“While I don’t know about prepayment for services, I can confirm from a source with direct knowledge of billing that Anthropic spent $1.35 billion on Amazon Web Services in 2024, and has already spent $2.66 billion on Amazon Web Services through the end of September.”
Our reading, the sentence that was checked:
Anthropic spent $1.35 billion on AWS in 2024 and $2.66 billion through September 2025.

From the speaker
- $1.35 billion on Amazon Web Services in 2024
- $2.66 billion on Amazon Web Services through the end of September
- final cash paid to Amazon after any discounts or credits
- I don’t know about prepayment for services
Our interpretation
- September means September 2025, given the publication date and surrounding text.
- Assess calendar 2024 and January–September 2025 separately. The combined target period contains those two reporting windows.
- Spending means cash payments after discounts and credits, including any prepayments, rather than expenses recognized or services consumed.
- Use estimate as the accounting-basis classification for anonymously sourced journalistic figures; the claim does not identify a financial reporting standard.
- The nearby $1.359 billion figure indicates that $1.35 billion is approximate.
Counts as supported if: Independent records establish approximately $1.35 billion of net cash AWS payments during 2024 and approximately $2.66 billion during January–September 2025.
Counts as contradicted if: Independent records measuring the same net cash payments establish a materially different total for either reporting window.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Unresolved
The record was checked, and the evidence available by the cutoff does not settle it.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The search did not independently establish either AWS payment total. The company announcement confirms the AWS relationship, but financing and aggregate infrastructure disclosures cannot substitute for net cash payments to a named supplier. Lack of corroboration does not show that Zitron’s confidential-source reporting was false.
Limitations
- The underlying billing records are unavailable.
- Some potentially relevant pages could not be read.
- Neither component has independent decisive evidence.
Evidence (1 item)
Context only: Anthropic,
establishes AWS as our primary cloud and training partner.
Why it matters here: Confirms the commercial relationship. Amazon’s investment in Anthropic is a different cash flow from Anthropic’s AWS payments and establishes neither claimed total.

What would settle it
Authenticated AWS payment records or independent reporting establishing net cash paid in calendar 2024 and January–September 2025, with credits and prepayments reconciled.
