Polymarket Pulls Controversial Cornell 'Cornell 7' Betting Market

The move signals rising scrutiny of prediction markets' ethics and regulation.

Overview

  • Polymarket removed the international contract after reporting on Monday showed roughly $451,633 had been traded on a market that asked whether any of seven accused Cornell students would be charged with a felony sex crime.
  • The wager first went live Sept. 30 and targeted outcomes tied to a civil suit filed Sept. 16 by a woman identified as Jane Doe and a Tompkins County prosecutor's decision to reopen the criminal inquiry on Sept. 28.
  • Survivor advocates launched a petition and pressured high‑profile endorsers such as LeBron James to cut ties with Polymarket, citing the harm of turning an ongoing sexual‑assault matter into a tradable bet.
  • Experts warned the market created financial incentives for insiders to act or trade on nonpublic case knowledge and flagged prior suspicious betting on the platform, while Polymarket said the market offered 'data‑driven insight' before archiving it.
  • Lawmakers from both parties called for clearer rules for prediction markets, regulators differ in how they treat Polymarket's U.S. app versus its international service, and the episode raises fresh questions about platform governance and celebrity marketing ties.
