Anthropic-backed AI safety super PAC Public First spent over $63 million in the 2026 midterms and said 10 of its 17 endorsed congressional candidates won, per Bloomberg. Anthropic contributed roughly $20M+ to the pro-regulation group and employees added another ~$5M, with CEO Dario Amodei giving $1M personally — his first campaign contribution of the cycle. Public First outperformed the opposing accelerationist super PAC Leading the Future, which deployed roughly $100M for weaker results.
