All seven Anthropic cofounders—Dario and Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah—have pledged to give away 80 percent of their roughly $3.7 billion fortunes right now. Their timing ties to Anthropic’s staggering valuation jump: from $4.1 billion at Claude’s launch in spring 2023 to about $350 billion today. That pledge could channel tens of billions into philanthropy, and its backing grows as Anthropic talks with investors who might push the value higher still. Dario Amodei’s 38-page essay “The Adolescence of Technology” warns that unchecked AI will test society’s limits. He notes Elon Musk’s $700 billion fortune already outstrips John D. Rockefeller’s Gilded Age wealth relative to GDP—and that’s before AI drives 10–20 percent annual GDP growth. Amodei lays out four core risks: rogue autonomous systems, bioterror misuse, authoritarian exploitation and massive job losses. He predicts half of entry-level white-collar roles disappearing within five years. Beyond founders’ pledges, Anthropic staff have committed company shares worth billions, with the business matching those donations. It’s a stark contrast to tech titans who sign but don’t fulfill The Giving Pledge. Amodei calls that cynicism out and treats philanthropy as an insurance policy against societal breakdown—“you don’t give away billions unless you believe the alternative is pitchforks outside your house.” He goes further by arguing for robust progressive taxes on AI-generated wealth. Voluntary giving won’t cover the scale of trillion-dollar firms and a displaced workforce. Anthropic even considers keeping staff on payroll after their economic value fades—a form of corporate UBI. In Amodei’s view, heavy taxation isn’t a burden on property rights but a necessity to prevent collapse.
