- Spagnuolo allegedly used confidential Google Search data to place $2.75 million in Polymarket bets between Oct 15 and Dec 4, netting roughly $1.2 million in profit.
- DOJ charged Spagnuolo with commodities fraud, wire fraud, and money laundering, while the CFTC filed a civil suit seeking restitution, disgorgement, penalties, trading bans and a permanent injunction.
- Google confirmed Spagnuolo accessed a company‑wide internal tool marked “Google Confidential” and placed him on leave pending disciplinary action.
- Polymarket and Polysights officials said the prosecution shows insider trading on on‑chain prediction markets can be detected and punished, urging stronger surveillance.
- Polymarket is now the second federal case involving insider trading on its platform, following a U.S. soldier’s alleged use of classified military info for similar bets.
Why it matters: The case gives regulators a concrete example of how insider trading on prediction markets can be pursued, prompting tighter surveillance; Polymarket must bolster compliance, while Google confronts internal policy breaches and reputational risk.
