DOJ charges Google employee over Polymarket trades : NPR

Key Points:

• Michele Spagnuolo, a Google software engineer, was arrested and charged with commodities fraud, wire fraud, and money laundering for using confidential Google search data to make $1.2 million on Polymarket, a prediction market site.
• Spagnuolo allegedly placed $2.7 million in bets on search trends for the most-Googled person of 2025, using insider information unavailable to other traders, resulting in significant profits.
• Polymarket cooperated with federal authorities, marking the second known insider trading case linked to prediction markets, which use cryptocurrency and are subject to less stringent regulations than stock markets.
• The case highlights ongoing regulatory disputes over prediction markets, with the Trump administration asserting federal oversight via the Commodity Futures Trading Commission, while states push for gambling regulation.
• Polymarket's U.S. operations were shut down in 2022 due to licensing issues, and its founder was investigated by the FBI; the platform remains controversial, with ties to the Trump family and ongoing debates over its legal status.
