Him Too? Analyzing the Effects of Epstein Connections

The Epstein files, released between September 2025 and January 2026, offer an unprecedented window into the social and professional network of a convicted sex offender whose ties extended deep into corporate America. We construct a comprehensive sample of all S&P 500 CEOs and board members serving between 2006 and 2026 - 52,266 unique individuals - and search the 1,293,753 text-bearing documents for evidence of their contact with Jeffrey Epstein. Using large language model (LLM) classification of 117,394 matched correspondences, we identify 67,637 that indicate direct contact with 1,179 S&P 500 CEOs or directors. We then document three main findings. First, firms whose CEOs or board members appeared in Epstein-related news coverage experienced significantly negative cumulative abnormal returns of up to -8.5% over a ten-day window following the January 30, 2026 DOJ release. Second, adding Epstein-mediated ties to the firm network increases overall density and reduces average path lengths significantly, meaning that Epstein effectively wired corporate America into a denser, more tightly interconnected governance network than would have existed otherwise. Third, we show that Epstein's network transmitted norm contagion through shared board connections. Firms with more Epstein-connected CEOs or directors exhibit significantly worse ESG outcomes: each additional connection is associated with approximately 2.3 more annual governance incidents and 4.0 more total incidents.
