Anthropic's Revenue Explodes to $65B Run Rate, Dwarfing OpenAI

Anthropic is on a revenue trajectory that makes even the most aggressive tech growth stories look pedestrian. The AI model maker’s annualized revenue run rate surpassed $65 billion at the end of July, according to Bloomberg, up from just $47 billion in May and a mere $9 billion at the end of last year. That’s not just growth, that’s acceleration at a scale most companies can only dream about.

For context, OpenAI has doubled its revenue to $40 billion, up from $20 billion at the end of 2025. While that’s impressive on its own, Anthropic’s trajectory suggests it’s capturing investor imagination in a completely different way. The two companies may calculate their revenue metrics differently, but when one is outpacing the other this dramatically, the math becomes harder to explain away.

The IPO Question

Both Anthropic and OpenAI have filed confidential IPO paperwork, and here’s where things get really interesting. Anthropic is expected to hit the public markets ahead of OpenAI, possibly as soon as this fall. When it does, the company is seeking a public valuation of $2 trillion or more, according to the Financial Times. That would make it the largest market debut on record, full stop.

To put that in perspective, Anthropic was last valued at $965 billion in late May when it raised a $65 billion round. A $2 trillion valuation represents roughly a 2x increase in just months. If investors are pricing in continued acceleration at the current rate, that math actually tracks with investor expectations.

Where the Money Is Coming From

The real question nobody’s asking loudly enough: is this revenue real, or is it a projection game? Annualized revenue run rate is a snapshot metric that extrapolates recent performance into a full year. If Anthropic’s customers suddenly stop adopting its services, or if usage plateaus, the narrative changes overnight.

That said, investors aren’t betting on fairy tales. They’re expecting Anthropic to continue growing at approximately the same rate for the remainder of the year, finishing 2026 between $100 billion and $120 billion. That’s not a guess, that’s a conviction bet made with tens of billions of dollars. When that kind of capital is on the line, people tend to do their homework.

The company hasn’t publicly responded to requests for comment on these figures, which is standard operating procedure for a pre-IPO company. Everything is filtered through the Financial Times and Bloomberg, which have access to investor presentations and financial projections.

What This Means for Startups and the Industry

Anthropric’s trajectory is reshaping how investors think about AI companies. The model isn’t about having the best technology anymore, it’s about capturing mindshare and revenue share before someone else does. Winner-take-most dynamics are intensifying, and the spoils are going to the companies that can scale fastest.

The IPO timing matters too. If Anthropic goes public in the fall at a $2 trillion valuation, it’ll set a psychological anchor for the entire AI industry. OpenAI’s eventual IPO will be benchmarked against it. Every other AI company’s funding round will be measured against it. That’s market power.

The fact that both companies have filed confidential IPO paperwork suggests they’re serious about going public sooner rather than later. The AI gold rush is entering its extraction phase, and the miners with the fullest buckets are heading to market first.

If Anthropic’s revenue projections hold and it launches at a $2 trillion valuation, it’ll rewrite the record books and reset expectations for what’s possible in tech. That’s not just a milestone; it’s a paradigm shift.
