Anthropic's IPO Filing: $8B Loss, $54.6B Compute Promise

Anthropic, the company behind the Claude AI model, recently shared its IPO prospectus with select partners. The target valuation? A staggering $2 trillion. But the fine print reveals a business that's growing fast—and burning cash even faster.

Revenue Soars, Losses Double

In 2025, Anthropic's revenue skyrocketed 12 times over, reaching nearly $4.6 billion. Nearly two-thirds of that came from the U.S. market. Yet the company's operating loss also doubled, surpassing $8 billion. So while sales are climbing, the bottom line is still deep in the red.

How Claude Makes Money

The bulk of Anthropic's revenue—about $3.8 billion—comes from usage-based billing for the Claude model. Subscription services, by contrast, brought in just $789 million, less than 20% of total revenue. That's a lopsided split, and it means the company's fortunes are tightly tied to how much businesses use its API.

Tangled Web with Tech Giants

Anthropic's ties to Amazon and Google run deep. In 2025, it earned $2.16 billion through their cloud platforms—a share that jumped from 11% in 2023 to 47%. But that convenience comes at a cost: around $351 million in channel fees paid to those same partners.

Here's the twist: Amazon and Google aren't just distributors. They're also investors, computing power suppliers, and—through their own AI models—competitors. That creates a delicate balancing act, with potential conflicts of interest and tough pricing negotiations.

Customer Concentration and Compute Commitments

Two anonymous customers accounted for 24% of Anthropic's revenue, and neither has a long-term agreement. That's a lot of eggs in a couple of baskets. Meanwhile, by the end of 2025, the company had non-cancellable computing power commitments totaling $54.6 billion. Unpaid invoices stood at $909 million, with 60% collected through intermediaries.

In plain English: Anthropic has promised to buy a massive amount of compute, and it owes a chunk of change for services already rendered.

What This Means for the AI Industry

Anthropic's story is a familiar one for top generative AI players. They've proven they can scale commercialization—revenue is real and growing. But they still face thorny challenges: limited control over distribution channels, rigid computing costs, and customers who can walk away.

Can Anthropic turn its hefty revenue into sustainable profit? That's the multi-billion-dollar question. For now, the prospectus paints a picture of a company sprinting forward, even as the finish line remains hazy.
