Anthropic's Q3 Revenue Hits $16.8 Billion, Turning a Profit Ahead of IPO

Anthropic is making more money, faster, than almost anyone expected.

The AI lab behind the Claude models reportedly told institutional investors at a closed-door meeting in San Francisco on Wednesday that its third-quarter revenue hit $16.8 billion — a 45% jump from the second quarter. The figures came from an investor who attended the briefing, speaking to Reuters, and were separately reported by the Financial Times.

The growth curve is steep

The numbers tell a story of breakneck acceleration. According to the reports, Anthropic pulled in $4.7 billion in the first quarter of this year and $11.6 billion in the second. That puts third-quarter revenue at roughly $67 billion on an annualized basis.

Even more notable: the company reportedly said it turned a profit in the quarter on an adjusted basis. For a company that is pouring staggering sums into chips, data centers, and computing power, adjusted profitability is a milestone the market has been waiting for.

It matters because the meeting was not just a business update. It was an investor day meant to familiarize prospective buyers ahead of Anthropic’s hotly anticipated initial public offering.

The IPO stakes

Anthropic’s listing is expected to precede a public offering by rival OpenAI, making it the first real test of how public markets value a heavily unprofitable AI lab chasing massive scale. Reuters has reported that the debut is likely to be pushed until after the November US midterm elections.

The company is reportedly targeting a valuation of over $2 trillion. That would make it one of the largest public debuts in history — and the financials disclosed this week are the centerpiece of the pitch.

Investors will be weighing the revenue surge against the cost side. Reuters reported last month that Anthropic has committed hundreds of billions of dollars in future spending under long-term agreements for cloud services, computing, and infrastructure. The business model is simple to describe and hard to execute: grow revenue faster than the enormous bills for running frontier AI systems.

The compute bill behind the growth

Revenue is only half the story. Building and running frontier models requires capital at a scale the tech industry has never seen, and Anthropic’s spending commitments reflect it.

Last month, Reuters exclusively reported that Anthropic had committed hundreds of billions of dollars in future spending through long-term agreements covering cloud services, computing, and infrastructure. That kind of locked-in spend is the price of staying in the frontier race — and it is why investors focus as much on cash generation as on model benchmarks.

The company’s history shows how fast the bill grows. Reported figures from Reuters’ coverage of Anthropic’s confidential prospectus put 2025 revenue at roughly $4.6 billion with about $42 billion in net losses, of which about $34 billion was an accounting charge and roughly $8 billion was operating losses. Computing alone reportedly cost $7.3 billion in 2025 — 58% of total operating expenses.

Against that backdrop, reaching $16.8 billion in a single quarter — and reportedly turning an adjusted profit — is the inflection the bull case needed. The bear case is unchanged: nobody knows where the spending curve flattens.

A market that needed reassurance

The timing of the disclosure mattered. AI stocks have been whipsawed this month. Reports of OpenAI’s own revenue numbers last week revived fears about whether the AI buildout can pay for itself, and Wednesday’s session saw sharp losses in AI-linked names like CoreWeave, Dell, and AMD alongside a hot inflation reading.

Anthropic’s numbers landed in the middle of that selloff. Futures briefly wobbled on the headlines, a sign that even strong results now get filtered through the same question: how much of this revenue is durable, and how much is being recycled into the next round of compute bills?

That is the question the IPO will answer. Anthropic’s public debut is being positioned as the first clean market verdict on the economics of frontier AI — before OpenAI’s own listing forces the comparison. With Google and Amazon on both sides of the table as investors, suppliers, and rivals, the offering will be scrutinized as a proxy for the whole sector.

What investors heard on Wednesday was the strongest version of the growth story. The S-1, when it finally becomes public, will show whether the costs cooperate.

What remains unclear

A few caveats are in order. These figures come from a single investor’s account of a closed-door meeting, not from a public filing. Anthropic’s S-1 financial statements are not yet public, and CNBC previously reported that the company filed its confidential draft with US regulators earlier this year.

It is also unclear exactly what counts as revenue in the numbers Anthropic shared — CNBC noted it is not known whether partner revenue is included, and “adjusted basis” profitability can exclude significant costs. The full picture will have to wait for the S-1.

Still, the direction of travel is hard to argue with. From $4.7 billion to $16.8 billion in three quarters is the kind of growth curve that makes a $2 trillion valuation argument at least plausible. The question the public market will answer next is whether the curve can outrun the costs.
