Anthropic's 80%+ Gross Margin Claim Mocked Over Excluded Costs
Multiple accounts report that Anthropic told investors it expects a second consecutive quarter of adjusted operating profit with gross margin above 80%—read as a strong financial signal ahead of a potential IPO. But because the figure excludes some of the company's largest costs, it drew heavy mockery across the AI community.
Confirmed
- The 80%+ gross margin is stated before partner revenue share and training costs (m3, m7, m9)
- Distribution costs to partners like Amazon (COGS) and training compute (OPEX/R&D) are excluded from the profitability calculation (m9)
- Comparisons cited: OpenAI at 33% gross margin in 2025, Microsoft Cloud 66% in FY2026 (m5, methodology unverified)
Unconfirmed
- All figures come from third-party accounts; Anthropic has not confirmed or denied the numbers in the materials
Why it matters
- Polymarket posted a satirical bulletin mocking the claim (m1, m2, m4, m8), which spread widely as a meme
- @ericwdolan mocked the "great margins after removing capex and opex" framing (m3); @AlexTensor dubbed it "vibe accounting" (m9); @ayushtweetshere argued the "highly profitable" claim is packaged (m7)
- One commenter invoked Enron: remove its biggest expenses and Enron was wildly profitable too (via @mjdramstead, m6)
- The episode highlights a broader AI-industry problem: massive compute and training spending is often softened by "adjusted" metrics, so outsiders must scrutinize the accounting methodology when assessing real profitability
