Microsoft and Meta Cut Claude Budgets; Anthropic's Chip Rent Holds
Monday, October 57 Min Read
Microsoft cut its staff's Claude spending by more than a third and Meta's internal Claude Code users halved, The Information reported. The same day, banks began selling a $60 billion package to fund Anthropic's Google-Broadcom chip lease, a five-year commitment that did not change.

Two stories broke on the same Monday.
One said two of Anthropic's largest corporate customers were cutting their spending. The other said Wall Street banks had started selling the largest chip financing ever, to fund Anthropic's chip rent.
The two stories land on opposite sides of the same ledger: revenue and cost.
What Was Cut
The Information broke the story; Investing.com and Yahoo Finance carried it. Earlier this year, Microsoft expected its employees to spend at least $1B a year on Anthropic models. As Investing.com put it: "That estimate has since been slashed by more than a third."
According to the reports, monthly spending caps in Microsoft's Cloud and AI division fell from $100,000 to about $10,000. Staff are being steered toward GitHub Copilot and OpenAI models.
At Meta, the number of employees using Claude Code fell from about 60,000 to 30,000. MetaCode, the company's internal-only tool, has more than 30,000 users.
Two Layers of $60 Billion
The financing for that rent hit the market the same day. According to the Financial Times, Bank of America, Citigroup and Morgan Stanley began selling the top layer of the $60B package on Monday.
The package has two parts. A $42B senior secured layer leans on Broadcom's A-minus credit rating. An $18B junior layer carries no Broadcom guarantee; Blackstone took about $9B of it.
The $60 Billion Package
- Broadcom-backed senior layer%70
- Unguaranteed junior layer%30
A bank buying the senior layer is effectively buying Broadcom's ability to pay. An investor in the junior layer is pricing whether Anthropic can pay the rent from its own revenue. Per the FT, the junior layer will launch later, possibly after Anthropic's IPO.
The chips arrive in 2027; lease payments start once the hardware is deployed. We covered Broadcom's side in our October 1 story.
The Microsoft and Meta news reads like a lost customer.
It is really a story about contract structure.
Fixed Rent, Flexible Revenue
According to the IPO prospectus seen by Reuters, about a quarter of Anthropic's revenue comes from two customers. The same document says most large customers are not on long-term contracts. They can reduce or stop spending.
The rent has no such flexibility. The commitment holds for five years. When costs are fixed and revenue moves, every drop in revenue raises the rent burden by more than its own size.
The assumption is a sensitivity test, not a forecast. The prospectus does not name the two large customers. Whether Microsoft or Meta is among them is unknown.
The dollar value of the cut is small. What matters is that two big tech companies could trim spending within months once their own tools were ready.
How the Market Read It
On Monday, Meta rose 1.90% and Microsoft 1.48%. The Nasdaq Composite gained 1.1% to a record close that day; Broadcom added 2.1%.
Sources do not tie these gains to the Claude report. But there was no selloff either. The market did not price the news as a break in demand.
Broadcom's last three months show the backdrop against which the package is being sold:

The Part That Doesn't Fit
According to the reports, customer spending on Anthropic models through Microsoft's enterprise platforms keeps growing. The cut applies only to Microsoft's own employees.
Part of Meta's decline also reflects headcount rather than demand. The company cut about 10% of its roughly 78,000-person workforce in the spring.
Microsoft is also an Anthropic investor. In November 2025 it pledged up to $5B, and Anthropic committed to buy $30B of Azure capacity.

What Remains
The senior layer will sell on Broadcom's rating. The junior layer's price will be the market's first open vote on how durable Anthropic's revenue is. More: What Is Cash Flow? and What Is an IPO?
This story is based on The Information's October 5, 2026 report as carried by Investing.com and Yahoo Finance, the Financial Times' report of the same day as carried by Investing.com, and Bloomberg's October 2 report as carried by Quartz and Advisor Perspectives. Prospectus figures come from Reuters' September 28 and October 1 reports; the Microsoft investment comes from Anthropic's November 18, 2025 announcement. Second-quarter revenue is an unaudited preliminary figure recorded on a gross basis. The customer cut in the worked example is an assumption.
