From the speaker
- In 2025
- Anthropic
- $4.6 billion in revenue
- the section heading and text attribute the figures to Anthropic's S-1, as reported by Reuters
Our interpretation
- We take the accounting basis from the source he names: an S-1 reports revenue under U.S. GAAP. We read '$4.6 billion in revenue' as reported GAAP revenue for the year, not an annualized run rate.
- We read '$4.6 billion' as a figure rounded to one decimal place.
Counts as supported if: Anthropic's GAAP revenue for the year ended 2025-12-31 rounds to $4.6 billion.
Counts as contradicted if: Anthropic's GAAP revenue for the year ended 2025-12-31 does not round to $4.6 billion.
Retrospective: these criteria were written after the outcome was public.

Rationale
On September 29, 2026, Zitron wrote that Anthropic had $4.6 billion in revenue in 2025, citing figures from its S-1. The S-1, filed on October 26, 2026, reports revenue of $4,585 million for the year ended December 31, 2025, in audited statements prepared under U.S. GAAP. That is $4.585 billion, which rounds to $4.6 billion.
Limitations
- Zitron's source was a Reuters report on a leaked draft. The record checks his figure against the S-1 as filed.
- This record assesses reported 2025 revenue only. It does not assess run-rate figures for 2025 or any 2026 period.
Evidence (1 item)
Supports the claim: Anthropic, PBC (Form S-1, filed with the SEC),
Year Ended December 31, Six Months Ended June 30, 2023 2024 2025 2025 2026 (unaudited) Revenue $41 $386 $4,585
Why it matters here: The S-1 reports revenue of $4,585 million for the year ended December 31, 2025, which is $4.585 billion and rounds to $4.6 billion. The independent auditor's opinion states that these statements are in conformity with U.S. GAAP.
