Anthropic's $518B Compute Bet: Who Wins From the AI Buildout?
Anthropic confidentially filed for its IPO back in June. But the bigger story for AI investors isn't the listing — it's the prospectus.
According to the confidential prospectus reviewed by Reuters, Anthropic has committed at least $518 billion to cloud, compute, and AI infrastructure over roughly the next decade. About 80% of it is non-cancelable — they pay whether they use the capacity or not.
That is one of the largest AI buildout commitments on record. And it's coming from a company that did $4.6B in revenue last year.
The growth story
Anthropic generated about $4.6B in 2025 revenue — roughly 12x the prior year. But growth is coming at enormous cost: compute and infrastructure spending hit $7.33B (more than half of its $12.65B in operating expenses), the operating loss topped $8B, and the reported net loss was about $42B — though roughly $34B of that was a financing-related accounting charge, not cash out the door.
