Anthropic's S-1 reveals $16B H1 2026 revenue, 85% gross margin, shrinking data spend

Anthropic has filed its S-1 for a proposed IPO. @fleetingbits breaks down the key numbers: $16B revenue in H1 2026 with 85% gross margins; $6.6B spent on R&D compute; overall compute margins of 45%. Gross margin trajectory is dramatic: 36.6% in 2023, −94.8% in 2024, 39.5% in 2025, 85% in H1 2026 — and the author argues the business is not fully optimized yet. Estimated data vendor spending was $165M in 2024, $330M in 2025, $388M in H1 2026 (on trend for $936M in 2026). As a share of R&D compute spend, purchased data has steadily declined: 9.3% → 7.2% → 5.9%, suggesting bought data is becoming progressively less critical to progress.
