Anthropic told prospective investors its second-quarter revenue topped $11.5 billion, a 14-fold jump from $787 million in the same period a year earlier, according to documents viewed by Bloomberg News. The Claude maker also posted positive adjusted operating income in Q2 2026, a milestone for a company burning through capital to keep pace with OpenAI. The numbers land as Anthropic prepares a fall IPO that would beat both OpenAI and DeepSeek to the public market.
Q2's $11.5 billion is more than double the $4.73 billion Anthropic booked in Q1 2026, and it exceeds the roughly $10 billion in total revenue the company reported for all of 2025. Annualized run rate crossed $47 billion in May, ahead of the $40 billion figure OpenAI has disclosed, though Bloomberg noted the two companies may not calculate the metric the same way. The figures are preliminary and could still be revised before any prospectus is filed.
Coding is doing much of the work. Anthropic has captured a disproportionate share of the developer-tools market through Claude's integration into products like Cursor, GitHub Copilot alternatives, and its own Claude Code CLI, where enterprise seat expansion has been the dominant growth vector. That has translated into corporate contracts large enough to move a quarterly revenue line by an order of magnitude in twelve months.
Key facts
- 01Anthropic reported preliminary Q2 2026 revenue above $11.5B, up from $787M a year earlier and $4.73B in Q1 2026.
- 02The company posted positive adjusted operating income in Q2, per documents seen by Bloomberg News.
- 03Annualized run rate crossed $47B in May 2026, versus roughly $40B for OpenAI.
- 04Anthropic filed confidentially for an IPO with Morgan Stanley, Goldman Sachs, and JPMorgan Chase as underwriters.
- 052026 IPO listings have raised $256.4B, the most since 2021, according to Bloomberg data.
Anthropic filed confidentially for a listing and is working with Morgan Stanley, Goldman Sachs, and JPMorgan Chase, per prior Bloomberg reporting. CFO Krishna Rao is leading investor meetings, sources told CNBC, though early conversations have been high-level and have not touched specific valuation targets. A fall debut would give Anthropic access to public-market capital before its two closest competitors — OpenAI and China's DeepSeek, which is preparing an IPO filing that could come as soon as this year.
The timing is deliberate. AI companies are collectively spending hundreds of billions of dollars on model training, inference infrastructure, and specialized data centers, and private funding rounds — even Anthropic's — are running out of room to absorb that scale. A listing unlocks a different order of capital: equity issuance, follow-on offerings, and access to institutional investors who cannot deploy into private rounds.
The broader IPO market is cooperating. Listings in 2026 have raised $256.4 billion excluding SPACs and other vehicles, per Bloomberg data — the most in a single year since 2021. AI names are the driver, with public investors treating the sector as the successor to the mobile and cloud waves that defined the last two listing booms.
Anthropic's position looked considerably weaker eighteen months ago. The company was widely viewed as trailing OpenAI on consumer adoption, brand recognition, and API volume. Claude's push into agentic coding and long-context reasoning shifted that, and enterprise buyers — who care more about output reliability than chatbot mindshare — moved. The $787 million Q2 2025 figure is the reference point for how quickly that shift compounded.
The caveats are real. Anthropic has not disclosed gross margins, and inference costs at frontier-model scale remain the industry's least-transparent line item. Positive adjusted operating income is not the same as GAAP profitability, and the "adjusted" qualifier typically excludes stock-based compensation, which is substantial at every frontier lab. Public-market investors will demand line-item disclosure that private rounds did not, and the gap between run-rate revenue and audited financials has tripped up prior tech IPOs. DeepSeek's cost structure — and any pricing pressure it exerts on API rates — is a separate unknown.
For the AI market, Anthropic going public first would reset how the sector is valued. OpenAI's private secondary trades have implied valuations north of $500 billion, but those are illiquid marks. A live Anthropic ticker with quarterly filings would give every other AI company — public and private — a comparable, and it would give enterprise buyers hard numbers on the financial durability of the vendor they are betting their workflows on. The IPO window is open now; the companies that step through it in the next six months will define the sector's public-market template for the rest of the decade.
