively, because it would position Anthropic to list ahead of OpenAI, the rival it has chased and, on several fronts, recently overtaken.
The valuation underscores the stakes. Anthropic reached a roughly $965 billion valuation after a $65 billion funding round, and that figure reportedly surpassed OpenAI’s for the first time. Even so, investors should treat the number as a moving target: some private and prediction markets already price the eventual float well higher, so the final valuation remains one of the deal’s biggest open questions.
The Numbers Behind the Hype
Strip away the buzz, and the growth figures explain the enthusiasm. Anthropic expects Q2 2026 revenue of about $10.9 billion, more than doubling the prior quarter — a pace few companies at any size have matched. Furthermore, the trajectory looks even more dramatic on a run-rate basis: the company projects annualized run-rate revenue above $50 billion by the end of July 2026, up from roughly $4 billion just a year earlier.
Because that curve reflects surging enterprise demand for AI tools, it forms the core of the bull case. As a result, underwriters Goldman Sachs, JPMorgan, and Morgan Stanley are preparing to market a business whose top line is compounding faster than almost anything Wall Street has seen.
The Risks Investors Should Weigh
The story carries real counterweights, and a serious buyer will study them closely. Most concretely, the Pentagon designated Anthropic a supply-chain risk, a label that could jeopardize billions in future government revenue if it hardens into policy. Consequently, the company’s defense and public-sector ambitions face an overhang that no revenue chart erases.
Valuation adds a second caution. At nearly $1 trillion before it even prices, Anthropic will ask public investors to underwrite enormous expectations, and AI economics — soaring compute costs chief among them — remain unproven at this scale. Therefore, the same growth that excites the market also demands a level of execution the company has yet to prove over a full public-company cycle.
The Race With OpenAI
Competition frames the entire narrative. Anthropic has outpaced OpenAI on coding and cybersecurity capabilities, while OpenAI has contended with leadership changes and reports of missed internal targets. As a result, the momentum has shifted, and Anthropic now approaches the IPO window as the field’s ascendant name rather than its perennial challenger.
Both labs, notably, lean on the same banks and eye the same investors, so their listings will inevitably invite side-by-side comparison. Because the market can absorb only so much AI-IPO supply at once, whichever company files first may capture the lion’s share of attention — and capital.
What It Means for Investors
Anthropic’s march toward a public filing hands investors the clearest look yet at the economics of frontier AI. A near-$1 trillion valuation, revenue compounding toward a $50 billion run-rate, and a fall listing window together make this the most consequential IPO on the calendar. Even so, the Pentagon overhang and unproven margins mean the debut carries as much risk as promise.
Ultimately, Anthropic is about to test whether public markets will pay private-market prices for AI’s fastest-growing business. For now, the countdown has begun — and a public filing this month would turn one of the year’s most anticipated deals from rumor into reality.
