A few months ago I spent $60 ordering the March 2025 version of Anthropic's certificate of incorporation from the state of Delaware, and last week I finally got around to scanning and uploading it. Here's a PDF! After writing most of this shortform, I discovered while googling related keywords that someone had already uploaded the 2023-09-21 version online here, which is slightly different.
I don't particularly bid that people spend their time reading it; it's very long and dense and I predict that most people trying to draw important conclusions from it who aren't already familiar with corporate law (including me) will end up being somewhat confused by default.

I think this means that the 3 LTBT-appointed directors do not have the abi
