- Michele Spagnuolo, a Google engineer, was charged by US prosecutors with insider trading for allegedly exploiting internal search data to profit $1.2 million on Polymarket bets about Google's annual Year in Search rankings
- The DOJ (SDNY) brought criminal charges while the CFTC filed a parallel civil action, making this one of the first insider trading prosecutions targeting a prediction market trader using corporate insider data
- The Next Web reports Spagnuolo wagered $2.7 million in total on Polymarket — a figure most outlets bury in favor of the $1.2 million profit number
- Coverage spanned every major beat on May 27-28, 2026, with ABC News, NPR, Reuters, Bloomberg, WSJ, BBC, Wired, and The Verge all running the story
- The alleged scheme hinged on Spagnuolo placing bets on search terms and trends before Google's Year in Search rankings went public, exploiting his role giving him advance visibility into the data
Why it matters: The CFTC's parallel civil action alongside DOJ criminal charges signals that prediction markets now fall under traditional insider trading enforcement — a precedent that could force platforms like Polymarket to police employee data leaks from corporate partners. Google's internal search data, never before tested as 'inside information' in court, becomes the legal battleground that may redefine what counts as material non-public information in the age of prediction markets.
