Anthropic's Lenders Raised the Coupon From 8.5% to 10%. The Equity Market Still Wants $1.5 Trillion

Equity investors are buying a claim on Anthropic's future scale. Lenders are buying a floor under Anthropic's future bills. Those are different securities with different payoffs, and the market prices the gap between them at more than 300 basis points. Nothing about that spread is irrational. What has not been priced is which side of it is right.

The equity is not mispricing the credit —it prices a different asset, one whose payoff depends on utilization rather than on payment. The lenders own the bottom of that distribution at 10% a year. Both prices can be right, and both are.

Strip out the $72.4 billion non-cash revaluation of Anthropic's convertible notes and simple interests, and the first-half loss shrinks to $8.3 billion on $16.29 billion of revenue. Cost of revenue was $2.38 billion, implying a gross margin near 85%, and the company ended June with $131.7 billion of cash and short-term investments against $6.2 billion of total indebtedness. On the operating business alone this is an investment-grade balance sheet growing revenue fourteen-fold year over year.

Credit analysts skip Anthropic's earnings and discount the payment schedule instead. About 80% of the $518 billion — $413.7 billion by Reuters' counterparty arithmetic — must be paid whether or not Anthropic uses the capacity, and shortfalls against Alphabet and Amazon still have to be settled. The only genuinely flexible piece is the agreement with xAI for up to $84.5 billion of Nvidia capacity through 2029, largely cancellable on 90 days' notice.

That is where the 85% gross margin breaks. The chip-financing vehicles begin delivering equipment in 2027 and total indebtedness was only $6.2 billion at June 30, 2026, so almost none of the $161.2 billion of Broadcom lease obligations has touched cost of revenue yet. Equity investors capitalize a margin that has never been tested against the payment schedule the company now carries.

Read the structure rather than the headline. Of the $63 billion package lined up on Oct. 26, 2026, about $43.5 billion is senior debt arranged by Bank of America, Citi and Morgan Stanley, guaranteed by Broadcom and priced near 5.75%. Only the $18 billion junior tranche — with Blackstone anchoring about $9 billion of it — takes direct Anthropic credit risk, and it prices above 10%.

That is the real asymmetry. A missed payment does not have to impair the equity before it impairs the junior debt; it is the other way round. The senior paper is protected by Broadcom's guarantee and by the equipment's resale value, while the junior tranche and then the equity absorb Anthropic's operating risk in that order.

The same two counterparties sit on both sides of Anthropic's balance sheet. Alphabet and Amazon supply the capacity Anthropic has committed to buy for $221.1 billion, they resell Claude through their own marketplaces — 48% of first-half 2026 revenue — and they hold 58% of its receivables. Alphabet can buy up to $10 billion of Anthropic stock at the IPO price in a private placement, on top of $20 billion of notes available to it, while Amazon's $6.2 billion of convertible notes can convert into as many as 1.84 billion shares at a stake capped at 12%.

Until Anthropic stops paying, the schedule stays a financing problem rather than a counterparty problem: every dollar of the $413.7 billion of identified minimums is owed to Alphabet, Amazon, Microsoft or Broadcom, which also hold Anthropic's receivables. When the payments stop, the receivable, the lease and the equity all fail together.

CoreWeave shows what an AI infrastructure balance sheet looks like when the obligations land without the cash to meet them. At June 30, 2026 it carried $51.6 billion of debt against $6.4 billion of cash, $45.2 billion of net debt against $5.0 billion of book equity, and $1.87 billion of trailing interest expense on $7.6 billion of trailing revenue. Anthropic is the mirror image, and its rating carries the market's warning about what happens if the mirror breaks.

The roadshow can begin the week of Nov. 9, 2026 and trading could start as early as Nov. 16, with a debut targeted before Thanksgiving on Nov. 26. Pricing settles the equity's side of the gap and the rating agencies settle the credit's. Moody's, S&P Global and Fitch had not published ratings for Anthropic as of Oct. 26, and Blackstone has told investors it now expects a rating in the BB range rather than investment grade, a shift from its earlier guidance.

Over the next quarter, one price and one rating decide the gap. The price is the listing; the rating is the decision three agencies have deferred. Neither has to wait for the other, and the distance between them is the only thing that matters.

Over one to three years, the question stops being about spreads and becomes about the schedule. The company's own projection of $190-200 billion of 2028 revenue lands close to the arithmetic requirement of $518 billion of commitments, which makes the projection a schedule rather than a moonshot. The 2027 and 2028 results will show what an 85% gross margin looks like after the lease payments arrive.

Fact: Anthropic has $131.7 billion of cash, $6.2 billion of debt, $16.29 billion of half-year revenue and over $518 billion of commitments that are about 80% non-cancellable. Fact: the equity is being marketed at roughly $1.5 trillion while the company's own junior paper yields above 10%. Inference: the two prices are not contradictory, because they own different parts of one outcome — equity owns the upside of utilization, credit owns the floor of the payment schedule. Speculation: if the $190-200 billion of 2028 revenue the market is underwriting arrives, equity wins and lenders earn 10% for being early. If it does not, lenders are paid first and the equity absorbs the rest.
