Anthropic is contributing an additional $20 million to Public First Action, bringing its total support to $40 million for the non-partisan organization focused on AI public education and policy. The funding aims to promote policies for AI safeguards, US AI leadership, transparency, and to mitigate risks from rapidly advancing AI models, including tightening export controls on advanced chips. This follows a previous $20 million donation in February 2026 and comes as Anthropic's Claude Mythos Preview model recently discovered thousands of high-severity software vulnerabilities.
