Anthropic’s November 2 amended IPO filing put its aggregate purchase commitments and leases at about $895.4 billion, substantially all related to compute and infrastructure.13 The disclosure highlights the scale of the AI buildout—and why large customer commitments alone cannot prove that the companies financing new capacity will earn attractive returns from it.
Microsoft shares rose, but less than Oracle and CoreWeave
On November 3, market reports described Microsoft shares as up about 2%, while Oracle rose about 6% after pricing a $20 billion stock-and-bond sale and CoreWeave gained about 7%.8 A separate report recorded Microsoft up 1.34% to $513.89 at 10:45 a.m. ET, so these figures are intraday snapshots rather than confirmed closing returns.
6 The available reports do not establish the closing move or independently confirm the prior session’s reported decline.
The stock moves provide market context, not proof that a particular deal or spending plan will produce returns. The more important question is whether new AI capacity can be financed, delivered, filled with paying demand and operated profitably.
What Anthropic disclosed about its compute commitments
The amended filing reported approximately $895.4 billion in aggregate purchase commitments and lease agreements, with “substantially all” related to compute and infrastructure.13 Among the large cloud-provider commitments reported from the filing are at least $44.9 billion to Microsoft through June 2033, approximately $121.3 billion to Google, and at least $110 billion to Amazon.

The available reporting does not establish that the earlier $31.4 billion figure and the amended Microsoft figure use identical scope or terms, so the two should not be treated as directly comparable without that qualification.
Nor is every disclosed commitment equivalent to capacity already available. Reporting on the filing describes arrangements that depend on counterparties securing financing, facilities or approvals, and some commitments have termination rights.58
55 Those conditions create a risk that contracted capacity could be delayed or fail to begin as planned.
How the $44.9 billion Microsoft deal compares with its backlog
Microsoft reported $677 billion in commercial remaining performance obligations (RPO), its measure of contracted future revenue not yet recognized.21 Anthropic’s $44.9 billion minimum commitment is about 6.6% of that figure by simple arithmetic. But they measure different things: Anthropic’s figure is a customer commitment to spend with Microsoft, while Microsoft’s RPO is contracted revenue across its commercial business. The comparison gives a sense of scale; it does not mean the Anthropic deal is all included in RPO, or that the two figures should be added together.

Growth is strong; infrastructure still has to pay off
Microsoft’s fiscal first-quarter results for the period ended September 30 showed revenue of $92.3 billion, up 19%, and GAAP net income of $36.6 billion.21 Microsoft Cloud revenue was $63.9 billion, up 30%, while Azure grew 48%.
21
26 Those results show substantial growth alongside the infrastructure race.
Microsoft also reported $45.2 billion in capital expenditures for the quarter and said some expected third-party capacity deliveries were delayed.20 It added 24 data centers across five continents. For the second quarter, management forecast revenue of $96 billion to $97.1 billion and capital spending above $50 billion.
20
32 Reported free cash flow was about $18.6 billion for the quarter.
36
The figures point to a two-sided investment case: cloud growth and customer commitments support continued expansion, while heavy spending and delivery constraints make the timing and economics of that expansion important. Revenue growth and backlog show opportunity, but they do not by themselves establish that returns will exceed the costs of building, financing and operating the infrastructure.
