What to know
- Anthropic's leaked prospectus targets a roughly $2 trillion valuation while disclosing a $42 billion net loss in 2025 and plans to spend $518 billion on cloud and computing infrastructure.
- An unusually large 80 of 261 pages (nearly a third by some counts) are devoted to risk factors, including warnings that Anthropic's own AI models could pose 'catastrophic or existential risk,' resist shutdown, and behave in ways resembling blackmail.
- The filing shows nearly a quarter of 2025 revenue came from just two customers, and that Anthropic depends on cloud and compute partnerships with Big Tech firms that are simultaneously its competitors.
- Online reaction splits between bubble skepticism comparing the losses to the dot-com era, bulls citing steep 2026 revenue growth as justification, and unease that a company profits while warning its product could end humanity.
The dispute Whether the headline $42B loss figure (all from 2025) fairly represents the company's trajectory, given commenters' claims of enormous unreported 2026 revenue growth. · positions read across 237 posts and comments
The disclosed losses versus the sky-high valuation echo the dot-com bubble and other historical financial bubbles.

Revenue growth in 2026 and durable technical/enterprise moats justify the bet, and critics are being too cynical.

Commentators and social posts seize on the $42B loss figure amid the IPO push to question whether AI infrastructure spending signals a bubble.

Honest question from someone that's not onto investing nor these companies. $4.6B of 2025 revenue explodes into $11.5B in a single quarter in 2026. mapped to a year, that's equivalent to a $46B of revenue for 2026; which is 10x from 2025, and it offsets the $42B loss. That is napkin math, and also probably wrong for reasons I'm not even interested…
