Anthropic’s S-1 reports a net loss of $80.7 billion for the six months ended June 30, 2026. $72.4 billion of that, 90%, is a non-cash fair-value charge on convertible notes and SAFEs, according to the filing’s own breakdown. That single fact separates how bad Anthropic’s accounting looks from how bad its business is.
The mechanism is standard GAAP mark-to-market at unprecedented scale. Convertible notes and SAFEs convert into equity at a discount to whatever Anthropic is worth at conversion; when a later round marks the company up, like the roughly $965 billion private valuation 247wallst.com reported from May 2026, the notes’ fair value gets marked up to match on the liability side of Anthropic’s own books, and the increase is booked as a loss though no cash leaves. That is most of why reported net loss jumped from $42.0 billion for all of 2025 to $80.7 billion in just the first half of 2026, a figure covered when that filing first surfaced.

Based on Anthropic S-1 filing
Strip the markup out and revenue was $16.29 billion in the first half of 2026, up 1,304% from $1.16 billion a year earlier, CNBC reported. Cost of revenue was $2.38 billion, an 85% gross margin versus an implied 12% a year earlier. Compute cost per dollar of revenue fell from about $1.60 in 2025 to about $0.55, the Motley Fool calculated from the filing, a mix of volume pricing, newer chips, and more fixed-price enterprise deals.
GAAP operating loss for the half was $690 million, not $80.7 billion; Q2 alone posted a GAAP operating profit of $974 million, an 8% margin, Anthropic’s first profitable quarter. On an adjusted basis, stripping stock compensation, non-cash charitable giving and legal settlements, operating income was $1.6 billion, a 10% margin. Third-quarter revenue hit $16.8 billion, up roughly 45% on Q2, and the company told prospective investors it stayed adjusted-profitable for a second straight quarter.
That sequential rate is the thing to watch, not the headline annual one: about 144% growth from Q1 to Q2, then about 47% from Q2 to Q3, per CNBC’s tally. “What the prospectus didn’t tell us is management’s expectations around the sequential slowdown in the growth rate,” Michael Field, chief equity strategist at Morningstar, told CNBC. Violeta Todorova of Leverage Shares put the open question plainly: “It is unclear how much it costs to generate each additional dollar of revenue as computing demand increases.”
The filing never adds up one total for promised compute payments, and that is itself informative. As of June 30, 2026, fixed or minimum purchase commitments were $265.6 billion, terms of one to 20 years, plus $321.4 billion of leases signed but not commenced, according to the S-1. At the end of 2025 those lines totaled about $105 billion combined; after June 30 came roughly $245 billion more. Named counterparties include at least $114.5 billion with Google through July 2033, $161.2 billion of Broadcom equipment leases, up to $120.5 billion with SpaceX’s AI subsidiary (paid $3.1 billion a month, per CNBC), at least $110 billion with Amazon Web Services through April 2036, and $44.9 billion with Microsoft Azure. Analysts tallying the named deals plus estimated Google TPU and AMD capacity arrived at roughly $780 billion to $810 billion, ZeroHedge calculated; a leaked draft had put the rolling tab at $518 billion in September. The gap is scope, not disagreement: one analysis noted the S-1 itself never states one consolidated number.
Even the low-end $265.6 billion is roughly 12 times third-quarter revenue annualized at $67.2 billion and about six times the $131.7 billion of cash and short-term investments. “Investors can see compute falling as a share of revenue, but not how much of the forward commitment is earmarked for training the next generation of models versus serving customers,” Nick Patience, AI lead at the Futurum Group, told CNBC. “That split dictates future margins.” The filing separately admits Anthropic has sought “quantities of compute from [cloud service providers] in excess of what those partners were willing to provide” and has “historically operated in a compute-constrained environment.”
Control sits with seven people. Dario Amodei and his six co-founders each hold a Class F share worth 50.1% of total voting power on any shareholder matter, a structure Anthropic calls one with “no direct public company precedent”; a related filing disclosure lays out a ranked line of succession for that power. “We also know now that management plans a series of different class share issues,” Field said. “But what we don’t know is whether investors will be fine with the lack of control implied.”
Anthropic filed into the worst week for AI-capex credibility of the year. Microsoft cut its 2026 capex forecast to $170 billion from $175 billion, posted free cash flow of $18.6 billion, down a second straight quarter, and priced $25 billion of bonds on Thursday, its first US bond sale since 2017, drawing over $115 billion in orders. Amazon reported negative free cash flow of $42.4 billion over the trailing 12 months, negative a second consecutive quarter, while reiterating roughly $220 billion in 2026 capex. Alphabet’s capex hit a record $51.4 billion, more than double a year earlier, and free cash flow came in at negative $9.1 billion against an expected negative $2.7 billion; the stock fell 12.6%, erasing roughly $500 billion in its worst trading day since its 2004 listing. Intel fell 29% on a weak forecast, its steepest one-day drop since 1974, wiping out roughly $150 billion and dragging the semiconductor sector down with it.
| Company | 2026 capex guidance | Latest free cash flow |
|---|---|---|
| Microsoft | $170bn, cut from $175bn | $18.6bn, down for a 2nd straight quarter |
| Amazon | ~$220bn, reiterated | -$42.4bn over trailing 12 months, negative 2nd straight quarter |
| Alphabet | up to $205bn, maintained | -$9.1bn, negative 2nd straight quarter, vs -$2.7bn expected |
| Oracle | new outside funding capped at $20bn for FY2027 | -$23.7bn in FY2026; forecast positive from H2 FY2028 |
Oracle pushed back against the panic. At its October 28 investor day, CFO Hilary Maxson said the company would cap new outside fundraising at $20 billion, split evenly between debt and equity, to finish funding its build-out through fiscal 2027, with free cash flow turning positive in the second half of fiscal 2028 and topping $30 billion in fiscal 2029. The stock jumped more than 12%; analysts at Citizens wrote the announcement “put the biggest investor fear to rest — that funding its enormous AI infrastructure buildout would require an open-ended increase in debt and equity issuance.”
The net market effect was still negative: the Nasdaq fell 2.9% on Friday, its first three-week losing streak since March. “It’s been an ugly reporting season for tech thus far,” Jonathan Krinsky of BTIG wrote, dubbing it “The Techsas Chainsaw Massacre.” Wharton’s David Hsu asked the underlying question: “It’s a great technology, seems to do things that we never would have imagined, but how does that then translate into a viable business?” Daniel Newman, CEO of Futurum Group, still called Anthropic’s prospectus “very impressive” on 1,300% annual sales growth, 900% net revenue retention and an 85% gross margin: “Anthropic is the IPO market at this point. I think companies would have to be extremely cautious, if not just foolish, to actually want to come out in this period.”
Estimates for the listing had ranged from $1 trillion to $2 trillion. After an investor day with Amodei and finance chief Krishna Rao, some investors pushed for a target closer to $1.5 trillion, Investing.com reported, a 25% cut from the figure floated earlier. At $1.5 trillion Anthropic would trade at roughly 22.3 times Q3 revenue annualized at $67.2 billion; at $2 trillion, 29.8 times. Both are a step up from the roughly $965 billion of its last private round in May 2026. The roadshow is expected to launch the week of November 9, run by Goldman Sachs and Morgan Stanley, with trading potentially starting mid-November.
It arrives into an IPO market frozen since SpaceX’s June offering: Oura, Firmus and SK Hynix’s Solidigm have postponed or abandoned plans; Nscale and SoftBank’s SB Energy have gone silent for weeks. The number to watch is where pricing lands inside the $1.5 trillion to $2 trillion range, and whether compute cost per revenue dollar keeps falling as the first installments of $265.6 billion, or $780 billion depending whose count you use, come due regardless of top-line growth.
