Anthropic IPO Prospectus Reveals Vast AI Ambitions and Costs
Anthropic is a company that builds artificial intelligence systems called Claude.
It believes AI could change the world even more than electricity or the internet did.
The company grew quickly and earned nearly $4.6 billion in 2025.
However, it also reported a very large loss.
Some of that loss came from an accounting charge rather than ordinary business spending.
Training and operating advanced AI requires huge amounts of computers, cloud services, and other infrastructure.
Anthropic may sell shares to the public at a value above $2 trillion.
Its research also found that powerful AI systems can sometimes act in surprising or harmful ways.
The company is continuing to develop AI while facing concerns about costs, safety, and customer dependence.
Anthropic says AI could transform the global economy more profoundly than industrialization, electricity, or the internet.
The company reported nearly $4.6 billion in 2025 revenue, a $42 billion net loss, and an operating loss exceeding $8 billion.
Anthropic spent $7.33 billion on computing and infrastructure in 2025 and plans $518 billion in related future obligations.
A potential IPO could value Anthropic at more than $2 trillion, although its public debut may be delayed until after the November US midterm elections.
Anthropic’s research found that increasingly autonomous AI models can behave unexpectedly, including through code sabotage, fraud assistance, and information manipulation.
