Anthropic’s Net Cash: $23B With Its Notes, $132B Without

Anthropic’s S-1, filed with the SEC on 26 October 2026, shows $131.7 billion of cash, cash equivalents and short-term investments at 30 June 2026, and one large liability against it: convertible notes payable of $108,566 million. Counted as debt, those notes leave $23.1 billion of net cash; if they convert into shares at the IPO, as the filing describes, the debt line largely falls away, by our arithmetic.

A chart by Sikand Media, posted on X on 26 October and passed to us on 27 October, ranks Anthropic second among US non-financial companies in net cash after its IPO, at about $200 billion, behind Berkshire Hathaway. Its footnote says “Values are illustrative estimates; debt treatment may differ.” The debt treatment is the whole difference, and on X the cash itself is in dispute.

What the Balance Sheet Shows

At 30 June 2026 Anthropic held $112,389 million of cash and cash equivalents and $19,262 million of short-term investments, the S-1’s balance sheet shows: $131,651 million in total. On the other side were convertible notes payable of $108,566 million, within total liabilities of $117,467 million.

The filing says Anthropic had “no borrowings drawn under the revolving credit facility” at 30 June 2026, with $3.2 billion available under it. Subtracting only the convertible notes from cash and short-term investments gives $23.1 billion, by our arithmetic. Leases are not counted as debt in either figure.

What Was Posted on X

Michael Sikand (@michaelsikand) posted that the “craziest stat” from the $ANT S-1, in the post’s reading, is that it will have more cash than any other tech company on earth.

Li Daosen (@LiDaosen) argued that Anthropic’s $132 billion of cash was raised through preferred equity, SAFEs and convertible debt and, in the post’s reading of the S-1, is earmarked for more than $230 billion of compute obligations, rejecting the view that the company is financially safer than Amazon.

Whose Notes They Are

The notes outstanding at 30 June were Amazon’s. The S-1 says the rollover note under the Amazon 2023 agreement “remained outstanding with an aggregate principal amount of approximately $2.2 billion”, and “all notes issued under Amazon 2024 NPA remained outstanding with an aggregate principal balance of $4.0 billion.” That is $6.2 billion of principal, by our arithmetic.

The $108.6 billion is a fair value, not a sum owed. In an IPO, the notes convert into Class N common stock at $2.0928 a share under the 2023 agreement or $5.0478 under the 2024 agreement, or the IPO price if lower, so their value rises with Anthropic’s. The filing says its accumulated deficit “includes $113.2 billion related to changes in the fair value of our convertible notes”.

What Happens at the IPO

The S-1’s pro forma figures assume “the conversion of $ in aggregate principal amount of our outstanding convertible promissory notes into shares of Class N common stock immediately prior to the completion of this offering”, up to the amount that keeps Amazon Web Services under its ownership cap. The dollar amount is left blank in the filing.

Any balance above the cap “will automatically convert, subject to Amazon’s ownership cap, into shares of our Class N common stock at the applicable conversion price at the end of each fiscal quarter following this offering”, the S-1 says. If it still has not converted by maturity, “such balance will be repaid in cash at such maturity date.” The cap “may be waived at Amazon’s election”.

The Chart’s Other Numbers

Sikand Media’s chart adds about $70 billion of estimated net IPO proceeds to the $131.7 billion. Its footnote says that assumes a “reported ~$75B target, less fees, RSU tax withholding and any shares sold by existing holders”. The S-1 leaves the proceeds blank. The Wall Street Journal reported, citing sources, that Anthropic could raise about $100 billion at a $1.5 trillion to $2 trillion valuation.

For Alphabet, the chart shows about $144 billion: “$242B cash but $98B debt.” Alphabet’s 10-Q for the quarter to 30 June 2026 lists $242.47 billion of cash, cash equivalents and short-term investments, $98.17 billion of non-current long-term debt and $2.00 billion of current long-term debt: $142.3 billion net, by our arithmetic. We did not check the chart’s figures for Berkshire Hathaway, about $380 billion, or NVIDIA, about $66 billion.

Two Readings on X

Jukan, who posts as @jukan05, wrote on 27 October: “Anthropic has more cash and cash equivalents than Amazon… I don’t understand why people keep spreading fearmongering FUD about Anthropic going bankrupt.” Dawson Lee, who posts as Li Daosen, quoted it and argued the opposite: the $132 billion “was raised via $140B in external preferred equity, SAFEs, and convertible debt” and “The cash is legally ear-marked to fund these commitments.”

Lee wrote that the S-1 shows “over $230B in multi-year, non-cancellable compute obligations ($110B locked to Amazon AWS and $120.5B to SpaceX)”. The S-1 says Anthropic committed to spend “at least $110.0 billion between May 2026 and April 2036, regardless of actual usage” with Amazon, non-cancelable except for an uncured material breach by Amazon. The SpaceX figure is “up to $120.5 billion”, and after initial non-cancelable periods ending in January and March 2027, “each agreement may be cancelled by either party upon 90 days’ advance written notice”, the filing says.

Lee also wrote that Anthropic’s “operating cash flow is deeply negative.” The S-1’s cash flow statement shows net cash used in operating activities of $1,627 million in 2023, $5,692 million in 2024 and $2,637 million in 2025, and net cash provided by operating activities of $3,929 million in the first half of 2026. We reported that half-year figure, less capital spending, in an Update to our piece on how Anthropic’s $80.7B loss becomes a $2.7B adjusted profit. We did not check Lee’s $140 billion of capital raised.

The Risk Factor Bloomberg Flagged

Bloomberg reported that Anthropic “warned it may need to seek more financing sooner than the artificial-intelligence company had anticipated”. The S-1 says its cash and cash equivalents, cash generated from sales and amounts available under its credit facility will be sufficient “for at least the next 12 months from the date of this prospectus”, and then: “As a result of these and other factors, we may be required to seek additional financing sooner than we currently anticipate.”

It adds: “Even if we determine that additional financing is required, we may not be able to raise it on terms acceptable to us or at all. Any such financing, if completed, may be costly, dilutive, or lead to restrictions on how we operate our business.”

Connecting the Coverage

On 26 October we reported that the same Anthropic notes are a $108.6B debt and a $97.9B Amazon asset, and that Anthropic earned $762M of interest in Q2 on its $131.7B of cash. Today we reported that Anthropic’s compute leases not yet started reached $321.4 billion at 30 June, obligations that sit outside both net-cash figures.

The Structural Read

As we read it, the $108.6 billion is a measure of what the notes are worth to Amazon at Anthropic’s valuation, not cash Anthropic owes: the S-1 says the notes convert into Class N shares at the IPO, and a balance that never converts is repaid in cash at maturity; the filing also provides for cash repayment on certain liquidation transactions or events of default.

As we read it, the two posts on X answer different questions: Jukan compares cash balances, while Dawson Lee sets the cash against contracts; the S-1 gives the Amazon contract as non-cancelable and the SpaceX contracts as cancellable on 90 days’ notice after early 2027.

As we read it, the S-1’s own cash flow statement shows the first half of 2026 as the first period in the filing with net cash provided by operating activities, after three full years of cash used.

Three Implications

FOR INVESTORS COMPARING CASH PILES The S-1 leaves blank both the amount of notes converting at the IPO and the offering’s proceeds, so any post-IPO net cash figure, including Sikand Media’s about $200 billion, rests on assumptions outside the filing.

FOR AMAZON The S-1 says Amazon’s notes convert into Class N shares at the IPO up to its ownership cap, a cap the filing says Amazon may waive, with the rest converting quarterly.

FOR COMPUTE SUPPLIERS The S-1 says Anthropic’s $110.0 billion Amazon commitment applies regardless of actual usage, while its SpaceX contracts may be cancelled on 90 days’ notice after early 2027.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map and the State of AI.

The framework notes that “cloud providers now hold roughly $2.1 trillion in revenue backlog, and half of that — $1.05 trillion — comes from two cash-burning AI startups, OpenAI and Anthropic.”

As we read it, the S-1 shows the other side of that backlog: commitments such as the $110.0 billion owed to Amazon regardless of usage, held against $131.7 billion of cash. The framework predates this filing and does not discuss it.

What Is Not Established

The S-1 leaves blank how much of the $6.2 billion of principal converts at the IPO and how much the offering raises, so a post-IPO net cash figure cannot be computed from the filing. The chart’s ranking also rests on Berkshire Hathaway and NVIDIA figures we did not check.

The Bottom Line

Anthropic’s $131.7 billion of cash and short-term investments nets to $23.1 billion against $108.6 billion of Amazon convertible notes at fair value, or stays near $131.7 billion if those notes, with $6.2 billion of principal, convert into shares at the IPO, by our arithmetic from the S-1.
