Key comparisons:

• Quarter-over-quarter: Q2 ($11.5B+) roughly doubled Q1 ($4.8B), a more than 130% sequential increase .
• Year-over-year: Revenue rose from roughly $787 million in Q2 2025 to more than $11.5 billion .
• Annualized run rate: Anthropic's run rate soared from roughly $14 billion in February 2026 to over $47 billion by mid-2026 .

Prior to these results, Anthropic's revenue for the full year 2025 was about $10 billion . The Q2 2026 quarter alone eclipsed that entire annual figure.

How Anthropic Compares to Rival OpenAI

OpenAI is on track to generate annualized revenue of more than $40 billion based on current performance, roughly doubling its run rate from the end of 2025 . OpenAI's CFO told employees in July that the company's annualized recurring revenue in July alone topped its entire Q2 total .

In absolute run-rate terms, the two companies are now close: OpenAI at $40B+ annualized run rate versus Anthropic's roughly $47B run rate. However, Anthropic's growth trajectory is steeper on a percentage basis, and its Q2 2026 quarterly revenue of $11.5 billion exceeded OpenAI's entire Q2 based on disclosed run-rate dynamics, though direct quarterly comparisons are complicated by different disclosure methods.

First Operating Profit: A Landmark for AI Labs

Anthropic achieved its first-ever quarterly operating profit in Q2 2026 — a landmark for the company and for major AI labs . The operating profit was approximately $559 million (including model training costs, excluding stock-based compensation) .

Compute cost per revenue dollar played a key role in reaching profitability. It fell from 71 cents in Q1 to 56 cents in Q2, a key driver of margin improvement . This profitability milestone came two years ahead of the company's original 2028 target .

It is worth noting that the $559 million figure is based on projections shared with investors, not audited public filings. Anthropic is not yet subject to public company reporting requirements, and the accounting methods used are not fully transparent .

IPO Preparations: What to Expect This Autumn

Anthropic is targeting an IPO as soon as October 2026, with roadshow meetings between executives and potential investors already underway .

Investment banks: The company selected Morgan Stanley, Goldman Sachs, and JPMorgan Chase as lead underwriters . These banks are managing the roadshow and investor meetings .

SEC filing: Anthropic submitted a confidential S-1 filing with the SEC on June 1, 2026, at its then-current $965 billion private valuation .

Valuation expectations: This is the most dynamic figure. Anthropic's most recent private valuation was $965 billion, set in a $65 billion Series H round that closed in late May 2026 — up from $380 billion at the Series G just three months earlier . However, investor discussions are now centered around a potential IPO valuation exceeding $2 trillion, according to six backers cited by the Financial Times . At $2 trillion, it would eclipse SpaceX, which went public at $1.77 trillion in June . Forbes notes that current market discussions among investors point to a $2+ trillion range .

Important caveat: The $2 trillion figure comes from investors and market chatter, not from the company itself. Anthropic has not fixed a valuation, and the final IPO price will depend on market conditions, roadshow demand, and the pricing of its Nasdaq debut under the expected ticker ANTP .

Some investors expect the company's annualized revenue to reach between $100 billion and $120 billion by the end of 2026 — up more than tenfold from the current run rate .

What Happens Next

The next milestones to watch are the pricing of the IPO, which could happen as soon as September, and the public market's reception to a company trading at a massive premium to its current revenue. If the IPO prices near $2 trillion, it would immediately become the largest public listing in history and the biggest test yet of whether public market investors share the private market's conviction about AI's trajectory.
