Anthropic has a problem most startups would love to have. It's growing so fast that investors are struggling to agree on what the company is actually worth.
The company behind Claude is preparing for one of the biggest IPOs in tech history. But the closer it gets to Wall Street, the more uncomfortable the numbers become.
Not because people have stopped believing in AI. Quite the opposite.
The concern is how much money it takes to stay in the race.
Anthropic Has Come a Long Way From Being the Other AI Company
When Anthropic launched in 2021, it was mostly known for its founders, a group of former OpenAI employees who wanted to build AI with a stronger focus on safety.
For a while, OpenAI got most of the attention.
Then businesses started taking Claude seriously.
Anthropic found a particularly valuable audience among companies using AI for coding, research and everyday work. Unlike casual users experimenting with free chatbots, these customers are willing to pay for tools that save employees time.
That helped Anthropic generate roughly $16.3 billion in revenue during the first six months of 2026.
It's an extraordinary number for a five-year-old company.
But revenue only tells half the story.
Making AI Is Expensive. Staying Competitive Is Worse.
Anthropic reported a net loss of approximately $80.7 billion for the same period.
Before anyone panics, most of that figure came from an accounting adjustment related to financing, rather than money spent running the business.
Its operating loss was closer to $693 million.
Still, the underlying challenge is real.
AI companies need enormous computing power. Training new models costs money. Running them costs money. And just when a company has built something impressive, a competitor releases something better.
Anthropic has outlined hundreds of billions of dollars in future computing commitments.
That spending might eventually pay off. But investors are starting to ask how long companies can keep increasing their bills to defend their position.
OpenAI Makes the Timing Even More Interesting
Anthropic isn't entering the stock market in a quiet industry.
OpenAI is also raising huge amounts of capital, and both companies are competing for many of the same customers, engineers and investors.
That competition matters because Anthropic's valuation expectations have already shifted.
Reuters reported that discussions had moved toward a valuation of around $1.5 trillion, compared with earlier expectations closer to $2 trillion.
Nothing about that makes Anthropic a small business. It simply suggests investors are becoming more careful about how much they're willing to pay for future growth.
The Anthropic IPO Is Really a Test of AI Economics
For years, the biggest AI companies have been valued largely on what investors believe they could become.
An IPO changes that relationship.
Public investors will have financial statements to examine, quarterly results to compare and plenty of questions about profitability.
Anthropic has already shown that businesses will pay serious money for AI.
What it hasn't fully proved is how much of that money it can eventually keep.
That's what makes this IPO worth watching, even for people who have no intention of buying the stock.
We know AI is becoming a big business.
We're about to get a better idea of whether it's becoming a good one.
