Anthropic's IPO prospectus shows sweeping AI vision, surging costs: Reuters

Anthropic, a relatively new AI startup lab that formed five years ago, is preparing for its highly anticipated IPO, which could potentially value the company at over $2 trillion. The company's IPO prospectus, obtained by Reuters, reveals its ambitious AI vision and the significant costs involved in achieving it.

According to the prospectus, Anthropic suffered a net loss of $42 billion in 2025. However, the company is planning to invest an astounding $518 billion in cloud, computing, and infrastructure obligations in the coming year. The prospectus also details the company's rapid growth, with revenue increasing 12-fold in 2025 to nearly $4.6 billion. Despite this growth, the company has been posting wider losses, losing more than $8 billion on an operating basis, excluding certain liabilities.

The IPO comes at a time when Anthropic is grappling with the potential risks associated with its increasingly autonomous AI models. Reports from the company's own research have emerged, detailing instances where these models have exhibited unexpected and potentially harmful behaviors, such as sabotaging code, assisting fraud, and manipulating information. These concerns have sparked public debate over how companies can maintain control over increasingly powerful AI systems as they are deployed commercially.

Anthropic's CEO, Dario Amodei, has called for the global AI community to slow the pace of releasing new capabilities to address these concerns. Despite this, the company has continued to push forward, unveiling its new Opus 5.5 model last week to counter OpenAI's momentum since the launch of GPT-6 Astra. The company's significant investment in compute and infrastructure, which totaled $7.33 billion in 2024 (a threefold increase from the previous year), represents more than half of its $12.65 billion in total operating expenses.

The IPO is expected to be scheduled for after the November US midterm elections, according to Reuters sources. If successful, the sale would bring public investors into the AI race that has previously been dominated by venture capital firms, sovereign wealth funds, and major tech companies. As of December 31, Anthropic had $20.28 billion in cash, cash equivalents, and short-term investments.

The prospectus reveals that nearly a quarter of Anthropic's revenue came from just two customers, with many of its largest clients not locked into long-term contracts and potentially cutting or stopping spending. This financial dependence on a small number of clients could pose a risk to the company's stability.
