Anthropic spent $12.65 billion to earn $4.59 billion in 2025, its IPO prospectus shows
Anthropic's IPO prospectus shows a 2025 operating loss of about $8 billion on $4.59 billion of revenue, a fraction of its $42 billion net loss. For anyone building on Claude, Anthropic's $20.28 billion of year-end cash covers about two and a half years of that loss.
The Scientist · Science desk
What happened
- Roughly $34 billion of the net loss was an accounting charge for a rise in the estimated value of financing that could eventually convert into Anthropic shares.
- The prospectus lists about $518 billion in obligations for cloud computing, infrastructure and related capacity.
- Nearly a quarter of Anthropic's 2025 revenue came from just two customers, according to Reuters' review of the filing.
Why it matters
- What it limits constraint At about 25 times year-end cash, the $518 billion can be met only from future revenue and new money, so the size of the eventual offering bears directly on how long Claude's supplier stays funded.
- Who has to decide decision Anthropic has warned investors that many of its largest clients lack long-term contracts and could cut or stop spending. A buyer willing to sign a multi-year Claude deal is offering the commitment the prospectus flags as missing, and can price it accordingly.
- Who's exposed exposure Public buyers would hold economic exposure with limited say over the company, because the proposed Class F share would give the seven co-founders 50.1% of voting power, subject to conditions in the filing.

At $2 trillion, Anthropic would list at about 30 times its latest quarter annualizedConfirmed23 publishers
Revenue of $4.59 billion [1] against total operating expenses of $12.65 billion [9] leaves a gap of $8.06 billion [15]. That is the operating loss The Crypto Times reports from Reuters' review [4]. The figure excludes writedowns of liabilities mostly tied to earlier fundraising [6]. Subtract it from the $42 billion net loss [2] and about $34 billion is left, roughly 81% of the total and the size of the charge on convertible financing [18]. Superpower Daily says plainly that the charge was not money spent operating the company [8]. As a measure of spending, the net loss overstates the cost of running Anthropic about fivefold [19].
For a company that builds on Claude, the operating figures are the useful ones. Compute cost about $1.60 for every dollar of revenue in 2025 [20]. That bill tripled from 2024 [10] while revenue grew roughly twelvefold [1], so compute per dollar of revenue fell to about a quarter of its 2024 level [21]. On those rounded multiples, 2024 compute ran at roughly six times revenue [22].
The thing this doesn't tell you is whether serving a Claude request costs more than the customer pays for it. The $7.33 billion is a single line, which The Crypto Times describes as the infrastructure needed to train and operate increasingly large models [13]. If serving took more than about 63% of it, serving alone cost more than the $4.59 billion customers paid [23]. Below that share, current usage covered its own compute cost.
The runway implied by year-end cash [24] treats the 2025 operating loss as cash burn. The reports do not include a cash-flow statement to check that.
The obligations are the larger unknown, and the two accounts date them differently. The Crypto Times calls the $518 billion future commitments [7]. Superpower Daily says Reuters describes plans for those obligations in the coming year, and it warns against setting the sum beside a single year of operating expenses [27]. If the coming-year reading holds, the sum is about 71 times what Anthropic spent on compute in 2025 [28].
Reuters has reported that Anthropic could seek a valuation above $2 trillion [3]. A Binance pre-IPO perpetual launched in June implied about that figure on an assumed 1 billion shares, a count the exchange says is for reference only [17]. Anthropic said in June that the share count and price had not been set [5]. Reuters previously reported that a debut was likely to move until after the November U.S. midterm elections [26].
What to watch
- Whether the public filing dates the $518 billion of obligations to the coming year or spreads them across several.
- Any split of the $7.33 billion compute bill between training and serving, or a cash-flow statement, since either would show whether current Claude usage covers its own cost.
- The offering size and share count, and whether the listing moves past the November midterms as Reuters reported.
