  "llmSummary": "Comprehensive model of EA-aligned philanthropic capital at Anthropic. At \\$380B valuation (Series G, Feb 2026, \\$30B raised): \\$27-76B risk-adjusted EA capital expected. Total funding raised exceeds \\$67B. Sources: all 7 co-founders pledged 80% of equity, but only 2/7 (Dario and Daniela Amodei) have documented strong EA connections. Early EA investors Jaan Tallinn (\\$2-6B) and Dustin Moskovitz (\\$3-9B) hold substantial stakes. Employee matching program historically 3:1 at 50% of equity, now reduced to 1:1 at 25% for new hires—\\$20-40B estimated already in DAFs. Extended scenarios: at \\$500-700B (moderate bull), EA capital reaches \\$50-140B; at \\$1T+ (strong bull), \\$70-200B+. Key uncertainty: cause allocation of non-EA founders (Brown, Kaplan, McCandlish, Clark, Olah). Timeline: employee capital 2027-2030 (IPO liquidity); founder capital 2030-2040 (gradual liquidation).",
