“The end of q2 and during q3 a lot changed in the developer landscape, and that is not in this prospectus”
Michael Burry, investor, in Substack chat 27 October 2026 Burry says Anthropic's IPO filing changes nothing about AI bear case (Stocktwits)
At the end of Q2 and during Q3 the developer landscape changed substantially, and Anthropic's prospectus does not reflect this.
Mixed Partly true and partly false in roughly equal measure.
What would count as true or false
Judge as of 2026-10-27. There are two parts: (a) substantial changes in the AI/software developer landscape (e.g. major competitor tool launches, shifts in pricing or market share, developer adoption moves) happened in late Q2 and during Q3 2026; (b) Anthropic's IPO prospectus (Form S-1 as filed by that date) does not reflect them. True: such changes are documented and the prospectus's financial data and risk/business discussion stop before them or leave them out. Mostly true: both hold, but the prospectus mentions the changes briefly or generically without updating figures for them. Mixed: one part clearly holds and the other is doubtful, e.g. the prospectus already contains Q3 data or discussion of the developments. Mostly false: there were some changes but they were minor, or the prospectus substantially covers them. False: no Anthropic prospectus existed, or the prospectus explicitly covers the period and developments in question. If no public Anthropic prospectus was filed, resolve false.

Reasoning
An Anthropic Form S-1 had been filed by the judging date (E1, E2). Part (a) is fairly well supported: JetBrains reports Claude Code use at work rising from 18% in January to about 39% of professional developers in May–July 2026 (E3), and Visual Studio Magazine reported a switch to usage-based Copilot billing in early June 2026 (E4). Part (b) is doubtful. Fortune's account of the prospectus cites customer revenue figures for the first nine months of 2026 (E1), so the filing's financial data covers Q3 rather than stopping before it. None of the evidence shows whether the prospectus discusses these specific developer-landscape changes.
