The headline number moved twice in three months
Anthropic's revenue for the second quarter of 2026 has been reported at two different figures within the space of a few months, and the gap between them is the story. In May, a Wall Street Journal report on documents Anthropic had shared with prospective investors put the company's internal Q2 projection at $10.9 billion. By mid-August, Bloomberg News reported that the preliminary actual figure, based on documents it had seen, came in above $11.5 billion, roughly $600 million over what the company itself had told investors to expect just months earlier. Anthropic declined to comment when contacted about the Bloomberg figures, and both outlets note the numbers are preliminary and could still be revised before any final reporting.
What the growth looks like quarter over quarter
The scale of the increase is large by any standard. Anthropic's own investor materials described Q1 2026 revenue of roughly $4.8 billion, projecting Q2 growth of 130 percent from there to reach $10.9 billion. The later, preliminary actuals put Q1 2026 revenue at $4.73 billion and Q2 at more than $11.5 billion, and put the year-over-year comparison at roughly 14-fold growth versus Q2 2025 revenue of $787 million. Whichever set of figures ends up closer to the final audited number, the direction is the same: quarterly revenue has been compounding at a pace few software companies of any kind have sustained.
The profit figure is the more unusual milestone
Revenue growth at an AI (artificial intelligence) lab is not new. What is new is Anthropic's claim, per the May investor documents, of a first-ever quarterly operating profit of $559 million, and Bloomberg's August reporting that the company did in fact post positive adjusted operating income for the quarter. AI labs have historically burned enormous amounts of cash on the computing power needed to run their models, and Anthropic's own figures show why that has started to change: the investor materials put compute cost at 71 cents per dollar of revenue in Q1 2026, falling to 56 cents per dollar in Q2. That 15-cent improvement, on a revenue base of roughly $11 billion, is a large part of where the projected profit came from.
Where the revenue is coming from
The investor materials attributed the jump to enterprise customers adopting Anthropic's tools for coding and cybersecurity work, rather than to consumer subscriptions. One data point stands out: Claude Code, Anthropic's coding-focused product, is reported to have crossed a $1 billion annualized revenue run rate within six months of its launch. That is a fast ramp for a single product line inside a company whose flagship business, until recently, was API (application programming interface) access to its Claude chatbot models sold to other software companies.
How this compares to the competition
By May 2026, Anthropic's annualized revenue run rate stood at about $47 billion, ahead of OpenAI's reported run rate of roughly $40 billion at a similar point. Run rate is a projection, not booked revenue, so it should be read as a snapshot of momentum rather than a guaranteed outcome, but it captures the state of a race between the two companies that both are, by every public account, still spending heavily to win. Reporting on the Q2 numbers frames the growth explicitly against that OpenAI rivalry: enterprise buyers currently choosing between the two companies' coding and agent tools are a large part of what is driving both firms' top lines upward at the same time.
What it means in practice
For businesses buying AI tools, the operating profit figure matters more than the revenue figure. A vendor burning cash on every dollar of revenue is a vendor whose pricing, product roadmap or very existence can change abruptly if its funding environment shifts; a vendor approaching break-even on operations has more room to hold pricing steady and invest predictably in the products enterprise customers are already paying for. None of these numbers are final. Anthropic has not published them itself, both outlets sourced them from documents shown to investors rather than from company statements, and the company would not confirm them on the record. Anyone relying on this for a purchasing or investment decision should wait for Anthropic's own disclosures, if and when it makes them, rather than treating leaked investor decks as audited results.
